Is connected to an accumulator 16 provided on the suction side of the compressor 11.

  The air conditioner 1 also includes an indoor unit 100 disposed indoors, and an outdoor unit 200 connected to the indoor unit 100 by a refrigerant pipe 17, a tube duct 18, and a signal line 19 and disposed outside the room. .

  The indoor unit 100 includes an indoor heat exchanger 13, an indoor fan 20 for sending air to the indoor heat exchanger 13, an indoor fan motor 21 that drives the indoor fan 20, and an indoor control that controls the indoor fan motor 21. For example, the indoor controller 22 includes a wireless remote controller (hereinafter referred to as a remote controller) 23 for a user to give an operation mode instruction of the air conditioner 1 and a discharge portion of the tube duct 18.

  The outdoor unit 200 houses the compressor 11, the four-way valve 12, the decompression device 14, and the outdoor heat exchanger 15 described above. The outdoor unit 200 detects a discharge temperature of the compressor 11 and a high-temperature heat exchanger 24 for a high-temperature refrigerant discharged from the compressor 11 in the refrigerant pipe 17 between the compressor 11 and the four-way valve 12. A discharge temperature sensor 25, an inverter device 26 that controls the rotational speed of the compressor 11, and an outdoor controller 27 that controls the inside of the outdoor unit 200. For example, the discharge temperature sensor 25 is configured to detect an abnormal increase in the discharge temperature of the compressor 11 and to transmit detection information to the outdoor controller 27. Further, the discharge temperature sensor 25 is formed to always detect the discharge temperature of the compressor 11 in order to control the rotation speed of the compressor 11 by the outdoor controller 27.

  The inverter device 26 is provided with a heat sink 28 for dissipating heat of the inverter device 26 and a heat sink temperature sensor 29 for detecting the temperature of the heat sink 28.

  The outdoor controller 27 is connected to the discharge temperature sensor 25, the inverter device 26, and the heat sink temperature sensor 29, and further connected to the indoor controller 22 and the signal line 19 described above.

  As illustrated in FIGS. 2 and 3, the outdoor unit 200 includes a vertical partition plate 30 for partitioning in the vertical direction. With the vertical partition plate 30, the outdoor unit 200 is partitioned into a heat exchanger chamber 31 and a compressor chamber 32. The heat exchanger chamber 31 includes an outdoor heat exchanger 15, an outdoor fan 33 for allowing the outdoor heat exchanger 15 to ventilate, and an outdoor fan motor 34 for rotating the outdoor fan 33. A ventilation path F is further formed through the exchanger 15 and the outdoor fan 33 for ventilation to the outside.

  The compressor chamber 32 includes a horizontal partition plate 35 that partitions horizontally, and the compressor chamber 32 is vertically divided by the horizontal partition plate 35. Below the compressor chamber 32, the compressor 11, the four-way valve 12, the pressure reducing valve 14, the accumulator 16, and the inverter device 26 are arranged.

  At the upper part of the compressor chamber 32, an adsorption body 38 connected to the rotary motor 36 via the rotary shaft 37 and rotated by the rotary motor 36 is provided as an adsorption rotor. The adsorbent 38 adsorbs moisture by allowing air to pass through, and desorbs the adsorbed moisture by allowing air heated to a higher temperature (hereinafter referred to as “heated air”) to pass through the adsorbing portion that has adsorbed moisture. Is formed.

  The upper portion of the compressor chamber 32 has an adsorption ventilation path 39 provided so that air containing water passes (ventilates) approximately 3/4 of the surface area of the adsorbent body 38, and approximately 1/4 of the surface area of the adsorbent body 38. A desorption ventilation path 40 provided so that heated air for desorption of moisture passes (ventilates) is formed by a ventilation path partition frame 41.

  The adsorbent 38 is disposed so as to be exposed to the adsorption ventilation path 39 and the desorption ventilation path 40. For this reason, in the adsorbent 38, moisture is adsorbed by using a portion located on the adsorption ventilation path 39 as an adsorption portion. In addition, desorption of moisture is performed by using a site located on the desorption ventilation path 40 of the adsorbent 38 as a desorption part. Further, as described above, the adsorbent 38 is rotated by the rotary motor 36, and the adsorbent 38 rotates between the adsorption ventilation path 39 and the desorption ventilation path 40. By this rotational movement, the adsorbent 38 is formed so that the adsorbing part and the desorbing part can be switched.

  The adsorption ventilation path 39 includes an adsorption ventilation path suction port 42 for sucking outdoor air, an adsorption ventilation path filter 43 provided in the adsorption ventilation path suction port 42 so that dust does not enter the adsorption ventilation path 39, and An adsorbing portion of the adsorbing body 38 that adsorbs moisture in the air that has passed through the adsorbing air passage filter 43, an adsorbing air passage outlet 44 for discharging the air in which the moisture is adsorbed on the adsorbing body 38 to the outside, and an adsorption A suction fan 45 for passing air from the suction ventilation path suction port 42 to the suction ventilation path discharge port 44 is sequentially arranged in the ventilation hole 39. By operating the suction fan 45, an air flow S is generated in the suction ventilation path 39. Here, the adsorbent 38 is formed of high-strength and high-density paper or an integrally molded resin material.

  The desorption ventilation path 40 includes a desorption ventilation path suction port 46 for sucking outdoor air, and a desorption ventilation path formed in the desorption ventilation path 40 so as to prevent dust from entering the desorption ventilation path 40. A filter 47, a heat sink 28 of the inverter device 26 that is cooled by air that has passed through the filter 47 for the desorption air passage, a high-temperature heat exchanger 24 that further passes the air that has passed through the heat sink 28, a heat sink 28, The desorbing part of the adsorbent 38 that allows the heated air that has become high temperature by passing through the heat exchanger 24 and the air that has passed through the desorbing part of the adsorbent 38 to the indoor unit 100 via the tube duct 18. And a desorption fan 48 for blowing air are sequentially arranged. By operating the desorption fan 48, an air flow T is generated in the desorption ventilation path 40.

  The inverter device 26 is configured such that the rotational speed of the compressor 11 can be driven at a variable speed in accordance with the air conditioning load such as the room temperature, the setting state by the remote controller 23 and the indoor / outdoor temperature.

  In the air conditioner 1 configured as described above, when the heating operation is performed, the heating operation instruction signal R is transmitted to the indoor controller 22 by the remote controller 23. When the indoor controller 22 receives the heating operation instruction signal R, the indoor controller 22 transmits the heating operation instruction signal R to the outdoor controller 27. Next, the inverter device 26 is operated by the outdoor controller 27. The inverter device 26 drives the compressor 11 and controls the rotational speed of the compressor 11 according to the air-conditioning operation status. The refrigerant thus compressed is discharged from the compressor 11 and passes through the indoor heat exchanger 13 via the high-temperature heat exchanger 24 and the four-way valve 12 as indicated by the refrigerant flow H. At this time, the indoor fan motor 21 drives the indoor fan 20, and the air blown from the indoor fan 20 is blown into the room through the indoor heat exchanger 13. Thereby, the room and the indoor heat exchanger 13 exchange heat, and the room is warmed.

  The refrigerant that has passed through the indoor heat exchanger 13 is expanded by the decompression device 14 and passes through the outdoor heat exchanger 15. The refrigerant that has passed through the outdoor heat exchanger 15 is heated by the outdoor fan 33 to exchange heat with the outside, and returns to the compressor 11. The refrigerant flow H is during the heating operation, and the refrigerant flow during the cooling operation is changed to the refrigerant flow C by switching the four-way valve 12.

  Next, the humidification operation will be described. First, a humidifying operation instruction signal is transmitted to the indoor controller 22 by the remote controller 23. When the indoor controller 22 receives this instruction signal R, the indoor controller 22 transmits the instruction signal R to the outdoor controller 27. When the outdoor controller 27 receives the humidifying operation instruction signal, the outdoor unit 200 first operates the suction fan 45. By driving the suction fan 45, an air flow S is generated in the suction ventilation path 39. The air flow S passes through the adsorbing portion of the adsorbent body 38, so that moisture contained in the air is adsorbed on the adsorbent body 38.

  The outdoor controller 27 rotates the rotary motor 36 after the suction fan 38 is operated. The rotary motor 36 is set so that the adsorbent rotates once in a certain time, for example, 2 minutes. Subsequently, the outdoor controller 27 determines whether or not a preset time set in the outdoor controller 27 has elapsed since the start of the operation of the refrigeration cycle including the compressor 11. This determination is to determine whether the heating operation or the like is performed for 3 minutes or more when the set time is 3 minutes.

  Here, when the heating operation is performed for 3 minutes or more, the desorption fan 48 is operated. By operating the desorption fan 48, an air flow T is generated in the desorption ventilation path 40. As shown in the air flow T, the outside air is sucked into the desorption air passage 40 by the desorption fan 48 and is warmed by sequentially passing through the heat sink 28 and the high temperature heat exchanger 24.

  This warmed outside air (hereinafter referred to as heated air) passes through the desorption part of the adsorbent 38. In the desorption part of the adsorbent 38, the adsorbent 38 containing moisture adsorbed by the adsorbing part is rotationally moved to the desorption part by the rotary motor 36, so that the desorption part contains moisture. Become. For this reason, when the heated air passes through the desorption portion of the adsorbent body 38, the moisture is desorbed to become air containing moisture (hereinafter, humidified air).

  This humidified air is discharged to the indoor unit 100 through the tube duct 18 by the operation of the desorption fan 48. The humidified air discharged to the indoor unit 100 is mixed with warm air blown indoors by the indoor fan 20 via the indoor heat exchanger 13 and blown indoors.

  The adsorbent 38 is set so as to rotate once by a rotation motor 36 after a predetermined time has elapsed, whereby the adsorbent 38 containing moisture is always located in the desorption portion, and humidification is continuously performed. .

  In order to desorb moisture from the adsorbent 38, heated air needs to pass through the adsorbent 38. When the desorption fan 48 is operated in a short time from the start of operation of the refrigeration cycle such as the compressor 11, the air passing through the desorption ventilation path 40 reaches the desorption temperature until the temperature of the high-temperature heat exchanger 24 rises. There is a possibility not to. When this air passes through the adsorbent body 38, not only the moisture of the adsorbent body 38 is desorbed, but also the cold air that has passed through the tube duct 18 is blown into the room despite the heating operation. In order to prevent this, the outdoor controller 27 controls the operation of the desorption fan 48 to be delayed by a predetermined time from the operation of the refrigeration cycle (compressor).

  The humidification operation is basically an operation performed to prevent a decrease in indoor humidity during the heating operation. However, since the high-temperature heat exchanger 24 is provided between the compressor 11 and the four-way valve 12, the high-temperature heat exchanger 24 is heated even during the cooling operation. For this reason, by providing the remote control 23 with a humidifying operation button during cooling operation, the humidifying operation can be performed even during the cooling operation.

  As described above, according to the air conditioner 1 according to the first embodiment, the humidifying operation can be continuously performed by slowly rotating the adsorbent 38 using the rotary motor 36. Further, as a heating means for heating the air sucked by the desorption fan 48, a heater is not provided, but a high-temperature heat exchange in which the heat sink 28 of the inverter device 26 and the refrigerant discharged from the compressor 11 flow on the desorption air passage 40. A container 24 is placed. Thus, power consumption can be reduced by using the heat sink 28 and the high temperature heat exchanger 24 as heating means. In addition, since the heat sink 28 can be cooled at the same time, the energy efficiency can be improved and energy saving can be achieved. Moreover, since the high-temperature heat exchanger 24 has the highest temperature in the refrigeration cycle, the use of this heat makes it possible to raise the temperature of the heated air and improve the humidification performance.

  Moreover, since the rotation speed of the compressor 11 is controlled using the inverter device 26, the compressor 11 is hardly stopped during each air conditioning operation. If the compressor 11 is not stopped, the operation of the refrigeration cycle is hardly stopped. For this reason, the temperature of the high-temperature heat exchanger 24 does not decrease. Since the high temperature heat exchanger 24 is provided in the refrigerant pipe 17 on the discharge side of the compressor 11, the temperature of the high temperature heat exchanger 24 decreases when the compressor 11 stops. When the temperature of the high-temperature heat exchanger 24 decreases, the temperature of the heated air also decreases, and moisture cannot be desorbed from the adsorbent 38. From these facts, the compressor 11 is controlled by using the inverter device 26 so that the compressor 11 is hardly stopped, and a substantially continuous humidification operation can be performed. It can be.

  Next, as a modification of the air conditioner 1 according to the first embodiment, a description will be given of the same configuration as that of the air conditioner 1 and a method for operating the desorption fan 48 being changed. In this modification, the outdoor controller 27 determines the operation of the desorption fan 48 based on the temperature detected by the discharge temperature sensor 25 to determine whether a predetermined time has elapsed in order to drive the desorption fan 48.

  For example, the temperature of the high temperature heat exchanger 24 when the heated air heated by the high temperature heat exchanger 24 reaches a temperature at which the adsorbent 38 can be desorbed is set in the outdoor controller 27 in advance. When the detected temperature of the discharge temperature sensor 25 exceeds the set temperature, the outdoor controller 27 instructs the desorption fan 48 to operate.

  By performing such control, it becomes possible to operate the desorption fan 48 at a temperature at which moisture can be desorbed from the adsorbent 38, and energy such as power consumption necessary for driving the desorption fan 48. Can be reduced. Further, since it is not necessary to operate the desorption fan 48 in a state where it cannot be desorbed, it is possible to prevent cold air that has not been humidified during the heating operation from being sent into the room.

  FIG. 4 is an explanatory view schematically showing the outdoor unit 200A used in the air conditioner 1A according to the second embodiment of the present invention from the side, and FIG. 5 is an explanatory view schematically showing the upper side of the outdoor unit 200A. It is. 4 and 5, the same functional parts as those in FIGS. 1 to 3 are denoted by the same reference numerals, and detailed description thereof is omitted.

  An air conditioner 1A according to the second embodiment includes an outdoor unit 200A. The outdoor unit 200A includes a vertical partition plate 49 that vertically divides the interior into a heat exchanger chamber 31 and a compressor chamber 32, and a rotary shaft 37 and a honeycomb-shaped hole formed in the vertical partition plate 49 in the horizontal direction. And an adsorbing body 50 provided so that the adsorbing part and the detaching part are divided by the vertical partition plate 49. The rotating shaft 37 faces the horizontal direction.

  The heat exchanger chamber 31 includes an outdoor heat exchanger 15, an adsorbing part of the adsorbing body 50, an outdoor fan 33 for ventilating the adsorbing part of the adsorbing body 50 and the outdoor heat exchanger 15, and the outdoor fan 33. And an outdoor fan motor 34 for rotation. Further, in the heat exchanger chamber 31, the outdoor fan 33 is operated to ventilate the outdoor passage approximately F of the surface area of the adsorbent 50 and the ventilation path F that ventilates from the outdoor to the outdoor through the outdoor heat exchanger 15 and the outdoor fan 33. And an adsorption ventilation path (adsorption air flow) S provided so that the air passes through (ventilation). An adsorbent filter 51 is provided so as to cover the adsorbing portion of the adsorbent 50 (adsorbent 50 located in the heat exchanger chamber 31) and prevent dust from entering the adsorbent 50.

  The compressor chamber 32 is provided with a horizontal partition plate 35 that partitions the inside horizontally, and the compressor chamber 31 is divided into upper and lower portions by the horizontal partition plate 35. A compressor 11, a four-way valve 12, a pressure reducing valve 14, and an accumulator 16 are disposed below the compressor chamber 31.

  In the upper part of the compressor chamber 31, a desorption part for the adsorbent 50 that is rotated by the rotary motor 36 is provided. The adsorbent 50 is moved to the position of the desorption part by the rotation of the adsorbing part that adsorbs moisture by allowing air to pass through the rotary motor 36. By allowing it to pass through, the adsorbed moisture is formed so as to be desorbable at the desorption portion. The adsorbing body 50 is formed so as to be able to be sequentially switched between the adsorbing part and the desorbing part by rotating by the rotary motor 36.

  In the upper part of the compressor chamber 31, a desorption ventilation path 52 provided so that heated air for desorption of moisture passes through approximately 1/2 of the surface area of the adsorbent 50 is passed (ventilation). 53.

  The desorption ventilation path 52 includes a desorption ventilation path suction port 54 for sucking outdoor air, a desorption ventilation path filter 55 provided in the desorption ventilation path suction port 54, and the desorption ventilation path filter 55. A high-temperature heat exchanger 24 that makes high-temperature heated air by passing the air that has passed through, a heat sink 28 of the inverter device 26 that is cooled by the air that has passed through the high-temperature heat exchanger 24, and heating that is heated to a high temperature by the heat sink 28 A desorption part of the adsorbent 50 that allows air to pass therethrough and a desorption fan 48 that blows the air that has passed through the desorption part of the adsorbent 50 to the indoor unit 100 via the tube duct 18 are sequentially arranged. By operating the desorption fan 48, an air flow T is generated in the desorption air passage 52.

  In the air conditioner 1 </ b> A configured as described above, when performing a humidifying operation, a humidifying operation instruction signal is transmitted from the remote controller 23 to the indoor controller 22. When the indoor controller 22 receives this instruction signal R, the indoor controller 22 transmits the instruction signal R to the outdoor controller 27. When the outdoor unit controller 27 receives the instruction signal for the humidifying operation, the outdoor unit 200 </ b> A determines the elapsed time after the outdoor fan 33 is driven by the outdoor controller 27.

  Since the adsorbing part of the adsorbing body 50 is disposed in the heat exchanger chamber 31, outdoor air is passed through the ventilation path F and the adsorption ventilation path S when the outdoor fan 33 is driven. At this time, the outdoor air passing through the suction ventilation path S passes through the adsorption section of the adsorption body 50 through the adsorption body filter 51. The outdoor air passes through the inside of the honeycomb-shaped adsorbent 50 provided in the adsorbing portion, so that moisture contained in the air is adsorbed to the adsorbent 50. At this time, since the adsorbent 50 has a honeycomb shape, the surface area of the adsorbing portion and the desorbing portion of the adsorbent 50 is widened. Thereby, moisture can be adsorbed efficiently by taking a wide area in contact with the passing air.

  In the outdoor controller 27, a time from when the outdoor fan 33 starts to be adsorbed to the adsorbent 50 to some extent is set. Each time this set time elapses, the outdoor controller 27 operates the rotary motor 36 to rotate the adsorbent 50 approximately 180 degrees.

  For this reason, even if a humidification operation is performed in a state where moisture is not adsorbed on the adsorbent 50 (here, a humidification operation instruction immediately after the start of the heating operation), the humidification operation is not performed. From this, as described above, after the humidifying operation instruction is received by the outdoor controller 27, the elapsed time after the outdoor fan 33 is driven is determined. For example, it is assumed that the time for adsorbing moisture to the adsorbent 50 to some extent is set to 15 minutes. Thus, when the humidifying operation instruction is received by the outdoor controller 27, if the driving time of the outdoor fan 33 has passed 15 minutes, the adsorbent 50 is rotated by approximately 180 ° by the rotary motor 36. When the adsorbent 50 rotates approximately 180 °, the desorption fan 48 provided in the desorption ventilation path 52 is activated. By operating the desorption fan 48, an air flow T is generated in the desorption ventilation path 52, and this air flow T passes through the high-temperature heat exchanger 24 and the heat sink 28 in order, and thereby the heated air and Become. This heated air passes through the desorption part of the adsorbent 50 containing moisture, thereby desorbing moisture. By including the desorbed moisture, the heated air becomes humid air with high humidity. The humidified air is sent to the tube duct 18 by the desorption fan 48 and is blown to the indoor unit 100 via the tube duct 18.

  As described above, desorption and adsorption are continuously performed since desorption and adsorption of the adsorbent 50 are exchanged (rotated) every 15 minutes by the rotation motor 36. . That is, the humidifying operation is continuously performed.

  As described above, according to the air conditioner 1 </ b> A according to the second embodiment, the adsorbent 50 provided in the outdoor unit 200 </ b> A is provided with the rotation shaft 37 on the vertical partition plate 49 and further straddles the vertical partition plate 49. By arranging, the adsorption ventilation path S is provided in the heat exchanger chamber 31. For this reason, only the outdoor fan 33 is driven, and it is not particularly necessary to provide a component for providing the suction ventilation path S or a suction fan. For this reason, it is possible to reduce the cost by reducing the number of components.

  Further, since the adsorbing body 50 is disposed across the vertical partition plate 49, the degree of freedom for installation of the adsorbing body 50 is increased. For this reason, the volume concerning the installation of the adsorbent 50 is reduced, and the outdoor unit 200A can be downsized. Moreover, you may improve a humidification capability by enlarging the adsorbent body 50. FIG.

  Furthermore, since the adsorbent 50 is rotated by about 180 ° about the rotation shaft 37 every predetermined time by the rotation motor 36, the adsorbent 50 can be continuously adsorbed and desorbed, thereby improving the humidification efficiency. it can.

  In addition, since the adsorbent 50 has a honeycomb shape, a wide surface area for adsorption and desorption can be obtained. Thereby, the efficiency of adsorption and desorption can be improved.

  FIG. 6 is an explanatory view schematically showing the outdoor unit 200B used in the air conditioner 1B according to the third embodiment of the present invention from the side, and FIG. 7 is an explanatory view schematically showing the upper side of the outdoor unit 200B. It is. 6 and 7, the same functional parts as those in FIGS. 1 to 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

  The outdoor unit 200B used in the air conditioner 1B according to the third embodiment is provided in the horizontal partition plate 56 and is connected to the desorption ventilation path 57 so as to suck in the air above the compressor 11. A port 58 and a desorption suction port filter 59 provided in the desorption air passage suction port 58 are provided.

  In the air conditioner 1 </ b> B configured as described above, the desorption fan 48 is operated to suck the air heated by the compressor 11 above the compressor 11 from the desorption air passage suction port 58. Further, the heated air sucked from the desorption air passage suction port 58 is further heated by sequentially passing through the high temperature heat exchanger 24 and the heat sink 28. This heated air passes through the desorption part of the adsorbent 50 containing moisture, thereby desorbing moisture. By including the desorbed moisture, the heated air becomes humidified air.

  As described above, according to the air conditioner 1B according to the third embodiment, the heated air heated by the compressor 11 above the compressor 11 is provided with the desorption air passage suction port 58 in the horizontal partition plate 56. Then, the air can be further heated by sequentially passing through the high-temperature heat exchanger 24 and the heat sink 28. Thereby, the efficiency of desorption can be improved. Furthermore, since the air above the compressor 11 is sucked, the heating capacity of the high-temperature heat exchanger 24 may be small, and the high-temperature heat exchanger 24 can be downsized. Thereby, the outdoor unit 200B can also be reduced in size.

  FIG. 8 is a perspective view schematically showing an inverter device 26A and a heat sink 28A used in an air conditioner according to a fourth embodiment of the present invention, and FIG. 9 is a block diagram schematically showing the inverter device 26A. 10 is a flowchart showing operation control of the air conditioner. 8 to 10, the same functional parts as those in FIGS. 1 to 7 are denoted by the same reference numerals, and detailed description thereof is omitted.

  The air conditioner according to the fourth embodiment differs from the first embodiment in the structure of the part of the desorption air passage 60, the configuration of the inverter device, and the control of the inverter device. The outdoor unit is connected to the compressor 11 and a brushless DC motor 62 of the compressor 11 to be described later as shown in FIG. And a heat sink 28A for dissipating the heat of the inverter device 26A.

  As shown in FIG. 9, the compressor 11 includes a brushless DC motor (hereinafter “DC motor”) 62 used as a compressor motor, for example. The DC motor 62 includes a stator having three phase windings Lu, Lv, and Lw that are star-connected around a neutral point C, and a rotor having a permanent magnet.

  The inverter device 26A is a switching device that receives the DC voltage Vd between the input terminals P and N to which the DC voltage Vd is applied and receives the DC voltage Vd between the input terminals P and N and switches the energization to the phase windings Lu, Lv, and Lw. A circuit 63, a control unit 64 for controlling the operation of the switching circuit 63, a rectifier circuit 66 for rectifying the AC voltage of the commercial AC power supply 65, and smoothing the output voltage (DC voltage) of the rectifier circuit 66 to input the input terminals P, N A smoothing capacitor 67 applied between them and a power supply circuit 68 are provided. The power supply circuit 68 generates a DC voltage V1 for operating the switching circuit 63 from an AC voltage of the commercial AC power supply 65, and generates a DC voltage V2 for operating the control unit 64 and the switching circuit 63. Output.

  The switching circuit 63 includes a series circuit of switching elements on the upstream side, for example, an IGBT (Insulated Gate Bipolar Transistor), and switching elements on the downstream side, for example, a low-loss power MOSFET, along the application direction of the DC voltage Vd. It has three phases. An IGBT 3u is provided on the upstream side of the U phase, and a MOSFET 4u is provided on the downstream side. An IGBT 3v is provided on the upstream side of the V phase, and a MOSFET 4v is provided on the downstream side. An IGBT 3w is provided on the upstream side of the W phase, and a MOSFET 4w is provided on the downstream side. Then, free-wheeling diodes (rectifier elements) Du +, Dv +, Dw + are connected in reverse parallel to the IGBTs 3u, 3v, 3w, respectively. The free-wheeling diodes Du +, Dv +, and Dw + are connected in reverse parallel to the MOSFETs 4u, 4v, and 4w, respectively.

  An interconnection point between the IGBT 3u and the MOSFET 4u is formed at the output terminal Qu, an interconnection point between the IGBT 3v and the MOSFET 4v is formed at the output terminal Qv, and an interconnection point between the IGBT 3w and the MOSFET 4w is formed at the output terminal Qw. The non-connection end of the phase winding Lu is connected to the output terminal Qu, the non-connection end of the phase winding Lv is connected to the output terminal Qv, and the non-connection end of the phase winding Lw is connected to the output terminal Qw. It is connected.

  Further, the switching circuit 63 is connected to the upstream when the forward current (return current) flows through the free-wheeling diodes Du−, Dv−, and Dw− by the energy stored in the phase windings Lu, Lv, and Lw that are inductive loads. The reverse current flowing in the freewheeling diodes Du−, Dv−, and Dw− when the IGBTs 3u, 3v, and 3w on the side are turned on is suppressed. For this reason, reverse voltage application circuits 5u, 5v, 5w for applying reverse voltages to the free-wheeling diodes Du-, Dv-, Dw- prior to turning on the IGBTs 3u, 3v, 3w are provided.

  Further, the heat sink 28A described above is on the desorption ventilation path 60, and the back surfaces of the MOSFETs 4u, 4v, 4w, IGBTs 3u, 3v, 3w, and the reflux diodes Du +, Dv +, Dw +, Du−, Dv−, Dw−. It is arranged at the location located at. Furthermore, the heat sink 28A is formed, for example, by extruding and integrally forming an Al material.

  According to the air conditioner configured as described above, the reverse voltage application circuit 5u, the reverse voltage application circuit 5u, to the return diodes Du−, Dv−, and Dw−, before the switching elements of the IGBTs 3u, 3v, and 3w provided in the inverter device 26A are turned on. By applying reverse voltages from 5v and 5w, reverse currents flowing through the freewheeling diodes Du−, Dv−, and Dw− can be suppressed. Thereby, the power loss in IGBT which is a switching element can be reduced significantly, and efficiency can be improved.

  Almost all of the loss of the switching element generates heat. Therefore, the reverse voltage application circuits 5u, 5v, and 5w are activated to suppress the heat dissipation of the IGBT. On the other hand, in order to improve the humidifying efficiency during the humidifying operation, the temperature of the heated air blown to the desorption part of the adsorbent 50 needs to be high. For this reason, the reverse voltage application circuits 5u, 5v, and 5w are not operated during the humidifying operation. Thereby, heat loss of the heat sink increases by intentionally increasing the loss in the switching element. By these things, the temperature of heated air can be made high. Thereby, humidification efficiency can be improved.

  As described above, the normal humidification operation is performed during the heating operation. For this reason, the humidified air that has passed through the adsorbent 50 passes through the tube duct 18 and is blown into the room, and heat generated by the loss in the switching element is supplied into the room. This also contributes to the indoor heating operation, and the loss generated by the switching element is efficiently used for the heating operation as a result.

Next, the operation control of the air conditioner will be described using the flowchart of FIG.
First, for example, during a heating operation, when the user instructs the indoor unit 100 to perform a humidifying operation using the remote controller 23, the indoor controller 22 of the indoor unit 100 receives the humidifying operation instruction signal R. This instruction signal R is transmitted from the indoor controller 22 to the outdoor controller 27 (ST1, YES).

  When receiving the humidifying operation instruction signal R, the outdoor controller 27 performs control to stop the operation of the reverse voltage application circuits 5u, 5v, 5w for the MOSFETs 4u, 4v, 4w (ST2). By this reverse voltage application circuit 5u, 5v, 5w stop control, the loss in the switching element of the inverter device 26A increases, and the temperature of the heat sink 28A rises.

  Subsequently, the outdoor controller 27 determines whether or not the discharge temperature Td of the compressor 11 detected by the discharge temperature sensor 25 is dissipating sufficient heat to desorb moisture from the adsorbent 50. The temperature is compared with the set temperature Tds set in the device 27. If Td is larger than Tds (ST3, YES), the outdoor controller 27 drives the desorption fan 48 and the outdoor fan 33, which is an adsorption fan (ST4).

  When the desorption fan 48 and the adsorption fan 45 are operated, the adsorbent 50 adsorbs moisture from the outdoor air and desorbs moisture in the desorption air passage 60. Here, the outdoor controller 27 rotates the rotation motor 36 by a predetermined angle for a predetermined time so that the adsorbent 50 can continuously adsorb and desorb (ST5).

  When the discharge temperature Td is lower than the set temperature Tds (ST3, NO), the outdoor controller 27 detects the temperature Ti of the heat sink 28A from the heat sink temperature sensor 29. The outdoor controller 27 compares the set temperature Tis and Ti of the heat sink 28 sufficient to desorb the moisture of the adsorbent 50 set in the outdoor controller 27. When Ti is larger than Tis (ST6, YES), the suction fan 45 and the desorption fan 48 are operated (ST4), and the above-described ST5 is performed.

  When the temperature Ti of the heat sink 28A is smaller than the set temperature Tis (ST6, NO), the suction fan 45 is operated while the desorption fan 48 is stopped (ST7).

  When the humidifying operation instruction signal R is not transmitted from the remote controller 23 to the indoor controller 22 of the indoor unit 100 (ST1, NO), since the humidifying operation is OFF, the desorption fan 48 and the suction fan (outdoor fan 33) are turned off. ) Is stopped (ST8). At this time, in order to reduce the loss of the inverter device 26A without performing the humidifying operation, the reverse voltage application circuits 5u, 5v, and 5w are operated (ST9) as the high-efficiency operation of the inverter device 26A. As a result, the temperature of the heat sink 28A is kept low. The rotary motor 36 is also stopped.

  Next, when the remote control 23 sends a humidification operation end or normal operation instruction signal R to the indoor controller 22 of the indoor unit 100, the outdoor controller 27 terminates the humidification operation and the normal operation. Or, the operation stop of the air conditioner is controlled (ST10).

  As described above, according to the air conditioner according to the fourth embodiment, the operation of the reverse voltage application circuits 5u, 5v, and 5w is stopped during the humidifying operation, so that the switching element of the inverter device 26A can be used during the humidifying operation. Is increased, and the temperature rise of the heat sink 28A is increased. As a result, the temperature of the heat sink 28A rises in an early time from the start of the humidification operation. Furthermore, since the heat sink 28A becomes high temperature during operation, it facilitates desorption of the adsorbent 50. Thereby, it can be set as the improvement of humidification efficiency. Further, the loss of the switching element can increase not only the desorption of moisture from the adsorbent 50 but also the heat together with the humidified air in the room, so that the heating capacity can be increased.

  FIG. 11 is an explanatory diagram schematically showing an outdoor unit 200D used in an air conditioner 1D according to a fifth embodiment of the present invention from the side, and FIG. 12 is an explanatory diagram schematically showing the top of the outdoor unit 200D. FIG. 13 is an explanatory view schematically showing the compressor 11 and the high-temperature heat exchanger 24 used in the outdoor unit 200D, and FIG. 14 is an explanatory view schematically showing an example of the use of the outdoor unit 200D from above. FIG. 15 is a flowchart showing operation control of the air conditioner 1D. 11 to 15 that are the same as those in FIGS. 1 to 10 are assigned the same reference numerals, and detailed descriptions thereof are omitted. In FIG. 14, U indicates the air flow to the heat sink. The inverter device of the air conditioner according to the fifth embodiment is the same as the inverter device 26A of the fourth embodiment shown in FIG. 9, and the indoor unit is the same as that of the first embodiment shown in FIG. It is the same as the indoor unit 100 of the form.

  An air conditioner 1D according to the fifth embodiment includes an outdoor unit 200D. The outdoor unit 200D is provided with an inverter device 26A, a vertical partition plate 69 that vertically partitions the interior of the outdoor unit 200D, and a cylindrical suction member that is provided across the vertical partition plate 69, and the rotation shaft 37 is provided substantially vertically. And a body 70. The outdoor unit 200 </ b> D is partitioned into a heat exchanger chamber 31 and a compressor chamber 32 by a vertical partition plate 69.

  The adsorbent 70 has a substantially cylindrical center, a partition plate 71 that includes the rotation shaft 37 and bisects in the vertical direction, and a plurality of the adsorbers 70 that are arranged in parallel to the partition plate 71 and capable of adsorbing and desorbing moisture. The suction plate 72, the partition plate 71, and the rotating shaft 37 provided substantially at the center of the cylindrical shape are provided. Further, a rotation motor 36 that is connected to the rotation shaft 37 and rotates the adsorbent 70 is provided.

  The heat exchanger chamber 31 includes an outdoor heat exchanger 15, an adsorbing portion of the adsorbing body 70, an outdoor fan 33 for allowing the adsorbing portion of the adsorbing body 70 and the outdoor heat exchanger 15 to ventilate, and the outdoor fan 33. And a fan motor 34 for rotating the motor. In addition, the heat exchanger chamber 31 is divided into two parts by a ventilation path F that ventilates from outside to the outside through the outdoor heat exchanger 15 and the outdoor fan 33, and a partition plate 71 of the adsorbent 70. The adsorption | suction ventilation path S provided so that the outdoor air containing including may pass (ventilate) is formed. Further, an adsorbent filter 73 is provided so as to prevent dust from entering the adsorbent 70 by covering a portion of the adsorbent 70 located in the heat exchanger chamber 31.

  The compressor chamber 32 includes a horizontal partition plate 35 that partitions horizontally, and the compressor chamber 32 is vertically divided by the horizontal partition plate 35. Below the compressor chamber 32, the compressor 11, the four-way valve 12, the pressure reducing valve 14, and the accumulator 16 are arranged.

  At the upper part of the compressor chamber 32, a desorption part for the adsorbent 70 rotated by the rotary motor 36 is provided. The adsorbent 70 moves to the position of the desorption part by rotating the adsorption part that adsorbs moisture by allowing air to pass therethrough, and the heated air is heated to a high temperature at the part adsorbing the moisture. It is formed so that moisture adsorbed by passing it is desorbed by the desorbing part. The adsorbent 70 is formed to be able to switch between the adsorbing part and the desorbing part at regular intervals by being rotated approximately 180 ° by the rotary motor 36.

  In the upper part of the compressor chamber 32, a desorption air passage 74 provided so that heated air for desorbing moisture passes through (approximately vents) approximately half of the surface area of the adsorbent 70 is an air passage partition frame. 75.

  The desorption ventilation path 74 has a desorption ventilation path suction port 76 for sucking outdoor air, and a desorption ventilation path formed in the desorption ventilation path 74 so as to prevent dust from entering the desorption ventilation path 74. The filter 77, the high-temperature heat exchanger 24 that is heated by passing the air that has passed through the desorption air passage filter 77, and the inverter device 26A that is cooled by the air that has passed through the high-temperature heat exchanger 24 Heat sink 28A, the desorption part of the adsorbent 70 through which heated air heated by the heat sink 28A passes, and the air that has passed through the desorption part of the adsorbent 70 are blown to the indoor unit 100 through the tube duct 18. The desorption fans 48 are sequentially arranged. By operating the desorption fan 48, an air flow S is generated in the suction ventilation path 74.

  As shown in FIG. 13, the compressor 11 and the high-temperature heat exchanger 24 are connected by a refrigerant pipe 17, and the refrigerant discharged from the compressor 11 is placed on the refrigerant pipe 17 on the high-temperature heat exchanger 24. On-off valves 78a and 78b are provided for opening and closing the refrigerant pipe 17 so that the refrigerant pipe 17 does not flow.

  In the air conditioner 1D configured as described above, when the humidifying operation is performed, first, when the outdoor controller 27 receives an instruction of the humidifying operation, the outdoor controller 27 determines an elapsed time after the outdoor fan 33 is driven. to decide.

  Since the adsorbing part of the adsorbent 70 is disposed in the heat exchanger chamber 31, outdoor air is passed through the ventilation path F and the adsorption ventilation path S when the outdoor fan 33 is driven. At this time, the outdoor air passing through the suction ventilation path S passes through the adsorption portion between the partition plate 71 of the adsorption body 70 and the plurality of adsorption plates 72 via the adsorption body filter 73. The outdoor air ventilates the inside of the slit-shaped adsorbent 70 provided in the adsorbing portion, so that moisture contained in the air is adsorbed to the adsorbent 70. The adsorbent 70 has a slit shape, and from this shape, air resistance is low with respect to the passing air, and air can flow.

  The outdoor controller 27 is set with a time during which moisture is adsorbed to the adsorbent 70 to some extent after the outdoor fan 33 is driven. Each time this set time elapses, the outdoor controller 27 operates the rotation motor 36 to rotate the adsorbent 70 approximately 180 degrees.

  After the humidifying operation instruction is received by the outdoor controller 27, the elapsed time after the outdoor fan 33 is driven is determined. For example, it is assumed that the time for which moisture is adsorbed to the adsorbent 70 is set to 15 minutes. As described above, when the outdoor controller 27 receives the humidifying operation instruction and the driving time of the outdoor fan 33 has passed 15 minutes, the rotating body 36 rotates the adsorbent 70 by approximately 180 °. When the adsorbent 70 rotates approximately 180 °, the desorption fan 48 provided in the desorption ventilation path 74 is activated. When the desorption fan 48 is operated, an air flow T is generated in the desorption ventilation path 74, and this air flow T sequentially passes through the high-temperature heat exchanger 24 and the heat sink 28A, so that heated air and Become. The heated air passes through the desorption part of the adsorbent 70 containing moisture, thereby desorbing moisture. By including the desorbed moisture, the heated air becomes humidified air. The humidified air is sent to the tube duct 18 by the desorption fan 48 and is blown to the indoor unit 100 via the tube duct 18.

  As described above, desorption and adsorption are continuously performed since the desorption part and the adsorption part of the adsorbent 70 are exchanged (rotated) every 15 minutes by the rotary motor 36. That is, the humidifying operation is continuously performed.

  During the humidification operation described above, an air flow T is generated in the desorption air passage 74, whereby the air is heated. For this reason, since the heat sink 28A of the inverter device 26A is disposed on the separation ventilation path 74, the heat sink 28A is forcibly cooled. However, if the humidification operation is not performed and the cooling or heating operation is performed, the desorption fan 48 is deactivated, and the air flow T is not generated in the desorption air passage 74.

  Thus, if no air flow occurs in the desorption air passage 74, the heat sink 28A is not cooled, and the temperature of the inverter device rises abnormally. To prevent this, when the humidification operation is stopped, the outdoor controller 27 operates the rotary motor 36 so that the adsorbent 70 is positioned so that the direction of the partition plate 71 is substantially perpendicular to the vertical partition plate 69. Rotate only degrees. By rotating the adsorbent 70 in this way, as shown in FIG. 14, the desorption flow passage 74 in which the heat exchanger chamber 31 and the heat sink 28 </ b> A are arranged is slit between the plurality of adsorbing plates 72 of the adsorbent 70. It will be communicated via. As a result, an air flow U is generated from the side of the desorption flow passage 74 where the heat sink 28A is provided to the heat exchanger chamber 31 by the operation of the outdoor fan 33 that operates substantially in conjunction with the operation of the inverter device 26A. .

  The heat sink 28A can be cooled by the air flow U. Further, at this time, a refrigerant flow path as shown in FIG. 13 is formed, the on-off valve 78a is closed, and the on-off valve 78b is opened, whereby the refrigerant discharged from the compressor 11 is bypassed to the on-off valve 78b side, and high temperature heat is generated. Prevent high temperature refrigerant from flowing through the exchanger 24. Thereby, the heat sink 28A can be efficiently cooled. In the cooling operation, the cooling capacity increases when the refrigerant flows through the high-temperature heat exchanger 24. For this reason, during the cooling operation, control may be performed so that the on-off valve 78a is opened and the on-off valve 78b is closed so that the refrigerant flows into the high-temperature heat exchanger 24.

Next, the operation control of the air conditioner 1D will be described using the flowchart shown in FIG.
First, for example, during a heating operation, when the user instructs the indoor unit 100 to perform a humidifying operation using the remote controller 23, the indoor controller 22 of the indoor unit 100 receives the humidifying operation instruction signal R. This instruction signal R is transmitted from the indoor controller 22 to the outdoor controller 27 (ST20, YES).

  When receiving the humidifying operation instruction signal R, the outdoor controller 27 performs control to stop the operation of the reverse voltage application circuits 5u, 5v, 5w for the MOSFETs 4u, 4v, 4w (ST21). By this reverse voltage application circuit 5u, 5v, 5w stop control, the loss in the switching element of the inverter device 26A increases, and the temperature of the heat sink 28A rises.

  Subsequently, the outdoor controller 27 determines whether or not the discharge temperature Td of the compressor 11 detected by the discharge temperature sensor 25 is dissipating sufficient heat to desorb moisture from the adsorbent 70. The temperature is compared with the set temperature Tds set in the device 27. If Td is greater than Tds (ST22, YES), the outdoor controller 27 drives the desorption fan 48 and the outdoor fan 33 (suction fan) (ST23).

  When the desorption fan 48 and the outdoor fan 33 are driven, the adsorbent 70 adsorbs moisture from the outdoor air and desorbs moisture through the desorption air passage 74. Here, the outdoor controller 27 rotates the rotary motor 36 by approximately 180 ° every predetermined time so that the adsorbent 70 can continuously adsorb and desorb. At the same time, the outdoor controller 27 causes the high-temperature refrigerant to flow through the high-temperature heat exchanger 24 by opening the on-off valve 78 (ST24).

  When the discharge temperature Td is lower than the set temperature Tds (ST22, NO), the outdoor controller 27 detects the temperature Ti of the heat sink 28A from the heat sink temperature sensor 29. The outdoor controller 27 compares the set temperature Tis and Ti of the heat sink 28A sufficient to desorb the moisture of the adsorbent set in the outdoor controller 27. When Ti is larger than Tis (ST25, YES), the outdoor fan 33 and the desorption fan 48 are operated (ST23), and ST24 described above is performed.

  When the temperature Ti of the heat sink 28A is smaller than the set temperature Tis (ST25, NO), the outdoor fan 33 is operated while the desorption fan 48 is stopped (ST26).

  When the remote control 23 does not transmit the humidifying operation instruction signal R to the indoor controller 22 of the indoor unit 100 (ST20, NO), the outdoor controller 27 causes the rotary motor 36 to move the partition plate 71 of the adsorbent 70 vertically. The adsorbent 70 is rotated so as to be substantially perpendicular to the partition plate 69 (approximately 90 °). At the same time, the outdoor controller 27 closes the on-off valve 78a and opens the on-off valve 78b to stop the refrigerant from flowing into the high-temperature heat exchanger 27 (ST27).

  Since the humidification operation is OFF, the desorption fan 48 remains stopped (ST28). However, since the adsorption fan is also used as the outdoor fan 33 for the refrigeration cycle, as long as the refrigeration cycle is operating ( Continue operation (except in special situations such as during defrosting). At this time, in order to reduce the loss of the inverter device 26A in a state where the humidifying operation is not performed, the reverse voltage application circuits 5u, 5v, and 5w are operated (or permitted to operate when necessary) as a highly efficient operation of the inverter device 26A ( ST29). Thereby, the temperature of the heat sink 28A is maintained in a low state. In addition, the heat sink 28A is favorably cooled by the air flow U flowing to the heat exchanger chamber side through the slits of the adsorbent 70. The operation of the rotary motor 36 is also stopped.

  After completing any of the steps ST24, ST26 and ST29 relating to the humidifying operation, the normal operation or the operation stop control of the air conditioner is performed (ST30). Thus, the control of the outdoor controller 27 is finished.

  As described above, according to the air conditioner 1D according to the fifth embodiment, the operation of the reverse voltage application circuits 5u, 5v, 5w is stopped during the humidifying operation, and the switching element of the inverter device 26A is used during the humidifying operation. The loss is increased and the temperature rise of the heat sink 28A is increased. Thereby, the temperature of the heat sink 28A rises in a short time from the start of the humidifying operation. Furthermore, since the heat sink 28A becomes high temperature during operation, it promotes desorption of the adsorbent 70. Thereby, humidification efficiency can be improved.

  In addition, the loss of the switching element can increase not only the moisture desorption of the adsorbent 70 but also the heat with the humidified air in the room, so that the heating capacity can be increased.

  Further, when the humidification operation is stopped, the adsorbent 70 is rotated by approximately 90 ° with respect to the vertical partition plate 69 by the partition plate 71, so that outdoor air can be blown to the heat sink 28A by the operation of the outdoor fan 33. The heat sink 28A can be satisfactorily cooled during operation of the conditioner. In addition, when the humidification operation is stopped, the efficiency can be improved by stopping the flow of the high-temperature refrigerant to the high-temperature heat exchanger 24 using the on-off valves 78a and 79b.

  Here, the refrigerant piping circuit of the compressor 11 and the high-temperature heat exchanger 24 may be configured as shown in FIG. In this case, the opening / closing control of the on-off valve 78 may be controlled to be closed when the refrigerant flows through the high temperature heat exchanger 24 and to be opened when the refrigerant does not flow through the high temperature heat exchanger 24.

  In addition, by making the direction of the rotation shaft 37 of the adsorbent body 70 a vertical (vertical) direction, the adsorbent body 70 can be shaped to be long in the axial direction. Further, by setting the ventilation direction for adsorption / desorption to a direction perpendicular to the rotation shaft 37, the degree of freedom of arrangement of the components is increased.

  The present invention is not limited to the above embodiment. For example, in the above-described example, the outdoor air is used for desorption by providing the desorption ventilation path suction port 76 of the desorption ventilation path 74 of the air conditioner 1D in the wall portion of the outdoor unit 200D. 18, a desorption air passage inlet 79 and a desorption air passage filter 80 may be provided so that the air above the compressor 11 is used for desorption. By setting it as such a structure, the temperature of the heating air used for desorption can be made higher temperature. A humidification effect can be improved more by making heated air into high temperature.

  Further, the adsorbent 70 of the air conditioner 1D is configured to have the adsorbing plate 72 substantially parallel to the partition plate 71. However, as shown in FIG. is there. By setting it as such a structure, it becomes possible to enlarge an adsorption area further and can improve adsorption | suction efficiency. In addition, you may provide the crosspiece 81 in a part. By using the horizontal rail 81 as a part, the blowing resistance can be lowered. Further, the adsorbent can cope with any shape as long as it has a low air resistance with respect to the air to be blown and can obtain a surface area for performing as much adsorption / desorption as possible.

  Furthermore, the configuration of the inverter device 26A described above may not be the configuration described above. For example, all the switching elements may be MOSFETs, or some of them may be MOSFETs. In addition, various modifications can be made without departing from the scope of the present invention.
