Description

  The present invention relates to an air conditioning system that efficiently harmonizes indoor air. More specifically, the present invention relates to an air conditioning system that can deliver conditioned air generated by an indoor unit to an arbitrary place in a room.

  As the air conditioner, a wall-mounted type installed on a wall surface, a ceiling-suspended type used by hanging from a ceiling, and a ceiling-embedded type embedded in the ceiling are well known. For general households, the wall-mounted type is the mainstream, and usually one unit is arranged for one room. Two or more units may be installed depending on the size of the room.

  Normally, a single air conditioner for home use is responsible for the air conditioning of all rooms. However, in a room where large furniture such as kitchens and living dining rooms are scattered, the furniture interferes with the air flow. It tends to cause temperature unevenness. In particular, in LDK type condominiums, the kitchen space is often partitioned from the living and dining space, making it difficult to air-condition the kitchen space.

  Thus, for example, in Patent Document 1, a circulator that is driven in conjunction with an indoor unit of an air conditioner is provided, and the air sent from the indoor unit is forced to circulate by the circulator to suppress the occurrence of temperature unevenness. ing.

  However, the air conditioning system described in Patent Document 1 has the following problems. That is, the air conditioning system described in Patent Document 1 is intended only for indoor air circulation, and cannot directly blow air against temperature unevenness generated in a space partitioned by furniture or walls. Moreover, it aimed at circulation within the ventilation range of an indoor unit, and could not send out air to the temperature nonuniformity outside the ventilation range of the indoor unit.

  On the contrary, the sensible temperature differs depending on men and women, and even the physical condition, etc., but the air conditioning system described in Patent Document 1 is intended for circulation (stirring) for uniform room temperature. It is not possible to send cold air or hot air in a spot according to the temperature. Moreover, since the circulator is fixed to the wall surface, the installation location cannot be freely moved according to the season.

Next, the operation | movement based on the various steps of the air conditioning system which concerns on 1st-6th embodiment of this invention is demonstrated using FIGS. In addition, the air conditioner unit 2 of the present invention is a cooling / heating operation by the same refrigeration cycle system as a general air conditioner, and a detailed description of its operation is omitted. In addition, it is assumed that the infrared signal transmission / reception among the air conditioner unit 2, the MF unit 3 and the remote controller 4 can be performed bidirectionally via a predetermined communication method.

With reference to FIG. 3, the flow of the process which controls the air conditioning system which concerns on 1st Embodiment is demonstrated. Hereinafter, ST indicates a process step, a number after ST indicates a step number, -Y indicates Yes, and -N indicates No. The process flow for controlling the air conditioning system according to the first embodiment, first, by operating the operation unit 44 of the remote controller 4, with turn of the air conditioner unit 2 (ST 101), MF unit 3 and the air-conditioning The MF mode for interlocking with the machine unit 2 is turned on (ST102).

After performing the MF position detection process A, if the wind direction plate of the MF unit 3 confirms whether not suitable to the air conditioner unit 2 (ST120), faces the air conditioner unit 2 (ST120-N) is , if the wind direction of the MF unit 3 is a wind-direction correction signal to MF unit 3 so as not suitable towards the air conditioner unit 2 sends (ST121), is not suitable (ST120-Y), the processing proceeds to ST122. Then, towards the wind direction of the air conditioner unit 2 to MF unit 3 (ST122), it starts blowing direction from the air conditioner unit 2 to MF unit 3 (ST123).

  Here, the MF position detection processing A will be described with reference to FIG. The control unit 7 confirms turning on the power to the MF unit 3 (ST103), and if the power is not turned on (ST103-N), the control unit 7 transmits an ON signal to turn on the power to the MF unit 3 (ST104). ). If the power is on (ST103-Y), the process proceeds to ST108.

Then, to confirm whether the power of the MF unit 3 is ON (ST105), when the result is not as ON (ST105-N) displays a message indicating a communication error (ST 106), the air conditioner unit 2 alone Operation is performed (ST112). Here, the control unit 7 turns on the power of the MF unit 3, but the power of the MF unit 3 may be turned on directly by the remote controller 4.

In the case the power supply of the MF unit 3 is ON (ST103-Y), confirm whether the operation mode of the MF unit 3 and the air conditioner unit 2 are the same (ST 108), when the operation mode is the same In (ST108-Y), the process proceeds to ST110, and when different (ST108-N), an operation mode signal is transmitted to the MF unit 3 (ST109). Thereafter, the position detection of the MF unit 3 (ST110), if unable to position detection (ST110-N), a warning to the effect that can not be detected (ST111), the air conditioner unit 2 performs independent operation (ST 112 ).

  If the position of the MF unit 3 can be detected (ST110-Y), the MF position detection process A is terminated.

  Next, the operation of the MF unit 3 will be described. When an MF mode button (not shown) provided on the operation unit 44 of the remote controller 4 is operated, the control unit 7 starts an MF mode program stored in the memory 72 and transmits an ON signal to the MF unit 3. The MF unit 3 receives the signal (ST201).

  After performing the MF position detection process B, the MF unit 3 confirms whether or not a wind direction correction signal has been received (ST220), and if a correction signal has been received (ST220-Y), corrects the wind direction (ST221). ), When the correction signal is not received (ST220-N), the process proceeds to ST222 and the operation is performed according to the mode.

Here, the MF position detection process B will be described with reference to FIG. When the power is ON (ST202-Y), the MF unit proceeds to ST204, and when the power is not ON (ST202-N), the MF unit is turned on (ST203) and proceeds to ST204.

  Thereafter, a mode signal is received from the control unit 7 (ST204), and the operation mode of the MF unit 3 is changed (ST205). Then, the MF unit 3 transmits an infrared signal having a specific wavelength as position information by blinking the infrared transmitter 37 at a predetermined interval (ST206). The acquisition of the position information may be executed by the indoor unit 5 by the image recognition device.

  Next, the MF unit 3 checks the current state of the outlet of the MF unit 3 and the wind direction plate 32, receives the request for the wind direction information from the control unit 7, and transmits the wind direction information to the control unit 7 (ST207). ), And ends the MF position detection process B.

  In the first embodiment, the case of one MF unit 3 has been described as an example. However, for example, two or more MF units 3 are installed in a room, and air sent from the indoor unit 5 is converted into a plurality of MF units 3. You may make it circulate through a room, relaying by the unit 3. FIG.

  According to the control method described in FIG. 3, air is blown from the indoor unit 5 to the MF unit 3, and the air is relayed by the MF unit 3, so that the temperature of the room is adjusted more efficiently than the indoor unit 5 alone. Energy saving and environmentally friendly.

  Next, with reference to FIG. 4 a, b, operation | movement of the temperature nonuniformity elimination mode of the air conditioning system which concerns on 1st Embodiment is demonstrated. This operation mode is for correcting the non-uniformity of the temperature distribution in the room. The indoor unit 5 or the MF unit 3 blows air to a portion having a temperature difference from the surroundings. It is assumed that the air conditioner unit 2, the MF unit 3, and the remote controller 4 have already been turned on and are capable of bidirectional communication.

If temperature unevenness elimination mode is selected by the user, the air conditioner unit 2, the wind after performing MF position detection process A, the temperature unevenness information obtained by the position information and the thermopile MF unit 3, to a temperature unevenness (ST130). When it is determined that it does not reach (ST130-N), the operation is performed in the stirring mode in which the wind direction plate is swung to blow air (ST131). If it is determined that it reaches (ST130-Y), it is confirmed whether or not the wind direction of the MF unit faces the direction of temperature unevenness (ST132). The air direction may be confirmed by providing an image recognition device in the indoor unit 5 and specifying the direction of the air outlet from the shape of the MF unit 3.

  If it is not directed in the direction of temperature unevenness (ST132-N), wind direction correction information is transmitted to the MF unit 3 (ST133), and the process proceeds to ST134. If it is determined that it is facing (ST132-Y), the MF unit 3 is instructed to start air blowing (ST134), temperature unevenness is measured (ST135), and it is confirmed whether the temperature unevenness has been eliminated (ST136). ).

  If the temperature unevenness is not eliminated (ST136-N), the same steps are repeated from ST134. When it is determined that the temperature unevenness has been eliminated (ST136-Y), the MF unit 3 is notified of the end of the mode (ST137), and the process ends.

  When the temperature unevenness elimination mode is selected, after performing the MF position detection process B, the MF unit 3 checks whether or not wind direction correction information has been received (ST230), and determines that no reception has been received (ST230- N), operation according to the mode is started (ST231), and the process proceeds to ST233. When it is determined that there is reception (ST230-Y), the wind direction is corrected (ST232), and the process proceeds to ST233.

  Next, it is confirmed whether or not the mode end information has been received (ST233). If it is determined that there is no reception (ST233-N), the above series of steps are repeated until reception information is obtained. If it is determined that there is reception (ST233-Y), the process ends.

  Next, with reference to FIG. 5a, b, operation | movement of the noise reduction mode of the air conditioning system which concerns on 2nd Embodiment of this invention is demonstrated. This operation mode is for reducing the blowing noise of the indoor unit 5 or the MF unit 3, and when there is a person near the indoor unit 5 or the MF unit 3, the rotational speed of the blowing fan is lowered. . When the noise reduction mode is selected, after performing the MF position detection process A, it is determined by the human detection sensor 50 whether or not there is a person near the indoor unit 5 (ST141).

  When it is determined that there is a person nearby (ST141-Y), the rotational speed of the blower fan of the indoor unit 5 is decreased (ST142), and the process proceeds to ST146. If it is determined that there is no person (ST141-N), it is determined whether there is a person near the MF unit 3 (ST143), and if there is a person near the MF unit 3, the number of fan rotations to the MF unit 3 is determined. Information is transmitted (ST144), and when it is not near, air-conditioning independent operation is performed (ST145).

  Next, it is confirmed whether or not there has been a mode end instruction (ST146). When there is no instruction (ST146-N), the above series of steps is repeated from the beginning. When there is an instruction (ST146-Y), the MF unit 3 is notified of the end of the mode (ST147), and the process ends.

  After performing the MF position detection process B, the MF unit 3 side confirms whether the blower fan rotational speed information has been received (ST240), and if received (ST240-Y), corrects the rotational speed (ST241). ) Go to ST243. If there is no reception (ST240-N), the rotational speed of the blower fan is maintained (ST242), and the process proceeds to ST243.

  Next, it is confirmed whether mode end information has been received (ST243). If not received (ST243-N), the above steps are repeated from the beginning. If received (ST243-Y), the process ends.

  According to the noise reduction mode, when there is a person near the indoor unit 5 or the MF unit 3, the noise of the indoor unit 5 or the MF unit 3 is reduced by reducing the number of rotations of the blower fan. It is possible to prevent sleep from being disturbed by the blowing sound.

  Next, with reference to FIG. 6 a, b, the Example of the energy saving ventilation mode of the air conditioning system which concerns on 3rd Embodiment of this invention is described. In this operation mode, the rotational speed of the blower fan is adjusted according to the positional relationship between the indoor unit 5 and the MF unit 3. When the indoor unit 5 and the MF unit 3 are close to each other, the blower fan of the indoor unit 5 This is to reduce the rotation speed. When the energy saving blower mode is selected, the air conditioner unit 2 performs the MF position detection process A, and then the position of the MF unit 3 is a weak range in which the wind reaches even if the air volume of the indoor unit 5 is low. Check if it is within the wind range. (ST150).

  When it is determined that the current is within the weak wind range (ST150-Y), after transmitting the range information to the MF unit 3 (ST151), the rotational speed of the blower fan of the indoor unit 5 is decreased (ST152), and the process proceeds to ST154. If it is determined that it is outside the weak wind range (ST150-N), the rotational speed of the blower fan is maintained (ST153), and the process proceeds to ST154.

  Next, it is confirmed whether or not there is a mode end instruction (ST154). If there is no instruction (ST154-N), the above series of steps is repeated from the beginning. If there is an instruction (ST154-Y), the end of the mode is notified to the MF unit 3 (ST155), and the process ends.

  After performing the MF position detection process B, the MF unit 3 confirms whether or not the range information has been received (ST250), and if received (ST250-Y), corrects the rotational speed (ST251) and returns to ST253. move on. If there is no reception (ST250-N), the rotational speed of the blower fan is maintained (ST252), and the process proceeds to ST253.

  Next, it is confirmed whether or not mode end information has been received (ST253). If not received (ST253-N), the above steps are repeated from the beginning. If received (ST253-Y), the process ends.

According to the energy saving air blowing mode, when you move the MF unit 3 within a predetermined range of the indoor unit 5, by a both weak wind blowing the indoor unit 5 and the MF unit 3, wasteful air blowing Energy-saving operation can be performed without performing it.

Next, with reference to FIGS. 7a and 7b, the operation in the swing air blowing mode of the air conditioning system according to the third embodiment of the present invention will be described. This operation mode is to prevent the wind blown from the MF unit 3 from hitting an obstacle. When there is an obstacle in the vicinity of the MF unit 3, the rotational speed of the blower fan is reduced. When the swing air blowing operation mode is selected, the indoor unit 5 performs the MF position detection process A, and then checks whether the MF unit 3 is within the air blowing range where the wind of the indoor unit 5 reaches. (ST160).

If it is determined that the outside air blowing range (ST160-N), to sole operation the air conditioner unit 2 (ST161). When it is determined that it is within the blowing range (ST160-Y), blowing is started toward the MF unit 3 (ST164).

  Next, it is confirmed whether mode end information has been received (ST165). If not received (ST165-N), the above steps are repeated from the beginning. If received (ST165-Y), the MF unit 3 is notified of the end of the swing ventilation mode (ST166), and the process ends.

  When the swing air blowing operation mode is selected, the MF unit 3 performs the MF position detection process B, and then starts the swing operation in which the air outlet is reciprocally operated using the swing motor 36. Thereafter, it is detected whether there is an obstacle nearby using the distance sensor 35 (ST260). If there is an obstacle nearby (ST260-Y), the vehicle is driven by a weak wind (ST262) and proceeds to ST263. If there is no obstacle nearby (ST260-N), the vehicle is driven with strong wind (ST261) and proceeds to ST263.

  Next, it is confirmed whether or not the mode end information has been received (ST263). If it is determined that there is no reception (ST263-N), the above series of steps is repeated until reception information is obtained. If it is determined that there is reception (ST263-Y), the process ends.

  According to the swing ventilation mode shown in FIG. 7, when there is an obstacle near the MF unit 3, the direction of the outlet of the MF unit 3 reciprocates so that the wind does not hit the obstacle at all times. It becomes more efficient by performing a swing operation using the swing motor 36 and blowing air in a direction without an obstacle.

Next, with reference to FIGS. 8 a and b , an example of the operation procedure in the different direction air blowing mode in which the blowing directions of the indoor unit 5 and the MF unit 3 are different from each other will be described. When different direction air blowing mode is selected by the user, the air conditioner unit 2, after performing the MF position detection process A, detects the position of the MF unit 3 by using the thermopile 59 of the indoor unit 5, detects It has been areas to determine areas or far area near the indoor unit 5 (ST170), if it is determined that not close (ST170-N), the air conditioner unit 2 will be isolated operation (ST171).

If it is determined that they are close (ST170-Y), it is determined whether the wind direction of the MF unit 3 is the same as the wind direction of the main body (ST172). If it is determined that they are different (ST172-N), the process proceeds to ST175. When it is determined that the wind directions match (ST172-Y), the wind direction is directed in a direction different from that of the MF unit 3 (ST173).

  Next, it is confirmed whether mode end information has been received (ST175). When not receiving (ST175-N), it repeats from said ST170. If received (ST175-Y), the MF unit 3 is notified of the end of the different direction air blowing mode (ST176), and the process ends.

  After performing the MF position detection process B, the MF unit 3 confirms whether or not the wind direction correction information is received (ST270), and determines that there is no reception (ST270-N), and maintains the wind direction (ST277). Proceed to ST273. When it is determined that there is reception (ST270-Y), the wind direction is corrected (ST271) and the process proceeds to ST273.

  Next, it is confirmed whether or not the mode end information has been received (ST273). If it is determined that there is no reception (ST273-N), a series of steps are repeated until reception information is obtained. If it is determined that there is reception (ST273-Y), the process ends.

  According to this, when the indoor unit 5 and the MF unit 3 are located at positions close to each other, the indoor unit 5 and the MF unit 3 are made different from each other by changing the blowing directions of the indoor unit 5 and the MF unit 3. Air circulation is generated between the MF unit 3 and the room can be air-conditioned more efficiently.

  Next, the flow of the voice guidance mode according to the fourth embodiment of the present invention will be described with reference to FIG. In the voice guidance mode, when the driving information is notified by voice, either the indoor unit 5 or the MF unit 3 is appropriately selected. The voice guidance mode described below is when both the indoor unit 5 and the MF unit 3 are turned on, and various voices to be guided are built into the indoor unit 5 or the MF unit 3. Emitted from a speaker (not shown).

  In the voice guidance mode, the control unit 7 checks whether or not the indoor unit 5 is in the “main body voice mode” (ST210), and determines that it is in the “main body voice mode” (ST210-Y). Performs voice guidance only from the main body of the indoor unit 5 (ST211).

  When it is determined that the “main body voice mode” is not set (ST210-N), the control unit 7 next determines whether the “MF voice mode” is set (ST212) and enters the “MF voice mode”. When it is determined that it is not set (ST212-N), voice guidance from the MF unit 3 is not performed (ST213).

  If it is determined that the “MF audio mode” is set (ST212-Y), the control unit 7 next determines whether or not there is a person near the indoor unit 5 by the human detection sensor 50 (ST214). When a person is present in the vicinity of the indoor unit 5 (ST214-Y), voice guidance is provided from the main body of the indoor unit 5 (ST215).

  When it is determined that a person is not present in the vicinity of the indoor unit 5 (ST214-N), the control unit 7 further determines whether the room is dark using an illuminance sensor (not shown) (ST216). If it is dark (ST216-Y), voice guidance is provided from the MF unit 3 (ST217). Conversely, when it is determined that the room is bright (ST216-N), voice guidance is provided from the main body of the indoor unit 5 (ST218).

  According to this, when there is a person near the indoor unit 5 or when a room such as daytime is bright, voice guidance is basically given from the indoor unit 5 and in a dark place such as at night, the MF unit 3 Voice guidance can be performed from. Thereby, since the sound is output from the MF unit 3 located at a lower position than the indoor unit 5 provided in the upper part of the living room, the volume can be reduced or it is close to the user, so that it is easy to hear.

  In addition, after the indoor unit 5 notifies the setting content of the air conditioner unit 2, the control unit 7 notifies the MF unit 3 that the indoor unit 5 has finished the notification, and receives the notification to set the MF unit 3. The contents may be notified by the MF unit 3. Thereby, the notification timings of the indoor unit 5 and the MF unit 3 do not overlap, and the user can surely know the notification contents.

  Next, with reference to FIG. 10 a, b, the ventilation switching mode of the air conditioning system by 5th Embodiment is demonstrated. This operation mode is for setting the ventilation of the indoor unit 5 or the MF unit 3 when the MF unit 3 is moved outside the ventilation range of the indoor unit 5. In addition, although there exists a ventilation mode based on arbitrary programs other than a strong wind and a weak wind about a ventilation mode, in this embodiment, about a specific ventilation mode, it is an arbitrary matter.

When blowing switching mode is selected, the air conditioner unit 2, after performing the MF position detection process A, it performs position detection of the MF unit 3, a range MF unit 3 to reach the wind indoor unit 5 (blast It is determined whether it is within the range (ST180), and if it is determined that it is within the blowing range (ST180-Y), the operation is continued (ST181).

When it is determined that it is outside the blowing range (ST180-N), after notifying the MF unit 3 that it is outside the blowing range (ST182), it is confirmed whether or not there is an input to continue the blowing mode (ST183). In case of no continuing (ST183-N) is increasing the rotation speed of the blower fan of the air conditioner unit 2 (ST186), the process proceeds to ST187. When there is continuation (ST183-Y), after notifying the MF unit 3 of continuation (ST184), the operation is continued (ST185), and the process proceeds to ST187.

  Next, it is confirmed whether or not the mode end information has been received (ST187). If not received (ST187-N), the above steps are repeated from the beginning. If it is received (ST187-Y), the MF unit 3 is notified of the end of the air blowing switching mode (ST188), and then the process ends.

  After performing the MF position detection process B, the MF unit 3 confirms whether or not there is a notification that it is out of the blowing range (ST280), and if there is a notification outside the blowing (ST280-Y), a notification of mode continuation is issued. If there is no notification of mode continuation (ST281-N), the operation is stopped (ST282). When there is a notification of mode continuation (ST281-Y), the operation is performed in the stirring mode (ST283), and the process proceeds to ST285. When there is no notification of outside air (ST280-N), the operation state is maintained (ST284), and the process proceeds to ST285.

  Next, it is confirmed whether or not the mode end information has been received (ST285). If it is determined that there is no reception (ST285-N), a series of steps are repeated until reception information is obtained. If it is determined that there is reception (ST285-Y), the process ends.

According to the ventilation switching mode shown in FIG. 10, when the MF unit 3 is separated from the indoor unit 5, the operation is performed with energy saving by performing the ventilation in the setting mode without intentionally blowing. be able to. Moreover, when sending forcibly, indoor air can be circulated by raising the ventilation fan rotation speed of the indoor unit 5.

Next, with reference to FIG. 11 a, b, the ventilation range switching mode of the air conditioning system by 5th Embodiment of this invention is demonstrated. In this operation mode, the ventilation of the indoor unit 5 and the MF unit 3 is interlocked according to the distance between the indoor unit 5 and the MF unit 3. When the blowing range switching mode is selected, the air conditioner unit 2, after performing the MF position detection process A, weak wind range MF unit 3 is in a range in which the wind arrives at the weak wind air volume of the indoor unit 5 check whether the inner (ST 190), when it is determined that the range of weak wind (ST 190-Y) is a blower fan of the air conditioner unit 2, Jakukaze operation (ST191).

If it is determined that the wind is out of the weak wind range (ST190-N), it is next checked whether the MF unit 3 is in the midwind range (ST192). If it is determined to be within the scope of the paralytic (ST192-Y), the blower fan of the air conditioner unit 2, paralytic operation (ST193).

When it is determined that it is out of the medium wind range (ST192-N), it is confirmed whether the MF unit 3 is within the strong wind range (ST194). If it is determined to be within the scope of the strong wind (ST194-Y), the blower fan of the air conditioner unit 2, strong wind operation (ST195). If it is determined that the wind is out of the range (ST194-N), the MF unit 3 is notified of the outside of the air blowing range (ST196), and then the operation is continued (ST197).

  Next, it is confirmed whether mode end information has been received (ST198). If not received (ST198-N), the above steps are repeated from the beginning. If received (ST198-Y), the MF unit 3 is notified of the end of the air blowing range switching mode (ST199), and then the process ends.

  After performing the MF position detection process B, the MF unit 3 confirms whether or not it has been notified that it is out of the blowing range (ST290), and if received the notification (ST290-Y), it is out of range. After displaying that there is (ST291), the operation before the mode switching is continued (ST292).

  When not notified (ST290-N), a stirring operation is performed (ST293). Next, it is confirmed whether or not the mode end information has been received (ST294). If it is determined that there is no reception (ST294-N), a series of steps are repeated until reception information is obtained. If it is determined that there is reception (ST294-Y), the process ends.

  According to the invention described in FIG. 11, depending on the distance between the indoor unit 5 and the MF unit 3, when the indoor unit 5 and the MF unit 3 are linked to each other, It automatically becomes strong wind operation, and when it goes out of the range of strong wind operation, it is displayed, so finer temperature control can be performed.

Next, with reference to FIGS. 12a and 12b, a position detection method according to a sixth embodiment of the present invention will be described. First, by operating the operation unit 44 of the remote controller 4, with turn of the air conditioner unit 2 (ST 300), it turns ON the MF mode for interlocking the MF unit 3 and the air conditioner unit 2 (ST 301).

  Accordingly, if the power of the MF unit 3 is not turned on (ST302-N), the control unit 7 transmits an ON signal to turn on the power to the MF unit 3 (ST303).

Thereafter, when the power of the MF unit 3 does not become ON (ST304-N) displays a message indicating a communication error (ST 305), the air conditioner unit 2 performs islanding operation (ST 306). Here, the control unit 7 turns on the power of the MF unit 3, but the power of the MF unit 3 may be turned on directly by the remote controller 4.

When the power of the MF unit 3 is ON (ST302-Y), request the position information to the MF unit 3 (ST307), and confirm whether the specific wavelength is detected by the thermopile 59 provided in the indoor unit 5 (ST308). In the case where the specific wavelength is not detected (ST 308-N), and outputs (ST 309) a detection error on the display unit 57, an air conditioner unit 2 performs islanding operation (ST 310). When the detection information is obtained (ST308-Y), the detection completion information is transmitted to the MF unit 3 (ST311), and the position detection is finished (ST312).

  Here, the thermopile 59 measures the floor surface of the room R by dividing it into a plurality of areas, and identifies the position of the MF unit 3 depending on which area the specific wavelength from the MF unit 3 is detected. is there.

Next, the operation of the MF unit 3 will be described. MF unit 3, after receiving the ON signal from the air conditioner unit 2 (ST400), the power of the MF unit 3 checks whether ON (ST 401). If the power is not ON (ST401-N), the power is turned on (ST402), and the process proceeds to ST403. If the power is on (ST401-Y), the process proceeds to ST403.

  Thereafter, a position information request signal is received from the main body (ST403), and the infrared transmitter 37 blinks at a predetermined interval to transmit a specific wavelength (ST404). Then, the MF unit 3 confirms whether or not the detection completion information has been received (ST405), and if not received (ST405-N), outputs a detection error to the display unit 85 (ST407) and ends (ST408). ). If received (ST405-Y), the process ends as normal termination (ST406).

  According to the position detection method described in FIG. 12, the positional relationship between the indoor unit 5 and the MF unit 3 is performed via the thermopile 59 and the infrared transmission unit 37, so that accurate position information of the MF unit 3 can be easily obtained. You can investigate.

  As described above, according to the air conditioning system of the present invention, the air sent from the indoor unit 5 is relayed through the MF unit 3 so that the air is delivered to a place that the indoor unit 5 does not reach directly, Can be circulated and returned to the indoor unit 5 again, so that energy-saving and efficient operation is possible. The present invention is not limited to the embodiment described above.
