Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art A conventional air conditioner is provided with an indoor space completely partitioned by walls or the like as a region to be air-conditioned. Such an air conditioner has a basic configuration of discharging hot air (at the time of cooling) or cold air (at the time of heating) generated in the process of air conditioning to the outside through an outdoor unit.

[0003]

However, in a small section where the upper part seen in the office is divided by a partition that does not reach the ceiling, the upper part of the partition is open, but the air in the room is not stirred by the air conditioning equipment. Therefore, it was difficult to air-condition the small section without unevenness.

[0004] In this case, it is difficult to obtain a desired room temperature in a range where the stirring of the indoor air by the air conditioner can be expected, that is, in a small section located around the indoor unit of the air conditioner. As a solution to this, it can be considered to provide at least one outlet for each small section, but in this case, there is a problem that installation work for the outlet is required.

As another solution, it is conceivable to provide a plurality of indoor units of an air conditioner for each of the plurality of small sections. As described above, hot air and cool air generated during the air conditioning process are discharged to the outside. Therefore, the indoor unit and the outdoor unit must be connected with refrigerant piping. But,
When the size, position, and the like of the small section are changed by moving the partition, the movement of the indoor unit and the relocation work of the piping are required, so that there is a problem that the movement of the partition becomes difficult.

Further, even if the conventional indoor unit of the air conditioner has a small air conditioning capacity, it needs to be fixed to the upper part of the wall due to the necessity of stirring the indoor air. Had a problem that installation work was required.

[0007] When dehumidification is performed by a conventional air conditioner, the heat exchanger of the indoor unit of the air conditioner is cooled and dew condensed on the heat exchanger, so that there is a problem that the blowing temperature of the air conditioner decreases. .

[0008] In view of the above problems, the present invention enables air-conditioning to be performed without unevenness even in a room divided into a plurality of small sections by partitioning or the like, and is extremely easy to install and relocate. It is intended to provide a device.

[0009]

The first and second radiators 22A and 22B are screwed to the support plate 24 by bolts made of synthetic resin to prevent heat conduction, and the back surfaces of the radiators 22A and 22B are
A to 21H. In addition, silicone grease is applied to the crimping surface in order to achieve good heat conduction. On the other hand, the third and fourth radiators 23A and 23B
In order to achieve good heat conduction, the support plate 24 is screwed to the support plate 24 with bolts made of aluminum alloy, and silicon grease is applied to the back surface and the contact surface of the support plate 24.

On the surface of the support plate 24 on the front panel 2 side,
A heat insulating material 25, which is a sheet made of urethane resin, is adhered except for a portion where the Peltier elements 21A to 21H are provided. The heat insulating material 25 is slightly thicker than the Peltier elements 21A to 21H, and the first and second radiators 22A and 22B.
When is pressed to the Peltier element, the elastic restoring force can completely seal the periphery of the Peltier element. For this reason, water drops due to dew condensation form the Peltier element 21A.
To 21H is prevented.

At the center of the support plate 24, a plurality of slits 24A are arranged in a row in the horizontal direction.

The configuration of the heat exchanging means is not limited to the above configuration, as long as thermal coupling between the Peltier element and each radiator is ensured.

Below the first radiator 22A and the second radiator 22
Below B, trays 31 and 35 for collecting dew water generated on the surface of the radiator are provided, respectively. As will be described later, during cooling, dew condensation occurs in the first and second radiators 22A and 22B. As shown in FIG. 6, an inclined surface is provided below these radiators. All the condensed water is guided along the inclined surface, and is stored in the trays 31 and 35.
Note that the third and fourth radiators 23A and 23B do not have the inclined portions of the first and second radiators 22A and 22B. It is provided along.

The trays 31 and 35 have drain holes 3 respectively.
Drainage pipes 33, 37 are provided via 2, 36. The drain pipes 33 and 37 pass through the partition plate 8 and are guided to the inside of the evaporation tank 80 (see FIG. 1).
Therefore, the dew water is stored in the evaporating tank 80 through the drain pipes 33 and 37. A water level sensor 76 and a heater 83, which will be described later, are provided inside the evaporating tank 80.

In the evaporating tank 80, the lower end of a net 81 made of antibacterial synthetic fiber which is supported on the back surface of the back panel 3 by a support pin 82 and is separated from the back panel 3 is located. The dew condensation in the evaporating tank 80
And is evaporated in the second passage 42. In addition, the evaporating tank 80 and the net 81 constitute an evaporating means of the condensed water. However, the evaporating means is not limited to this structure as long as the evaporating means accelerates the evaporation of the condensed water by exhaust heat.

Next, a plurality of sensors provided in the present air conditioner will be described. As shown in FIG.
A first room temperature sensor 71 disposed below the air inlet 11 of the air conditioning area of the front panel 2 is a temperature sensor for measuring the room temperature above the air conditioning area.
The second room temperature sensor 72 disposed above the air outlet 13 of the air conditioning area is a temperature sensor for measuring the room temperature below the air conditioning area.

As shown in FIG. 1, the first passage 12
A temperature sensor 73 for measuring the outlet temperature is provided inside the air conditioner and immediately above the air outlet 13 of the air conditioning area. This sensor 73 is controlled by a rod 73A.
It is arranged at the center of the inside of the first passage 12 so that accurate measurement of the blowing temperature can be performed.

As shown in FIG. 1, the first and second
The fin bases of the radiators 22A and 22B have the first
And a temperature sensor 7 for measuring the temperature of the second radiator
4, 75 are provided. These two temperature sensors are provided for confirming the proper operation of the Peltier element, and are not always necessary for implementing the present air conditioner.

Since the temperature of the radiator can be measured indirectly by measuring the temperature of the radiator as in the case of these two temperature sensors, the temperature sensor 73 is omitted by providing the temperature sensor. You can also. Further, a water level sensor 76 for measuring the level of dew water in the evaporation tank 80 is provided on a side wall of the evaporation tank 80.

Next, the operation of the above embodiment will be described separately for cooling, dehumidifying, and heating. 7 (1) and 7
(2) is an explanatory view showing an installation state of the present air conditioner.
Inside the room 100 partitioned by the ceiling 103, the wall 104, and the floor 105, small partitions 120 partitioned by partitions 110 on four sides are formed. This room 1
At 00, the air outlet 101 of an air conditioner (not shown) is provided above the wall 104 so that the entire room 100 is an air conditioning target area.
And a suction port 102 are provided. The present air conditioner is erected on the floor surface 105 along the inner wall surface 110 of the partition, and forms an air conditioning target area in the internal space of the small section 120. Reference numeral 111 denotes a door provided in a part of the partition 110.

As is apparent from the position of the partition shown in FIG. 7, the cool air or warm air blown out from the outlet 101 becomes an obstacle by the partition 110 and efficiently agitates the air in the small compartment 120. Can not do. For this reason, in the summer, the temperature of the internal space of the small section 120 cannot be efficiently reduced, and in the winter, the temperature of the internal space cannot be efficiently increased.

First, the operation of the air conditioner during cooling will be described. When the air conditioner is operated by operating the control panel 70A, the supply of DC current to the first fan 15, the second fan 45, and the Peltier elements 21A to 21H is started. The first fan 15 is connected to the air conditioning area outlet 13.
A predetermined voltage is supplied so that the blowing speed at the opening of the nozzle becomes a blowing speed of 2.0 m / sec or less. The phase of the DC current supplied to the Peltier elements 21A to 21H is positive.

When a current having a positive phase is supplied, the surfaces of the Peltier elements 21A to 21H are cooled on the first and second radiators 22A and 22B, and the third and fourth radiators 23A and 23B are cooled.
The connection is made so that the side surface is heated. Therefore, the first and second radiators 22A and 22B are cooled, and at the same time, the third and fourth radiators 23A and 23B are heated. For this reason, the air introduced into the first passage 12 from the suction port 11 is cooled by passing through the first and second radiators 22A and 22B, while being introduced into the second passage 42 from the suction port 41. The heated air is heated by passing through the third and fourth radiators 23A and 23B.

The electric power supplied to the Peltier elements 21A to 21H is controlled so that the cool air temperature of the outlet 13 is determined based on the desired room temperature of the user. The temperature of the cold air is determined in conjunction with the set temperature of the control panel 70A (details will be described later).

In a conventional air conditioner, extremely low-temperature cold air is blown out, the blowing speed is increased, and the room air is cooled as a whole by vigorously stirring with high-temperature room air. Specifically, in this conventional air conditioner, the blowing temperature of the cool air is 3 ° C. or less, and the blowing speed is 3.0 m / sec or more, no matter how low. When the cool air temperature and the blowing speed of the conventional air conditioner are applied to the present air conditioner, the following problems occur.

First, in the present air conditioner, since the outlet 13 is located just above the floor in the room, when the temperature of the cold air is extremely low, the feet tend to be very cold. Second
In order to make the cold air temperature extremely low, it is necessary to increase the cooling capacity. In order to increase the cooling capacity of the Peltier element, it can be achieved by increasing the power supply to the Peltier element. However, it is known that the life of the Peltier element is shortened at an accelerated rate as the power supply is increased. This is one of the reasons why the use of the Peltier element in the air conditioner is not widespread.

Third, when the blowing speed of the cold air is increased,
Similar to the second problem, there is a problem that the thermal load on the Peltier element increases and the life of the Peltier element is shortened. This is because a large thermal stress is applied to the semiconductor chip constituting the Peltier element, and further, a large thermal deformation of the radiator, which is a holding member of the Peltier element, causes a gap to be generated around the Peltier element. The inability to achieve is a major factor. Peltier elements have high heat conversion efficiency and have excellent characteristics that can avoid the use of chlorofluorocarbon as a refrigerant, but they were not actively used in air conditioners because they solve the problem of the life of Peltier elements. Because he couldn't.

In this air conditioner, since the blowing temperature is high,
Since the first problem can be solved and the blowing temperature is high and the blowing speed is low, the thermal load on the Peltier element can be extremely reduced. Therefore, the problem of the life of the Peltier element can be solved,
We could open the way to use Peltier elements in air conditioners.

Next, the present air conditioner is characterized in that the heat of the Peltier element is not discharged outside the room. The air-conditioning target area of the present air-conditioning apparatus is an air-conditioning target area 131 in the small section 120 located below the boundary 130 of the air-conditioning area between the heat exchange air suction port 41 and the air-conditioning area air suction port 11.
It is. Since the cool air blown out from the blowout port 13 has an extremely low blowout speed of 2.0 m / sec or less, the cool air spreads over the floor without stirring with the air in the area 131. This is because the specific gravity between the Coanda effect and the cool air, which will be described later, is greater than the warm air in the region. The cool air layer gradually increases while pushing up the warm air in the area 131, and the upper portion of the cool air layer reaches the boundary 130. And
When the boundary 130 is reached, this time, the air is sucked in from the suction port 11 and is blown out again from the outlet 13, and the area 13
Circulate in 1.

Therefore, the air is hardly agitated between the area 131 and the unmanaged area 132 located above the boundary 130. Therefore, the present air conditioner only needs to cool the space having a relatively small capacity, that is, the air-conditioning target area 131, so that the heat load on the Peltier element can be reduced.

Further, in the present embodiment, in order to reduce the load on the Peltier element, a characteristic variable control of the blowing temperature is performed. In principle, the temperature of the blown cold air is set to be substantially equal to the room temperature desired by the user. However, since the air in the air conditioning target area 131 is cooled while forming a temperature stratification, the present air conditioner performs variable control such that the blow-out temperature is gradually reduced immediately after the cooling operation of the present air conditioner. For example, when the temperature on the floor surface side of the area 131 (the value of the second room temperature sensor 72) is a relatively high temperature of 35 ° C. and the set temperature of the control panel 70A is a relatively low temperature of 18 ° C., the blowing is performed. Assuming that the temperature is 18 ° C., which is the user's desired room temperature, the room air introduced into the first passage 12 must be reduced by 17 ° C. by the Peltier device. However, the control unit 70 sets the outlet temperature immediately after the start of cooling to 10 ° C. lower than the value of the second room temperature sensor 72.
The amount of power supply to the Peltier device is determined so that the blowing temperature is relatively high at 5 ° C.

Further, within a few minutes from the start of the air conditioning, the upper part of the cold air layer reaches the boundary 130, and the temperature on the upper side of the area 131 (the value of the first room temperature sensor 71) decreases. The control unit updates the setting of the cool air temperature. For example, the initial value of the first room temperature sensor 71 is 35
If the temperature is lowered to 34 ° C., the power supply is updated so that the value of the temperature sensor 73 at the outlet temperature becomes 24 ° C., and if the temperature is further lowered to 33 ° C., the value of the temperature sensor 73 becomes 23 ° C. It is updated so that it becomes ℃. The update of the cool air temperature is programmed based on an average value of the first room temperature sensor 71 and the second room temperature sensor 72 (strictly, based on an isotherm assumed from the distance between the first room temperature sensor 71 and the second room temperature sensor 72). (Calculated by the above formula) until the temperature reaches 18 ° C., and the final blowing temperature is lower by about 1 ° C. than the set temperature (to take into account thermal energy diffusion loss).

In this case, the Peltier element receives only a heat load that reduces the air introduced into the first passage 12 by at most 10 ° C., so that the life of the Peltier element can be maintained long. In addition, at the time of cooling, since the room temperature can be managed only by the first temperature sensor 71, the second room temperature sensor 72 is not necessarily required.

Next, an air conditioner usually requires an outdoor unit to discharge heat, but the present air conditioner does not require a so-called outdoor unit. The exhaust heat of the air conditioner is supplied to the air exchange port 4 for heat exchange located above the air intake port 11 for the air conditioning area.
By blowing hot air upward from 7, the air is blown to the upper region 132 of the air conditioning target region 131. Since the hot air blown out as the exhaust heat has a low specific gravity, the upper region 1
32 and the suction port 1 provided in the room 100
02 is released outside the room. Since the hot air has a low specific gravity, it does not advance downward.
It does not agitate with the air of 31 and does not raise the temperature of the area.

Further, a heat exchange air inlet 41 for introducing air for exhaust heat, ie, heat exchange air, is located above the air inlet 11 for the air conditioning area. For this reason, the heat exchange air is supplied from the upper region 132, and the cooled air layer in the cooled air conditioning target region 131 is not used as the heat exchange air. Therefore, since the cool air layer is not affected by the exhaust heat at all, the air conditioning efficiency of the air conditioning target area can be kept high, contributing to energy saving.

In the present air conditioner, the exhaust heat is performed by the air for heat exchange. For example, a liquid cooling system as described in a third embodiment to be described later can be adopted. In this case, exhaust heat using a radiator or the like is performed on the upper region 132 of the air conditioning target region 131.

In the present air conditioner, there is no need to provide a means for discharging the dew water generated during cooling to the outside of the room, that is, a drain pipe which is indispensable for the conventional air conditioner. First
Condensed water condensed on the surface of the radiator along with the cooling of the second radiator 22A, 22B is guided along the inclined surface below the radiator and collected in the trays 31, 35. Further, the condensed water flows from the tray through the drain holes 32 and 36 into the drain pipes 33 and 37, and is finally stored in the evaporation tank 80. The condensed water in the evaporating tank 80 is directly evaporated from the water surface of the evaporating tank 80, or is sucked up by the net 81 and heated in the second passage 42 heated by the heat radiation of the third and fourth radiators 23A and 23B. Evaporated by airflow.

As described above, since the condensed water is vaporized without being discharged from the air conditioner as a fluid, a means for discharging the condensed water is unnecessary. The hot air containing the humidity is supplied to the upper region 132 of the air-conditioning target region 131 as described above, and is discharged from the suction port 102 of the room 100 to the outside.

In the present air conditioner, since the first passage 12 extends in the vertical direction, the heat exchange unit 20 can be disposed in the vertical direction. For this reason, the present air conditioner is of a stationary type and has a vertical overall shape, so that it can be configured to be extremely slim. This eliminates the need for installation work,
The installation area is extremely small. This simplicity is not found in conventional air conditioners. Further, as compared with a conventional air conditioner that uses chlorofluorocarbon or the like as a refrigerant, there is an advantage that it is extremely lightweight because it does not require a means for compressing the refrigerant. For this reason, it is possible to realize the easiness of movement that the conventional air conditioner could not do.

In the implementation of the present air conditioner, the outlet 101 and the inlet 102 for forcibly ventilating the air in the upper region 132 are not always necessary. For example, when the ceiling is high and the volume of the upper region is large, the heat energy of the hot air in the upper region 132 is diffused from the wall surface or the ceiling located in the region to the building body of the building. In addition, if a ventilation port that is simply connected to the outside or a corridor is provided instead of the air outlet 101 and the air inlet 102, the diffusion of heat energy is further promoted.

Next, the operation of the present air conditioner at the time of dehumidification will be described. The dehumidification of the present air conditioner is characterized in that a decrease in room temperature during dehumidification, which cannot be avoided by a conventional air conditioner, is eliminated. When an instruction for the dehumidifying operation is given to the operation panel 70A, the control unit 70 sets the Peltier devices 21A to 21A to 2D.
A positive-phase DC current is supplied to 1D, while a negative-phase DC current is supplied to Peltier elements 21E to 21H. The voltage value and current value of each DC current are the same.

By this power supply, the first radiator 22A is cooled, and at the same time, the second radiator 22B located on the downstream side is cooled.
Is heated. The air introduced into the first passage 12 is
When passing through the radiator 22A, it is cooled and dewed and dehumidified. Furthermore, the second radiator 22B located on the downstream side
When passing through, the temperature of the air becomes equal to the temperature immediately after the introduction. Therefore, generation of cool air during dehumidification is prevented.

The dew water condensed on the surface of the first radiator 22A is evaporated by the evaporating tank 80 and the net 81, then blown up to the upper region 132, and discharged from the suction port 102 of the room 100 to the outside. You. Further, since the dew water is collected by the tray 31, the dew water does not fall on the second radiator 22B. The third radiator 23A provided on the back side of the first radiator 22A is overheated, and the fourth radiator 23B provided on the back side of the second radiator 22B is cooled. Therefore, the air introduced into the second passage 42 is heated by the third radiator 23A, cooled by the fourth radiator 23B, and returned to the temperature at the time of introduction. The amount of dew water condensing on the surface of the fourth radiator 23B is relatively small.

The water level sensor 76 is provided inside the evaporation tank 80.
And a heater 83 are provided. When the amount of dew water stored in the evaporation tank 80 increases and exceeds a predetermined water level, the water level sensor 76 transmits a detection signal to the control unit 70. The control unit 70 that has received the detection signal supplies power to the heater 83 to increase the temperature of the stored water in the evaporating tank 80, and forcibly evaporates the dew condensation water. Sensor 76
Is stopped, the power supply to the heater 83 is stopped.

Next, the operation of the air conditioner during heating will be described. When the air conditioner is operated by operating the control panel 70A, the supply of DC current to the first fan 15, the second fan 45, and the Peltier elements 21A to 21H is started. The first fan 15 is connected to the air conditioning area outlet 13.
Blow speed at the time of steady operation at the opening of
A predetermined voltage is supplied such that the blowing speed is equal to or less than / sec. The polarity of the direct current supplied to the Peltier elements 21A to 21H is opposite.

When the currents of opposite phases are supplied to the Peltier elements 21A to 21H, the surfaces of the first and second radiators 22A and 22B are heated, and the third and fourth radiators 23A and 23B are heated.
The side surface is cooled. For this reason, the air introduced into the inside of the first passage 12 from the suction port 11 is heated by passing through the first and second radiators 22A and 22B.
The air introduced from the suction port 41 into the second passage 42 is cooled by passing through the third and fourth radiators 23A and 23B.

The electric power supplied to the Peltier elements 21A to 21H is controlled so that the temperature difference between the temperature of the hot air at the outlet 13 and the temperature of the indoor cool air is 10 ° C. or less. The temperature of the hot air is determined in conjunction with the set temperature of the control panel 70A. The blowing speed of the hot air is 2.0 m / sec.
It is as follows.

The basic principle of the operation of the air conditioner during heating (stratified air conditioning method) will be described. A stratified air conditioning method using this principle is disclosed in Japanese Patent No. 3082061. This patent invention, which was filed by the present applicant, is an air-conditioning method of a lower blow-out and suction type using a general fan coil type air conditioner. However, in the present air conditioner, by using the Peltier element, stratified air conditioning during heating can be provided in a complete state with higher stability.

In the above Japanese Patent No. 3082061,
"The hot air temperature is set such that the temperature difference from the room temperature is within 10 ° C., an outlet is provided below the room, and the outlet blows hot air horizontally to the floor surface, and the blowing speed is 2.0 m.
/ Sec or less, and a suction port is provided at a predetermined height on the wall side of the indoor space with reference to the living space of the human body, animals and plants, "a heating air conditioning method" is disclosed.

When a high-temperature hot air is blown out from below the room vigorously (usually at least 3.0 m / sec) by the conventional air conditioning method, the distribution of the warm air is as shown in FIGS. FIG. 8 shows a case in which warm air is blown in a direction perpendicular to the floor, and FIG. 9 shows a state in which warm air is blown in a direction horizontal to the floor.

In the method shown in FIG. 8, the specific gravity is light because the temperature of the hot air is high, and warm air is distributed so as to rise toward the ceiling surface due to the inertia blown upward. Next, in the method shown in FIG. 9, since the specific gravity is also light, warm air is distributed away from the floor surface.

These methods attempt to heat the entire room by stirring warm air with cool air in the room, and it is necessary to blow vigorously high-temperature warm air in order to sufficiently perform the stirring. Therefore, in a region where the stirring is not sufficiently performed, the cold air mass still exists, and the entire room cannot be heated evenly. In addition, since a warm air mass (hot air) formed by warm air is distributed in the upper part of the room, there is a problem that the feet are cold and the area around the face is hot.

In the above Japanese Patent No. 3082061,
First, the temperature difference between the hot air and the room temperature was set to 10 ° C. or less, so that the specific gravity of the cold air existing in the vicinity was not excessively reduced. For this reason, the force by which warm air tends to separate from the floor surface can be reduced.

Second, an outlet is provided below the room, and hot air is blown out from the outlet in a horizontal direction with respect to the floor surface, so that warm air formed by the warm air has a Coanda effect (coan effect).
(effect). This Coanda effect was developed by Henry Coanda of Romania (1972).
Is an airflow phenomenon discovered in 1932
This is an airflow phenomenon in which an airflow blown close to a wall surface or a ceiling surface tends to be attracted to, adhere to, and flow toward the surface. In this case, one side (side not in contact with the wall etc.)
Since only the gas is diffused, it has the property that the attenuation of the velocity is smaller than that of the free jet and the reaching distance is longer.
That is, the component requirement of “providing an air outlet below the room and blowing out the warm air from the outlet in a horizontal direction to the floor” is necessary for causing the warm air formed by the warm air to crawl on the floor. Requirements.

Third, by setting the blowing speed to 2.0 m / sec or less, it is possible to prevent the stirring of the warm air and the cool air formed by the warm air. If the warm air and the cool air are agitated, a turbulent flow occurs, and the above-mentioned Coanda effect cannot be maintained. In addition, by setting the speed, even when the partition exists close to the outlet, the blowing speed is sufficiently low so that the warm air collides with the partition and does not agitate with the cool air, but spreads in the horizontal direction. Wrap around the back side of the partition (see FIG. 10).

Next, a heating state by the air-conditioning method of Japanese Patent No. 3082061 will be described with reference to FIGS. FIG. 11 is a cross-sectional view of the relationship between warm air and indoor cool air that are spreading on the floor at the start of heating as viewed from the side.
Between the warm air and the floor surface, there is a floor cold air layer cooled by the cold floor surface, while indoor cool air exists above the warm air.

The floor cool air layer under the warm air has a higher specific gravity than the indoor cool air, so that the relationship between the warm air and the floor cool air layer is in a normal state in terms of the specific gravity. Next, the relationship between the warm air and the indoor cool air has a reversal phenomenon from the viewpoint of specific gravity.
This reversal phenomenon is that the specific gravity difference between warm air and cold air is small, warm air is spreading to the floor so that indoor cool air can not go under the warm air, and warm air maintains horizontal inertia due to the Coanda effect. And it is maintained for three reasons: it is unlikely to rise. Therefore, the warm air formed by the warm air spreads over the entire floor surface while displacing the indoor cool air.

Since the suction port is provided at a predetermined height with respect to the living space, only indoor cold air is sucked from the suction port as shown in FIG. Therefore, the warm air and the cool air are replaced, and the room temperature can be rapidly raised to a predetermined temperature (see FIG. 13).

The above Japanese Patent No. 3082061 is realized by using a general fan coil type air conditioner. In this fan coil type heater, the indoor air is heated by the fan coil. Therefore, when the indoor cool air before the start of heating is extremely low, the temperature of the hot air blown out from the outlet is also correspondingly low (room temperature). And the temperature difference is 10
° C), and does not reach a high temperature of 22 ° C to 35 ° C. For example, when the room is at 0 ° C., the temperature of the warm air in the initial state is around 8 ° C.

However, in such a fan coil type heating device, since the heat capacity of the fan coil and the refrigerant is large, the outlet temperature (warm air) is always higher than the room cold air temperature at the outlet upper end height that changes every moment. There is a problem that a time lag occurs to properly control the temperature). That is, in the fan coil type heating device, when the temperature of the fan coil is too high, the temperature must be lowered, but for that, a certain amount of time is required because the heat capacity of the fan coil and the like is large. is there.

The time required for controlling the blow-out temperature has a problem in that the above-described reversal of the warm air and the indoor cool air is adversely affected. First, if the blowing temperature is too high,
Once the warming layer separates from the floor surface and the resulting rising airflow of the warm air is once formed, the subsequent warm air also has a suction force in the upward direction. For this reason,
Even when the temperature returns to the appropriate temperature, the peeling phenomenon continues for a long time.

Second, although the Coanda effect works strongly in the direction of warm air travel, the inertia force is weak in the lateral direction of the warm air travel, so there is a high possibility that indoor cool air will flow below warm air. . For this reason, once the indoor cool air forms an airflow circling below the warm air, the Coanda effect is inhibited for a certain long time, and the phenomenon of the warm air separating from the floor surface continues. In particular, this phenomenon becomes more serious as the width of the outlet becomes narrower. That is, when the width of the outlet is narrowed, the width of the blown warm air layer is narrowed, so that the tendency of the indoor cool air to flow below the warm air is increased.

The problem of the above-mentioned air conditioning method at the time of heating can be solved by maintaining the blow-out temperature appropriately and extremely precisely and quickly. Therefore, in the present invention, the use of a Peltier element eliminates the need for a refrigerant and minimizes the heat capacity of the apparatus. For this reason, the temperature of the warm air blown out from the outlet can be reduced in a short time, and it is possible to completely secure stratified air conditioning during heating.

Further, in the present invention, by providing a room temperature sensor, the temperature of the indoor cool air is accurately measured, and the blowout temperature is controlled based on the temperature of the indoor cool air. The blowing temperature is set such that the temperature difference from the indoor cold air is 10 ° C. or less.

Further, the room temperature sensor may be provided anywhere except the vicinity of the outlet, but it is particularly preferable that the room temperature sensor 72 is provided immediately above the outlet. This is because it is possible to accurately measure the temperature of the cool air positioned immediately above the blown warm air, and to realize precise control of the temperature of the blown warm air.

Note that the cool air blown upward from the heat exchange air outlet 47 of the air conditioner at the time of heating is diffused into the upper region 132 of the air conditioning target region 131, so that the cool air is blown to the air conditioning target region 131. There is no thermal effect.
Normally, since hot air such as a human body and lighting fixtures stays in the upper region 132, the cool air blown out from the heat exchange air outlet 47 does not fall to the air conditioning target region 131. Further, the third and fourth radiators 23A, 23A
The dew water generated in B evaporates as it is on the radiator surface, or falls into the evaporating tank 80 and evaporates by the net 81 or the like.

Since the apparatus of the present embodiment can be installed on the floor surface, installation work on the wall surface is unnecessary. Also,
The lower end of the air inlet 11 of the air conditioning area of the present air conditioner is located at a height of 1500 mm from the floor, and this height can be appropriately designed according to the desired height of the air conditioning target area. For example, in the case of a bedroom, the height of the suction port from the floor can be set to about 800 mm.
That is, the air inlet 11 in the air conditioning area is provided at a predetermined height based on the living space of the human body, animals and plants.

Further, due to the precise control of the Peltier element, the width of the air outlet 13 in the air conditioning area of the present air conditioner is extremely narrow, about 250 mm. This width can be reduced by half when the Peltier elements are arranged in one row instead of being arranged in two rows as in the present air conditioner, and with a minimum area that cannot be considered in a conventional air conditioner. Installation is possible.

Next, a second embodiment will be described with reference to FIGS. In the second embodiment, the heat of the air conditioner of the first embodiment is exhausted to the outside of the room. It is also possible to take in a small amount of fresh air outside the room into the room and discharge a small amount of contaminated air in a non-management area in the room outside the room. It should be noted that reference numerals for members that perform the same functions as those in the first embodiment are indicated by the same numbers.

Reference numeral 201 denotes an outside air introduction pipe which penetrates a wall surface (not shown) and opens to the outside. Reference numeral 21
Reference numeral 0 denotes an exhaust pipe, which penetrates a wall surface and opens outdoors.
The outside air introduction pipe 201 introduces outside air into the second passage 42, and the exhaust pipe 210 exhausts hot air (for cooling) and cold air (for heating) in the second passage 42 to the outside. Note that reference numeral 206 provided in the second passage 42 is an outside air introduction fan, and reference numeral 211 is an exhaust fan. If the fan blowing capacity can be ensured, one of the fans can be omitted.

The outside air introduction pipe 201 is provided with a filter 202 for removing dust and the like from outside air. Further, a small chamber 20 is provided between the outside air introduction pipe 201 and the fan 206.
3 are provided. The small chamber 203 is provided in the second passage 42
And the sectional area of the second passage 42 is greatly expanded in the small chamber portion. On the other hand, small room 203
Is provided, the cross-sectional area of the first passage 12 is reduced. A small hole 204 (outside air introduction means) is provided in the partition plate 8 that partitions the small chamber 203.

In the present embodiment, an indoor air inlet 220 (indoor air introducing means) opened in the upper panel 4 is provided. The indoor air inlet 220 opens in an upper region of the air-conditioning target region as described later. The indoor air inlet 220 communicates with the indoor air inlet passage 222,
A fan 221 is provided in the indoor air introduction passage 222. Further, the indoor air introduction passage 222 communicates with the indoor air discharge pipe 223. This indoor air discharge pipe 2
The 23 outlets 224 open into the exhaust pipe 210.

Hereinafter, the operation of the present embodiment will be described. In the present air conditioner 200, similarly to the first embodiment, the air-conditioning target area indicated by reference numeral 261 is the room 2
It is between the floor 254 and the boundary 264 located at the height of the upper end of the air inlet 11 from the air conditioning area. That is, warm air is circulated during heating and cool air is circulated in the air conditioning target area 261 during cooling.

When the air conditioner 200 starts operating, the outside air is introduced from the outside air introduction pipe 201 and exhausted by the exhaust pipe 210, so that the third and fourth radiators 23A, 23A
3B of exhaust heat is performed. At this time, since the cross-sectional area of the second passage 42 is expanded in the small chamber 203, the flow velocity of the outside air is extremely low.

On the other hand, since the sectional area of the first passage 12 is reduced at the position where the small chamber 203 is provided, the flow rate of the room air introduced into the first passage 12 is extremely high. Therefore, a negative pressure is generated in the small hole 204,
Outside air (fresh air) is sucked into the first passage 12 through the small hole 204. The amount of outside air flowing into the room can be adjusted by the size of the small hole 204, but basically, the amount of fresh air flowing into the room is smaller than the amount of room air flowing into the first passage 12.

When the fan 221 operates, the room air in the non-management area 262 is sucked from the room air inlet 220. Normally, contaminated air such as cigarette smoke stays in the non-management area 262. The contaminated air pumped by the fan 221 is discharged through the indoor air discharge pipe 223 to the discharge port 22.
4 is discharged into the exhaust pipe 210. The fan 221
By controlling the rotation speed of the above, the amount of contaminated air taken out is controlled to be substantially equal to the amount of inflow of fresh air.

In this embodiment, the non-management area 26
Only the two contaminated air can be efficiently discharged outside the room. In addition, since the discharge of the contaminated air utilizes the circulation of the outside air in the second passage 42, it is not necessary to provide a fan or the like for discharging the contaminated air separately from the present air conditioner. In the case of a general house having low airtightness, fresh air naturally flows into the room due to draft (draft) or the like.
It is not always necessary to provide the small holes 204.

Further, when the air conditioner 200 is stopped, a check valve using a solenoid-operated open / close valve or a reed valve is installed in the small hole 204 to prevent outside air from entering the room.
Or the discharge port 224. FIG.
As shown in (2), the exhaust pipe 210 is provided inside the outside air introduction pipe 201 to form a double pipe structure, so that the hole to the wall 254 can be formed at one place. Also in this case, FIG.
As shown in FIG. 8, the indoor air exhaust pipe 223 is connected to the exhaust pipe 210.
Located inside.

The air conditioner 200 includes a plate heater 207 provided inside the second passage 42 and a radiator 208 provided on the surface of the heater. The plate heater 207 heats the outside air by energizing when the outside air temperature is extremely low at the time of heating, prevents the third and fourth radiators 23A and 23B from abnormally lowering the temperature and prevents the Peltier element from being heated. This ensures stable operation.
In addition, when the water level in the evaporating tank 80 rises above a predetermined water level during cooling and dehumidification, electricity is supplied to increase the temperature of the introduced outside air and promote evaporation of dew condensation water.

Next, a third embodiment will be described with reference to FIG. In the third embodiment, the heat of the air conditioner of the first embodiment is exhausted outside the room using a liquid heat medium. It should be noted that reference numerals for members that perform the same functions as those in the first embodiment are indicated by the same numbers.

In the air conditioner 300, an aluminum liquid tank 302A is used instead of the third radiator 23A used in the first embodiment, and an aluminum liquid tank is used instead of the fourth radiator 23B. Liquid tank 302B is used. This liquid tank 30
General radiator water circulates through 2A and 302B to exhaust heat of the Peltier device. Note that the liquid tanks 302A, 30A
Back side space 30 of the present air conditioner in which 2B is accommodated
1 is filled with a heat insulating material to prevent dew condensation around the tank.

The circulation path and members of the radiator water of the air conditioner 300 will be described starting from the liquid tank 302A. The radiator water flows into the liquid tank 302B from the liquid tank 302A via the pipe 303, and reaches the coupling valve units 321 and 322 from the liquid tank 302B via the pipe 320. This indoor side connection valve 3
21 and the wall-side connection valve 322 are manually operable opening / closing valves, and the connection is manually connectable / disconnectable. That is, the indoor side coupling valve 3
When withdrawing 21 from the wall-side connection valve 322, the withdrawal operation is performed after closing both valves. In addition, these valves are provided with a configuration in which connection / disconnection operations cannot be performed unless they are closed, thereby preventing accidental leakage of radiator water.

The radiator water that has passed through the valve units 321 and 322 passes through a branching unit (branching means) 360, further passes through a pipe 361, and passes through a spare tank 370.
Flows into The spare tank is provided with a heater 371 for heating the radiator water and a water temperature sensor 373.

The radiator water in the spare tank 370 is sucked up from the pipe 372 by the pump P1 and reaches the radiator 380 via the pipe 374. The radiator 380 has a fan 3 rotated by a motor 381.
82 are provided.

The radiator water of the radiator 380 reaches the branch unit 360 via the pipe 383, the pump P2, and the pipe 362, and further reaches the tank 302A via the pipe 310. The pipe 310 is provided with coupling valve units 311 and 312 having the same configuration as the coupling valve units 321 and 322.
It should be noted that the branching unit 360 is provided with two pairs of pipes for sending / inflow of radiator water, which are indicated by reference numerals 340 and 350, respectively. With these pipes, two more air conditioners can be connected in parallel.

On the other hand, the drain pipes 33 and 37 are connected to the connecting pipe 334.
Is connected to the pipe 330 via the. This pipe 3
30 is also provided with coupling valve units 331 and 332 having the same configuration as the coupling valve units 321 and 322.
From 33, it is discharged outside.

The operation of this embodiment is substantially the same as that of the first embodiment. However, the heater 371 heats the radiator water by heating when the water temperature of the radiator water is extremely low during heating, so that the liquid tank 3
It is intended to prevent abnormal temperature drop of 02A and 302B and secure stable operation of the Peltier element. It is also used to prevent radiator water from freezing due to a drop in outside air temperature. These pieces of water temperature information are acquired from the water temperature sensor 373.

In the present embodiment, it is possible to move or expand an indoor air conditioner without requiring any special tools or working experience. If the above-mentioned wall-side coupling unit is provided on the wall surface of each room, corridor, toilet, washroom, etc. of the building, the air conditioner can be installed as necessary without performing installation work.

Furthermore, if a plurality of wall-side coupling units are provided in each room, the air conditioner can be easily moved in response to a change in the arrangement of furniture. Further, as another embodiment, by providing a coupling unit for expansion in the present air conditioner, it is possible to further arrange another air conditioner in parallel, and it is possible to easily increase the air conditioning capacity. . In this case, the additional connecting unit is preferably provided on a side surface of the present air conditioner.

This means that when designing an air conditioner, only air conditioners having a relatively small air conditioning capacity are provided to the market, and can be applied to all air conditioning target areas having various volumes. . That is, it is possible to provide sufficient air-conditioning capacity without excess or deficiency by appropriately changing the number such as one for a toilet, two for a small room, and four for a living room. Such unification of the air conditioning capacity not only achieves a reduction in the manufacturing cost of the air conditioner, but also can be adapted to the demand for an increase or decrease in the air conditioning capacity caused by moving, extension or remodeling. No need to replace equipment.

In each of the above embodiments, the cooling, dehumidifying, and heating functions are realized by a single device. However, originally, the cooling, dehumidifying, and heating devices are single-functioned. It is possible. Further, the forms of the apparatus main body and the members thereof in each of the above embodiments are merely examples, and various other forms can be selected.
