TECHNICAL FIELD The present invention relates to an air conditioner and an air conditioning system including the same.

The present invention relates to an air conditioner that adjusts the temperature and humidity of air using a thermoelectric temperature controller using a thermoelectric element and a humidity controller using a moisture absorbent, and an air conditioning system including the same. Background art

Small dehumidifiers and refrigerators are currently in practical use as devices that control the temperature and humidity of air using only thermoelectric elements. However, in order to dehumidify only by adjusting the temperature, the air must be cooled and the relative humidity in the air must be reduced to 100% to cause dew condensation, so an operation that creates a large temperature difference is required. However, the efficiency of thermoelectric elements becomes worse as the temperature difference increases, and there is a problem that the cost and efficiency are insufficient for application to medium and large dehumidifiers and refrigerators.

On the other hand, an air conditioner that uses a thermoelectric element and a desiccant such as silica gel to control the temperature with the thermoelectric element and to control the humidity with the desiccant has been disclosed in Jpn. This is known from the official gazettes of Jpn.

However, the above-described conventional technology using a thermoelectric element and a desiccant uses a heating / cooling device (thermostat) using a thermoelectric element and a dehumidifier (humidifier) using a desiccant in an apparatus Not only are they separated, but there is no connection in the control functions of temperature control and humidity control. In addition to this, the efficiency of the thermoelectric element is low, and the temperature and humidity of a predetermined amount of air are large and poorly controlled. The problem of becoming a device

In the case of using a compressor to control the temperature and humidity of air, the above problem does not occur. However, even if a substitute for the heat medium is used, the use of a substitute for the environment will not affect the environment in the future. The above problems are inevitable. One object of the present invention, in view of the above-mentioned problems, is to reduce the load on the thermoelectric element in an air conditioner using a thermoelement and a desiccant, and to improve the efficiency of the air conditioner. It is an object of the present invention to provide an air conditioner capable of accurately controlling the temperature and humidity of the air conditioner, and at the same time, reducing the size and cost. Another conventional air conditioner, particularly an air conditioner using a thermoelectric temperature controller, is disclosed in Japanese Unexamined Utility Model Application Publication No. Heisei 2-1-211117 and Japanese Unexamined Patent Publication No. Heisei 5-10543. Are known.

The former of the above-mentioned conventional hybrid air conditioners has a configuration in which a solar cell is used as a power supply for a thermoelectric element of a thermoelectric cooling unit and a power supply for a fan.

In addition, the latter conventional hybrid air conditioner uses a solar cell as a power supply for the thermoelectric element, and supplies air heated by solar heat to the heat absorption side of the thermoelectric element and supplies the air into the living space. To heat it.

In both of the above conventional hybrid air conditioners, the elimination of humidity in the air is performed by lowering the air temperature with a thermoelectric element and condensing the moisture in the air. Therefore, dehumidifier Therefore, a heavy load is imposed on the thermoelectric element, and the thermoelectric element in the current technology cannot withstand this burden due to thermoelectric efficiency and the like. Therefore, the above-mentioned conventional hybrid air conditioner could not actively remove moisture in the air, and could not efficiently perform air conditioning including humidity adjustment.

In view of the above problems, another object of the present invention is to perform air dehumidification without cooling air by an electric temperature controller, and to provide an electric temperature controller for a humidity control function. Load, and the efficiency of the solar cell and humidity controller can be improved, and the hybrid can be operated with high efficiency even in winter. It is intended to provide a head-type air conditioning system. Disclosure of the invention

Further, in the above configuration, a heating source may be arranged on the regeneration passage upstream of the humidity controller.

On the other hand, the humidifier is humidified or dehumidified by the air-conditioning action of the conditioned air passing through the air-conditioning passage, the heat exchanger is cooled or heated, and the thermoelectric heating / cooling device is heated or cooled. Are regenerated by the regeneration air flowing through the regeneration passage.

Therefore, in an air conditioner using a thermoelectric element and a desiccant, the load on the thermoelement can be reduced, the efficiency can be improved, and the outlet temperature can be accurately controlled by a thermoelectric heating / cooling device using the thermoelectric element. Can be controlled. Further, since the air-conditioning passage and the regeneration passage have a body structure, the size and cost of the entire air-conditioning system can be reduced.

Furthermore, according to another aspect of the present invention, there is provided another aspect of the present invention,

In the above configuration, a temperature measuring section for measuring a temperature of the power generation section; A control unit for controlling the operation of the fan may be provided.

Further, in the above configuration, it is desirable to use a thermoelement in the electric temperature controller.

According to the above configuration, in the hybrid air conditioner, the air sucked into the air conditioning passage is humidified by the adsorption type humidifier, and then the temperature is adjusted by the electric temperature controller and flows into the room. On the other hand, in a hybrid solar panel, power is generated by the power generation unit and air heated by the heat collection unit is supplied. The heated air from the heat collecting section is used not only as regeneration air for the adsorption type humidity controller, but also as a heat source for heating (for regeneration) the electric temperature controller. . Further, the power generation unit is used as a power source of an electric temperature controller.

Therefore, in a hybrid air-conditioning system that uses solar cells as the power source for the electric temperature controller and uses the air warmed by the sun, the electric temperature controller controls the dehumidification of the air. This can be performed without the need to cool the air by means of air, and the burden on the electric temperature controller for the humidity control function can be reduced. In particular, this effect is remarkable when a thermoelement is used for an electric temperature controller. In addition, by appropriately controlling the amount of heat and power supplied from the hybrid solar panel, it is possible to improve the efficiency of the solar cell and the humidity controller, and in winter It can be operated with high efficiency.

FIG. 1 shows a schematic configuration of an embodiment of an air conditioner according to the present invention, in which 1 is a humidity controller, 2 is a heat exchanger, and 3 is a thermoelectric heating / cooling device (temperature controlling device). is there. 4 is an air conditioning passage, and 5 is a regeneration passage. The humidity controller 1 has a large number of honeycomb-shaped partitions constituting a ventilation path, and has a configuration in which a hygroscopic agent such as silica gel is applied to the surfaces of the respective brackets. A part of the humidifier 1 is an air-conditioning passage 1a which is a part of the air-conditioning passage 4, and another part is a regeneration passage 1b which is a part of the regeneration passage 5. By making the humidity controller 1 a rotary type, the two passage portions 1a and 1b are sequentially switched.

A specific example of the humidity controller 1 is a rotary dehumidifier that is commercially available as a dehumidifier rotor.

A part of the heat exchanger 2 is an air-conditioning passage 2 a that is a part of the air-conditioning passage 4, and another part is a regeneration passage 2 b that is a part of the regeneration passage 5.

Specific examples of the heat exchanger 2 include a conventionally known rotary regenerative heat exchanger, a stationary plate heat exchanger, a stationary heat pipe heat exchanger, and the like.

The thermoelectric heating / cooling device 3 has a configuration in which a large number of thermoelectric elements are integrated, and one electrode of each thermoelectric element faces the air conditioning passage 3 a which is a part of the air conditioning passage 4, and the other electrode. These electrodes face the regeneration passage 3b which is a part of the regeneration passage 5.

The air conditioning passage 4 consists of a humidity controller 1, a heat exchanger 2, and a thermoelectric heating / cooling device. The air-conditioning passages la, 2a, and 3a in Fig. 3 are connected in series, and the inlet side is open to the inside or outside of the room, and the outlet side is used to supply conditioned air such as a clean room or living room. It is open to the required room to be conditioned.

The regeneration passage 5 has a configuration in which the regeneration passages 3 b, 2 b, and lb of the thermoelectric heating / cooling device 3, the heat exchanger 2, and the humidity controller 1 are connected in series. It is opposite to the flow direction of the air conditioning passage 4. The entrance side is opened indoors or outdoors, and the exit side is opened indoors or outdoors.

In the regeneration passage 5, an intake / exhaust passage 6 a communicating with another system passage such as indoor or outdoor is connected downstream of the thermoelectric heating / cooling device 3. The regeneration passage 5 has a heat exchange bypass passage 7 that bypasses the heat exchanger 2. The heat exchange bypass passage 7 has an intake / exhaust passage that communicates with another system such as an indoor or outdoor passage. 6 b is connected.

In the regeneration passage 5, a heater 8 for heating the regeneration air entering the regeneration passage 1 b of the humidity controller 1 is provided upstream of the humidity controller 1.

A directional switching valve 9 such as a three-way switching valve is interposed at each connection point between the intake and exhaust passages 6a and 6b, the bypass passage 7, and the regeneration passage 5. The operation of the above embodiment will be described below.

(1) High temperature ♦ High humidity air conditioning

The high-temperature, high-humidity air sucked into the air conditioning passage 4 from the room or outside is first dehumidified in the air conditioning passage 1a of the humidity controller 1 to reduce the absolute humidity. The dehumidifying effect at this time is due to a moisture absorbent such as silica gel. Done. Therefore, the latent heat is released by the condensation of water at this time, and the temperature of the air exiting the air conditioning passage 1a of the humidity controller 1 rises more than at the time of inhalation.

The moisture absorbent in the air conditioning passage 1a of the humidifier 1 gradually deteriorates due to moisture absorption, but when a rotary dehumidifier is used for the humidifier 1, the air conditioning passage facing the air conditioning passage 1 is used. 1 a gradually replaces the regeneration passage 1 b facing the regeneration passage 5, and the desiccant is regenerated sequentially as it approaches the regeneration passage 5. The conditioned air whose temperature has risen due to dehumidification in the air conditioning passage la of the humidity controller 1 is cooled to a temperature close to the required temperature in the air conditioning passage 2 a of the heat exchanger 2. You. Accordingly, the relative humidity of the air-conditioned air at that time rises. The absolute humidity at this time does not change.

Next, the conditioned air is adjusted to a predetermined temperature in the air conditioning passage 3 a of the thermoelectric heating / cooling device 3.

At this time, the air conditioning passage 3a of the thermoelectric heating / cooling device 3 is on the cooling side, and the conditioned air is cooled by absorbing the sensible heat as it passes through it. Then, the cooling temperature at this time is accurately controlled by controlling the amount of electricity to the thermoelectric element.

Next, the operation of the regeneration passage 5 on the air conditioning passage 4 will be described. The heat in the regeneration passage 3b of the thermoelectric heating and cooling device 3 is taken away by the regeneration air passing through the regeneration passage 5, and the heat absorbed in the air conditioning passage 3a is released from the regeneration passage 3b. .

Similarly, the heat of the regeneration passage 2b of the heat exchanger 2 is taken away, and the heat absorbed in the air conditioning passage 2a is released from the regeneration passage 2b. Regeneration of the regeneration passage 3b of the thermoelectric heating / cooling unit 3 and regeneration of the heat exchanger 2 While passing through the passage 2b, the regenerated air whose temperature has risen by absorbing heat from them is further heated by the heater 8, passes through the regeneration passage 1b of the humidity controller 1, and passes through the air conditioning passage. After absorbing moisture in section 1a, the desiccant that has entered regeneration passage section 1 is dried and regenerated.

The passage of the regeneration air at this time is generally a system in which the regeneration passages 3b, 2b, and lb of the thermoelectric heating / cooling unit 3, heat exchanger 2, and humidity controller 1 are connected in series. Depending on the relationship between the temperature of the regeneration air and the temperatures of the regeneration passages 3 b and 2 b of the thermoelectric heating / cooling device 3 and heat exchanger 2, as shown in FIG. The regeneration passage 2b of the exchanger 2 may be bypassed, or as shown in Fig. 3, separate regeneration air may be used for the regeneration passage 3b of the thermoelectric heating / cooling device 3 and its downstream side. As shown in Fig. 4, separate regeneration air is used for the regeneration passage 3b of the thermoelectric heating / cooling unit 3 and its downstream side, and another system is located downstream of the regeneration passage 2b of the heat exchanger 2. May be allowed to flow in.

In the above embodiment, the heat exchanger 2 is used.However, when the absolute humidity is relatively low, the same effect can be obtained with an air conditioner including only the humidity controller 1 and the thermoelectric heating / cooling device 3. .

The transition of the temperature and humidity of the conditioned air in the air conditioning passage 4 will be described with reference to the psychrometric chart of FIG.

For example, to obtain the final conditioned air at a temperature of 26 and a humidity of 55% (relative humidity, the same applies hereinafter), the absolute humidity of the conditioned air at this time is 0.011 kg / kg (humidity of dry air).

Now, when the inlet temperature of the air to be air-conditioned is 33 and the inlet humidity is 63% (point A), the absolute humidity of the air-conditioned air in the air-conditioning passage 1a of the humidity controller 1 is 0.01 15 kg / kg (dry air humidity) Dehumidify until dry. In this case, the temperature rises due to the release of latent heat due to moisture coagulation that occurs with the dehumidifying action. Then, the temperature and humidity in this case change along the isoenthalpy line to the absolute humidity 0.01 15 kg / kg (dry air humidity:> point B) where the temperature changes. 5 The humidity is about 10%.

Next, in the heat exchanger 2, the temperature in the dehumidified state is cooled to, for example, 38 ° C. so as to approach the temperature of the final conditioned air of 26 ° C. As a result, the humidity of the conditioned air at this time becomes 28% (: C point).

The conditioned air is further cooled to a predetermined 26 by the thermoelectric heating / cooling device 3, and the humidity at this time becomes 55% (point D).

According to the above operation, the temperature difference between the air at the outlet of the heat exchanger 2 and the final conditioned air is 12 ° C. The thermoelectric element does not change the absolute humidity, and the temperature is only 38 ° C to 26 ° C. With C, the amount of movement of the enthalbi during that time is only 1.6 + 1.3 = 2.9 kca 1 / kg as shown in FIG.

For comparison with the above embodiment, a case of performing dehumidification cooling only by a thermoelectric element, which is a conventional technique, with reference to FIG. 5 will be described as follows.

In order to dehumidify air with a temperature of 33 and a humidity of 63%, it is necessary to cool it down to a humidity of 100% and dehumidify it by condensation as shown by the dotted line in the figure. . Therefore, it is necessary to cool the air down to 16% before the humidity reaches 55%.

Thus, to convert air with a humidity of 63% to air with a humidity of 55%, that is, to convert air with a temperature of 33 into air with a temperature of 16 ° C, 9. A transfer of 5 kca 1 / kg enthalbi is required.

In addition, air that has been cooled to 16 ° C and dehumidified is then heated to the desired temperature of 26 and requires additional heat transfer.

(2) Low temperature and low humidity air conditioning

If the temperature and humidity at the inlet side of the air to be conditioned are lower than those of the final conditioned air, first humidify the air in the humidifier 1 and then heat exchanger 2 to a temperature close to the temperature of the final conditioned air. , And finally heated to a predetermined temperature by the thermoelectric heating / cooling device 3.

6 to 8 show specific examples of the air conditioner according to the present invention. In the first specific example shown in FIG. 6, a rotary dehumidifier 10 is used as the humidity controller 1, and a rotary heat exchanger 11 is used as the heat exchanger 2.

Similarly, the second specific example shown in FIG. 7 uses a stationary plate type heat exchanger 12 as the heat exchanger 2. In the third specific example shown in FIG. 8, a fixed heat pipe type heat exchanger 13 is used as the heat exchanger 2.

FIG. 9 shows a first application example in which an air conditioner 14 as the first specific example is used in a house, which is used for indoor cooling and heating by embedding the air conditioner 14 in a wall 15. It is used.

FIGS. 10 and 11 show second and third application examples, respectively, in which the first specific example is used for indoor cooling and heating.

In the second application example shown in FIG. 10, the inlet side and the outlet side of the air conditioning passage 4 are both open to the room. Then, outside air is taken into the regeneration passage 3b of the thermoelectric heating / cooling device 3, which cools it and discharges it to the outside again. 06311

-13- In addition, another outdoor air is taken into the regeneration passage sections 2b and 1b of the rotary heat exchanger 2 and the rotary humidity controller 1 from the upstream side of the heat exchanger 2, and the outdoor air is returned to the outdoor again. Release.

The third application example shown in FIG. 11 is the one shown in FIG. 10 described above, in which an air inlet is also provided on the upstream side of the regeneration passage 1 b of the humidity controller 1.

That is, outside air intakes 15a, 15b, 15 are located upstream of the regeneration passages 3b, 2b, and lb of the thermoelectric heating / cooling unit 3, the heat exchanger 2, and the humidity controller 1, respectively. c is provided. Each of the outside air intakes 15a, 15b, 15c is connected to a solar collector via a switchgear 16a, 16b, 16c. 17 and the outside air inlets 15a and 15b of both the thermoelectric heating / cooling unit 3 and the heat exchanger 2 are connected to the ducts by the open / close plates 16a and 16b. Note _c sheet 1 7 side outside air inlet 1 8 and is communicating and blocking alternately a, 1 8 b are connected, each closing plate 1 6 a, 1 6 b, 1 6 c are shorted with a temperature-off An operative shape memory alloy may be used.

In the third application example shown in Fig. 11, the open / close position of each open / close plate 16a, 16b, 16c is changed depending on whether it is hot in summer or cold in winter. It is like that.

That is, when it is hot in summer, outside air is supplied to the thermoelectric heating / cooling unit 3 and the heat exchanger 2, and hot air from the solar collector is supplied to the humidity controller 1 from the duct 17.

Also, when the temperature is cold in winter, warm air from the solar collector is put into the thermoelectric heating / cooling unit 3 and the heat exchanger 2, and the inlet of the humidity controller 1 is closed. In each of the above examples, the humidifier 1 is a rotary type and uses a moisture absorbent such as silica gel, but as another example, the humidifier 1 is used. Some use a membrane module configuration. FIG. 12 shows a specific example of the humidity controller 1, in which a number of hollow fiber membranes 20 are arranged between upper and lower headers 19a and 19b. A moisture-absorbing fluid or a regeneration fluid is caused to flow through the hollow fiber membrane 20, and conditioned air is caused to flow outside the hollow fiber membrane 20. Then, the conditioned air flowing outside the hollow fiber membrane 20 is dehumidified or humidified by the moisture absorbing or regenerating fluid flowing through the hollow fiber membrane 20 via the hollow fiber membrane 20. It has become.

FIG. 13 shows an embodiment of an air conditioning system in which the third application example is actually incorporated in a house.

In the figure, 101 is a hybrid air conditioner and 102 is a hybrid solar panel.

The adsorption-type humidity controller 107 and the heat exchanger 108 Each of the air conditioning passages and the regeneration passages is also formed in a rotating cylindrical shape supported by the partition wall 103 so that the air conditioning passages and the regeneration passages are sequentially rotated. Has come to be replaced.

The thermoelectric thermostat 109 has a configuration in which a large number of thermoelectric elements are integrated. One electrode of each thermoelectric element faces the air-conditioning passage 104, and the other electrode is a regeneration passage 109. We are facing 5.

An air-conditioning fan 110 is provided at the inlet of the air-conditioning passageway 104 of the housing 106 so that the air sucked from one end of the air-conditioning passageway 104 can absorb the air of the adsorption-type humidifier 1. The air is discharged to the other end of the air conditioning passageway 104 through the heat exchanger 107, the heat exchanger 108, and the thermoelectric temperature controller 109. A humidifier 111 is disposed at the outlet of the other end of the air conditioning passage 104.

The regeneration passage 105 has a first regeneration passage 105a through which air flows outdoor through the adsorption type humidity controller 107, and air adsorbs to the heat exchanger 108. A second regeneration passageway 105b, which flows outside through a humidity controller 107, and a second passageway, which allows air to flow outside through a thermoelectric temperature controller 109. It consists of 3 regeneration passages 1 0 5 c and.

The first, second, and third regeneration passages 105a, 105b, and 105c are independent opening / closing valves 112a, 112, respectively. It is connected to the outside air introduction duct 113 via b and 112c.

The open / close valves 112, 112c of the second and third regeneration passages 105b, 105c are connected to the outside air introduction duct 113, and the duct 114 connected to the outside. a, any outside air introduction duct 1 1 3 Each of the passed ducts 1 1 and 4b is selectively opened.

At the outlets of the first and third regeneration passages 105a and 105c, blow-out fans 115a and 115b are disposed, respectively.

The hybrid solar panel 102 consists of a plate-like solar cell 1 16 and a solar collector 1 17 provided on the back side of the solar cell 1 16 and these are installed on the top surface of the roof RF. Have been.

The solar collector 1 17 is composed of a cavity 1 18 along the back of the solar cell 1 16 and an outside air suction fan 1 19 that sucks outside air into the cavity 1 18. I have. The number of revolutions of the fan 1 19 is controlled by the control device 1 23. Then, the cavities 1 18 of the solar collector 1 17 are introduced into the outside air of the hybrid air conditioner 101 via the ducts 120 and the switching section 121. Connected to ducts 1 1 and 3. The switching section 121 is configured so that a part or all of the heated air from the solar collector 117 can flow into the room A as needed.

The solar cell 116 is connected to a thermoelectric element of a thermoelectric thermostat 109 of the hybrid air conditioner 101. This thermoelectric element is also connected to a commercial power supply.

Next, the operation of the air conditioning system will be described.

High-temperature, high-humidity air drawn into the air-conditioning passage 104 from the indoor RM is first dehumidified by the adsorption-type humidity controller 107 to reduce the absolute temperature. Latent heat is released by the water condensation at this time due to the adsorbent, and the temperature of the air exiting the air conditioning passage of the adsorption type humidity controller 107 rises from the suction port side. I do.

At this time, the water absorption capacity of the adsorbent in the portion of the adsorption type humidity controller 107 facing the air conditioning passage 104 gradually deteriorates due to the adsorption of moisture, but the adsorption and dehumidification device 107 gradually reduces the water absorption capacity. Due to this rotation, the deteriorated portion gradually replaces the portion facing the regeneration passage 105 side, and is sequentially reproduced.

The air-conditioned air whose temperature has risen by being dehumidified by the adsorption-type humidity controller 107 is exchanged with outside air in the heat exchanger 108 to be cooled. The relative humidity of the conditioned air at the time increases. The absolute humidity at this time does not change.

Next, the conditioned air is adjusted to a predetermined temperature by a thermoelectric temperature controller 109 and discharged again into the room RM.

At this time, the air conditioning passage 104 side of the thermoelectric temperature controller 109 is on the cooling side, and by passing through it, the conditioned air absorbs its sensible heat and is cooled. You. Then, the cooling temperature at this time is accurately controlled by controlling the amount of electricity to the thermoelectric element. The power for this is from the solar cells 1 16 of the hybrid solar panel 102.

The outdoor air or the solar collector 110 of the hybrid solar panel 102 is switched to the regeneration passage 105 during the air-conditioning operation by switching the selectors 112a, 112b and 112c. The air from 7 flows in, and the adsorbing section of the adsorption type humidity controller 107 is dried and reproduced by the inflowing air. In this case, if necessary, an electric heater 122 is interposed on the upstream side of the regeneration passage 105 of the adsorption type humidity controller 107 to heat the intake air. The heater 122 is used by using the heated air from the hybrid solar panel 102 as the outside air for regeneration of the adsorption type humidity controller i07. Sufficient heat can be used to heat the intake air.

The case is shown. In addition, the strength of the operation of the solar heater refers to an operation state in which the operation of the outside air intake fan 119 is controlled to capture a large amount of solar heat or a small amount of solar heat.

Now, let T1 be the temperature of the outside air, T2 be the temperature on the back side of the solar cell 116, and T3 be the temperature of the air from the solar collector 117 that is introduced into the hybrid air conditioner 101. The indoor temperature is set to Τ4, the indoor humidity is set to Η4, the indoor set temperature is set to Τ5, the indoor set humidity is set to Η5, and the set temperature of the solar cell 116 is set to Τ6. Each of the temperature and the humidity is measured by a temperature measuring unit and a humidity measuring unit (both not shown).

First, the indoor set temperature Τ5 and the set humidity Η5 are compared with the indoor temperature Τ4 and the humidity Η4. In this case, consider the four cases shown in Table 5 below. The control method differs depending on the case

• Basic principles of control

This air conditioning system is a system that independently controls temperature control and humidity control.That is, group I in Table 5 above is a part related to temperature control, and is controlled by a thermoelectric temperature controller 109. Group II is a part related to humidity control, and is controlled by the adsorption type humidity controller 107, heat exchanger 108, and heater 111.

The thermoelectric temperature controller 109 is driven by electricity, but the output from the solar cell 116 is used preferentially, and in the case of insufficient power from the commercial power supply. Also, the regeneration of the moisture absorption part of the adsorption type humidity controller 107 is performed by heating, but the heat output from the solar collector 117 is used preferentially. Use an electric heater that generates more heat.

• Specific control method

In the following, the hybrid blind solar cell in each case

The control method when 102 is used will be described. () Case 1 (cooling, dehumidification)

In this case, both the electrical output from the solar cell 1 16 and the heat output from the solar collector 1 17 are required, so both the solar cell 1 16 and the solar collector 1 17 are required. Control so that the output increases as much as possible. Specifically, when T 2 becomes T 1 + 10 ° C or more, the fan 1 19 of the solar collector 1 17 is turned on, and T 3 reaches its set temperature, for example, 60. The rotation speed of fan 1 19 is controlled by controller 1 2 3. If T2 and T3 exceed 60, increase the rotation speed of fan 119 so that T2 and T3 can be suppressed to 60 ^: C. . As a result, the efficiency of the solar cell 1 16 is prevented from lowering due to the high temperature, and the efficiency of the adsorption type humidity controller 1 107 is increased by the heat output from the solar collector 1 17. Can be improved at the same time. The heat output from the solar collector 117 enters the adsorption type humidity controller 107 and is used for dehumidifying indoor air. At this time, the temperature level is important.

(b) Case 2 (cooling, humidification)

In this case, power to the thermoelectric thermostat 109 is required, but heat to the adsorption humidity controller 107 is unnecessary, so the output from the solar cell 116 is maximized. In such a manner, the rotation speed of the fan 1 19 is increased by the controller 1 23 so that T 2 becomes equal to or less than T 1 +5.

(c) Case 3 (heating, dehumidification)

Although both power to the thermoelectric temperature controller 109 and heat to the adsorption type humidity controller 107 are required, both heating and dehumidification require more heat. Control so as to take in as much heat as possible. More specifically, when T 2 exceeds T 1 +5 ° C, the fan 1 19 of the solar collector 1 17 is set to 0 N. Their to, T 3 is a set temperature, for example, I to 6 0 ^S C The rotation speed of fan 119 is controlled by control device 123 as described above, but it is not necessary to suppress the temperature of T3 even when the temperature exceeds 60 ° C. The heat output from the solar collector 117 is given to the thermoelectric temperature controller 109, and to the heat exchanger 108 and the adsorption humidity controller 107, These percentages depend on the set temperature and humidity levels. At this time, both the temperature level and the amount of heat are important.

(: D) Case 4 (heating, humidification)

The power and heat to the thermoelectric temperature controller 109 are required, but the heat output needs to be more than the temperature level. Therefore, lower the temperature level to get more heat. Specifically, when T 2 becomes Tl + 5 ° C or more, the fan of the solar collector 1 17 is turned ON. Then, the control device 123 controls the number of revolutions of the fan 119 so that −T 3 becomes a set temperature, for example, 40 ° C. If T3 becomes 40 ° C or more, increase the rotation speed of fan 119 so that the temperature of T3 can be kept at 40 ° C. The heat output from the solar collector 117 is given to the thermoelectric heater 109 partly and to the heat exchanger 108 partly.These ratios are the set temperature and humidity. Depends on the level. In this case, the amount of heat is important.

In the above embodiment, a thermoelectric temperature controller 109 using thermoelectric elements is used as an example of an electric temperature controller, but the electric temperature controller is shown in FIG. 14. Alternatively, a compression temperature controller 124 may be used.

This compression-type thermostat 124 uses a normal heat pump, and has an outside air side 125 located on the third regeneration passage 105 c side and an air conditioning passage 104 side. An outdoor unit consisting of a three-way valve 1 2 8, a compressor 1 2 9, an expansion valve 13 0, etc., through a refrigerant pipe 1 2 7 with the indoor side 1 2 6 located Connected to 1 3 1.

As described above, according to the present invention, in an air conditioner using a thermoelectric element and a desiccant, the load on the thermoelectric element can be reduced, the efficiency can be improved, and the outlet temperature can be reduced. It can be controlled accurately by the thermoelectric heating and cooling equipment used. Further, since the air-conditioning passage and the regeneration passage have a body structure, the size and cost of the entire air-conditioning apparatus can be reduced.

Further, according to the present invention, in an air-conditioning system of an bridge type using a solar cell as a power source of an electric temperature controller and using air heated by the sun. In addition, the air can be dehumidified without being cooled by the electric temperature controller, thereby reducing the load of the electric temperature controller on the humidity control function. In particular, the effect is remarkable when a thermoelectric element is used for an electric temperature controller. By appropriately controlling the amount of heat and power supplied from the hybrid solar panel, it is possible to improve the efficiency of the solar cell and the humidity controller, and even in winter. It can be operated with high efficiency.

Is obvious to those skilled in the art. Therefore, the present invention should not be construed as being limited to the above-described embodiments, but as including the scope defined by the elements recited in the claims and their equivalents.
