The thermoelectric temperature controller 9 has a structure in which a large number of thermoelectric elements are integrated. One electrode of each thermoelectric element faces the air conditioning passage 4 and the other electrode faces the outside air passage 5. are doing. An air-conditioning fan 10 is provided at an inlet of the air-conditioning passage 4 of the housing 6, and air sucked from one side of the air-conditioning passage 4 passes through an adsorption-type humidity controller 7, a heat exchanger 8, and a thermoelectric temperature controller 9, and the other side. To be discharged to A humidifier 11 is disposed at the outlet of the air conditioning passage 4.

The hybrid solar panel 2 comprises a plate-shaped solar cell 16 and a solar collector 17 provided on the back side of the solar cell 16, and these are installed on the upper surface of the roof B. The solar collector 17 comprises a cavity 18 along the back side of the solar cell 16 and an outside air suction fan 19 for sucking air from outside air into the cavity 18. The cavity 18 of the solar collector 17 includes a duct 20 and a switching unit 21.
Through the outside air introduction duct 1 of the hybrid air conditioner 1
3 is connected. The switching section 21 is configured to allow a part or all of the heated air from the solar collector 17 to flow into the room A as necessary. The solar cell 16 is connected to a thermoelectric element of the thermoelectric thermostat 9 of the hybrid air conditioner 1. This thermoelectric element is also connected to a commercial power supply.

The operation of the above configuration will be described. Room A
The high-temperature, high-humidity air sucked into the air-conditioning passage 4 is first desorbed by the adsorption-type humidity controller 7 to reduce its absolute temperature. The dehumidifying action at this time is performed by an adsorbent such as silica gel. Therefore, the latent heat is released by the water condensation at this time, and the temperature of the air exiting the air conditioning passage 4 of the adsorption type humidity controller 7 rises from the suction port side.

At this time, although the water absorbing capacity of the adsorbent in the portion of the adsorption type humidity controller 7 facing the air conditioning passage 4 gradually deteriorates due to the adsorption of moisture, the adsorption dehumidifier 7 is gradually rotating. As a result, the deteriorated portion is gradually replaced with a portion facing the outside air passage 5 side, and is sequentially reproduced.

The dehumidified air in the adsorption type humidity controller 7 causes the temperature of the air-conditioned air whose temperature has risen to be exchanged with the temperature of the outside air in the heat exchanger 8 to be lowered. Accordingly, the relative humidity of the conditioned air at this time increases. The absolute humidity at this time does not change.

Next, the temperature is adjusted to a predetermined temperature by the thermoelectric temperature controller 9 and the temperature is again discharged into the room A. At this time, the air-conditioning passage 4 side of the thermoelectric temperature controller 9 is on the cooling side, and by passing therethrough, the conditioned heat of the conditioned air is absorbed and cooled. This cooling temperature is accurately controlled by controlling the amount of electricity supplied to the thermoelectric element. This electric power is used from the solar cell 16 of the hybrid solar panel 2.

The outdoor air or the air from the solar collector 17 of the hybrid solar panel 2 flows into the outside air passage 5 during switching of the air conditioner by switching the switches 12a, 12b, and 12c. The adsorption section of the humidity controller 7 is dried and regenerated. At this time, if necessary, an electric heater 22 is provided upstream of the outside air passage 5 of the adsorption type humidity controller 7.
To heat the intake air outside. By using the heated air from the hybrid solar panel 2 as the regeneration outside air of the adsorption type humidity controller 7, a sufficient amount of heat can be used without using the electric heater 22.

Each of the temperature and the humidity is measured by a temperature measuring unit and a humidity measuring unit (both not shown).

The indoor set temperature T ₅ and humidity H ₅ are compared with the indoor temperature T ₄ and humidity H ₄ . In this case, 4 shown in Table 5
There are two cases. The control method differs depending on each case.

_The controller 23 controls the rotation speed of the fan so that the temperature of the fan ₃ reaches the set temperature, for example, 60 ° C. In the case where the temperature becomes 60 ° C. or more, the rotation speed of the fan 19 is increased to keep the temperatures of T ₂ and T ₃ at 60 ° C. By doing so, it is possible to simultaneously prevent a decrease in efficiency due to an increase in the temperature of the solar cell 16 and to improve the efficiency of the adsorption type humidity controller 7 by the heat output from the solar collector 17. The heat output from the solar collector 17 enters the adsorption type humidity controller 7 and is used for dehumidifying indoor air. At this time, the temperature level is important.

(C) Case 3 (Heating and Dehumidifying) Both electric power and heat to the thermoelectric temperature controller 9 and heat to the adsorption type humidity controller 7 are required. Since more heat is required, control is made to take as much heat as possible.
Specifically, when T ₂ becomes equal to or higher than T ₁ + 5 ° C., the fan 19 of the solar collector 17 is turned on. T ₃ is a set temperature, for example, 60
The rotation speed of the fan 19 is controlled so as to reach 60 ° C.
Need not be so press the temperature of the even T ₃ becomes higher. A part of the heat output from the solar collector 17 is given to the thermoelectric temperature controller 9 and the other is given to the heat exchanger 8 and the adsorption type humidity controller 7. Depends on At this time, both the temperature level and the amount of heat are important.

(D) Case 4 (heating and humidification) Electric power and heat to the thermoelectric temperature controller 9 are required, but the heat output requires more heat than the temperature level. Therefore, the temperature level is lowered so that a large amount of heat can be obtained. Specifically, T ₂
When the temperature exceeds T ₁ + 5 ° C, the fan of the solar collector 17 is turned on.
N. T ₃ is a set temperature, for example so as to be 40 ° C. Fan 1
9 is controlled. In the case where the temperature becomes 40 ° C. or more, the rotation speed of the fan 19 is increased to raise the temperature of T ₃ to 40 ° C.
To be able to press. The heat output from the solar collector 17 is
Some are provided to the thermoelectric heater 9 and others to the heat exchanger 8, the proportions of which differ depending on the set temperature and humidity levels. In this case, the amount of heat is important.
