And the generator 40 is to produce electricity by using the rotation of the turbine. In addition, the generator 40 supplies electricity to the thermoelectric module 30 to be described later, and the thermoelectric module 30 heat-exchanges the refrigerant flowing through the refrigerant pipe 90.

Thus, as time passes, the temperature of the heat absorbing portion drops and the temperature of the heat generating portion increases. Use the effect. Therefore, compared with other electric cooler, it is possible to be smaller and lighter.

In this case, the produced electricity operates the thermoelectric module 30 through the switch 42. Therefore, the cooling part 31 of the thermoelectric module 30 becomes low temperature. Therefore, the refrigerant condensed in the outdoor heat exchanger 100 is cooled by the cooling unit 31 of the thermoelectric module 30 while passing through the refrigerant pipe 90 to secure the supercooling degree of the refrigerant. The supercooled refrigerant flows into the indoor unit 10, expands in the indoor expansion valve 4, and then evaporates in the indoor heat exchanger 2.

Referring to Fig. 2, the flow of the refrigerant during the heating operation of the air conditioner of this embodiment will be described.

In the heating operation, the refrigerant evaporates while exchanging heat with the outdoor air in the outdoor heat exchanger (100). The liquid refrigerant is separated from the gas-liquid separator 71 through the four-way valve 60. The refrigerant in the gas phase is compressed in the compressor 70 and then condensed in the indoor heat exchanger 2.

On the other hand, the control unit (not shown) during the heating operation of the air conditioner shuts off the switch 42. Therefore, the electricity produced by the generator 40 is not transmitted to the thermoelectric module 30, and the cooling unit 31 of the thermoelectric module 30 is not cooled. Therefore, the refrigerant condensed in the indoor heat exchanger 2 is not cooled while passing through the refrigerant pipe 90, is expanded in the outdoor expansion valve 80, and then evaporated in the outdoor heat exchanger 100 again.

That is, it can be located in various ways depending on the shape of the heating pipe 92, it is located adjacent to the heating pipe 92 can cool the refrigerant by convection. And to facilitate convection may be provided with a separate blowing fan (not shown). In addition, it may be installed while contacting the heating pipe 92 directly to heat exchange the refrigerant by conduction.

The cooling pipe 91 is provided with a first valve 91a for opening and closing the cooling pipe 91, and the heating pipe 92 is provided with a second valve 92a for opening and closing the heating pipe 92. In the present embodiment, the second valve 92a is closed and the first valve 91a is opened during the cooling operation of the air conditioner, and the first valve 91a is closed during the heating operation of the air conditioner. It further comprises a control unit (not shown) for opening the two valve (92a).

In this embodiment, a switch is not installed between the generator 40 and the thermoelectric module 30. Therefore, unlike the first embodiment, the generator 40 supplies electricity to the thermoelectric module 30 regardless of cooling or heating operation of the air conditioner. As a result, when the air conditioner operates, the cooling unit 31 of the thermoelectric module 30 is cooled regardless of cooling and heating operation, and the heat radiating unit 35 radiates heat. That is, the cooling unit 31 always cools the cooling pipe 91, and the heat dissipation unit 35 heats the heating pipe 92.

Referring to Figure 3, the flow of the refrigerant during the cooling operation of the air conditioner of the present embodiment and the heat exchange process with the thermoelectric module 30 will be described.

In the cooling operation, the controller (not shown) opens the first valve 91a of the cooling pipe 91 and closes the second valve 92a of the heating pipe 92. Therefore, the refrigerant condensed in the outdoor heat exchanger 100 flows into the cooling pipe 91 of the refrigerant pipe 90, and passes through the cooling pipe 91 by the cooling unit 31 of the thermoelectric module 30. Cooling is achieved. Therefore, it is possible to ensure the supercooling degree of the refrigerant during the cooling operation.

4, the flow of the refrigerant and the heat exchange process with the thermoelectric module 30 during the heating operation of the air conditioner of the present embodiment will be described.

During the heating operation, the controller (not shown) closes the first valve 91a of the cooling pipe 91 and opens the second valve 92a of the heating pipe 92. Therefore, the refrigerant passing through the indoor heat exchanger 2 flows into the outdoor heat exchanger 100 while passing through the heating pipe 92. The refrigerant is heated by the heat radiating part 35 of the thermoelectric module 30 while passing through the heating pipe 92. That is, the radiator 35 serves as a heater for heating the refrigerant during the heating operation of the air conditioner. Therefore, even when the outdoor temperature is low during the heating operation, the refrigerant is easily evaporated in the outdoor heat exchanger 100.

In this embodiment, the pole switching switch 42 'is installed between the generator 40 and the thermoelectric module 30. The pole switching switch 42 ′ is a device for switching the pole of electricity flowing into the thermoelectric module 30. When the poles of electricity flowing into the thermoelectric semiconductors 33 of the thermoelectric module 30 are switched, the cooling unit 31 in the first embodiment radiates heat, and the radiating unit 35 is cooled.

Therefore, the thermoelectric module 30 of the present embodiment includes a heat exchanger 31 for heat exchange with the refrigerant pipe 90. That is, the heat exchange part 31 has the same configuration as the cooling part of the first embodiment, but cools or heats the refrigerant flowing through the refrigerant pipe 90 while being cooled or radiated by the operation of the pole change switch 42 '. .

In addition, the controller (not shown) in the present embodiment has a pole switching switch 42 'such that the heat exchanger 31 is cooled during the cooling operation of the air conditioner and the heat exchanger 31 radiates the heat during the heating operation of the air conditioner. ).
