More specifically, when two types of metal are connected in a ring shape, one contact is made high temperature and the other is made low temperature, current occurs in the metal circuit.

The electromotive force generated by the Seebeck effect is proportional to the temperature difference between the two contacts. The magnitude of the thermal current depends on the type of metal paired and the temperature difference between the two contacts, and the electrical resistance of the metal wire is also involved in the magnitude of the thermal current.

On the other hand, the Peltier cooling module is a Peltier effect (Peltier effect, thermoelectric effect) is applied to the current flowing through the phenomenon that the difference in temperature at both ends of the various layers of the conductive material to take advantage of the high temperature of the other side that requires low temperature cooling When the part is forcedly cooled, the heat of the low temperature portion is transferred to the high temperature side. The Seebeck effect makes one side cool and the other hot. Cooling the hot side well improves efficiency, and if overheated, the efficiency decreases and the air is destroyed.

The Peltier cooling module of the present invention includes a heat dissipation unit 301 for heat dissipation, a cooling unit 302 formed on the rear surface of the heat dissipation unit 301, and a cooling fin 303 formed on the cooling unit.

The indoor air is cooled and is configured to include a cooling air inlet 105 circulated into the room.

In addition, the thermocouple and the Peltier cooling module of the solar heat collection module is configured to be electrically connected or cut off, in winter the Peltier cooling module is not electrically operated from the thermocouple 50, the Peltier cooling module in summer It is electrically connected from the thermocouple 50 and cooled by the thermal current generated from the thermocouple of the solar heat collecting module.

In addition, the heat dissipation fins 202 formed on the rear surface of the solar heat collecting plate are preferably formed on the heat dissipating plate attached to the rear surface of the solar heat collecting plate by a heat conductive adhesive.

In particular, referring to FIG. 4, the heat dissipation fins of the solar heat collecting module and the cooling fins of the Peltier cooling module are formed in a zigzag shape in the air flow direction, respectively, to be configured to expand contact with air.

On the other hand, it will be described with reference to Figure 2 the operation of the building exterior wall-type solar collector air conditioning system of the present invention. First, in winter, when the automatic block blower 404 of the external air inlet 106 is operated, the external air is introduced through the external air inlet 106 and heated while passing through the heat dissipation plate front flow path through the heat dissipation fins 202. , Is introduced into the heating air inlet 103 to heat the room.

On the other hand, in summer, when the automatic block blower 402 of the indoor air inlet 104 into which indoor air is introduced, indoor air is introduced through the indoor air inlet 104 to pass through the cooling fins 303 of the Peltier cooling module cooling unit.
