Description

Wet cold and hot air supply device and its operation method {WET COLD AND HOT AIR SUPPLY DEVICE AND OPERATING METHOD OF THE SAME}

The present invention relates to a wet cold and hot air supply apparatus and an operating method thereof, and to a technology of a wet cold and hot air machine having a large sensible effect on temperature.

The air conditioner according to the prior art circulates and repeats four operations of evaporation/compression/condensation/expansion, and requires hardware and installation space such as refrigerant, compressor, electromagnetic clutch, condenser, dryer, expansion valve, evaporator, and blower.

In order to solve this problem, a method of using a thermoelectric element that refers to direct energy conversion between heat and electricity and uses a thermoelectric phenomenon generated by the movement of electrons and holes in the material was used. A thermoelectric element is a generic term for a device using a thermoelectric phenomenon, and has a structure in which a P-type thermoelectric material and an N-type thermoelectric material are bonded between metal electrodes to form a PN junction pair.

Thermoelectric elements are widely applied to home appliances, electronic parts, and communication parts. For example, the thermoelectric element may be applied to an apparatus for cooling, an apparatus for heating, an apparatus for power generation, and the like. Accordingly, the demand for the thermoelectric performance of the thermoelectric device is increasing. Thermoelectric devices can be divided into devices using a temperature change in electrical resistance, devices using the Seebeck effect, which is a phenomenon in which electromotive force is generated by a temperature difference, and devices using the Peltier effect, which is a phenomenon in which heat absorption or heat is generated by current. .

However, the thermoelectric element according to the prior art is mostly used as a cooler in a closed space, a fan blower and a large cooling fin are attached to the heating part, and when the cooling of the heating part is not good, the heat of the heating part is transferred to the cooling part due to a thermoreversal phenomenon The device was damaged by the transition. In addition, in order to cool the heat generating unit in a closed space, the exhaust is exhausted from the heat generating unit to the outside, and it is difficult to configure the device in an open space.

The matters described as the background art above are only for improving the understanding of the background of the present invention, and should not be taken as acknowledging that they correspond to the prior art already known to those of ordinary skill in the art.
