Heat-pump air conditioner with heat-recovery type ventilation function

The present invention relates to a heat pump air conditioner having a heat recovery type ventilation function, and more particularly, in the cooling and heating modes, focusing on cooling and heating by internal air circulation, and converting heat and moisture from the air discharged to the outside when switching to the ventilation mode. It is invented to reduce the installation space and to control the air conditioning in the house by realizing the heat exchanger to recover the energy efficiency to maximize the energy efficiency as well as implementing the heat pump air-conditioner and heat recovery type ventilation unit as an integrated device.

In general, a heat pump is a heating / cooling system that draws external heat to the room by using evaporative heat or condensation heat of the refrigerant, or discharges heat from the outside to the outside, and is classified into electric and engine types according to driving methods. This structure is a combination of cooling and heating.

Heat has the property of moving from a high place to a low place. A heat pump is named because it raises heat from a low temperature to a high temperature. In the beginning, a compressed refrigerant, such as a refrigerator, a freezer, and an air conditioner, is evaporated. It was developed to take heat away.

However, at present, a heating device that draws external heat into the room by using evaporative heat or condensation heat of the refrigerant, includes a cooling device that discharges heat from the outside, a heating device that transmits a high temperature heat source to a low temperature, and a combined heating and cooling device. It is used.

Such heat pumps are classified into electric, engine, and heat sources, waste heat sources, geothermal sources, etc., depending on the driving method, and hot air, cold and hot water, and cold water, depending on the heat supply method. It is divided into heating, cooling, dehumidification, and heating and cooling according to the use range of the pump.

The structure usually consists of a compressor, an evaporator, a condenser, an expansion valve, etc., and the principle of operation is to send high-temperature / high-pressure refrigerant from the compressor to an outdoor condenser for cooling, and to release high temperature heat to the outdoor condenser. The refrigerant, which has been condensed and cooled to low and low pressure due to pressure drop while passing through the expansion valve, is supplied to the evaporator in the room, absorbs heat, evaporates, and repeats the cycle of entering the compressor again. The evaporator is operated as a condenser so that the refrigerant compressed to high temperature and high pressure condenses as it emits heat in the room, and the low temperature and low pressure refrigerant evaporates while absorbing heat from the outside air as it passes through the expansion valve. The system is configured to warm the target point.
