Compressor, evaporator, outdoor air-cooled condenser and expansion valve concatenate to form a closed circulation by copper pipe,
The inside fills a certain amount of refrigerant.Under the pressure of compressor, coolant media evaporation endothermic in evaporator, gaseous coolant
Medium enters compressor, is entered by compressor high-pressure mouth and copper pipe in outdoor air-cooled condenser, is released with outdoor air heat exchange
Thermal discharge, coolant media becomes liquid from gaseous state condensation, and liquid refrigeration medium enters expansion valve by copper pipe, subsequently into room
Interior evaporator, enters back into compressor after being evaporated in evaporator, so moves in circles, and realizes indoor heat to outdoor transfer.
