Working principle of Hybrid Unit of Air Conditioner with Heat Exchanger

Refrigeration operation:


When the temperature in the cabinet reaches the refrigeration start-up temperature, the internal fan, external fan and compressor keep on successively (as shown in the figure below, the compressor is running).


heat exchanger

Heat exchange operation:


When the ambient temperature is low, the temperature inside the cabinet meets the start-up temperature of heat exchange, and the temperature difference inside and outside the cabinet meets the effective temperature difference of heat exchange, the internal fan and external fan remain open and the compressor remains closed (as shown in the figure below, no compressor is running).
