ABSTRACT:
The present invention provides an air-condition heat pump capable of defrosting and air-conditioning at same time. The present invention utilizes at least two evaporators, which harvest the energy from one working evaporator to provide energy for defrost operation of another evaporator, thus the air-condition heat pump can defrost without additional energy. Under low temperature working condition, the present invention utilizes a suction pressure boost to increase efficiency.
