Abstract

PURPOSE: This is the improved defrosting control system, under which defrosting can be initiated by the correlative values of the difference of temperature between the refrigerant of an out-of-door heat exchanger, and that of the air from the proposed heat exchange r. At the same time, the defrosting operation can also be terminated by the difference of temperatures, between that of the connecting pip leading to the four sides valve, and the room heat exchanger, and the refrigerant of this heat exchanger.
