Abstract

PURPOSE: To decrease power consumption by providing a defrosting stop circuit operating for a defrosting circuit when defrostation comes to completion before a time set therefor.
CONSTITUTION: When a time t1 passes after an automatic defrosting device is conducting, an output signal is issued from a timing circuit 8 and an open air temperature x and an outdoor side heat exchanger temperature y stand in a domain coming under a straight line i (y≤ax-b), a power is put out of a frost detection circuit 9. Then, a defrosting circuit 10 is actuated by way of an AND circuit 12, and a defrosting operation is commenced. Next, when the outdoor side heat exchanger temperature comes at y≥c, or in a domain coming over a straight line ii, an output signal is issued from a deforsting stop circuit 11 to OR circuits 13, 14, an output signal is then issued from the OR circuit 13, 14 to the timing circuit 8 and the defrosting circuit 10, and thus the defrosting operation is stopped even before a time set therefor.
