Abstract

PURPOSE: To eliminate inutile defrosting by selecting an input pulse number through the outside-air temperature or humidity in integrating the operation time of a compressor.
CONSTITUTION: A frequency divider 2, thermostat 3 for switching a contact piece 4 to high temperature contact H or a low temperature contact L according to the outside-air temperature, and a chattering preventing circuit 5 are connected between a counter 6 and a pulse source 1 which generated pulses, interlocked to the operation of a compressor. Accordingly, in high outside-air temperature, the output of the pulse source 1 is applied to the counter 6 as it is, according to the revolution in compression, and in low outside-air temperature, the output which was frequency- divided by a frequency demultiplier 2 is applied to the counter 6, and a defrosting signal 7 is transmitted, when a prescribed count completed. Thus, proper defrosting is carried out according to the outsideair temperature, and power consumption can be reduced. The thermostat 3 may be exchanged for humidity detector
