Abstract

PURPOSE: To scheme to reduce operation power consumption by providing a frosting detecting device and a timer which generates defrosting instruction and combining timer system and demand system.
CONSTITUTION: The apparatus consists of the following: a thermostat 2 which operates and stops a compressor 3 through detecting the temperature of refrigerating chamber, defrosting switching relay 5, defrosting thermostat 7, pulse generator 9 which contacts the compressor 3 side of the thermostat 2 which generates the input signal for a power counter 10, RSS type flip-flops 11 and 12 which generate output signals continually until the reset signal arrives, when counter output pulses P' and P arrive, frosting detecting device 13 for demand defrosting which detects frosting and generates defrosting signal, defrosting instruction device 16 which operates a defrosting switching relay 4 to defrosting side, reset device 17 which generates defrosting end signals, AND circuit 14, and an OR circuit 15 etc., and thus, the operation power consumption is reduced.
