OPERATION CONTROL CIRCUIT OF REFRIGERATOR HAVING HIGH EFFICIENCY MULTI-EVAPORATOR CYCLE(H.M.CYCLE) AND OPERATION CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To enable a freezing chamber and a refrigerator chamber to be controlled independently for their temperatures by a method, wherein a first fan arranged in the freezing chamber and a second fan mounted in the refrigerator chamber are operated at the same time. SOLUTION: At a microcomputer 50, the temperature of a freezing chamber detected by a freezing chamber temperature sensor 24 and a freezing chamber setting temperature set by a freezing chamber temperature adjusting machine 23 are compared to each other, At this time, when the temperature of the freezing chamber is higher than the set temperature of the freezing chamber, a relay 51 is operated to keep a switch SW in the on state. With such an arrangement, a compressor 41, a first fan 22 an a second fan 32 become operating simultaneously. Then, these operations are continued and when a temperature of the freezing chamber 20 is lower than a set temperature of the freezing chamber, the operation of the relay 51 is stopped and the switch SW is turned off. As a result, all the operations of the compressor 41, the first fan 22 and the second fan 32 are stopped.
