KR960044034A - A refrigerator having a high efficiency multi-evaporator cycle (H. M. CYCLE) and a control method thereof - Google Patents

Abstract

An object of the present invention is to independently control the refrigerating chamber and the freezing chamber, and simultaneously control the refrigerating chamber and the freezing chamber to the set temperature band.

The present invention provides a control method of a refrigerator having a compressor, a freezer compartment and a refrigerated compartment which are separated from each other, wherein a first cooler and a cold room fan are installed in the refrigerating compartment and a second cooler and a freezing compartment fan are installed in the freezing compartment, (Step 211). If the temperature of the freezing compartment is higher than the freezing compartment set temperature, the temperature of the freezing compartment is adjusted to a suitable temperature for refrigerating the foodstuff (Step 212), and if the temperature of the refrigerating compartment is higher than the set temperature of the refrigerating compartment, the compressor and the freezing compartment fan and the refrigerating compartment fan are both operated (step 213).
