KR960044035A - 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 refrigerator compartment and the freezer compartment to simultaneously cool the both compartments, and to increase the energy efficiency by delaying the cooling of the freezer compartment, if necessary.

A method for controlling a refrigerator having a compressor, a freezer compartment and a refrigerating compartment partitioned into a refrigerating compartment, a first refrigerator and a refrigerating compartment fan installed in the refrigerating compartment, and a second refrigerator and a freezing compartment fan installed in the freezing compartment, (Step 231). If the freezer compartment temperature is higher than the freezer compartment set temperature, the predetermined compartment compartment temperature is compared with the temperature of the refrigerating compartment and the appropriate temperature for refrigeration of the food, (Step 232). If the temperature of the freezing compartment is higher than the freezing compartment temperature, the freezing compartment temperature is compared with the second freezing compartment temperature (step 233). If the freezing compartment temperature is lower than the second freezing compartment temperature, (Step 235). If the freezer compartment temperature is higher than the surface temperature of the second refrigerator, the compressor, freezer It includes turning on the fan and the refrigerator compartment fan (step 234) step.
