Operating controlling method of refrigerator

Abstract

The present invention relates to an operation control method of refrigerator. For the directly-cooled refrigerator with refrigerator compartment and special region it can repeatedly make the following steps: step 1, detecting the temperature of refrigerator compartment, when its detected temperature is greater than first reference temperature, driving compressor, closing special region valve and opening refrigerator compartment valve so as to supply cold air; step 2, detecting temperature of refrigerator compartment, when its detected temperature is less than first reference temperature, closing refrigerator compartment valve and opening special region valve; step 3, detecting temperature of special region, comparing the detected temperature with second reference temperature; and step 4, according to the compared result, when the temperature of special region is less than second reference temperature, stopping compressor, when the temperature of special region is greater than second reference temperature, continuously driving compressor.

Description

technical field [0001] The invention relates to an operation control method of a refrigerator. Background technique [0002] Such as figure 1 As shown, the high-temperature and high-pressure refrigerant discharged from the compressor (1) releases heat when passing through the compressor (2), and is decompressed in the capillary tube (3) to become a low-temperature and low-pressure refrigerant. [0003] The above-mentioned low-temperature and low-pressure refrigerant first absorbs heat through the evaporator (6) of the freezer compartment (4), then absorbs heat through the evaporator (7) of the refrigerator compartment (5), and is finally sucked into the compressor (1). [0004] The freezing evaporator (6) installed in the freezing compartment and the refrigerating evaporator (7) installed in the refrigerating compartment are direct cold plate-shaped evaporators. The freezing evaporator (6) of the freezer is made of an area that can cover the other surfaces (upper, bottom, ...

Problems solved by technology

[0009] However, as mentioned above, when the valves of the refrigerating room and the special area are independently controlled, since the space of the special area is small, the on / off driving cycle of the compressor supplying the above-mentioned special area with cold air is too short, resulting in Unnecessary energy loss, while the compressor is vulnerable to damage due to its frequent on / off operations
