refrigerator

Abstract

A refrigerator comprising: a first refrigeration cycle device including a first compressor, a first condenser, a first expansion mechanism, and a first evaporator through which a refrigerant flows; diverting the flow of cold air in a freezer compartment to the first evaporator and the first fan of the freezing chamber; the second refrigeration cycle device including the second compressor, the second condenser, the second expansion mechanism and the second evaporator through which the refrigerant circulates; a second fan of the second evaporator and the refrigerating chamber; a third fan blowing outside air to the first condenser and the second condenser; and a control module controlling the first and second compressors and the first to third fans, High-temperature initial simultaneous operation of driving the first and second compressors together is performed when the outside air temperature is a set temperature or higher, during which time the temperature of the freezing compartment exceeds the set temperature and the temperature of the refrigerating compartment is the set temperature or lower High-temperature initial alternate operation of driving the first to third fans and alternately driving the first and second compressors.

Description

technical field [0001] The present disclosure relates to refrigeration devices, and more particularly to refrigerators. Background technique [0002] A refrigerator is an apparatus for preventing spoilage or deterioration of food by cooling or storing products to be cooled (hereinafter referred to as "food") such as food, medicine, and cosmetics at a low temperature. [0003] A refrigerator includes a freezing chamber in which food is stored and a refrigeration cycle device for cooling the freezing chamber. [0004] A refrigeration cycle device may include a compressor through which a refrigerant circulates, a condenser, an expansion mechanism, and an evaporator. [0005] The refrigerator may include a freezer compartment maintained at a sub-zero temperature range and a refrigerated compartment maintained at an above-zero temperature range, and the freezer compartment and the refrigerated compartment may be cooled by at least one evaporator. [0006] The refrigerator can c...

AI Technical Summary

Problems solved by technology

[0009] A refrigerator with two independent refrigeration cycle devices can increase the current and power of the compressor to quickly reach the target temperature when the outside air temperature is high, and in this case, the control module for controlling the two refrigeration cycle devices Overheating in the event that the two refrigeration cycle units operate together for a long period of time, and when the control module overheats, the control module can be damaged or cause its abnormal operation
