Problems solved by technology

[0008] Firstly, when the refrigerant remaining in the evaporator is low enough to cool the inside of the refrigerator but the blower fan stops, available cool air is lost and energy is thus wasted
[0009] Secondly, when the inside of the refrigerator is in a high temperature state, the inside of the refrigerator cannot be further cooled due to the very high temperature of the refrigerant remaining in the evaporator but the blower fan continues to work, and the temperature of the refrigerator rises due to the heat generated by the blower fan.
At this point, obviously, the increased power consumption is due to the unnecessary work of the blower fan

Abstract

Provided are a device and a method for controlling the work of a blower fan. In the device and method, the temperature of the evaporator is measured, and the amount of refrigerant remaining in the evaporator is calculated from the measured temperature of the evaporator, so that the cold air of the evaporator can be fully used. According to the present invention, the efficiency of the refrigerator can be further improved.

Description

technical field [0001] The present invention relates to a method for controlling a refrigerator, and more particularly relates to a device and method for controlling the operation of a refrigerator blower fan, which can optimize the end time of the delayed operation of the blower fan so that it can be terminated when the compressor works Then use the cool air that remains in the evaporator. Background technique [0002] A cooling cycle device such as a refrigerator includes a compressor for compressing low-temperature / low-pressure refrigerant gas, a condenser for condensing the high-pressure refrigerant compressed by the compressor by dissipating heat from the high-pressure refrigerant, and a condenser for reducing condensation in the condenser. An expander in which the refrigerant expands adiabatically in the expander, and an evaporator in which the refrigerant deprives heat from the freezing and refrigerating chambers and evaporates. The evaporator includes a blower fan f...
