Control method for refrigerator

Abstract

The invention relates to the technical field of refrigerators, in particular to a control method for a refrigerator. The control method for the refrigerator comprises the steps that different control modes are operated according to different environment temperatures, refrigeration of a refrigerating chamber is conducted preferably when the environment temperature is smaller than a set environment temperature value as well as when the environment temperature is not smaller than the set environment temperature value and the temperature in a freezing chamber is smaller than a set freezing temperature value, and refrigeration of a temperature-variable chamber is conducted after refrigeration of the refrigerating chamber is completed; and whether refrigeration of the refrigerating chamber is needed or not is monitored while refrigeration of the temperature-variable chamber is conducted, and a throttling mechanism of the freezing chamber is controlled to be connected with a freezing refrigeration circuit when both refrigeration of the refrigerating chamber and refrigeration of the temperature-variable chamber are not needed, so that independent refrigeration of the freezing chamber is conducted. When the environment temperature is larger than the set environment temperature value and the temperature in the freezing chamber is not smaller than the set freezing temperature value, refrigeration of the refrigerating chamber is conducted after the refrigerator operates in the initial operating mode. According to the control method for the refrigerator, a compressor operates under a small load condition, so that damage caused by liquid impact is avoided, the refrigerating speeds of all the chambers are guaranteed, and the system stability is improved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a method for controlling a refrigerator. Background technique [0002] The control system of the existing three-chamber refrigerator is a parallel system, each chamber is controlled by a separate temperature sensor, and the on-off of the capillary leading to each chamber is controlled according to the temperature of the temperature sensor of each chamber. The set amount of refrigerant inhaled by the compressor should meet the maximum load when the freezing, refrigerating and variable temperature rooms all need cooling. The amount of refrigerant is small. At this time, the excess refrigerant in the refrigeration system is likely to cause liquid hammer damage to the compressor. Moreover, the inconsistent load in the refrigerator under high-temperature environment and low-temperature environment will also affect the amount of refrigerant charged in the compressor, resulting i...
