Refrigeration control method for refrigerator and refrigerator

Abstract

The invention provides a refrigeration control method for a refrigerator. The refrigerator includes a box body defining a refrigerated compartment and a refrigerated compartment, a door body for opening and closing the access openings of the refrigerated compartment and the refrigerated compartment, and a refrigeration system arranged in the box; the refrigerated system includes a compressor, a condensing The electromagnetic three-way valve used to switch the working state of the refrigeration system, the refrigerating evaporator and the freezing evaporator respectively used to provide cooling capacity for the refrigerating compartment and the freezing compartment, and defrosting for the refrigerating evaporator and the freezing evaporator respectively The refrigeration heating wire and the freezing heating wire; the refrigeration control method includes: the defrosting of the freezing evaporator is completed; the electromagnetic three-way valve is closed, and the refrigeration heating wire is working. The refrigeration control method for refrigerators of the present invention can increase the temperature and pressure of the refrigerant remaining at the bottom of the refrigeration evaporator after the defrosting of the refrigeration evaporator is completed, and move into the refrigeration evaporator through the evaporator connecting pipe, Reduced residual refrigerant in the refrigerated evaporator.

Description

technical field [0001] The invention relates to the field of freezing and refrigeration, in particular to a refrigeration control method for a refrigerator and the refrigerator. Background technique [0002] figure 1 It is a schematic diagram of the refrigerant cycle when the refrigerated compartment and the freezer compartment of the dual-system refrigerator are cooled at the same time. see figure 1 , in the prior art, the refrigeration system of a dual-system refrigerator generally includes a compressor 110, a condenser 120 communicating with the outlet of the compressor 110, an electromagnetic three-way valve 150 for switching the working state of the refrigeration system 100, a refrigeration capillary 131 and The refrigerating capillary 132, the refrigerating evaporator 141 and the refrigerating evaporator 142 that are respectively used to provide cooling for the freezing compartment and the refrigerating compartment, diffuse the cold generated by the refrigerating eva...

AI Technical Summary

Problems solved by technology

[0006] A further object of the first aspect of the present invention is to overcome the technical difficulties of insufficient refrigerant in the refrigerating passage and poor refrigeration on the basis of quickly starting to refrigerate the refrigerated compartment
