Refrigeration control method of refrigerator

Abstract

The invention provides a refrigeration control method of a refrigerator. The refrigeration control method comprises the following steps of: detecting whether a freezing chamber of the refrigerator meets a refrigeration condition, if so, starting a compressor for refrigerating in the freezing chamber, detecting whether at least one of a refrigerating chamber and a temperature varying chamber requests refrigeration in the current running process of the compressor; if at least one chamber requests refrigeration, judging whether at least one chamber requests refrigeration for the first time in the current running process of the compressor, if so, simultaneously refrigerating at least one chamber, and judging whether the freezing chamber meets a refrigeration stop condition after finishing of refrigerating for the at least one chamber; and if so, controlling the compressor to shut down so as to finish the current running process of the compressor, if not, unceasingly refrigerating the freezing chamber until that the freezing chamber meets the refrigeration stop condition, and controlling the compressor to shut down. The method provided by the embodiment of the invention can meet the refrigerator refrigeration requirement, meanwhile, the home using ratio of the compressor is reduced, and the method provided by the invention has the advantages that the energy consumption is low and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration control method for a refrigerator. Background technique [0002] At present, most of the three-door refrigerators use the direct cooling three-system control principle. Since each storage room is controlled by a separate system, this method can realize the automatic cooling control of the refrigerator room, variable temperature room, and freezer room, and intelligently judge the temperature of each storage room inside the refrigerator. Is it cooling. figure 1 It is a schematic diagram of an existing refrigerator refrigeration system. figure 1 The control principle of the solenoid valve is shown in Table 1: [0003] [0004] Table 1 [0005] According to the control mode of the existing computer temperature-controlled refrigerator, each chamber has the possibility of turning on the compressor. For example: [0006] Cold room request conditio...

Problems solved by technology

[0009] like figure 2 As shown, curve 1 is the running curve of the compressor on and off. The start and stop of the compressor is very irregular. The disadvantage of the existing scheme is that the compressors can be turned on at any time in each control room of the refrigerator, resu
