Refrigeration control method of air cooling refrigerator

Abstract

The invention provides a refrigeration control method of an air cooling refrigerator. The method comprises the steps of: detecting the first temperature of the temperature-changing chamber of the air cooling refrigerator; comparing the detected first temperature with a first preset temperature of the temperature-changing chamber; detecting whether the compressor of the air cooling refrigerator is started or not if the first temperature is higher than or equal to the first preset temperature; refrigerating the temperature-changing chamber until the first temperature is lower than the second preset temperature if the compressor of the air cooling refrigerator is started; otherwise, comparing the first temperature with a third preset temperature; refrigerating the temperature-changing chamber until the first temperature is lower than the second preset temperature if the first temperature is higher than or equal to the third preset temperature, wherein the first preset temperature is lower than the third preset temperature but higher than the second preset temperature. According to the refrigeration control method provided by the invention, the frequent startup of the compressor can be reduced effectively, the service life of the compressor is prolonged and the energy efficiency of the refrigerator is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration control method for an air-cooled refrigerator. Background technique [0002] The variable room of the existing multi-temperature zone air-cooled refrigerator generally adopts an air duct to introduce cold air from the freezing room to achieve the purpose of cooling. At present, the control of this kind of variable greenhouse is to directly judge whether the measured temperature of the variable greenhouse has reached the start-up point temperature, and if it has reached, the variable greenhouse will start cooling. The specific process is as figure 1 shown. [0003] The disadvantage of the existing control method is that when the cooling room is required to be cooled, the damper is opened, and the freezing fan (F-FAN) is turned on, which will cause the temperature of the freezing room to rise rapidly. When the air door of the variable temperature ...
