Problems solved by technology

This control method can also achieve energy-saving effects. The speed of the frequency conversion fan is changed in the same way. Even when multiple frequency conversion fans are running at the same time, each fan can only run in the same way when using this control method. This has an energy-saving effect on the refrigeration system of the refrigerator. not optimal

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0019] Such as figure 1 As shown, a control method of an air-cooled refrigerator, the refrigeration system of this air-cooled refrigerator includes a compressor 1, a condenser 2, a refrigeration evaporator 3, a refrigeration evaporator 4, a condensation fan 5, a refrigeration fan 6, a refrigeration fan 7, Controller, refrigerating temperature sensor, freezing temperature sensor and ambient temperature sensor.

[0020] Compressor 1 discharges high-temperature and high-pressure refrigerant into condenser 2, and exchanges heat with air in condenser 2. At the same time, condensing fan 5 is turned on, and the condensed refrigerant enters dew removal pipe 8 and then enters filter 9 and solenoid valve. 10. Divided into two paths by the solenoid valve 10, one of which is connected to the inlet of the refrigeration evaporator 4 through the refrigeration...

Abstract

The invention relates to an air-cooling refrigerator control method. A refrigeration system of an air-cooling refrigerator comprises a compressor, a condenser, a freezing evaporator, a cold storage evaporator, a condensate fan, a freezing fan, a cold storage fan, a cold storage temperature sensor, a freezing temperature sensor, an environment temperature sensor and a controller, wherein the controller of the refrigerator controls the rotating speeds of the compressor, the condensate fan, the freezing fan and the cold storage fan according to the temperature of a cold storage chamber, the temperature of a freezing chamber and the temperature of the external environment detected by the cold storage temperature sensor, the freezing temperature sensor and the environment temperature sensor respectively. Due to the arrangement of the environment temperature sensor for measuring the temperature of the external environment on the refrigerator, the rotating speeds of the compressor, the condensate fan, the freezing fan and the cold storage fan can be adjusted simultaneously according to the temperature of the external environment and the temperature of each internal chamber, the refrigeration system is optimized, the temperature in the refrigerator can be controlled more accurately and quickly, and energy consumption and noise are reduced to the lowest level.

Description

technical field [0001] The invention relates to a control method of an air-cooled refrigerator, in particular to a control method of an air-cooled refrigerator capable of adjusting its own cooling capacity output according to the temperature of the external environment of the refrigerator, and belongs to the technical field of refrigerator control. Background technique [0002] Generally, the fans in the refrigerator are fixed-speed fans. In order to achieve the cooling capacity required by the refrigerator when the external ambient temperature is high, the fan speed is set relatively high. Under various ambient temperatures, the fan speed cannot be changed, resulting in Solved the problems of high operating noise of the refrigerator, high energy consumption and low efficiency of the refrigeration system. [0003] At present, some refrigerators can adjust the speed of the fan according to the external ambient temperature of the refrigerator, and divide the external ambient t...
