Problems solved by technology

This control method is simple and clear, but due to the different operating conditions of the refrigerator, such as different ambient temperatures, differences in the volume of each compartment, and differences in the amount of food in each compartment, it is likely that the cooling requirements of each compartment will not be synchronized. This leads to problems such as frequent start-up of the compressor and low cooling efficiency, which eventually leads to an increase in the energy consumption of the refrigerator

Embodiment 1

[0053] Such as figure 1 , in the present embodiment, air-cooled refrigerator comprises three compartments of refrigerating chamber, freezing chamber and temperature-changing chamber, and compressor, evaporator, fan motor and freezing chamber temperature sensor are installed in freezing chamber; Refrigerating chamber temperature sensor is installed in refrigerating chamber, The air duct between the refrigerating room and the freezing room is equipped with a refrigerating damper for controlling the temperature of the refrigerating room, a temperature sensor for the changing room is installed in the changing room, and a temperature changing damper for controlling the temperature of the changing room is installed in the air duct between the changing room and the freezing room , the freezing chamber temperature sensor, the refrigerating chamber temperature sensor and the refrigerating damper, the variable chamber temperature sensor and the variable temperature damper are all connec...

Embodiment 2

[0082] In this embodiment, the air-cooled refrigerator includes two compartments, a refrigerating compartment and a freezing compartment, and the control method is the same as above, except that the relevant control of the temperature-changing compartment is cancelled.

[0083] In summary, the difference between the present invention and the prior art is mainly reflected in two aspects, one: in the prior art, each compartment controls the start and stop of the compressor according to the temperature of each compartment, and there is no correlation between the compartments Judging, this may cause the refrigerator to not be refrigerated when the freezer needs to be refrigerated, and the refrigerated to be refrigerated when the freezer is not required to be refrigerated. As a result, the compressor only refrigerates one compartment when it is running, and the running time is prolonged. The control method of the present invention is to control the start-up of the compressor with th...

Abstract

The invention relates to a method for controlling an air-cooled refrigerator. The air-cooled refrigerator comprises a cold storage chamber and a freezing chamber; a compressor, an evaporator, a fan motor and a freezing chamber temperature sensor are arranged in the freezing chamber; a cold storage chamber temperature sensor is arranged in the cold storage chamber, and a cold storage air door for controlling the temperature of the cold storage chamber is arranged in an air duct between the cold storage chamber and the freezing chamber; and the freezing chamber temperature sensor, the cold storage chamber temperature sensor and the cold storage air door are connected with a controller of the air-cooled refrigerator. The method for controlling the air-cooled refrigerator comprises the following steps of: acquiring temperatures of the chambers through the freezing chamber temperature sensor and the cold storage chamber temperature sensor, and controlling the compressor, the fan motor and the cold storage air door through the controller to realize synchronization of refrigerating cycles of the chambers, wherein start of the compressor is only controlled by the temperature of the freezing chamber, and operation and stop of the compressor are controlled by the temperature of each chamber. By the controlling method, the start time of the compressor can be reduced, the refrigerating efficiency is improved, and an aim of reducing the operating energy consumption of the refrigerator is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a control method of an air-cooled refrigerator. Background technique [0002] Air-cooled refrigerators, also known as frost-free refrigerators, operate the compressor to make the evaporator absorb heat for cooling, and at the same time, the air circulation generated by the fan motor runs to flow the cold air on the evaporator to different compartments of the refrigerator and each box in the refrigerator. parts. [0003] After a period of cooling operation, the refrigerator will perform an automatic frosting process, turning the accumulated frost on the evaporator into water and discharging it out of the box, so as to realize the frost-free operation of the refrigerator. [0004] A refrigerator with multiple compartments is generally composed of a refrigerator compartment and a freezer compartment, and some models of refrigerators also have a variable temperatur...
