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] The control method of the air-cooled refrigerator is:

[0054]The freezer temperature sensor, refrigerated temperature sensor and variable room temperature sensor respectively collect the temperature of the compartment, and control the compressor, fan motor and refrigeration damper through the controller to realize the synchronization of the refrigeration cycle of each compartment. The temperature of the freezer is controlled, and the operation and stop are controlled by the temperature of each compartment. The control of the fan motor is not only related to the status of the compressor, but also related to the status of the refrigerating room and the changing room. The opening and closing of the refrigerating damper is controlled by the temperature of the refrigerating room, but when the compressor is running or stopped, its control parameters are also changed accordingly. The switch of the variable temperature air door is controlled by the temperature of the variable...

Embodiment 2

[0082] 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 the freezer as the main control. During the operation of the compressor, the refrigeration of the freezer is controlled through the refrigeration damper according to the temperature change of the freezer, so that the cooling of the freezer has a certain amount of advance. In...

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...
