Problems solved by technology
Under different working conditions of the refrigerator (under different ambient temperatures), the refrigeration system cannot automatically adjust the flow of the coolant flowing from the capillary tube into the evaporator according to the change of the working condition, so the efficiency of the refrigerator cannot be maximized, and the energy consumption of the refrigerator is increased. And other issues

The invention discloses a refrigerator refrigeration system, a refrigerator and a control method for the refrigerator. The refrigerator refrigeration system includes: a compressor, a condenser, a dry filter, a capillary tube, a flow regulating valve, an evaporator, a return air heat exchanger, and a temperature sensor and control unit. The inlet of the condenser is connected with the outlet of the compressor, the inlet of the dry filter is connected with the outlet of the condenser, the inlet of the capillary is connected with the outlet of the dry filter, the evaporator is connected with the capillary, and the inlet of the flow regulating valve is connected with the outlet of the capillary , the outlet of the flow regulating valve is connected with the inlet of the evaporator to adjust the flow of refrigerant flowing from the capillary into the evaporator. The refrigeration system of the refrigerator of the present invention can precisely control the flow rate of the coolant flowing into the evaporator according to different ambient temperatures, thereby adjusting the power of the refrigerator refrigeration system to maximize it, and can effectively reduce the energy consumption of the refrigerator.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator refrigeration system, a refrigerator and a control method for the refrigerator. Background technique [0002] At present, the flow rate of the capillary tube in the existing refrigerator refrigeration system is fixed and unchangeable, so the flow rate of the coolant flowing from the capillary tube into the evaporator is also fixed. Under different working conditions of the refrigerator (under different ambient temperatures), the refrigeration system cannot automatically adjust the flow of the coolant flowing from the capillary tube into the evaporator according to the change of the working condition, so the efficiency of the refrigerator cannot be maximized, and the energy consumption of the refrigerator is increased. And other issues. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical probl...
