Abstract

The invention discloses a refrigeration system, a refrigerator with the refrigeration system and a control method of the refrigerator. The refrigeration system comprises a compressor, a condenser, a throttling component, a flash generator, an evaporator, a one-way valve and an air return heat exchanger which are sequentially connected to form a closed loop; a refrigerating fluid is arranged and isused for circularly refrigerating in the closed loop; an electric flow regulating valve is arranged and is provided with an inlet and an outlet, the inlet is connected with the flash generator, and the outlet is connected with the one-way valve and the air return heat exchanger; and a control panel is arranged, is connected with the electric flow regulating valve and is used for controlling the opening degree of the electric flow regulating valve. In addition, the invention further provides the refrigerator with the refrigeration system and the control method of the refrigerator. According tothe refrigeration system, the refrigerator and the control method, the gas-liquid separation effect of a refrigerant through the flash evaporator is achieved, so that a refrigerant liquid is suppliedto the evaporator, refrigerant gas is guided to an air suction port of the compressor, and therefore high-efficiency operation of the refrigerating system is realized, and finally the requirement forthe energy-saving operation of the refrigerator is met.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration system, a refrigerator with the refrigeration system and a control method thereof. Background technique [0002] Refrigerator cooling requires energy. It is the relentless pursuit of refrigerator manufacturers to improve the power consumption of refrigerators by adopting various technical measures to make refrigerators more and more energy-efficient. [0003] Refrigeration System Reference for Conventional Refrigerators figure 1 As shown, it includes: a compressor 10 , a condenser 20 , a throttling component 30 , an evaporator 40 , and a return air heat exchanger 50 . When the refrigerator is refrigerated, the direction of the refrigerant in the refrigeration system is: compressor 10 → condenser 20 → return air heat exchanger 50 (first heat exchange tube) → throttling component 30 → evaporator 40 → return air heat exchanger 50 (second heat exchange tube)→...
