Abstract

The invention discloses a refrigerating system, a refrigerator with the refrigerating system and a control method thereof, wherein the refrigerating system includes: a compressor, a condenser, a throttling component, a flasher, an evaporator, a one-way valve and a return air exchanger Heaters are sequentially connected into a closed circuit; refrigerant circulates in the closed circuit for refrigeration; electric flow regulating valve has two ports of inlet and outlet, the inlet is connected with the flasher, the outlet is connected with the one-way valve and the return air exchange connected to the heater; the control board is connected with the electric flow regulating valve, and is used to control the opening of the electric flow regulating valve; in addition, a refrigerator with the refrigeration system and its control method are also provided; The gas-liquid separation effect of the evaporator on the refrigerant, the refrigerant liquid is supplied to the evaporator, and the refrigerant gas is directed to the suction port of the compressor, thereby realizing the high-efficiency operation of the refrigeration system and finally meeting the requirements of energy-saving operation of the refrigerator.

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)→...
