Abstract

The invention discloses a flasher refrigeration system, a refrigerator with the refrigeration system and a control method thereof, wherein the flasher refrigeration system includes: a compressor, a condenser, a first throttling part, a flasher, a second section A closed loop connected in turn by flow components, evaporator, check valve and return air heat exchanger; refrigerant circulates in the closed loop for refrigeration; solenoid valve has two ports of inlet and outlet, and the inlet and flasher connection, the outlet is connected with the one-way valve and the return air heat exchanger; the control panel is connected with the solenoid valve, and is used to control the conduction and closing of the solenoid valve; in addition, a refrigerator with the refrigeration system and Its control method; the present invention controls the suction state of the gaseous refrigerant of the flasher to the suction port of the compressor through a solenoid valve, and adopts two times of throttling, which improves the gas-liquid separation effect of the flasher on the refrigerant, and not only realizes It not only improves the energy-saving operation of the refrigerator, but also helps to control the overall cost of the product.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a flasher 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 exchang...
