Problems solved by technology
The biggest defect of this kind of solenoid valve is that it has a large action noise, and it cannot realize the "pressure relief" function itself. It is required to design a special "pressure relief capillary" with condensation function or add a "two-position two-way" pressure relief solenoid valve. The resulting problems are "slow response" of the pressure relief circuit, poor closing performance of the one-way valve, many parts, and unstable energy-saving effect of the refrigerator

Description
technical field [0001] The invention relates to a three-cycle refrigeration system provided with electric valves. Background technique [0002] Ordinary household refrigerators mostly belong to the vapor compression refrigeration system, which controls the temperature inside the refrigerator by controlling the start and stop of the compressor. However, when the compressor stops working, the pressures of the condenser and the evaporator tend to be balanced, and during the balancing process, the hot refrigerant flows into the evaporator through the capillary tube, causing unnecessary energy loss to the refrigerator. When the compressor starts, the condenser and evaporator also lose some energy during the process of re-establishing the pressure difference. The more frequently the refrigerator is turned on and off, the more energy is lost. This part is due to the energy loss caused by the start and stop of the compressor, which will increase the power consumption of the refrige...
