The gas passes through a long tube (usually coiled as a solenoid) to allow heat to be lost to the surrounding air, and metals such as copper are good conductors of heat and are often used to transport steam. In order to improve the efficiency of the condenser, heat sink with excellent heat conduction performance is often added to the pipe, so as to increase the heat dissipation area, accelerate heat dissipation, accelerate air convection through the fan, and take the heat away.
The refrigeration principle of the general refrigerator is that the compressor compresses the working medium from low temperature and low pressure gas into high temperature and high pressure gas, and then condenses into medium temperature and high pressure liquid through the condenser. After being throttled by the throttle valve, it becomes low temperature and low pressure liquid. The liquid working medium of low temperature and low pressure is sent into the evaporator, which becomes the steam of low temperature and low pressure through heat absorption and evaporation in the evaporator, and then transported into the compressor again, so as to complete the refrigeration cycle.
Single-stage steam compression refrigeration system, is composed of refrigeration compressor, condenser, throttle valve and evaporator four basic components, they are connected by pipes in turn, forming a closed system, refrigerant in the system constantly circulating flow, state changes, heat exchange with the outside world.
