The condenser works by passing the gas through a long tube (usually coiled into a solenoid), allowing heat to escape into the surrounding air. Metals such as copper conduct heat well and are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks with excellent heat conduction performance are often added to the pipes to increase the heat dissipation area to accelerate heat dissipation, and the air convection is accelerated by the fan to 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 the throttle valve is throttled, it becomes low temperature and low pressure liquid. The low temperature and low pressure liquid working medium is sent to the evaporator, where the evaporator absorbs heat and evaporates into the low temperature and low pressure steam, which is transported to the compressor again, thus completing the refrigeration cycle. The single-stage steam compression refrigeration system is composed of four basic components: the refrigeration compressor, the condenser, the throttle valve and the evaporator. They are successively connected by pipes to form a closed system. The refrigerant constantly circulates in the system, changes its state and exchanges heat with the outside world
