What is the working principle of the condenser?

The working principle of the condenser is that the gas passes through a long tube (usually coiled into a solenoid) to dissipate heat to the surrounding air. Metals such as copper have strong thermal conductivity 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 pipeline to increase the heat dissipation area to accelerate heat dissipation, and air convection is accelerated through the fan to take away heat.     
The refrigeration principle of general refrigeration machine is that compressor compresses working substance from low temperature and low pressure gas to high temperature and high pressure gas, then condenses into medium temperature and high pressure liquid through condenser. After throttling by throttle valve, it becomes low temperature and low pressure liquid. Low-temperature and low-pressure liquid working substance is fed into the evaporator, which absorbs heat and evaporates into low-temperature and low-pressure steam, which is fed into the compressor again, thus completing the refrigeration cycle.
The single-stage vapor compression refrigeration system is composed of four basic components: refrigeration compressor, condenser, throttle valve and evaporator. They are connected by pipes in turn to form a closed system. The refrigerant circulates continuously in the system, changes its state and exchanges heat with the outside world.
