What are the roles of condenser and evaporation in split air conditioning

The condenser is an accessory of the refrigeration system, which belongs to a heat exchanger, which can convert the gas into a liquid, and transfer the heat in the tube to the air near the tube in a very fast way.

Evaporator is a heat exchanger, the high pressure liquid refrigerant enters the evaporator through the expansion valve, due to the atomization of the expansion valve, the liquid refrigerant becomes a mist, and the mist refrigerant transforms into a gaseous state under low pressure conditions. In the process of transformation, heat will be absorbed, so at this time the evaporator is cool, and after the wind passes, it becomes a cool wind to achieve the purpose of refrigeration.

The gas passes through a long tube (usually coiled into a solenoid), allowing heat to be lost to the surrounding air. Metals such as copper, which conduct heat, are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks with excellent heat conduction performance are often attached to the pipes to increase the heat dissipation area to accelerate heat dissipation, and the air convection is accelerated through the fan to take away the heat.

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 condensates into medium temperature and high pressure liquid through the condenser, and becomes a low temperature and low pressure liquid after the throttle valve is throttled. The low-temperature and low-pressure liquid working medium is sent into the evaporator, which absorbs heat and evaporates into low-temperature and low-pressure steam, which is transported into the compressor again to complete the refrigeration cycle.
