In heating or cooling systems, the heat exchanger that functions as an evaporator is called an evaporator. Evaporation systems consist of four main components to complete the cooling cycle. These components are divided into four groups: compressor, condenser, expansion valve, and evaporator. The compressor performs the compression process, increasing the gas pressure and temperature, and sends it to the condenser. The hot and high-pressure gas sent to the condenser is condensed and its pressure reduced slightly before being sent to the expansion valve. The gas sent to the expansion valve passes through it, reducing both its pressure and temperature. The gas-liquid mixture that exits the expansion valve is sent to the evaporator, where the refrig ...
