Heat exchange is an essential part of the cooling or heating system. Heat exchange is done with the help of a system named a heat exchanger. The system “heat exchanger” works by transferring heat from one medium to another, especially fluid and gas, or it can be a mixture of both.
Both condensation and evaporation are done by their respective systems named condenser and evaporator.
A condenser is known to work for heat exchange by transferring its heat into the surrounding. Whereas, an evaporator is known to work for heat exchange by absorbing the heat from the surrounding.
Both processes work by changing the state of their working substance. Some of the other relevant information is shared in the above text.
