A Freezer Condenser is a part of the refrigeration system, which is a kind of heat exchanger, which can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube a very fast manner.

Power plants use many condensers to condense the steam discharged from the turbine. Condensers are used in refrigeration plants to condense refrigerant vapors such as ammonia and freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In the distillation process, the device that converts vapor to liquid is also called a condenser. All condensers operate by taking away the heat of gas or steam.

The evaporator is a medium that absorbs heat and vaporizes and absorbs external heat, that is, the refrigerant changes from gas to a liquid, which is a condensation and heat release process, and its internal pressure is generally very high; while the refrigerant of the evaporator changes from liquid to liquid. The gaseous state is an evaporative endothermic process, and its internal pressure is generally low.
