Condenser The components of the air conditioning system can transfer the heat from the pipe to the air near the pipe in a very fast manner. Most of the cars are placed in front of the tank. A device that turns a gas or vapor into a liquid. The power plant uses many condensers to condense the vapors discharged from the turbine; a condenser is used in the freezing plant to condense refrigerant vapors such as ammonia and Freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In distillation, the device that turns the vapor into a liquid is called a condenser. All condensers operate by taking away the heat of the gas or vapor.
