The condenser of the air conditioning system can transfer the heat in the pipe to the air near the pipe in a very quick way. Most of the condensers on cars are installed in front of the water tank. A device that converts gas or steam into a liquid. A power plant uses many condensers to condense steam from its turbines; Condensers are used in refrigeration plants to condense refrigerating vapors such as ammonia and freon. Condensers in the petrochemical industry condense hydrocarbons and other chemical vapors. In the distillation process, the device that changes the vapor into a liquid state is called the condenser. All condensers operate by taking away the heat from gases or vapors.
