发电厂要用许多冷凝器使涡轮机排出的蒸气得到冷凝。在冷冻厂中用冷凝器来冷凝氨和氟利昂之类的制冷蒸气。石油化学工业中用冷凝器使烃类及其他化学蒸气冷凝。在蒸馏过程中，把蒸气转变成液态的装置也称为冷凝器。所有的冷凝器都是把气体或蒸气的热量带走而运转的。

Many condensing condensers are required to make the turbine exhaust power plant. Condensers are used in refrigeration plants to condense refrigeration vapor such as ammonia  Freon. In the petrochemical industry, condensers are used to condense hydrocarbons  other chemical vapors. In the distillation process, the steam into a liquid device is also known as the condenser. All condensers operate by taking away the heat of the gas  steam.
