Condenser is a kind of refrigeration system. It is a kind of heat exchanger. It can convert gas or vapor into liquid, and transfer the heat in the pipe to the air near the pipe in a fast way. The working process of the condenser is an exothermic process, so the condenser temperature is high.The power plant uses a number of condensers to condense the vapors from the turbine. A condenser is used in a freezer to condense refrigeration vapors such as ammonia and Freon. Condensers in the petrochemical industry condense hydrocarbons and other chemical vapors. In the distillation process, the means for converting the vapor into a liquid is also referred to as a condenser. All condensers operate by taking away the heat of the gas or vapor.
A heat exchanger is a device that transfers some heat of a warm fluid to a cold fluid. Heat exchangers are common equipment in the chemical, petroleum, power, food and many other industrial sectors and occupy an important position in production. In chemical production, heat exchangers can be used as heaters, coolers, tube condensers, evaporators and reboilers. There are many varieties of heat exchangers, but the principles and methods of heat exchange between cold and warm fluids can be basically divided into three categories: partition wall, hybrid and regenerative. Among the three types of heat exchangers, the partition wall heat exchanger is the most used.
