Condenser vs. Heat Exchanger: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 4, 2024
A condenser cools gases into liquids, while a heat exchanger transfers heat between fluids without mixing them.
Key Differences
A condenser is specifically designed to cool gases and convert them into liquids by removing heat. It's a critical component in systems like air conditioners and refrigerators. In contrast, a heat exchanger is a device that allows heat transfer from one fluid to another without mixing them, used in various applications, including heating, cooling, and power generation.
The primary function of a condenser is the phase change of a substance from its gaseous to liquid state. This is achieved by lowering the temperature of the gas until it reaches its condensation point. On the other hand, a heat exchanger typically involves no phase change; it's designed to transfer heat between two or more fluids at different temperatures.
In terms of construction, a condenser often has coils or tubes through which the gaseous substance flows. As the gas cools and condenses, it releases heat which is removed by a coolant or the surrounding environment. A heat exchanger can be designed in various forms, such as shell and tube, plate, or finned, depending on the application, allowing efficient heat transfer between fluids.
Condensers are essential in systems where condensation is a part of the cycle, such as in refrigeration cycles, steam power plants, or distillation processes. Conversely, heat exchangers are used in a wider range of applications, from domestic heating systems to large industrial processes, where heat recovery or dissipation is needed.
Examples of condensers include the outdoor unit of an air conditioner or the condenser in a steam turbine. Examples of heat exchangers include radiators in cars, boilers in heating systems, and evaporators in refrigeration systems.
