Working principle of condenser

The auto ac condenser is designed to transfer heat from the working fluid (for example, water in a steam power plant) to the auxiliary fluid or the surrounding air. The condenser relies on the effective heat transfer that occurs during the phase change, in this case, it condenses the vapor into a liquid. The vapor usually enters the condenser at a temperature higher than the temperature of the secondary fluid. As the steam cools, it reaches its saturation temperature, condenses into a liquid and releases a lot of latent heat. When this process occurs together with the condenser, the amount of vapor decreases and the amount of liquid increases; at the outlet of the condenser, only liquid remains. Some condenser designs include extra length to subcool the condensed liquid to below the saturation temperature.

There are countless changes in car condenser design, and its design variables include working fluid, auxiliary fluid, geometry and material. Common secondary fluids include water, air, refrigerants or phase change materials.

Compared with other cooling technologies, the condenser has two important design advantages:

Latent heat transfer is more effective than only sensible heat transfer

During condensation, the temperature of the working fluid remains relatively constant, which maximizes the temperature difference between the working fluid and the auxiliary fluid.
