The working principle and application of the condenser

Working principle
The gas passes through a long tube (usually coiled into a solenoid), allowing heat to be lost to the surrounding air. Metals such as copper, which conduct heat, are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks with excellent heat conduction performance are often attached to the pipes to increase the heat dissipation area to accelerate heat dissipation, and the air convection is accelerated through the fan to take away the heat.

The refrigeration principle of the general refrigerator is that the compressor compresses the working medium from low temperature and low pressure gas into high temperature and high pressure gas, and then condensates into medium temperature and high pressure liquid through the condenser, and becomes a low temperature and low pressure liquid after the throttle valve is throttled. The low-temperature and low-pressure liquid working medium is sent into the evaporator, which absorbs heat and evaporates into low-temperature and low-pressure steam, which is transported into the compressor again to complete the refrigeration cycle.

Single-stage steam compression refrigeration system is composed of four basic components of refrigeration compressor, condenser, throttle valve and evaporator, which are successively connected by pipes to form a closed system, and the refrigerant constantly circulates in the system, changes state, and exchanges heat with the outside world.

Application
Condensers are widely used in power plants, refrigerating plants and petrochemical industries. Among them, in the power plant, the condenser is used to condense the steam discharged by the turbine; Condensers are used in refrigeration plants to condense refrigerating vapors such as ammonia and freon. Condensers are used in the petrochemical industry to condense hydrocarbons and other chemical vapors.
