Among all the machines in our life, condenser is one of the commonly used types, which varies according to the requirements of different places. The type of condenser is different from the function of the product. What are the functions of the four condensers in our life?
As an important part of refrigeration system, condenser is a kind of heat exchanger. It can also change gases or vapors into liquids. The heat in the tube is quickly transferred to the air near the tube through the quenched and tempered round steel. Because the working process of condenser is exothermic, the temperature of condenser is very high.
Many condensers are used in power plants to condense the steam from the turbine. In refrigeration equipment, condenser is used to condense refrigeration steam, such as ammonia and Freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In distillation, the device that converts steam into liquid is also called condenser.
Different types of condensers and their functions
All of the above condensers used in different industries operate by removing heat from the gas or steam, but they can be divided into different types. One is a water-cooled condenser in which the heat released by the refrigerant is taken away by the cooling water. Cooling water can be used once or recycled. According to the different structure, it can be divided into vertical shell and tube type, horizontal shell and tube type, etc.
The other is an air-cooled condenser in which the heat released by the refrigerant is carried away by the air. Air can be either natural convection or forced flow by fans. It is mainly used in freon refrigeration equipment with inconvenient or difficult water supply.
There is also a water air cooling condenser, whose refrigerant is cooled by water and air at the same time, but it mainly depends on the evaporation of cooling water on the surface of heat transfer tube, and absorbs a lot of heat from the refrigerant, and the latent heat of water vaporization is on the side; the role of air is to accelerate the evaporation of water and carry away water vapor.
Therefore, the water consumption of this kind of condenser is very small, and it is the first choice for the areas with dry air, low water quality, low water temperature and insufficient water quantity. This kind of condenser can be divided into evaporation type and drenching type according to its different structure.
In addition, evaporative condensing condenser is one of the most commonly used models. It will rely on the cooling effect produced by the evaporation of refrigerant in another refrigeration system to cool the refrigerant vapor on the other side of the heat transfer wall, thus condensing and liquefying the latter. Evaporation in a cascade refrigerator is the type of condenser used.
