Work principle of air cooled condenser:
The pressure will decrease when refrigerant into the evaporator,change from high-pressure gas into low-pressure gas, this process will absorb heat, so the evaporator surface temperature is very low, and then through the fan,
it forms cold wind. The high-pressure, high temperature refrigerant from the compressor will become to high pressure, low temperature by the air cooled condenser. Then goes through the capillary gasification and evaporation in the
Air cooled Condenser can be grouped into four categories, its role is as follows:
1.Water to air type: In this type of condenser, the refrigeration equipment and the refrigerant are cooled by both water and air at the same time, but mainly rely on the amount of heat absorbed from the refrigerant side by the evaporation of the cooling water on the surface of the heat transfer pipe as the latent heat of vaporization of air, The main role of air is to speed up the evaporation of water and take away the water vapor.
2.Air cooled type : In this type of condenser, the heat released by the refrigerant is taken away by the air. The air can be either natural convection or fan-forced flow. Such condensers are used in Freon refrigerators for inconvenient
or difficult water supply, so this Condenser water consumption is very small. For air drying, water quality, low water temperature and insufficient water area is the preferred type of condenser, this type of condenser according to their different structure can be divided into two types of evaporation and pouring.
3.Water cooled type: In this type of condenser, the heat released by the refrigerant is taken away by the cooling water, the cooling water for the freezer can be used once or for recycling, and according to different structural forms, the water-cooled condenser can be divided into vertical shells,Tubular, horizontal shell tube and casing and other kinds.
4.Evaporative condenser:In this type of condenser system, the cooling effect by the evaporation of the refrigerant in the other refrigeration system is taken to cool the refrigerant on the other side of the heat transfer wall, which causes the latter to condense and liquefy
