What is the principle of the condenser？What are the effects？

How Condensers Work
The refrigerant is compressed by the compressor to the condenser, and there are capillary tubes at the end of the condenser. The capillary will produce resistance to liquefy the gaseous refrigerant compressed by the compressor to achieve the effect of heat release. The condenser is high pressure and will only be hot. The evaporator is cold, and the liquid refrigerant in the condenser passes through the capillary and reaches the evaporator, where it will quickly vaporize, evaporate and absorb heat, and achieve the cooling effect.

Type of condenser
According to the different types of cooling media, condensers can be classified into four categories.
Water-cooled type: In this type of condenser, the heat released by the refrigerant is taken away by the cooling water. Cooling water can be used once or recycled. Water-cooled condensers can be divided into vertical shell-and-tube type, horizontal shell-and-tube type and casing type according to their different structural types.
Air-cooled (also called air-cooled): In this type of condenser, the heat released by the refrigerant is carried away by the air. The air can be natural convection or forced flow by fan. This type of condenser is used in places where Freon refrigeration units are inconvenient or difficult to supply water.
Water-air cooling type: In this type of condenser, the refrigerant is cooled by water and air at the same time, but it mainly relies on the evaporation of cooling water on the surface of the heat transfer tube, and absorbs a large amount of heat from the side of the refrigerant as water. Latent heat of vaporization, the role of air is mainly to speed up the evaporation of water and take away water vapor. Therefore, the water consumption of this type of condenser is very small, and it is the preferred type of condenser for areas with dry air, low water quality, low water temperature and insufficient water volume. This type of condenser can be divided into two types according to its structure: evaporative type and leaching type.
Evaporation-condensation type: In this type of condenser, the cold effect produced by the evaporation of the refrigerant in another refrigeration system is used to cool the refrigerant vapor on the other side of the heat transfer partition wall, and promote the latter to condense and liquefy. Such as the evaporator-condenser in the cascade refrigerator.

The role of the condenser
The function of the condenser is to dissipate heat and cool down the high-temperature and high-pressure refrigerant vapor discharged from the compressor, making it condense into a liquid high-pressure refrigerant. It can cool and liquefy the high-pressure, high-temperature refrigerant (gas refrigerant) sent from the compressor.
