Working principle and classification of car condenser

Working principle of car condenser:

The refrigerant enters the evaporator, the pressure decreases, and it changes from high-pressure gas to low-pressure gas. This process needs to absorb heat, so the surface temperature of the evaporator is very low, and then the fan can blow out the cold air. The condenser is the The high-pressure and high-temperature refrigerant coming out of the compressor is cooled to high-pressure and low-temperature. Then it is vaporized through the capillary tube and evaporated in the evaporator.

car Condenser Classification

According to the different types of cooling media, condensers can be classified into four categories, and their functions are as follows:

(1) 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.

(2) Air-cooled type (also called air-cooled type): In this type of condenser, the heat released by the refrigerant is taken 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.

(3) 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.

(4) 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 to absorb a large amount of heat from the side of the refrigerant As the latent heat of vaporization of water, 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.That is all about car condenser.
