The condenser is one of the core components of the chiller system. It is a kind of heat exchanger. It can convert gas or vapor into liquid, and quickly transfer the heat in the tube to the air near the tube to achieve the purpose of heat exchange. The working process of the condenser is an exothermic process, so the condenser temperature is relatively high.

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

1.Water cooling type

In this type of condenser, the heat released by the refrigerant is taken away by the cooling water. The 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 sleeve type according to their different structural types.

2. Air-cooled 

In this type of condenser, the heat released by the refrigerant is taken away by the air. The air can be natural convection, or a fan can be used for the forced flow. This type of condenser is used in Freon refrigeration devices where water supply is inconvenient or difficult.

3. 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 refrigerant side as water The latent heat of vaporization, the role of air is mainly to accelerate 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: evaporative type and shower type according to its structure. 

4. Evaporation-condensation type

 In this type of condenser, the cooling 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 and promote the latter to condense and liquefy. Such as the evaporator-condenser in the cascade refrigerator.

Water-cooled condenser

This type of condenser uses water as a cooling medium to take away the heat released when the refrigerant is condensed. The cooling water can be used once or recycled. When using circulating water, it must be equipped with a cooling tower or cold pool to ensure that the water is continuously cooled. According to their different structures, there are mainly shell-and-tube type and sleeve-type heat exchangers, as well as the more commonly used plate heat exchangers.
