The water cooled condenser referred to here is mainly used in dry water cooled chillers. Its function is to convert the high-temperature refrigerant vapor discharged by the compressor into liquid refrigerant, which is the cooling system directed towards the surrounding environment

The important equipment for centralized heat release in the environment is one of the four major components of a chiller, and its quality directly affects the refrigeration capacity and efficiency.

During the operation of a water-cooled chiller refrigeration system, the outer surface temperature of the condenser is generally close to room temperature, and it cannot be felt hot when touched by hand. Once the surface temperature is found to be too high, the cause should be immediately identified and measures taken to eliminate this phenomenon.

In general, the main cause of the temperature increase in the condenser is the problem of cooling water, and there are usually four situations:

1. Incorrect installation of cooling water inlet and outlet pipes

The normal installation position is generally low in the inlet pipe, high in the outlet pipe, and "low in high out". If the inlet pipe is high, it is impossible for the cooling water to fully swirl inside the condenser, resulting in a smaller heat transfer area and ineffective condensation of refrigerant vapor, resulting in an increase in the surface temperature of the condenser.

2. The quality of cooling water is too poor

Causing scaling on the inner wall of the cooling water pipe in the condenser, increasing thermal resistance, affecting the heat exchange between the refrigerant and cooling water, and reducing heat transfer efficiency. This type of malfunction occurs in cold water that has been in use for a long time and has not been regularly cleaned

It often occurs in the unit. The solution is to remove scale.

3. Insufficient cooling water volume and water pressure

A water-cooled condenser relies on cooling water to remove the latent heat released by the refrigerant vapor condenser. Therefore, if the cooling water pressure is insufficient and the flow rate does not meet the rated requirements, the heat dissipation capacity will be limited, ultimately causing an increase in the outer surface temperature of the condenser.

4. The cooling water temperature is too high, higher than the rated working temperature.

The higher the temperature of the cooling water, the smaller the cooling temperature difference and heat transfer of the refrigerant. The refrigerant cannot be effectively cooled, and the surface temperature of the condenser will increase.
