The temperature of the water-cooled condenser is abnormally high What caused it!

What is mentioned here is a water-cooled condenser, which is mainly used in water-cooled chillers. Its function is to convert the high-temperature refrigerant vapor discharged from the compressor into a liquid refrigerant, which is important for the refrigeration system to radiate heat to the surrounding environment. Equipment is one of the four major components of the chiller, and its quality directly affects the cooling capacity and efficiency.

　　 In the working process of the water-cooled chiller refrigeration system, the temperature of the outer surface of the condenser is generally close to normal temperature, and it does not feel hot when it is touched by hand. Once the surface temperature is found to be too high, you should immediately find out the cause and take measures to eliminate this phenomenon.

　　 Under normal circumstances, the main cause of the increase in the temperature of the condenser is the problem of the cooling water, usually in the following four situations:

　　 1. The position of the cooling water inlet pipe and outlet pipe are installed incorrectly

The normal installation position is generally low inlet pipe, high outlet pipe, and "low inlet and high outlet". If the inlet pipe is located high, the cooling water cannot be fully filled in the condenser, and the heat transfer area will become smaller. The solvent vapor cannot be effectively condensed, causing the surface temperature of the condenser to rise.



　　2, the quality of the cooling water is too poor

　　 causes scaling on the inner wall of the cooling water pipe in the condenser and increases the thermal resistance, which affects the heat exchange between the refrigerant and the cooling water, and reduces the heat transfer effect. Such failures often occur in chillers that have been used for a long time and are not cleaned regularly. The solution is to remove the scale.

　　 3. The amount of cooling water is insufficient and the water pressure is insufficient.

The water-cooled condenser relies on the cooling water to take away the latent heat released by the refrigerant vapor condenser, so the cooling water pressure is not enough, the flow rate does not meet the rated requirements, the heat dissipation capacity will be limited, and finally the outer surface temperature of the condenser will rise .

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

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