What factors will cause the cooling performance of water-cooled chillers to decline

Water-cooled chillers are especially suitable for places with abundant water resources. The operation is more stable. It has the characteristics of large single-unit cooling capacity and high cooling efficiency. Therefore, it is often used in chemical plants, pharmaceutical plants, electroplating plants, etc. that require large cooling capacity industry.

When water-cooled chillers are in use, they need supporting cooling towers and water pumps for heat dissipation to provide circulating cooling water. The installation is a bit more complicated than air-cooled chillers. The next thing I want to introduce to you is the factors that cause the cooling performance of the water-cooled chiller to decline, let's take a look.

　　 1. Part of the factor is that the water source used by the water-cooled chiller has impurities. After a long period of time, it has accumulated and adhered to the pipes between various equipment, resulting in a small water flow. Therefore, it is necessary to clean the pipes between the equipment;

　　2. As far as the chiller factory is concerned, all chillers will undergo performance testing before leaving the factory to ensure the normal operation of the unit. If the indoor temperature cannot be lowered during the first use, it is possible that the water-cooled chiller is not equipped correctly;

　　3. The temperature of the cold-water chiller cannot be lowered when it is used for the first time. Another reason is that there is a small problem in the installation between the water-cooled chiller and the cooling tower, circulating water pump, and pipeline, which requires careful investigation according to the installation diagram;

4. If the cooling performance of a water-cooled chiller that has been used for half a year or a year has decreased, there may be several problems: the heat exchanger of the water-cooled chiller is too dirty, and it is recommended to clean the heat exchanger (fin heat exchanger). Or shell and tube heat exchanger), and clean it regularly during subsequent use; the refrigeration system of the chiller leaks freon, it is recommended to find the leakage point, repair welding, and add refrigerant; it may be that the environmental temperature of the chiller is relatively bad. If it is too high or too low, the water-cooled chiller cannot meet the requirements. In this case, the requirement can only be met by choosing a larger water-cooled chiller.

In the face of water-cooled chillers with reduced cooling performance, if the user does not have professional maintenance personnel, do not handle it without authorization, but should contact the original chiller manufacturer to arrange professional technicians, or find professional maintenance near the factory For users with poor water sources, it is recommended to filter the water quality or do professional water treatment; in addition, users should do regular maintenance on the unit, which can not only ensure the normal operation of the unit.

Water chillers have been more and more widely used in all walks of life around us. Its main function is to provide industrial chilled water for equipment or products. The use of water-cooled water chillers to reduce the temperature not only improves production efficiency, but also reduces Cost of production. In the face of abnormal problems with water-cooled chillers, they must be dealt with in time, and attention must be paid to maintenance and cleaning in daily use, which also effectively improves the service life of the equipment.
