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

Release time:


When the water-cooled chiller is in use, it needs to be equipped with a cooling tower and a water pump to dissipate heat to provide circulating cooling water. The installation is more complicated than the air-cooled chiller. The next thing I want to introduce to you is the factors that lead to the decline of the cooling performance of the water-cooled chiller. Let's take a look.

1. Part of the factor is that the water source used by the water-cooled chiller has impurities, which is accumulated for a long time and attached to the pipeline between the various devices, resulting in a small water flow. Therefore, the pipeline between the equipment should be cleaned;

2. As far as the cold water machine factory is concerned, all cold water machines will be tested for performance before leaving the factory to ensure the normal operation of the unit. If the indoor temperature cannot be lowered in the first use, it may be that the water-cooled chiller is not matched;

3. The temperature of the cold water chiller cannot be reduced for the first time. Another reason is that there is a small problem between the water-cooled chiller and the cooling tower, circulating water pump and pipeline, which needs to be carefully checked according to the installation diagram;

4. If the cooling performance of the water-cooled chiller that has been in use for half a year or one year decreases, there may be several problems: the heat exchanger of the water-cooled chiller is too dirty, so it is recommended to clean the heat exchanger (fin heat exchanger or shell-and-tube heat exchanger) and clean it regularly during subsequent use. Freon leaks in the refrigeration system of the chiller. It is recommended to find out the leak point, repair welding and add refrigerant, too high or too low, the water-cooled chiller cannot meet the requirements. In this case, the requirements can only be met by choosing a larger water-cooled chiller.

Faced with the decline of cooling performance of water-cooled chillers, if users do not have professional maintenance personnel, they should not deal with it without authorization. Instead, they should contact the original chiller manufacturer to arrange professional technicians or find professional maintenance points near the factory for treatment. 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 work for the unit, not only can ensure the normal operation of the unit.

Chiller has been more and more widely used in all walks of life around us, its main role is to provide industrial chilled water for equipment or products, the use of water-cooled water chiller to reduce the temperature, not only improve the production efficiency, but also reduce the production cost. In the face of abnormal problems in water-cooled chillers, we must deal with them in time, and pay attention to maintenance and cleaning in daily use, so as to effectively improve the service life of the equipment.
