Briefly discuss the reasons why the temperature of Dongguan water chiller cannot drop: Dongguan water chiller, the reason why the temperature cannot drop: Dongguan water chiller has been increasingly widely used in various industries around us. Its main function is to provide industrial chilled water for equipment or products. The water temperature requirements can be adjusted according to user needs, and its accuracy can be accurately controlled at ± 1 ℃. However, during the use of the unit, some users may encounter a temperature drop that cannot be reduced. Let's analyze it together.
Dongguan water chillers, including water cooled box type water chillers, water cooled open type water chillers, and water cooled screw type water chillers, need to be equipped with cooling towers and pumps to dissipate heat to provide circulating cooling water when they are used. Installation is a bit more complex than air cooled water chillers, and there are many factors that cause the temperature of the water chiller to not drop, such as:
1. For Daheda Water Chiller Company, all Dongguan water chillers undergo 100% performance testing before leaving the factory to ensure normal operation of the units. If this problem occurs during initial use, it may be due to the incorrect configuration of the Dongguan water chiller;
2. Another reason why the temperature of Dongguan water chiller cannot drop during initial use is that there is a small installation problem between the water chiller and the cooling water tower, circulating water pump, and pipeline, which requires careful troubleshooting according to the installation diagram;
3. If this situation occurs with a water chiller that has been in use for half a year or more, it may be caused by the following issues:
The heat exchanger of a water cooled chiller is too dirty. It is recommended to clean the heat exchanger (fin heat exchanger or shell and tube heat exchanger) and regularly clean it during subsequent use;
The refrigeration system of the water chiller leaks freon. It is recommended to find the leakage point, repair welding, and add refrigerant;
C. It is possible that the ambient temperature of the water chiller is relatively harsh, too high or too low, resulting in the water chiller being unable to meet the requirements. In this case, only a larger water chiller can be selected to meet the requirements;
4. It may be that the water source used has impurities that have accumulated and adhered to the pipes between various equipment over a long period of time, resulting in a small water flow. Therefore, it is necessary to clean the pipes between various equipment;
If you encounter any of the above issues, if the user's factory does not have professional maintenance personnel, you should not handle them without authorization. Instead, you should contact the water chiller manufacturer to arrange professional technical personnel, or find a professional maintenance point near the factory to handle them; For users with poor water resources, it is recommended to filter the water quality or conduct professional water treatment; In addition, users should perform regular maintenance work on the unit, which not only ensures the normal operation of the unit, but also extends the service life of the water cooled chiller
