Analysis of the Reasons for the Decrease of the Cooling Capacity of Water-cooled Chiller
There are many ways to classify industrial chillers, one of which is divided into water-cooled and air-cooled chillers based on different cooling methods. Both of them have their own advantages and disadvantages. The main reason is that the air-cooled chiller is easy to install, while the water-cooled chiller can have a larger cooling capacity and a higher energy efficiency ratio.
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, tire manufacturing plants, and electroplating plants that require very large cooling capacity. , Airports, food factories and other industries.
When a water-cooled chiller is in use, it needs to be equipped with a cooling tower and a water pump for heat dissipation to provide circulating cooling water. The installation is a bit more complicated than an air-cooled chiller. 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. A part of the factor is that the water source used by the water-cooled chiller has impurities, which after a long period of time accumulates and adheres to the pipes between the various equipment, resulting in a small water flow. Therefore, it is necessary to clean the pipes between the equipment;
2. As far as entering the chiller factory, all chillers will undergo performance testing before leaving the factory to ensure the normal operation of the unit. If there is a problem that the indoor temperature cannot be lowered during the first use, it may be that the water-cooled chiller is configured incorrectly;
3. The temperature of the cold water chiller cannot be lowered when the cold water chiller 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 needs to be checked carefully 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. 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 experienced maintenance personnel, do not handle it without authorization. Instead, you should contact the original chiller manufacturer to arrange for experienced technicians, or find someone near the factory. For users with poor water sources, it is recommended to filter the water or do experienced 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. Using 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 of 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.
