Common Faults and Solutions of Summer Chillers


Most of the country has entered a hot summer day, and industrial chillers in many factories have ushered in the peak of refrigeration. The refrigeration equipment is frequently operated, and it is likely that such small faults will occur. Today, An Yida will introduce some simple and practical knowledge of the operation and maintenance of the chiller. I hope it can help you solve the problem in a timely manner, which will not delay production and save unnecessary maintenance costs for refrigeration equipment.


1. When the high and low pressures of the water chiller are higher than the normal normal pressure, a situation is poor heat dissipation, especially when the ambient temperature is relatively high, which often leads to worse heat dissipation. The cause of this failure is generally a clogged heat sink , Dirty, the cooling fan speed is not enough, etc., try to clean the cooling fins of the condenser. This is an important reason for the high-pressure alarm of the chiller in summer. Many customers put a lot of debris in the chiller machine room when the weather is not hot, which seriously affects the heat dissipation of the machine. It may be fine at the time, but when the weather is hot It is easy to cause high-pressure alarm of the unit and affect the normal operation of the unit.


2. The energy efficiency ratio of the water-cooled chiller unit becomes worse, and the cooling capacity drops. One situation is that the cooling water system has a dirty blockage, which is caused. At this time, it is only necessary to clean the cooling water tower and replace the cooling water to solve the problem.


3. When the chiller is working, the pressure gauge shakes, indicating that there is moisture in the system. At this time, the vacuum needs to be evacuated again for no less than one quarter of an hour. If necessary, it is best to change the drying filter to completely remove the moisture in the refrigeration system. However, vacuum replacement of the drying filter is a very professional maintenance skill, and it must be operated by relevant professionals.


In fact, to make the chiller more stable and efficient operation, it is best to cooperate with professional refrigeration equipment companies, let them do regular professional maintenance, so as to ensure the stable and efficient operation of the chiller.
