In the course of operation, the cold water cooler in the industry does not appear to be cooling, and there is no alarm prompt, so that the operator can not start, do not know what causes this problem. East Star to do an example of this phenomenon, hoping to help the majority of users, as soon as possible to solve the problem, to restore the daily use of cold water.
       According to the maintenance of East Star Refrigeration oral, small series will not be cold water chiller and no warning signs of the reasons for the analysis summarized as follows:
       1, refrigerant R22 is not enough, that is, we often say freon. In the chiller operation process, the liquid refrigerant in the evaporator to absorb the heat from the water stop and start after evaporation, compressor and expansion valve throttling, it becomes a low-temperature and low-pressure refrigerant into the evaporator loop to continue. If the use of time is too long refrigerant will be volatile, and then affect the cooling effect. There is also a reason for the leakage of refrigerant, which is not enough to affect the cooling, therefore, cold water operator should observe whether the refrigerant is enough. In case of leakage of refrigerant, it is recommended to contact the cold water machine manufacturer arrange leak trap, adding enough refrigerant.
       2, condenser is not cleaned for a long time, condenser is one of the main components of the chiller. Most of the cooling water contains calcium, magnesium ions and acid carbonate. When cooling water passes through the metal surface, the formation of carbonate. In addition, the dissolved oxygen in the cooling water will cause metal corrosion, rust. Due to the formation of rust scale, the heat transfer effect of the condenser is decreased, and the pipe is blocked when the fouling is serious. Therefore, it is recommended that the condenser be cleaned once every six months.
       3, dry filter plugging. When the filter is blocked, it will affect the heat transfer effect of the condenser, and then the whole machine can not work well. Therefore, it is necessary to check and clean the filter regularly.
       4, excessive impurities in the water, attached to the inner wall of the pipe, resulting in insufficient water supply, thus affecting the cooling effect. Therefore, the water quality is poor, it is recommended to do water treatment works or regular cleaning and replacement of water pipes in order to ensure the normal operation of cold water.
       In addition, chiller selection must be accurate. Models are not in place, the same will not meet the needs of the cooling effect. I suggest that the majority of users in the purchase of water chiller, cooling capacity and other parameters will need to be provided to producers of cold water machine, cold water machine, discuss and draw the model, determine the installation scheme of cold water machine, achieve the expected effect of the refrigeration, to improve production efficiency.
