What are the causes of high internal pressure in the chiller? I have summarized the following points:
If the chiller is used for a long time, for example, say a few months or several years, so that if the water quality of this area is the kind of simple scale water quality, there will be a lot of scale. These harmful substances are gathered on the inner wall of the condensing pipe. If the quality of these harmful substances is more than enough, the working efficiency of the cooling cycle system of the chiller will be greatly reduced, and the internal pressure of the chiller may be too high. Therefore, the control of good treatment is to do on time to the chiller requirements of clean care, cooling water system and condenser should be quickly washed, and the filter should also be frequently changed.
The internal pressure of the chiller is too high, or it may be the cooling water system that appears on the water-cooled chiller, or the cooling water valve is not opened, or it may cause cooling because of other reasons, and it cannot supply the circulating cooling water to the chiller properly, so the natural internal pressure is too high.
High chiller pressure has great influence, find out the cause of the medicine. If the chiller is well used, why will the pressure be too high? This is the time to check whether the refrigeration system pipeline congestion. The obstruction is probably due to the large amount of impurities in the refrigeration system. Also, it is necessary to check whether the refrigerant is charged in large quantities. If a large amount of refrigerant is equally important, once a large amount of refrigerant condition is found, should immediately release surplus refrigerant.
