We have already had a more detailed understanding of the industrial chiller through the previous introduction, but it seems that we have rarely heard of the refrigeration system of the chiller, so I will share this knowledge with you.
Our more common industrial chiller refrigeration system refrigeration system manifestations include the influence of exhaust or condensing pressure changes on the refrigeration system. If the refrigeration system is running at this time, its exhaust pressure will correspond to its condensing temperature, and the condensing temperature is related to all aspects of its cooling medium, so when testing the refrigeration system, it is necessary to detect the discharge Gas pressure as an important basis.
If it is found that the discharge pressure of the chiller is higher than the normal value, it means that there are some abnormal conditions, including small flow of cooling medium, high temperature of cooling medium, excessive refrigerant charge, large cooling load and shrinkage Open big and so on. However, if the exhaust pressure is lower than the normal value, it is possible that the compressor efficiency is low, the amount of refrigerant is insufficient, the cooling load is small, the opening of the shrink valve is small, and the filter is not dredged. All of these factors will trigger a piecemeal traffic change factor, so try to avoid it as much as possible.
For convenience, the evaporating pressure and condensing pressure of the refrigeration system are detected at the suction and discharge ports of the compressor. The purpose of detecting the suction and exhaust pressure of the refrigeration system is to obtain the evaporation temperature and condensation temperature of the refrigeration system, so as to obtain the operation status of the refrigeration system.
Maybe after reading these introductions, everyone is still a little vague about the refrigeration system of the industrial chiller refrigeration system, but it doesn’t matter, as long as you use it and pay more attention in time, you should be able to thoroughly understand its concept, maybe It will be of some help to everyone.
