Analysis of 10 major failure phenomena commonly seen in refrigeration equipment maintenance
2019-07-05
1. The exhaust gas temperature of the refrigeration system is too low: The low exhaust pressure is mainly caused by the small or even stop flow of the refrigerant in the refrigeration system. The exhaust pressure is too low, although the phenomenon is manifested at the high pressure end, but the cause is mostly caused by the low pressure end. Common reasons for low exhaust pressure: 1) T...
