7 major faults lead to refrigeration unit air pressure is too low how to do?

　　In the pharmaceutical, food, industrial, fresh electricity and other industries in the refrigeration unit more core equipment, today we take the pharmaceutical cold storage, for example, in recent years, with the continuous development of China’s pharmaceutical industry, as well as production, logistics and transport requirements continue to improve, the refrigeration industry market ushered in the development of space for the installation of the cold storage of the demand for more and more.

　　It is understood that many users in the process of using the pharmaceutical cold storage, no major faults, small faults will occur, then you need to understand the common equipment failures and the corresponding solutions to ensure that the refrigeration unit to continue to run.

　　So the refrigeration unit suction pressure is too low what causes? Users and how to solve it? The following is a brief introduction to the common faults and their solutions.

　　Failure 1: refrigerant filter clogging, refrigerant filter has an important filtering role, should be kept clear, if the phenomenon of clogging needs to be regularly cleaned or replace the filter.

　　Failure 2: improper adjustment or failure of the expansion valve. If this phenomenon occurs, it is recommended to immediately adjust the correct or troubleshooting, if necessary, replacement.

　　Failure 3: condenser refrigerant liquid outlet valve is not fully open. It is reported that the condenser refrigerant liquid outlet valve is not safely opened, the refrigeration unit will produce suction pressure is too low. The valve should be fully opened at this time.

　　Failure 4: Insufficient water through the evaporator. This situation will also make the cooling capacity drop and the cooling effect is not good. Users should check the water pump and water valve in time.

　　Failure 5: Excessive lubricating oil circulates in the chiller refrigeration system. If you find a lot of lubricating oil in the refrigeration system, this time you should find out the reason and reduce it to the appropriate value.

　　Failure 6: When the inlet water temperature of the evaporator is too low, the cooling effect is not good. The inlet water temperature setting should be increased.

　　Failure 7: Insufficient water passing through the evaporator. This situation will also make the cooling capacity drop and the cooling effect is poor. Users should check the water pump and water valve in time.
