Should the refrigerant be released when the screw chiller changes the freezing oil?

To understand this problem, we must first understand the mechanism of the screw chiller. Because the screw chiller is a relatively large-scale refrigeration equipment, it is filled with more refrigerant, and the future maintenance problems will be taken into consideration during the production. If the refrigerant is released as soon as it is repaired, it not only wastes but also increases the maintenance cost. How to recycle refrigerant during maintenance.

We know that in general screw chillers, angle valves are installed at the condenser outlet; in addition, screw compressors also have exhaust valves. We can close the corner valve below, open the exhaust valve, and start the unit. At this time, we have to look at the low voltage meter. When the pointer is going to zero, immediately turn off the power and the machine stops running. This way most of the refrigerant is stored in the condenser. When the repair is completed, just release it.
