If the cold storage project needs to be shut down for an extended period, the refrigeration system must be shut down and the refrigeration equipment must be taken out of service for a long time. The refrigerant must be collected in the system's liquid receiver or condenser, and the cooling water in the water-cooled condenser must be drained completely. Zhonglu Refrigeration will introduce this in detail for you!
1) Close the liquid outlet valve of the accumulator or condenser to prevent the refrigerant from being supplied to the evaporator through this point;
2) Short-circuit pressure relay
3) Close the relevant valves
4) Start the compressor until the suction gauge pressure approaches 0 MPa, then quickly close the exhaust stop valve and simultaneously cut off the power supply;
5) If the refrigeration equipment is a water-cooled condenser, the cooling water inside the condenser should be drained to prevent water accumulation and freezing inside the pipes, which could lead to pipe cracking when the temperature is too low in winter;
6) Unplug the power plug from the socket.
After all that Attega has said above, I wonder how much you have understood. If you have any other questions, please feel free to contact us
