How to use the screw ammonia refrigerator, how to start it, and what is the oil pressure?

The refrigerator is remotely controlled, so you can switch between cooling and heating according to the mode.

Power on-there is a switch button on the remote control, which will be turned on when pressed, and turned off when pressed.

The oil pressure depends on the amount of refrigerant in the compressor. The high pressure of refrigerant should not be higher than 350Pa, and the low pressure should be around 46Pa.

Oil pump or compressor overload

Due to the high actual production load, this failure is unlikely to lead to compressor overload. When this kind of fault occurs, the most obvious phenomenon is that the motor current obviously rises beyond the normal value. Therefore, we can check the electrical system first, consider the production load, increase the number of compressors to start, reduce the load of faulty compressors, and cooperate with electrical troubleshooting.
