Compressor Effieiency
I am wondering if there is any way you can test a compressor to see if it is functioning correctly. Not on the electrical side on the refrigeration side to see if it is pumping enough refrigerant though the system.
Hopefully i have explain this the correct way for you to understand.
Cheers

Compressor pumping test
- connect a compound gauge with compressor suction pipe
- close the compressor suction shut-off valve (should be very tight)
- Link out L.P. control switch.
- start the machine to pump down to below 24”Hg.
- If at least 18”Hg not achieved think valves are defective.
- If 24 Hg achieved stop compressor& monitor vacuum rise rate. Normal criterion for a new/re-manufactured compressor is not more than 10”/minute.
(This is only for reciprocating compressors)
