Compressor Effieiency

[ferret82]

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.

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)
