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.

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)
