sir, we all know in refer system from evaporator slightly super heated vapour returns directly to compressor crankcase, not directly to the compressor suction side. from the crankcase compressor takes suction. why is that so? is it to eliminate risk of liquid refrigerant getting directly into the suction? or any other specific reasons? can you pls help?
Dear sir, to my knowledge the heated or expanded gas returns back to compressor suction but the during suction it overpasses to c/case as it is at a considerable high pressure which the piston rings fail to contain unlike in M/E or A/E where it is managed to be arrested by much higher extent against passing over to c/case side due to the carbon deposits which do the job almost like sealed rings which is not seen in A/C or Fridge compressors where there is almost nil carbon deposits.That's why the c/case in A/C or fridge comp are pressurised at same pr as suction pr which of course helps the comp protect from liquid being sucked.
Thank u sir, great explanation.
Glad you liked it
Thank you sir....
Excellent explanation....
Please upload more videos...
