Hey guys, I have a compressor doing something I have not seen before. Granted I have only been in the field for 5 years
I have a York split system with a scroll compressor. Two TXV and no hot gas bypass.
The unit was not cooling well, 67 deg leaving air temp. I checked the pressures and had a 90 suction pressure and only 225 head pressure. My outdoor temp was a lil over 90deg. Superheat was 40 and subcool was 15. Amp draw was running at the listed fla of 9.5.
Im in Louisiana and this unit was working fine before the hurricane. A day after the power was restored to the building the unit starts going nuts. I did add some gas to the system to see if my head pressure would come up. It did eventually but by the time I got it up t 275 the compressor went out on internal overload.
I also checked my TXVs both were slightly sweating on the leaving side of the TXV going into the evap coil.
ATM I am thinking I have a compressor problem. I dunno, I'm not used to seeing high suction and low head pressures.
