10 Ton Scroll Compressor, R-22 AIR Conditioner
Suction: 51 P.S.I. Discharge: 200 P.S.I.
Condenser water in :75 Degrees
Air Temp entering evap coil :74 Deg
Evap Coil Clean, good air flow across coil
14 Degree :split air across evap coil ( This delta T is normal for these units)
New Power head on expansion valve
I throttled down on the TXV
Superheat measured at suction line feeler bulb : 20 Degrees
I may be overcharged. The suction line and half compressor are really sweating back
There is good amount of foam in the oil sight glass
I gather there is liquid boiling off in the External Equal. Line
Why would the suction pressure be so low?
