Hi all,
I have some compressors having the oil wash out of the compressor and then the compressor seizing up. It is on static cooling (non forced air) it has a condenser with fan but frozen shelves.
unit is on r290 and it has a danfoss compressor on, they doesnt seam to be much sub cooling and the compressor does get really, also the drier gets really hot when the ambiant is only around 18oc
Are the shelves supposed to be iced up? Is the compressor rated for low back pressure? Is your condenser spotless with fans running at full speed? is condensing unit outside or internal? Any pressures/temps?
have you checked super heat to make sure it not flooding
is this a new system or has it just started to have issues
Has the suction line been oil trapped or had a suction accumulator fitted. Is the condensing unit above or below the evaporator and how long is the suction
Line?
