Re: 30GTN Chiller
Might be a stupid question but I will ask anyway.
Does this system have any form of hot gas bypass.
These are usually enabled during initial start-up?
If so could this be relevant?
Or are you saying that pressures are as expected when viewed with independant gauges.
There is definatly something wrong when a suction readout is higher than discharge.
With this in mind it is not likely to be the Expansion Valve.
Good one this keep us posted !
