Hi Gents
Anyone know the McQuay maximum return water temp for these chillers? McQuay ALS F XE273.2. 990Kw cooling capacity.
I have increased plant supply water to 14*C with a return of 17*C. I have been told it can handel 20*C return water because of compressor liquid injection. Is this correct or am i getting duff info?:confused:
Talking to Mcquay tech line is like pulling teeth and getting conflicting stories.
I have converted a data centre to supply air control and have saved 20% on chiller loading, plant water has increased 4K to double the free cooling operational time. I will publish my findings later on.
Cheers guys
