I have a York YK chiller that has had chilled water lines piped around wrong way, traditionally return water from field enters evaporator at bottom of evaporater travels along bottom half tubes flooded with liquid refrigerant and as such heat is transfered, With leaving ch water out at top (2pass).
I am told by experts that effciency of chiller will be only marginally effected, but my concern is stability of gas entering impeller causing stall or surge??, centrifugal compressors are selected for certain flow rates and as such would rely on correct rate of evaporation as per evap design.
I beleive with warm water entering at top tubes will cause massive boiling effect (more than usual), can any boffins out there give me some facts and figures that I can use to substanciate or discredit my theroy
