    Just a rule of thumb. For a 2 pass(supply and return on the same end of barrel) 10 deg chiller about 2gpm/ton. Estimate by pipe size. Use pump data.

    2 Pipe ?

    DMJacin- I need a clarification when you say a 2 pipe system; Do you mean that the same 2 pipes carry chilled water when it's hot out and heating hot water when it gets cold or do you mean there are only 2 pipes for chilled water to the hotel rooms all year long. There were many manufactures that have gone by the way side since 1968 (43 years ago) I'm sure without looking you have plugged coils and non-operating valves throughout this system. As you are saying Westinghouse the for runner of McQuay Inwould assume the chiller is R-12 and dates back to 1968 also.-GEO
    Once in a while everything falls into place and I am able to move forward, most of the time it just falls all over the place and I can't go anywhere-GEO

    Those Westinghouse chillers were designed to last forever, well it seemed like forever. The older guys from mcquay remember them.
