Trane Chillers
Trane Chillers
(OP)
Does anybody have maintenance experience with Trane's highest efficiency R-123 chillers? I'm on a new construction project where the client has one option of going with a slightly reduced chiller efficiency, or a "best" chiller efficiency which has different (possibly more) condenser and evaporator tubes, which unfortunately also causes a higher pressure drop across the condenser and evap. Preliminary calcs have shown both options would be about equal operating cost (the lower efficiency unit has lower pumping costs...). Any advice here? Thanks..





RE: Trane Chillers
you can select the chiller which has relatively lower working pressure
(for long compressor life and lower refrigerant leakage)
RE: Trane Chillers
have u looked at the trane website and studied
their proposal to use 2usgpm/ton for condenser
water flow? over varying weather conditions
this might be interesting option.

ps we also ask for max efficiency but get low
pressure drops--bigger shell and more tubes.
