Condenser load for water cooled chillers
Condenser load for water cooled chillers
(OP)
Through my experience, the condenser section of a chiller is always larger and thus has more gpm and load. Is it a general rule of thumb that the condenser load in tons is always 25% greater than the evaporator load in tons? Is their a standard to this? At my plant which has 500-Ton, 1000-Ton, and 2000-Ton chillers the design condenser water gpm is 25% greater than the chilled water gpm. Just curious if this is a standard for all water cooled chillers...





RE: Condenser load for water cooled chillers
I'm looking at one right here, though, with 0.56 kW/Ton, 10°F delta T condenser and 15°F delta T on the evaporator. Condenser water flow is 3250 GPM and evaporator flow is 2000 GPM, so condenser is 63 percent greater than evaporator.

The "rule of thumb" is that the amount of compressor work is readily available in the chiller manufacturer's technical data.

Second law of thermo, heat rejected cooling the water will be larger than the cooling effect, ie, entropy increases......condenser
