Evaporative Condenser Formulas:

Total Heat of Rejection (THR):

Open Compressors:
THR_BTU/HR = Evaporator Capacity_BTU/HR + Compressor BHP X 2545

Hermetic Compressors:

THR_BTU/HR = Evaporator Capacity_BTU/HR + Compressor KW X 3415

Evaporation Rate_GPM = THR_BTU/HR / 500,000

Bleed Rate_GPM = Evaporation Rate_GPM / (Cycles - 1)


Make-up_GPM = Evaporation Rate_GPM X [Cycles / (Cycles - 1)]
