CONDENSER PERFORMANCENotes:1. The following Condenser Pressure Drop values are based on the fouling factor of 0.044 m2 K/kW.2. Water flow rate can be calculated using the formula below:

Water Flow (l/min)= TC + Power Input

Water Temp. Rise x 0.07

Where:TC = Total cooling capacity (kW)Power Input = Compressor power input (kW)Water Temp. Rise = Cond. leaving water temp. - Cond. entering water temp. (0C)

Conversion Factors : FTWG = PSI x 2.31 = BAR x 33.5 = kPA x 0.33

USGPM = l/min x 0.2642
