  • How to Calculate Chiller Efficiency | Hunker

    How to Calculate Chiller Efficiency , The formula for total heat removed in a chiller installation is h = 500 X q X dt where h = total heat removed in Btu/hr, q is the chilled water flow rate in gpm, and dt is the chilled water's total temperature differential Substituting, h = 500 X 40 gpm X 24 deg-F = 480,000 Btu/hr
