6.4.1.2 Minimum Equipment Efficiencies—Listed Equipment—Nonstandard Conditions 6.4.1.2.1 Liquid-Cooled Centrifugal Chilling Package Cooling Efficiency Adjustment. Liquidcooled centrifugal chiller packages not designed for cooling operation at AHRI Standard 550/590 test and rating conditions of 44.00°F leaving and 54.00°F entering chilled-liquid temperatures, and with 85.00°F entering and 94.30°F leaving condenser-liquid temperatures, shall have maximum full-load kW /ton (FL) and part-load cooling energy efficiency ( IPLV .IP) rating requirements, listed in Tables 6.8.1-3 and 6.8.1-16, adjusted using the following equations:
FL.IP adj = FL.IP/ Kadj PLV.IP adj = IPLV .IP/ Kadj
Kadj = A × B
