High-Performance HVAC | WBDG - Whole Building Design Guide

Large and medium-sized air-cooled electric chillers have 0.95-0.85 kW/ton (COP of 3.7 to 4.1). Similar water-cooled electric chillers have 0.8-0.7 kW/ton (COP of 4.4 to 5.0). Lower values such as 0.6-0.5 kW/ chillers (COP of 5.9 to 7.0) may indicate energy efficient equipment but part-load performance should also be examined.
