A chiller extracts heat from a process or building and rejects it to a condenser, providing cooling capacity measured in kilowatts (kW). The efficiency of this heatβtransfer cycle is expressed by the Coefficient of Performance (COP), which compares useful cooling output to the electrical energy consumed.
The COP is dimensionless and typically ranges from 3 to 7 for modern waterβcooled chillers. A higher COP indicates that more cooling is delivered per unit of power, reducing operating costs and environmental impact.
Designers use the COP together with the required cooling load to size compressors, pumps, and ancillary equipment. Accurate calculation ensures the system meets demand without oversizing, which would waste capital and energy.
