Chillers are becoming more common in air-conditioning, industrial and aerospace applications and thus a chiller with a coefficient of performance (COP) greater than 2.2 is required, in order to meet the energy efficiency demands. If it is not available it may be assumed as For Natural Draft Cooling Tower D = 0.3 to 1.0 * C /100 For Induced Draft Cooling Tower D = 0.1 to 0.3 * C /100 The chilled water pump is a part of an overall chilled water system that often includes a chiller, piping, valves/fittings, Now lets look at how to calculate the cooling capacity of a chiller in imperial units.
