Cooling tower coefficient of performance
Webthe cooling tower performance at conditions which are not otherwise available. PDAP, the Performance Data Analysis Program, is used to find the Merkel coefficient (KAV/L) for the cooling tower that best fits the available cooling tower data. A number of improvements have been incorporated into the Webficient of performance (COP), which is defined as useful thermal energy output (i.e., chiller load) divided by heat input. COP is a unit-less number and does not include energy consumed by pumps, fans, or other ancillary components. COP values for single stage chillers are less than one, and COP values for two
