CCF: Capacity correction factor
IPCF: Input power correction factor
WFCF: Water flow rate correction factor
PDCF: Pressure drops correction factor
The water flow rate and pressure drop correction factors are to be applied directly to the values given for operation without
glycol. The water flow rate correction factor is calculated in order to get the same temperature’s difference that would be
obtained without glycol. The pressure drops’ correction factor takes into account the different water flow rate obtained from the
application of the water flow rate correction factor.
