CCF: Capacity correction factor
WFCF: Water flow 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 maintain the same temperature
difference as that which would be obtained without glycol. The pressure drop correction factor takes into account
the different flow rate obtained from the application of the flow rate correction factor.
