FCGPF = Cooling capacity correction factor.
FCGPT = Heating capacity correction factor.
FCGPA = Input power correction factor.
FCGQ = Water flow correction factor.
FCGDP = Pressure drops correction factor.
The cooling capacity and input power correction factors take into account the presence of glycol and the different evaporation temperature.
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 such a way as to maintain the same Dt 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.
