Key::
FcGPf =
Correction factor of the cooling
capacity
FcGPa =
Input power correction factor.
FcGDpF (a) =(Evaporator) pressure drop
correction factor (evaluated with an
average temperature of -3.5 °C)
FcGDpF (b) = Correction factor of the
pressure drops (average temperature =
0.5 °C)
FcGDpF (c) = Correction factor of the
pressure drops (average temperature =
5.5 °C)
FcGDpF (d) = Correction factor of the
pressure drops (average temperature =
9.5 °C)
FcGDpF (e) = Correction factor of the
pressure drops (average temperature =
47.5 °C)
FcGQF =Flow rate (evap) correction
factor mean temperature
= 9.5 °C)
FcGQC =Flow rate (condenser) correction
factor mean temperature
= 47.5 °C)
The water flow rate and pressure drop
correction factors must be applied
directly to the data obtained for operation
without glycole.
