Cooling capacities are referred to high speed.
To obtain values for other speed, multiply the values read by following factors:
MOD. FCW 41
Medium speed
total capacity 0.91
sensible capacity 0.88
Minimum speed
total capacity 0.79
sensible capacity 0.75
Water flow rate as at maximum ventilation speed;
Tw [°C] = Inlet water temperature
Ta w.b. [°C] = Inlet wet bulbe air temperature
Ta b.s. [°C] = Dry bulbe air temperature
Pc [W] = Total cooling capacity
Ps [W] = Sensible cooling capacity
NOTE: Values of capacity in bold face refer to nominal value.
Values of sensible capacity higher than values of total capacity mean that cooling is without dehumidification in this case
consider only the values of sensible capacity.
