Tw [°C] = Inlet water temperature
Ta W.B. [°C] = Inlet air temperature with wet bulb
Ta D.B.[°C] = Inlet air temperature with dry bulb
Pc [W] = Total cooling capacity
Ps [W] = Sensible cooling capacity
NB: The values in bold type indicate the rated value.
If sensible power values are above the total cooling capacity, this
means that cooling is carried out without dehumidification.
In this case, only sensible power values are considered.
The cooling outputs of the table are at maximum speed (maximum
air flow).
To determine the cooling capacity based on the speed (air flow),
the values shown in the table must be multiplied by the following
factors (k):
