COOLING POWER YIELDED
Key:
Tw [°C] = Inlet water temperature
Ta B.U. [°C] = Inlet air temperature with wet bulb
Ta B.S. [°C] = Inlet air temperature with dry bulb
Pc [w] = Total cooling capacity
Ps [w] = Sensitive cooling capacity
Qv [m
3
/h] = Air flow rate
H = maximum speed
M = medium speed
L = minimum speed
NB: The yield values marked in bold indicate the nominal value.
To calculate the cooling capacity yielded, the values shown in the
table must be multiplied by the corrective factors referred to
the different speeds.
Sensitive yield values greater than the total yield indicate that
cooling occurs without dehumidification.
In this case take into account the sensitive yield values only.
The table shows the sensitive and total cooling capacities at
maximum speed depending on the temperature of the water
entering, of its heat drop and temperature of the air with dry
bulb and wet bulb respectively for sensitive yield and total yield
for standard coil versions. The performances at medium and
minimum speed are obtained by multiplying the values in the
table by the corrective factors indicated for each speed.
NB: The yield values marked in bold indicate the nominal
value.
The cooling capacities of the table must be multiplied by the following corrective factors:
