COOLING CAPACITY
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 tem-
perature 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 mini-
mum 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.
Key:
Tw [°C]
= Inlet water temperature
Ta W.B. [°C]
= Inlet water temperature with wet bulb
Ta D.B. [°C]
= Inlet water 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 cooling capacities of the table must be multiplied by the following corrective factors:
