The graphs allow to get the corrective factors to be applied to the nominal performances in order to obtain the real performances in
the selected operating conditions. For the "Operation limits" of the unit refer to the section limits.
The reference nominal condition is:
A7W45
(source : air in 7°C d.b. 6°C w.b. / plant : water in 40°C out 45°C)

HEATING performances
The standard performances refer to a 5°C temperature difference between the water entering and leaving the heat exchanger and to operation of the unit with all fans at
nominal or maximum speed. A 0.44 x 10

K/W fouling factor has also been considered with the unit installed at zero meters above sea level (Pb = 1013mbar).
NOTE
For air temperatures of less than 7°C, the heating capacity is declared without considering the effect of the defrosting, strictly correlated with the humidity in the
outdoor air.
