PLANNING DATA
Temperature efficiency
Temperature efficiency for units with counterflow heat exchanger according to EN308 (dry).
Temperature efficiency EN308:
ɳ
t
= (t
supply air
-t
fresh air
)/(t
extract air
-t
fresh air
)
Capacity
Capacity of standard unit as a function of q
v
and P
t, ext
.
SFP values according to EN 13141-7 are for standard units with ISO Coarse >90% (G4) filters and no heating element.
SFP values comprise the unit´s total power comsumption incl. control.
Conversion factor:
Attention! The SFP values are measured and stated as a total value for both fans.
Nilan units are tested in accordance with the valid standards of accredited independent test institutes.
