7. 1 COOLING AND INPUT
CAPACITIES

- "STANDARD VERSIONS"

- "HEAT PUMP VERSIONS IN COLD
MODE"
- "HIGH TEMPERATURE VERSIONS"
The refrigerating capacity yielded
and the input electrical capacity in
conditions other than rated conditions
are obtained by multiplying the rated
values (Pf, Pa) by the respective
correction coefficients (Cft, Cpa).
The following diagrams allow you to
obtain the correction coefficients to
be used for the various versions of the
devices, in cold mode; next to each curve
you can see the outside air temperature
to which it refers.
KEY:
Cf = Cooling capacity correction
coefficient
Ca = Input power correction
coefficient
N.B.
FOR VERSIONS Y with temperatures
lower than 4°C, contact the company
headquarters
FOR ∆T OTHER THAN 5°C
For the evaporator, the Tav.7.4 is
used to obtain the correction factors
of the cooling and input capacities.
To take into account the dirtying of
the exchangers, the relative dirtying
factors are used
