10.2. HEATING CAPACITY AND
INPUT POWER
−
"HEAT PUMP VERSIONS"
The heating capacity yielded and the
input electrical capacity in conditions
other than rated conditions are
obtained by multiplying the rated
values (Pt, Pa) by the respective
correction coefficients (Ct, Ca).
The diagram allows you to obtain
the correction coefficients; in line
with each curve you will see the hot
processed water temperature to
which it refers, assuming a difference
of temperature between the
condenser inlet and outlet water
equal to 5°C.
The outputs are intended as net of
the defrosting cycles.
KEY
Ca:
Correction coefficient of
the input power.
Ct:
correction coefficient of the
heating capacity.
10.3. FOR
∆
t DIFFERENT FROM THE
RATED VALUE
For
∆
t different than 5°C to the water
consumption the Tab. 10.4.1. is used
for the correction factors of the
cooling and absorbed capacity.
10.4. FOULING
FACTORS
The performance levels indicated in
the table refer to conditions with
clean tubes, with a fouling factor = 1.
For other fouling factor values,
multiply the data of performance
table 10.4.2. by the coefficients given.
