Heating Capacity And Input Power; For Δt Different From The Rated Value; Fouling Factors - AERMEC WRL 200 Technical Manual

9.4. HEATING CAPACITY AND INPUT
POWER
The heating capacity yielded and the input
electrical capacity in conditions other than
rated conditions are obtained by multiplying
the rated values (Ph, Pa) by the respective
correction coefficients (Ch, Ca).
The diagram allows you to obtain the correc-
tion coefficients; corresponding to each curve,
the temperature of the hot processed water
referred to is reported, assuming a difference
in water temperature between the input and
output of the condenser equal to 5°C/10°F.
KEY:
Ph: Heating capacity
Pa: Input power
Ch: Heat capacity correction coefficient
Ca: Input power correction coefficient
9.5. FOR ΔT DIFFERENT FROM THE
RATED VALUE
For Δt different from 5K, refer to Tab.
"∆t DIFFERENT FROM NOMINAL (∆t 5)" for
the cooling capacity and input power correc-
tion factors.

FOULING FACTORS

The performance levels indicated in table:
"FOULING FACTOR [K*M ]/[W]" refer to con-
2
ditions with clean tubes, with a fouling factor =
1. For values different from the fouling factor,
multiply the values in the performance table by
the reported coefficients.
