11. DESUPERHEATER
The heating capacity that can be
obtained from the desuperheater is
obtained by multiplying the nominal value
(Pd) shown in table 11.1.1 by a suitable
coefficient (Cd).
The diagrams will give you the correction
coefficients to be used for the chillers in
the various versions; next to each curve
you can see the outside air temperature
to which it refers.
11.1. PRESSURE DROPS
The NS models with the desuperheater
can have, depending on the sizes, up
to three
desuperheater (arranged paral-
lel to each other
NOTE
THE INSTALLER IS RESPONSIBLE FOR THE
HYDRAULIC PARALLEL.
NOTE:
the characteristics of the desuperheat-
ers and the pressure drop curves are
shown below.
For processed water temperatures dif-
ferent from 50°C, the result obtained is
multiplied by the correction factor that
can be obtained from Table 11.1.1.
The nominal value refers to:
air temperature ................................ 35°C
water at the desuperheater ............ 45°C
∆t ............................................................ 5°C
