HIGH PRESSURE
PUMPS
The heating capacity that can be obtai-
ned from the desuperheater is calcula-
ted by multiplying the rated value (Pd),
indicated in the table below the dia-
grams, by a suitable coefficient (Cd).
The diagrams allow the correction
coefficients to be used for the various
versions of chiller to be calculated; the
external air temperature referred to is
indicated in correspondence with each
curve. The pressure drops you see in
the table do not include the filter drop,
whose curve is indicated in table TAV
9.3.
The nominal value refers to:
air temperature
produced water temperature
NOTE
in the models with heat pump the desu-
perheater must be intercepted when
the heat pump is operating, otherwise
the guarantee will not be valid.
For chilled water production at tempe-
ratures other than 7°C or for evapo-
ration temperatures other than 5°C,
use the correction factors in the table
provided, as well as the ones obtained
from the graphs.
