PRESSURE DROPS,
EVAPORATOR
The following diagrams show the
values of the pressure drops in kPa,
on the basis of the capacity in l/h.
The operation field is defined by the
minimum and maximum values of the
curves, which indicate the limit of use
of the water side heat exchangers
(evaporators).
The pressure drops of the diagrams
are relative to the average water
temperature 10°C. The following table
shows the correction to apply to the
pressure drop when the average
water temperature varies.
9.2
PRESSURE DROPS,
CONDENSER
The pressure drops of the diagram
are relative to an average water
temperature of 50°C. The following
table shows the correction to apply to
the pressure drop when the average
water temperature varies.
