HEAT RECOvERy
As mentioned in above section on Page 3.03, a fan
produces an airflow that cools both the oil and the
compressed air, heating up when it goes through the
radiator.
The recoverable heat represents about 100% of the
power installed in the BLADE 15÷22 Series machines.
The heat produced can be conveniently recovered and
used to heat rooms.
Any duct should be adequately sized and, if necessary,
shaped in such a way to allow for a correct use during
Winter and the output of hot air during Summer. The
duct to recover/output hot air should be designed by
a competent engineer and should limit the load loss at
approximately 20 Pa. If the duct offers greater resistance,
an auxiliary extractor should be used to prevent any
overheating of the machine.
As an example, a duct with a higher or equal section
to the coming out of the machine (the output grid on
those versions equipped with a soundproof case), made
up of some 10 m of straight duct and two 90° elbows
properly connected, allows the maximum tolerated
limits to be maintained. However, it should be noted
that 10 Pa increase corresponds to some 2-3°C increase
in operating temperatures. As for the recoverable heat,
it should be noted that 1 kW of installed power allows
for the heating up a volume of about 30 cubic meters by
1 k (1 kW = 860 kcal/h).
In the technical data sheets attached to this manual
the values required to realize that which is mentioned
above are indicated.
