Heat Recovery
As mentioned in the above
section at Page 3.03, a fan
produces an air flow that
cools both the oil and the
compressed air, heating
up when it passes through
the cooler.
The recoverable heat rep-
resents about 100% the
installed power in the AC
6000 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 Section on “TECHNICAL DATA ”attached to this manual the
values required to realize that which is mentioned above are indi-
cated.
