During operation, the heat pump tends to lower the room tem-
perature if the air ducting is not to the outside.
A suitable protection grille must be installed at the air extrac-
tion pipe to the outside to prevent any foreign bodies from
entering inside the equipment. To ensure maximum product
performance, the grille must be selected from those with low
pressure loss.
To avoid the formation of condensation water: insulate the air
extraction pipes and the ducted air cover connections with a
steam-tight thermal covering of adequate thickness.
Install silencers if deemed necessary to prevent noise due to
the flow. Equip the pipes, wall outlets and connections to the
heat pump with vibration-damping systems.
6.3.1 Special installation
One of the peculiarities of the heat pump heating systems is
that these units considerably lower the air temperature, gen-
erally expelled to the outside of the house. As well as being
colder than the ambient air, the expelled air is also completely
dehumidified, therefore the air flow can be returned inside for
the summer cooling of specific rooms or areas.
Installation provides for splitting of the extraction pipe, which is
fitted with two dampers ("A" and "B") for directing the air flow to
the outside (fig. 14) or the inside of the house (fig. 13).
