7 - AERAULIC CONNECTIONS
Aeraulic Connections
The unit must be installed inside the building, preferably in a technical room or a laundry room or a garage.
At any rate, it is always preferable to avoid installing the unit near bedrooms or in rooms that must be protected from noise.
Outdoor installation is prohibited, as well as installation in places subject to external weather.
Examples below refer to the AWHM-TDF 190/1.5-H31 version. For the AWHM-TDF 300/3.5E-H31 version, the expulsion and intake
connections are inverted.
INTAKE AND EXPULSION DUCTS (recommended)
Channelling the intake and expulsion through ducts allows the unit to function with air taken from outside the house. Heat is
extracted from the outdoor air, and used as a source for the heat pump.
Later this same air is expelled outside the building.
Therefore, unit operation does not cause an increase in heating requirements in the home. It is necessary to fit the system with
correctly sized pipes in relation to the available pressure head supplied by the unit.
INTAKE DUCTS (conditioned)
EXPULSION DUCTS (conditioned)
Installation with an intake duct and free expulsion is
recommended if there is a desire to use the air expelled by
the unit, cold dehumidified air (5-10°C colder than the
intake air), to cool the room.
The unit must be installed preferably in a room that does
not require heating, because the unit releases cold air into
the environment and it would increase the cost of heating
that room.
The unit must be installed in a room with a minimum
2
volume greater than 15m . The expulsion air flow must be
guaranteed and cannot be blocked. It is necessary that the
vents be correctly sized.
In this particular type of installation, the unit takes in air
from the room where it is installed, extracts the heat and
then expels that air outside the house.
The unit must be installed in a room with suitable
openings to allow the correct flow of air into the unit,
which would prevent the air pressure in the room from
falling. The unit must be installed in a room with a
minimum volume greater than 15m
