GENERAL REMARKS
The principles of static, heat recovery ventilation (HRV)
In a Heat Recovery system, air is renewed mechanically
by being pumped into the living accommodation whilst bein
gextracted from the bathroom and kitchen areas.
Fresh air is fed into the dwelling via supply ducts and diffused
by grilles located in the living room and bedrooms.
1
Microwatt or standard fan motor unit:
responsible for the supply of fresh air and the extraction of
stale air whilst limiting energy consumption, particularly
with the microwatt version.
2 Highly efficient heat exchanger:
used to recover calorific energy from the air extracted.
Flat ductwork: facilitates the integration of the system
3
into the dwelling and reduces pressure losses.
Thermally-insulated network outside of heated area.
4 Distribution casing: Distributes balanced volumes into
each room. Facilitates the integration of the system into
a suspended ceiling void.

The 'used' air extracted via the grilles in high humidity rooms
is fed through a heat exchanger before being discharged into
the outside air. The heat exchanger can recover up to 90% of
the calories from the outgoing air to preheat the incoming air.

Supply grilles: Used to supply air to the bedrooms and
living room, these grilles can be fitted into walls or the cei-
ling and the air-jet can be adjusted.
6 Self-balancing extraction grille: Used to extract used air
and discharge it outside.
Controls: used to set the ventilator speed and displays
7
filter blocked warnings.
Fresh air inlet and used air outlet.
