Ventilation and Treatment of Tertiary Air with High Energy Efficiency

According to RITE 2007, IT 1.1.4.2 Demand indoor air quality

Beginning

In buildings with other non-residential uses, in order to limit thermal losses, the most effective solution is to adapt air renewal flows to the actual occupation of the premises.
Indeed, the occupancy rate (frequency of use x fill rate) of premises such as offices or meeting rooms is very reliable.

How?

Using the “turnkey” solutions under the RITE:

• VISIOVENT (all or little ventilation)
• VARIVENT (proportional ventilation).

VISIOVENT
“All or little” ventilation with DIP presence detector

These solutions allow savings of up to 35 in air renewal flows.

	Beginning In in-occupancy, during a period of ventilation operation, the flow of the premises corresponds to 10 of the nominal flow, this flow commonly called “purge flow” is intended for the post or pre-ventilation of the premises. In occupancy the nominal flow rate is obtained thanks to presence detection. Nominal flow rates are determined by RITE regulations.
Please note that a watch must cut off the ventilation at night, but must be operational again at least one hour before the site is occupied.

VARIVENT
“Proportional” ventilation with CO2 catcher

These solutions provide savings that can be 70 in air renewal flows.

	Beginning In in-occupancy the flow rate corresponds to a 10 of the nominal flow rate, as in the “all or little” system. In variable occupancy the air renewal flow varies according to the number of occupants [depending on the rate of carbon dioxide (CO_2). In maximum occupancy, it passes to the nominal flow rate. Nominal flow rates are determined by RITE regulations.
Please note that a watch must cut off the ventilation at night, but must be operational again at least one hour before the site is occupied.

SCHEME OF PRINCIPLESMONOZONA: The fan controls a single location (example: meeting room). In “all or little” solution the fan must ensure 2 flow rates (minimum flow rate and nominal flow). In “proportional” solution, the fan speed must be adapted to the actual occupancy conditions of the premises. MULTIZONE: the fan controls several premises (e.g. meeting room + office). With this configuration, which can be “all or little” or “proportional”, the catchers or probes act on the terminals (mouths, all or little records, proportional records …) making the fan adapt to variations in demand.
