Aereco - Model VMX -Demand Controlled Ventilation System for Tertiary Buildings
The VMX is a unique intelligent ventilation system for non-residential sector (restaurants, schools, offices, meeting rooms…). This system is easy to install both in the new built and the refurbishment buildings. The VMX automatically modulates the ventilation on the basis of information received from the detectors that measure CO2 concentration, movements or detect presence. Thus, the air supply and exhaust flow rates are then matched to the true needs of the rooms functioned of the occupancy, reducing thermal losses and optimising electrical fan consumption. The VMX system is an affordable solution conciliating energy performance, indoor air quality and acoustic comfort that enhances rooms’ occupant comfort.
- Innovative system that modulates ventilation flow rates matching the flow rate to needs.
- Maintenance is light and easy: reporting of information about the condition of the system with an interface of control.
- Thermal, aeraulic and acoustic comfort for the occupants.
- Savings on the electrical energy consumption of the fans.
- Energy savings on heating or air-conditioning.
- Proven reliability, with thousands of systems already sold in France.
- Excellent indoor air quality at all times.
- System simple to install: only two wires on most of the components.
- Open and open-ended system: it can be connected to other external devices or to a BMS.
Premises in non-residential buildings are characterized by highly variable and intermittent occupancy. For example, meeting rooms are generally used for a few hours and their occupancy is quite variable.
Classrooms are completely empty during recreation periods, lunch breaks and vacation periods. The VMX, with its smart ventilation, is well suited for the tertiary sector and allows an optimal management of ventilation flow rates according to the occupancy of the room.
This system yields large energy savings by reducing airflow rates by 25 to 75%, on average, depending on the reference flow rates. Thanks to carbon dioxide or presence detectors placed at different locations in the room, the flow rates are managed strictly according to the needs. This avoids both over-ventilation, which would mean higher energy consumption, and under-ventilation, which could have negative impacts on the health, concentration, and comfort of the occupants.
With its different sensors, the VMX optimises indoor air quality by adapting automatically its ventilation to the needs of the room. If, for example, a room is highly occupied, the indoor air will be charged with CO2, humidity and odours emitted by the occupants which can result not only in discomfort and inconvenience but also in decrease of concentration. The VMX system, thanks to its sensors, will detect the occupancy rate and instantaneously activate the ventilation evacuating vicious air, bad odours and allowing new fresh air in the room.
VMX system offers the possibility to measure three types of information through three detection modes: the “Presence” mode, which adapts the ventilation according to the detected presence. The “Movement” mode, which induces a ventilation rate proportional to the number of movements measured. The “CO2” mode, which adjusts the airflow proportionally or binary (minimum / maximum) to the CO2 rate.
