Ventilation systems (CMV or AHU) present in a building ensure the renewal of indoor air. These systems guarantee the protection of the premises against damage caused by humidity and mold. They thus keep buildings healthy and protect occupants from the consequences of indoor air pollution. That is why it is crucial to regularly renew indoor air. The proper functioning of ventilation systems is therefore essential.
An efficient ventilation system allows the evacuation of CO2, fumes, dust, mites and limits the development of mold or humidity. The maintenance and controlled management of ventilation systems also reduces energy consumption and improves the thermal comfort of the building.
It has been proven that poor indoor air quality can generate olfactory discomfort, drowsiness or eye and skin irritations, but also more acute or chronic pathologies such as asthma, respiratory allergies, cancer or poisoning that can be fatal.
We then quickly understand the challenges of good air renewal in our homes, offices and enclosed living spaces.
Clean air reduces health risks and also preserves the building. A malfunctioning ventilation system causes significant damage to the building and also considerable repair costs. Risks associated with poor ventilation of the building:
To improve the level of indoor air quality, there are several levers for action:
Regular maintenance of ventilation systems
Early detection of malfunctions in the ventilation system
Daily room ventilation
Indoor temperature and humidity control
Monitoring for the appearance of mould stains
There are currently different types of ventilation systems, each with its own particularities.
In a building composed of dwellings there are generally two types of equipment: either a gas CMV or a conventional CMV.
A gas CMV that breaks down causes the boiler to shutdown immediatly, which results in a cut-off of the hot water supply and potentially of the heating system. The shutdown of this type of ventilation system is very constraining but easily and quickly detectable. In contrast to a failure on a conventional VMC, which is independent of the boiler, for which the external effects of the shutdown or bad system are difficult to perceive. It is often when the first moulds appear that the failure is noticed.
In order to ensure the proper functioning of this equipment, professionals in the sector act on two aspects:
Another solution exists alongside these two types of intervention: the implementation of a monitoring system to intervene before any failures.
Such a solution makes it possible to anticipate the malfunctioning of the VMC/CTA or at least to act as quickly as possible when it occurs. It avoids unnecessary travel by technical teams. Maintenance companies thus gain in efficiency and improve the quality of life of users.
IoT devices such as the adeunis Delta P sensor monitor the ventilation boxes and anticipate possible malfunctions. Thus the professionals of the sector can :
