Mechanical ventilation system

Improving indoor air quality, achieving energy savings, and preserving the integrity of the building are all benefits provided by a mechanical ventilation system. Different VMC solutions are available on France Ventilation. They all facilitate the renewal of ambient air, the removal of moisture, dust, and pollutants. It is necessary to have a suitable ventilation system for your home to be as healthy and comfortable as possible. As VMC is a regulatory requirement, it is mandatory in new homes.

What is the purpose of a ventilation system?

Today, buildings are better insulated and nearly airtight. To maintain good indoor air quality, an efficient ventilation system is necessary. Moisture, unpleasant odors, pollutants, and emissions from heating appliances are not fully eliminated on their own. Indoor air can be 20 to 100 times more polluted than outdoor air. Therefore, installing a ventilation system, such as a Mechanical Ventilation System (MV), is mandatory.

A mechanical ventilation system ensures the long-term sustainability of the dwelling and improves the health and well-being of its occupants.

  • Hygro-regulated ventilation systems prioritize the thermal performance of the dwelling by adapting the airflow rates for extraction and intake based on measured relative humidity. This solution is cost-effective, but the trade-off is that it keeps the indoor air close to the dew point (the point at which condensation occurs).
  • Double-flow ventilation systems require a higher investment but clearly prioritize indoor air quality while maintaining high-level thermal performance. They also filter the incoming air, allow for night-time overventilation, and some systems even provide air purification, such as the Inspir Home model from the manufacturer Aldes.

What types of ventilation systems should be chosen?

Single-flow mechanical ventilation

We distinguish between self-regulating single-flow mechanical ventilation (VMC) and humidity-controlled single-flow mechanical ventilation.

Self-regulating VMC ensures constant airflow in sanitary rooms and double airflow in the kitchen.

Humidity-controlled VMC adjusts the airflow based on the humidity level in the dwelling.

There are two types of humidity-controlled mechanical ventilation systems:

  • Humidity-controlled VMC Type A includes humidity-controlled extraction vents and self-regulating air inlets.
  • Humidity-controlled VMC Type B includes humidity-controlled extraction vents and humidity-controlled air inlets. The airflow extraction and supply are adjusted based on the humidity level in each room. This type of VMC ventilates where and when needed. It is commonly used in most newly constructed houses.

On France Ventilation, you can find a wide range of extraction vents and air inlets from brands such as Aldes, Anjos, Unelvent, and Vortice.

Double-flow mechanical ventilation

Double-flow mechanical ventilation provides fresh air to homes while minimizing heat loss associated with air renewal. This system is equipped with a static heat exchanger that can recover heat from the extracted air and transfer it to the incoming fresh air. As a result, in winter, when you heat your home, the incoming air will not have the temperature of the outside air. It will be tempered by the heat from the extracted air. Double-flow mechanical ventilation is currently the best solution for improving indoor air quality in homes.

Insufflation ventilation

Among mechanical controlled ventilation systems, there is also the PIV or Positive Input Ventilation. The principle is the exact opposite of a traditional MVHR (Mechanical Ventilation with Heat Recovery). Its function is to supply fresh air into a dwelling, creating a slight positive pressure. The air is filtered and warmed before being introduced into the living spaces. This system can be used for retrofitting purposes but is not suitable for new houses.

How to maintain and clean your ventilation system?

It is recommended to clean your ventilation system once every quarter.

Here’s how to maintain and clean your ventilation system :

Disassemble the air grilles : You will need to remove all the air grilles and soak them in warm water that has been diluted with a degreaser beforehand. After that, you will need to remove any remaining dust or debris at the entrance of each intake using a vacuum cleaner or a damp cloth.

Caution! If your air grilles are hygroregulable (equipped with a humidity sensor), do not wet them as they could be damaged.

Professional maintenance : You can entrust the maintenance of your ventilation system to a professional every 2 to 3 years. Their intervention includes cleaning, maintaining the ducts and central unit, and checking the air intakes and other components. The cost of this service is approximately €130 for a standard installation and €20 to €25 for an apartment.

Please note that regular maintenance of a gas-powered ventilation system by a professional is mandatory.
