Single-flow mechanical ventilation

Mechanical Controlled Ventilation (MCV) with single airflow is currently the most commonly used VMC system in France. It significantly improves air renewal in the home while reducing energy consumption. France Ventilation offers self-regulating single-flow VMC systems and hygro-regulated single-flow VMC systems.

How does a single-flow mechanical ventilation system work?

A single-flow mechanical ventilation system works by extracting stale air from the humid rooms of the dwelling (bathroom, toilet, kitchen) and bringing in fresh air from the outside into the living areas (living room, bedroom, etc.). The air inlets are placed in the living areas, while the air outlets are installed in the humid rooms. Within this category, we differentiate between the self-regulating single-flow ventilation system and the humidity-controlled single-flow ventilation system.

What is self-regulating mechanical ventilation ?

The operation of self-regulating mechanical ventilation (VMC autoréglable) is simple. Its system involves extracting stale air from the humid rooms and expelling it outside through the air outlets. This VMC system operates with a constant airflow rate that is pre-set and does not take into account the humidity level of the room.

What is hygro-regulated mechanical ventilation ?

Hygro-regulated mechanical ventilation (VMC hygroréglable) has the advantage of adjusting the incoming and outgoing airflows according to the needs of the dwelling. A humidity sensor allows the airflow to adapt based on the humidity level in the room. This system provides better air renewal in the living space and is also more energy-efficient. Hygro-regulated ventilation is suitable for both new and renovated homes.

In this category, we distinguish between hygro A VMCs and hygro B VMCs.

Hygro A hygro-regulated mechanical ventilation

Type A VMC (hygroréglable) provides variable air flow based on the humidity level in the room. For this purpose, it is equipped with hygro-regulated air vents. However, when it comes to air inlets, they remain fixed with a constant air flow.

Hygro B hygro-regulated mechanical ventilation

The hygro B VMC also features hygro-regulated extraction vents, which adjust the air flow based on the humidity level in the room. The difference between these two types of VMC lies in the air inlets. In a hygro B VMC, the air inlets are also hygro-regulated. This means that the incoming air flow adapts to the occupants of the house and their needs. As a result, there is better control of humidity levels and improved air renewal. This model also provides enhanced thermal comfort.

How to maintain a single-flow ventilation system ?

A high-performance mechanical ventilation system should be properly maintained to ensure better indoor air quality in the living space. Regular cleaning of the single-flow ventilation system ensures hygiene, health, and efficiency.

A thorough cleaning of your ventilation system should be done once a year to maintain its effectiveness throughout the year. The most suitable period is in spring, after the winter season when the VMC is typically running intensively. However, it is still recommended to have professional maintenance performed every 3 years.
