Why mechanical ventilation is important

As we know, the air is the most important element for the body's functions: with the progressive trend of climate change, the worsening of air quality and the rapid spread of viruses and bacteria, we are now forced to take measures safeguard for our health and well-being.

The average air requirement of a man is 6/9 liters per minute in rest conditions, destined to rise up to 130 liters per minute in case of intense physical activity.

Most people spend 90% of their day indoors, breathing about twenty thousand times a day: the analysis of these two factors gives us a precise picture of the importance of air quality in any environment, especially in the home .

Indoor pollution and air quality

Breathing polluted air hurts and living in an unhealthy environment can create considerable health problems which can manifest themselves in various ways, such as allergies, headaches, dermatitis which, in the long run, can cause various pathologies of the respiratory system.

Unfortunately, the air inside our homes is often more polluted than the air outside under the worst conditions.

Indoor pollution is responsible for the so-called "sick building syndrome", a pathology recognized by the WHO and which includes various symptoms attributable to the presence of pollutants in residential and working environments.

To the internal pollutants are added all the external pollutants that penetrate through the vertical closures of the building such as smog, fine dust (PM10 - PM 2.5) but also volatile organic compounds produced by vehicles, industries and building materials.

Humidity too, although not a pollutant per se, must be treated as such because if there is excess humidity, it can give rise to the formation of condensation and the proliferation of fungal formations.

How to improve indoor air?

To guarantee the health and well-being of people in everyday environments, it is essential to have good air quality, humidity control and good thermal and acoustic comfort.

It is possible to obtain this result through controlled mechanical ventilation (VMC) with heat recovery.

It is a technology that uses devices with the latest generation of variable speed fans with low electricity consumption and low noise levels capable of guaranteeing:

- introduction of fresh air drawn from the outside and filtered

- external stale air expulsion

- recovery of the energy contained in the air which is expelled through an exchanger. The energy is transferred to the air introduced into the rooms.

In practice, the VMC guarantees the always presence of filtered air by eliminating the polluting substances produced continuously by human activities as well as eliminating bad odors and stale air.

Energy efficiency and controlled mechanical ventilation

The energy efficiency of buildings, essential both in renovations and in new constructions, completely isolates the building from the external environment, no longer allowing the passage of air: for this reason a suitable CMV system must be provided following any intervention for energy improvement of the building.

The autonomous air exchange allows you to keep the building healthy over time, preventing the formation of humidity and maintaining the correct balance in the environment.

Furthermore, a heat recovery unit contributes to energy savings, recovering up to 90% of the thermal energy of the extracted air which is sold at almost zero cost.

Among the various types of systems, the most requested is certainly punctual (or decentralized) mechanical ventilation: in this case, a heat recovery unit is installed in each room which can communicate with each other or work independently.

One of the main advantages of punctual CMV is ease of installation as no invasive masonry work is required but simply a hole towards the outside with a diameter of 100 or 160 mm depending on the model.

It also has a very simple and linear design, which makes the device discreet and easy to integrate into any environment.

The punctual mechanical ventilation heat recovery units are also very silent, making them suitable for bedrooms as well and have low consumption and high efficiency (90% at minimum flow rate).
