What It Is and Why It Is Essential for the Well-being of Your Home
Controlled Mechanical Ventilation (CMV) is an advanced technology used to ensure air exchange in residential and commercial environments. In recent years, VMC has become a key element in improving living comfort, energy efficiency and indoor air quality. In this article, we will explore what VMC is, how it works, and why it is essential for the well-being of your home.
What is Controlled Mechanical Ventilation (CMV)?
VMC is a ventilation system that, unlike traditional natural ventilation systems, is designed to manage the air flow in a building in a controlled manner. This system mainly consists of a mechanical ventilation unit that sucks in stale (humid and polluted) air and replaces it with fresh air from outside, maintaining a healthy and comfortable environment.
Types of VMC: Heat Recovery VMC and Simple VMC
Heat Recovery VMC (Dual Flow VMC): This system not only manages the air exchange, but also uses the heat of the exhaust air to pre-heat the incoming fresh air. Thanks to a heat exchanger, the outgoing air gives up heat to the incoming air, reducing heat loss and improving the energy efficiency of the house. This type of VMC is ideal for houses with good insulation and for those who wish to minimise energy consumption.
Simple VMC: Simple VMC is a more basic system in which stale air is extracted and replaced with fresh air without heat recovery. This type of VMC is cheaper, but does not offer the same benefits in terms of energy efficiency.
How does the VMC work?
The VMC works via a network of ducts, fans and a central unit that regulates the air flow. Fresh air enters the rooms through a series of inlet vents, while stale air is expelled through extraction vents. The ventilation unit is able to control the amount of inlet and exhaust air, maintaining a constant and balanced air exchange.
In the case of Heat Recovery VMC, a heat exchange device allows heat to be transferred from the outgoing air to the incoming air, ensuring that fresh air is already tempered before entering the room.
Why Install a VMC in Your House?
Air Quality Improvement
One of the main reasons why it is recommended to install a VMC is its ability to improve indoor air quality. The VMC removes excess humidity, odours, polluting gases (such as CO2) and fine dust, promoting a healthy, allergen-free environment.
Moisture Control and Mould Prevention
Mechanical ventilation is particularly useful for preventing the formation of mould and condensation in homes. By eliminating excess moisture, VMC reduces the risk of damaging walls, ceilings and floors with fungal and bacterial growth.
Energy Efficiency
Heat Recovery VMC is an ideal solution for saving energy. Thanks to heat recovery, incoming air is pre-heated, reducing the need for additional heating and lowering energy costs. VMC is particularly advantageous in well-insulated houses, where temperature management is crucial.
Living comfort
Proper ventilation ensures a constant temperature and controlled humidity, making the indoor environment more comfortable all year round. In addition, VMC reduces outside noise, promoting better sleep and a higher quality of life.
Ease of Maintenance
VMC systems require minimal maintenance, mainly filter replacement and duct cleaning. Due to their efficiency and durability, they are an ideal choice for those seeking long-term solutions.
When Is It Indispensable to Install a VMC?
VMC is particularly recommended in well-insulated houses with airtight windows and doors, where natural air exchange is limited. It is also essential in damp rooms such as bathrooms, kitchens and basements, where excess humidity can lead to mould and other problems. Homes in particularly polluted areas or with poor outdoor air quality can benefit greatly from the installation of a VMC.
Investing in a Controlled Mechanical Ventilation system is an advantageous choice to improve the air quality, living comfort and energy efficiency of your home. If you want to ensure a healthy, humidity- and allergen-free environment, VMC is the ideal solution for you.
