How to establish the connection of an VMC?

Nowadays, air pollution is not only due to the unloading jars of cars that are increasingly numerous, but also factories that contaminate the air with the smoke they send to the atmosphere.

The existence of volatile organic compounds or Covs from the evaporation of solvents, without forgetting sources, such as decoration materials, paintings, paints, hill and all these little things used in daily life, all constant the air.

Everyone knows well that a polluted internal air can cause serious inconveniences and even diseases, such as the irritation of the respiratory tract, allergies, also asthma for the most serious cases.

Currently it is shown that the air inside the houses is five to six times more polluted than the external air. Since modern man spends on average 16 hours a day in a closed space, internal air pollution can cause serious problems.

For the well -being and health of the population, the ventilation of closed spaces, residential houses or offices, is a necessity and not an optional luxury. The government took the question very seriously to the point of deciding with the decree of 24 March 1982 that the general and permanent ventilation of housing is mandatory.

Several means can be adopted to ventilate the interior of houses and offices. But almost always, these are not enough to obtain uninterrupted ventilation.

A well -ventilated interior is a closed place where the stale air is expelled outwards by extraction mouths. This air is replaced by pure air from the outside. For several comforts, Its renewal must be carried out automatically and continues.

What is the VMC?

It is a significant abbreviation «Controlled mechanical ventilation». VMC is a device that allows the renewal of permanent air in an office or accommodation. To ensure ventilation and renewal of the air inside a wet room or marked by smells, it is integrated into the building.

The installation of a ventilation system is essential for old accommodations as for new houses. This installation puts an end to humidity and smell problems, allowing residents to benefit from healthy air.

On the market there are two large VMC families. Simple flow vmc and double -flow VMC.

• The simple VMC flow is characterized by the fact that it sucks the air of a house and refuses it outside by the pumps of the roof. The single flow VMC has two versions:
  • The adjustable car VMC -which constitutes the basic model. Whatever the weather conditions or the lifestyle of the occupants of the house, the air flow is always constant.
  • VMC Igororegabile: for this version, it is the measured humidity level that modulates the air flow extracted in each room.
• The double -flow VMC: the double flow system limits the heat loss linked to ventilation. The air filtered from the outside is heated by the calories of the expulsion spoiled air. Unlike the simple VMC of the flow that has only one network of ducts, the double flow system has two. The VMC is characterized by the absence of air input in the main parts.

Whether it's simple or double flow, A VMC is designed to ensure the renewal of the internal air permanently. To optimize the device by saving energy and avoid heat loss in winter, The installation must respect some rules:

• The extraction box must be positioned in the center compared to the various ventilation mouths;
• To limit the noise produced by the VMC, the boxes must be suspended from the frame using the strings or arranged on a carpet of anti-vibration foam on the ground;
• Before performing the perforation of the insertion holes of the VMC mouths, using a metal detector, proceed with the position of the position of the metal fur of the ceilings.
• The increases in the efficiency of the system on condition that doors and windows are closed. A space of air circulation about 1.5 cm high in the lower part of the doors is necessary for optimal operation of the device;
• For large parts, opt for the installation of different air flows air flows with reduced air flow instead of a mouth with a large air flow.

The implementation of a single VMC flow

For those who have a small FAI -Da -te experience, the installation of an VMC is a relatively easy operation. However, being adequately equipped is essential.

For better installation, the air suction mouths must be placed in «dry» rooms so called, such as the living room, the living room and the bedrooms. As for the air extraction mouths, they will be placed in the water rooms, such as kitchen, bathroom and bathroom. The sheaths will connect them to an extractor. This will guarantee the evacuation of the stale air outside, as well as the circulation of healthy air in the different rooms of the house.

THEThe following installation accessories will be used to install a single flow VMC:

For each wet room, you need an extraction group, extraction mouths, cuffs and sheath. The tightening necklaces or insulating sticker will be used to connect the ducts. If the trip is made outside the heated volume of the building, it is necessary to provide for the isolated sheath.

To install a single flow VMC in the rules of art, it is necessary to follow the following steps.

Step 1: To prevent the extraction box from resonating directly on the ceiling, it is highly recommended to repair it in height. It can be attached to the frame with a rope and python.

Step 2: To determine the exact position of the extraction mouths, identify with a metal detector, metal fur in the ceiling;

Step 3: Place the different extraction mouths. To do this, pierce a hole in the ceiling using a saw;

Step 4: Once the extraction mouths are in place, attacked to the ducts;

Step 5: Using a flexible PVC duct, tie the bracelet to the extraction box. To correctly block the end, use a tight necklace;

Step 6: This penultimate step is to create the exit from the roof. To perform this operation, use a socket tile to cut isolation and any screen. When the duct is in place, connect it to the box with a tightening conduit;

Step 7: Equipped with a break, installing the various air inputs in the upper part of the windows.

Your simple VMC flow is installed. All you have to do is test it.

• The test after installation

When you have finished installing your simple flow VMC, you can test your group. Begins by restoring the group feeding. Normally, as soon as the current is restored, the group begins.

• Install a double flow VMC

The installation of a double -flow VMC is a complex and expensive operation. The price for a double flow of the equipment and the cost of the installation will be between € 2,500 and € 5,000. We highly recommend calling a professional.
