Issues related to indoor air quality

Difficult to perceive, poor indoor air quality is now a real public health problem. Indoor air is 5 to 10 times more polluted than outdoor air. In general, high concentrations of indoor pollution are not detected by label-COV-air-indoor MyADTEC thermodynamic double flow air conditioningresidents. However, they can be the cause of many diseases and respiratory problems, and a general state of “malaise”. Whereas before, we were not very concerned about air pollution in our homes, today our homes are increasingly airtight to limit energy consumption.

Renewing the air in an enclosed space is then a vital necessity today. For that the installation of a VMC is obligatory, it allows to:

  • Renewing the air in the habitat (CO2 extraction)
  • Moisture extraction (Breathing / Showering / Cooking…) Objective: 40 to 60% humidity
  • To extract VOCs (Volatile Organic Compounds) or pollutants released by the materials in the house, in particular formaldehyde.

This is mainly the role of the MyDATEC thermodynamic ventilation system.

When you have a better control of your ventilation rates, it becomes obvious to valorize the heat losses linked to the air extraction. This is why MyDATEC is now used in many schools, day-care centers, dental practices and general practitioners’ offices, where the quality of indoor air must be uncompromising.

Below are a few points that allow you to realize the importance of indoor air quality:

– Every day we eat 2kg of food, drink 2kg of water, and breathe 10kg of air.

– Less than 20% of homes have good air quality

– Air quality has a short and long term impact on health…

– It is considered that 70% of the ventilation systems have too low air flow rates

– The nurseries, since 01/01/2015, must be equipped with a system that measures the air quality

MyDATEC: a unique filtering capacity to limit allergens and pollutants

MyDATEC renews the air: The thermodynamic CMV is the only air heating system that works in all fresh air, which means that indoor pollutants are extracted continuously (unlike a conventional air/air heat pump that works in recycling the indoor air). Since the heat from the exhaust air is recovered by the MyDATEC system, ventilation is no longer a problem. Contrary to other CMV systems that reduce ventilation rates to a maximum to avoid energy losses related to air renewal, MyDATEC thermodynamic CMV extracts as much as necessary for maximum comfort and for a building protected from deterioration related to humidity (mold, fungus, etc.).

Comparison of the minimum ventilation rates required by law, with the rates generated by the MyDATEC thermodynamic ventilation system:(March 1982 order)

Nb of main rooms 1 2 3 4 5 and more
Single-flow humidity-sensitive CMV 10 m3/h 10 m3/h 15 m3/h 20 m3/h 25 m3/h
Self-adjusting single-flow CMV 35 m3/h 60 m3/h 75 m3/h 90 m3/h 105 m3/h
MYDATEC thermodynamic ventilation system From 100 to 300 m3/h From 110 to 300 m3/h From 150 to 300 m3/h From 160 to 300 m3/h From 170 to 300 m3/h

MyDATEC filters pollutants, allergens, etc.: The MyDATEC system performs a double air filtering on the extracted air and on the fresh air before it enters the house. Essential for people who are sensitive to allergies and asthmatics, the system is particularly effective against allergens and conventional pollutants. However, it is very important to clean the filters of your MyDATEC unit regularly. (Filter category from G4 to M5)

How MyDATEC HVAC regulates humidity

The MyDATEC system has a natural tendency to dehumidify. Indeed, the Air quality - VMC double flow thermodynamic house BBC - ventilation heating air conditioningheat pump recovers sensible heat (or heat transmitted by contact) and latent heat (heat released by the changes of state of water), so the air blown in is always drier after passing through the heat pump. This is why the MyDATEC thermodynamic double flow ventilation system is frequently used and appreciated in seaside areas, or to treat particularly humid rooms.

The ideal humidity level is between 45% and 65% relative humidity: below this level, the air is too dry, above this level, the air contains too much humidity (feeling of cold), and above 100%, saturation or fog begins.
