A poor indoor climate in buildings can lead to a diverse range of complaints among users. For instance, eye, nose and throat irritation, headache, fatigue, odour nuisance and increased sensitivity to certain substances.
Over the last 20 years the government building regulations have been dramatically tightened in the area of indoor climate. For new build projects, this has resulted in strict standards relating to insulation. Particularly due to this improved insulation, the natural ventilation of buildings is often no longer sufficient to supply adequate fresh air in living areas within buildings. Mechanical ventilation has become essential.
For more than 25 years, Ned Air has been delivering suitable ventilation systems and air treatment equipment for the construction sector, with and without heat recovery.
Air treatment with mechanical ventilation
In air treatment systems with mechanical ventilation, the air flow can be controlled via a supply or extraction fan with adjustable speed, where the speed is adjusted via a sensor. The most common sensors are those which measure the CO2 concentration or the relative humidity (RH), compare the levels with a set value and then ventilate the room accordingly.
Balanced ventilation with heat recovery
With ventilation, the extracted air is often warmer than the supply air, which leads to heat loss. If the extracted and supply air cross, a heat exchanger can be placed between the two air streams. The heat of the extracted air is then transferred to the inflowing, colder air. These heat exchangers achieve an efficiency above 90%,which limits heat loss.
A ventilation system with balanced ventilation is based on the creation of a balance between extraction and supply of air in the building. The stale and moist air is extracted from the building. The same amount of clean air is heated via a heat exchanger and blown into the building. The same amount of air goes in as goes out. The fresh outside air is also filtered.
Comfortable indoor climate
The climate of a room, and the degree to which users judge it to be comfortable, is particularly influenced by two factors: Firstly, the temperature, and secondly, the freshness of the air. The temperature factor concerns the temperature of the room, but things like draughts or incoming sunlight can also play a role. With air freshness, unpleasant odours are often a factor, as well as the concentration of CO2 in the air. The greater the CO2 level, the lesser the air quality.
A Ned Air ventilation system makes the indoor climate easier to control and can reduce health-related complaints among users of the building. Contact one of our advisors with no obligation, to discuss your personal indoor climate solution.
