This month sees the launch of a new heat recovery unit, the HR250 Neti which is the second in the last 8 weeks from European market leader Vortice. The company has been selling MVHRs for many years, but promised further new product development this year for this sector.
General Manager Kevin Hippey said:
“As far as architects, specifiers and developers are concerned, our research suggests that there are four key areas which are of greatest importance to them, high thermal efficiency, low noise emissions, low specific fan power and ease of installation.”
These features were all built into the design of both new MVHR units launched by Vortice this year as well as the key consideration of product impact on indoor air quality. For decades, the indoor air that we breathe has been taken for granted however with new builds becoming more airtight reducing indoor air pollutants is becoming more important.
Kevin Hippey continues:
“Europeans spend at least 90 per cent of their time indoors, so their exposure to air pollutants largely depends on their indoor exposure. These pollutants include volatile organic chemicals (VOCs), gases such as nitrogen dioxide, ozone and carbon monoxide, particulate matter and fibres, and biological particles such as bacteria, fungi and pollen. The Clean Air Act of 1956 largely dealt with severe exterior air quality issues but attention now needs to focus on the air that we breathe inside our homes.”
Pollutant sources include outdoor contaminants from traffic and industry, which enter buildings by infiltration and through ventilation systems. Indoor contaminants include burning fuels, candles, tobacco, cleaning products, electronic equipment, toiletries and pets. The pollutants impact on health depend on their toxicity, concentration and exposure period and range from odour to irritation to serious toxic effects. The 2006 revision of the Building Regulations concerning ventilation (ADF) set performance criteria for several air pollutants, including VOCs, nitrogen dioxide and carbon monoxide.
Both new Vortice MVHR units include filtration on the supply side of the MVHR system to try to prevent as many external pollutants as possible from entering the home. Properties in inner cities are particularly vulnerable to these, with high volumes of traffic or industry close by. Vortice offers a range of filter options with both MVHR units in order to remove small particulates.
