NanoHVAC Training Workshop - Greece
The NANO-HVAC project concept aims at developing an innovative approach for ducts insulation while
introducing new cleaning and maintenance technologies, all enabled by cost-effective application of
The main concepts are:
Safe, high insulating HVAC-ducts enabling minimization of heat/cool losses: cost-effective, safe and extremely
thin insulating duct layers that can be applied both to circular ducts (wet-spray solutions) and to square ducts
(pre-cast panel). Insulation will be obtained using sprayable aeroclay-based insulating foams that can be
automatically applied during manufacturing of ducts, avoiding manual operation needed for conventional
materials. Such technologies, coupled with advanced maintenance systems (objective 2) will guarantee a 50%
saving in energy losses compared with conventional ducts.
Cost-effective pathogen and allergenic removal during operation and maintenance to reduce microbial
growth: (a) development of anti-microbial, sprayable and self-adhesive photocatalytic coating, based on titanium
oxide nanoparticles, for HVAC filters. (b) Development of an injectable liquid polymer matrix
containing antimicrobial nanoparticles for air ducts in situ maintenance activities. The liquid polymer will polymerize in situ creating a thin coating
which will cover the surface trapping dirt, debris and microorganisms, thus "regenerating" the duct inner layer. The procedure may be repeated over time without affecting HVAC energy performance.
Scientific and technological objectives within NANO-HVAC project can be organised in four areas: (1) high
efficient and cost-effective insulation solutions for HVAC ducts (2) inhibition and removal of pathogens and
allergenics (3) integration and lab scale characterization, (4) demonstration and validation.
The project duration is estimated to be 36 months, with tasks organized in 9 Work Packages.
