  1. Nanotechnologies for HVAC systems EeB.NMP.2012-4 Nanotechnology based approaches to increase the performance of HVAC systems

  2. S/T goals of the supported area • Different technological solutions based on nanotechnology in order to: • Contribute to a reduction of the overall energy demand via nanotechnological solution • Improve HVAC systems or building components performance both for the cooling and heating mode • Reduce the global warming effect of HVAC systems

  3. Expected impact of the supported area • Demonstration at industrial system level • Increased quality of the indoor environment • Optimised heat exchangers for energy efficiency are expected to reduce energy consumption by 50% relative to similar conventional systems • Shift to non-fluorocarbon refrigerants in order to reduce impact on global warming

  4. Achieved/expected impact • Hybrid Liquid Desiccant cooling system (NANOCOOL) • Latent load removed by a liquid desiccant dehumidifier (LiCl-water) • Sensible load removed by a conventional vapor compression air cooler • Cleaning of air • Falling film absorber and regenerator: use of nanocoatings for improvement of wettability • Liquid-liquid heat exchanger: use of thermally conductive polymer nano-composites • Development of non-fluorocarbon refrigerants based on nanotechnology. Trials on Nanodiamond doped natural refrigerant are being conducted • Demonstration of reduced total service life costs for owners and occupants is expected in the next phases of the project. Improved wettability Nanocool system

  5. Achieved/expected impact • Improved air quality (bacteria, allergens) and increasing insulation (NanoHVAC) while maintaining a cost-effective solution: • Improved filters • Efficient and cost-effective cleaning systems integrated in an automatic system • Improved insulation with increased fire resistance • Integration of the developments in the automatic manufacturing process • Increasedheat transfer efficiencies by the use of (EnE-HVAC) • Nanostructured surfaces have been developed at lab-scale and full-size heat exchangers produced for test • Nanofluidshave been developed for use as brines. Tests on large-scale systems expected to start very soon • Nanotechnologicalcoatings for anti ice formation is under development with promising results

  6. EnE-HVAC: Achieved/expected impact Activities for dissemination/exploitation • Dissemination with a focus on the “green angle” of the technology development including feasibility and costs effectiveness • Good industrialnetwork ensuring dissemination of project results to a wider industrial audience. This includes publication in trade journals, company magazines, etc • Scientific dissemination through workshops, scientific publications and conferences
