NANOCOOL

Our goal was to develop an innovative HLD system in the range 100-200 kW, where waste heat from the condenser is used for regeneration of the desiccants. The energy demand by this process is 55% of the conventional technique. In cases of severe humid environments, like swimming pools, or kitchens, the energy savings can achieve easily levels of 65%-70%. Several innovative components have been developed, namely:

• Two multifunctional heat exchangers with high corrosion resistance for either water vapour absorption from the air flow or desiccant regeneration;
• Development of a liquid-liquid heat exchanger with high corrosion resistance for desiccant regeneration process pre-heat (liquid-liquid desiccant).

Based on the promising results of the FP7 Thermonano project, thermally conductive polymer nano-composites were considered as material for these components and shaped into innovative engineered heat exchange surface. The partners foresee an initial market worth up to 180 MEuro by 2020, generating/maintaining 4000 job opportunities for skilled operators and installers. The partners expect that the intended HVAC solution will allow cumulative savings on energy bill of at least 60 MEuro with a pay-back time below 2 years in case of 50% use.
