L'utilisation des nanotechnologies pour augmenter les performances des systèmes de CVC (en anglais)

EnE-HVAC, ou Energy efficient heat exchangers for HVAC applications, est un projet collaboratif financé par l'UE pour réduire de manière significative les consommations d'énergie des futurs systèmes de chauffage, de ventilation et de climatisation via des technologies nouvelles et innovantes.
EnE-HVAC project aims to demonstrate that energy savings of up to 50% on the total energy consumption in an HVAC system are possible with the application of advanced nanotechnologies. The EnE-HVAC project will tackle all aspects of the system, using novel nanotechnological approaches. These technologies include nanotechnological coatings and surface treatments for improved heat transfer, new nano- and micro-materials for improved efficiency of the refrigerants, and improved efficiency and heat transfer capabilities of coolants via new nanotechnological additives.

The technologies used will address the heat exchanger efficiency on both the air- and the liquid side of heat exchangers such as condensors/evaporators and on heat recovery systems. Furthermore, this project will address the heat transport system to ensure high efficiency throughout the HVAC system.

 Also, to ensure the largest possible environmental effects, there will be a significant focus on the use of "green" refrigerants avoiding fluorinated gasses.

The three-year project which runs until 30 September 2015 is said to have achieved a number of significant results. Large-scale test setups for evaluating these nanotechnologies have been designed and are currently being built.
