Project for the application of nanotechnology in HVAC systems

Spain. The Technological Institute of Construction has been working on a project called "Nano-HVAC", with which they seek to apply nanotechnology in the improvement of HVAC systems by developing an innovative solution for the insulation of pipes of these systems, also introducing new cleaning and maintenance technologies.

The objective of the project is to be executed by means of highly insulated and safe HVAC pipes that minimize cold/heat losses: by means of cost-effective, safe and extremely insulating insulating material that can be applied in circular ducts (injectable material) and square pipes (prefabricated panels). 

The insulating material consists of insulating foams based on foamed polymerized silicates and aeroclays, injectable in fresh and that can be applied during the production process of the conduction tubes in an automated way, avoiding manual operations currently required by conventional insulating materials. The ultimate goal is that these foams, together with advanced maintenance systems, guarantee savings in energy losses of 50% compared to conventional systems.

Through anti-pathogenic and anti-allergenic components of affordable cost that act during the operation and maintenance operations of HVAC systems and reduce the growth of microbes and microorganisms in the pipelines. This will be achieved through the application of two products developed throughout the project:

- Publicidad -

- An anti-microbial, photocatalytic coating, applicable by spray in the filters of the HVAC system, based on titanium oxide nanoparticles.

- A polymeric liquid based on epoxy resin, injectable into the air ducts during maintenance work, with content of anti-microbial silver oxide nanoparticles. This liquid will polymerize in situ, creating a coating <20μm that will coat the surface trapping dirt and microorganisms, and regenerating the duct. This process will be carried out from time to time, without affecting the energy consumption of the HVAC system.

The collaboration project, involving 11 European entities, including AIDICO, will end in August. More information click here.
