Delficar

The goal of the DELFICAR project is to develop eco-designed filter systems incorporating features that ensure optimal indoor air quality when using air recirculation and CO2 capture ventilation systems.

Today, increasingly stringent regulations are being imposed on emission thresholds for major outdoor air pollutants. While the focus is on outdoor air quality, it is equally important to control indoor air quality, as we spend over 85% of our time in enclosed spaces. Without proper purification, indoor air can become polluted, which may impact occupants' health and even reduce their quality and life expectancy.

In this context, ventilating and purifying the air are essential actions. Ensuring the renewal of high-quality indoor air is already, and will continue to be, a major societal and health challenge.

The DELFICAR project offers a solution by integrating advanced functionalities into ventilation systems, maintaining optimal air quality in recirculated air without compromising the energy efficiency of the ventilation process. A significant part of the project will be dedicated to selecting and characterizing the performance of CO2 fixation materials. The objective is to identify adsorbents that can be regenerated at low temperatures. If necessary, the adsorbent will undergo plasma treatment to introduce amine functions, which are effective in CO2 sequestration and can be regenerated at lower temperatures than pure zeolites. This approach will take advantage of the combination of surface chemistry provided by plasma treatment and the high specific surface area inherent to the adsorbent material.

This function must be integrated into a filtering medium that already possesses biocidal properties. It is crucial to ensure that the various treatments considered for CO2 capture do not compromise the effectiveness of the filter’s biocidal properties.
