M. Ruiz de Adana: High Indoor Air Quality (IAQ) has been always a requirement in indoor spaces in buildings. Since COVID-19 started, IAQ is even more important and outdoor air intake is an important requirement to lower the probability of airborne infection. So, the more outdoor air supplied by the HVAC system, the lower is the risk of airborne infection. RACU ensures 100% of outdoor fresh and filtered air supply into the building, thus lowering the risk of airborne infection without any major increase in energy consumption.
For example, in hospitals, the ventilation requirements are very high. RACU could fulfill these requirements by using 100% renewable sources. The higher the ventilation requirements, the higher the potential of RACU for that building, since, to date, RACU is one of the few technologies that has the potential to allow 100% outdoor air renewal.
