Checking and assuring real IAQ and energy performances through demand control and cloud connectivity

Since 2018, Renson has introduced a range of cloud-connected residential ventilation systems, including central and decentral mechanical extract ventilation (MEV), as well as fully mechanical systems with heat recovery (MVHR) (see Fig. 1). These systems incorporate smart control mechanisms that utilize different IAQ sensors (CO2, VOC, RH), to adjust the airflow rate(s) locally or centrally to the detected needs. The IAQ sensors are located at the control valves or at the central unit, but not within the rooms. In that way, the full control system is integrated within the ventilation unit itself. The central MEV system also allows to extract air directly from the bedrooms, in addition to the wet rooms, to improve the sleeping environment...
