Webinar – Preliminary results of a 15 years follow-up monitoring study
How do humidity sensitive products perform over long periods of time?
With 35 years of existence and more than 10 million equipped dwellings, mechanical humidity-based demand-controlled ventilation (RH-DCV) can provide a comprehensive feedback on both installation, aging, and maintenance of its components, and performance of its systems. Their working principle is based on the extensions and retractations of a hygroscopic fabric, which pulls on a shutter to modify the device’s cross-section – hence the airflow – upon humidity changes in their environment.
A large-scale monitoring on thirty new occupied apartments in two residential buildings, equipped with (RH-MEV), was held from 2007 to 2009. The equipment included indoor air quality (IAQ) sensors in different rooms of each dwelling, as well as pressure and volume flow sensors for monitoring the ventilation system.
Ten years later the acquisition system was turned back on with the intention to assess the ventilation components and system behaviour/performance after a prolonged in-situ functioning period.
Discover in this webinar the main results of the 2007-2009 study together with the preliminary results of the study held in 2017 and 2019-2020, and the perspectives for 2021-2022, here and on our youtube channel.
Duration : 20 min speech – 15 min questions.
