Abstract
Laboratory and full-scale experiments were carried out with new facade systems with ventilated channels to remove excess moisture from the insulation material. The aim of the work was to study the effect of ventilated channels of facade panels on the moisture condition of the heat-insulation. In laboratory experiments, the effect of air velocity in ventilated channels on the heat-insulation moisture content at different indoor air humidity was investigated. The results of measurements of temperature and relative humidity of air in the panel and in the ventilated air channels at different humidity of the indoor air in the cold period of the year are given. It was found that even with a high humidity of the indoor air of about 70%, the relative humidity of the air in the material of insulation did not exceed 50%, which provided high heat-protected properties of the panels. Temperature stratification of 8–10 °С on height was recorded in the ventilated channels. It led to the appearance of free convective upward currents in the channels and intensification of the moisture removal from the insulation.
