Moisture transport in the ventilated channel with heating by coil

Energy efficiency and thermal protection of buildings

This article considers the moisture transport phenomenon in the vertical ventilated channel. HVF construction parameters are determined influencing the rate of moisture transport. It is necessary to have h ≤ L/25 ≈ 8 cm. The greatest air movement is created in the construction with the open rustications. The optimal location of the heat sources on the channel height, as well as their favorable combination from the point of view for the process of drying the outer surface of the thermal insulation material, was identified. The air velocity dependences on height of an air gap are determined and it was found that the greatest values taken at the maximum height velocity. Ratio between the moisture transport and the distance to the heat source is installed. Drying processes are compared with the various combinations of heat sources. The direct dependence of the vaporation weight rate of the time is installed.
