ethod of determination of wall maximum humification localization for analysis of protection against compound building wall excessive moistening // 2628530
FIELD: measuring equipment.SUBSTANCE: one measures the wall temperature, where the wall outside surface temperature is measured in the capacity of the wall temperature, the interior wall temperature and the temperature among the material layers that form the wall. One also measures the integral outside air temperature for the period with the negative average monthly temperature and the indoor temperature. After that, one draws the polygonal line of the temperature variation across the wall thickness. Afterwards, one compares the temperature value on the boundaries in each of the wall layers with the temperature in maximum humification localization for every wall material layer by virtue of the construction of a temperature curve diagram across the material layer thickness and the temperature graph in maximum humification localization across the material layer thickness. This graph is a horizontal line of a constant temperature across the wall thickness. And if the line of the temperature in maximum humification localization intercrosses the temperature variation across the wall thickness line, then one verifies that the maximum humification localization of the wall material layer passes against the wall through the crossing point of the above-mentioned lines. If there is no maximum humification localization in two neighbouring layers and, at the same time, the maximum humification line in wall material outer layer lies higher than temperature variation line in this layer, the line of the temperature in maximum humification localization in the inner layer lies below the temperature variation line in the inner layer, then one verifies that the wall maximum humification localization centres around the joint of the two layers of this wall. And if the maximum humification localization is not determined in accordance with the two above-stated versions, then one verifies that it is placed along the outer surface of the wall outer layer.EFFECT: simplification of the analysis of protection against excessive moistening.4 dwg
