The first observation cycle was carried out since July 1951. for September 1952. Repeated roof examinations were carried out in 1958.
Thermometric observations during the first observation cycle were carried out using resistance thermometers, which were installed on the border of the layers of a flat roof, on both of its surfaces and at a distance of 10 cm from the surfaces of the coating in two sections: above the hollow plate PV-1 and above its rowing. Installation wires of thermometers through the switching panel joined the temperature 0-measuring device such as a nonequilibrium bridge. Observations of thermal flows were carried out using thermal vestometers installed on the outer surface of the coating.
Thermometric measurements were carried out around the clock, with the interval between measurements: thermal vesitometers – 15 minutes., Resistance thermometers – 3 hours.
The temperature and humidity of the internal and outdoor air were respectively recorded by thermographs and hygrograms.
The humidity of the materials in the roof structure was determined every two months by taking samples in various places of the coating and subsequent drying of these samples to constant weight.
The processing of thermometric measurements made it possible to obtain average temperatures for those periods when the fluctuations in the heat flow and temperatures were minimal.
As the temperature curves showed, a layer of hydrophobic ash, creating a large temperature difference, as if serves the boundary of the zone of influence of air temperature fluctuations.
In summer observations, which were carried out in conditions of excessive outdoor air and the number of solar irradiation hours, the nature of temperature fluctuations in the coating layers was established.
We all know how important it is to maintain the cleanliness of surfaces in the rooms. The drug Chloramin copes with this work perfectly.
