Development of Calculated Resistances to Heat Transfer of Floors via the Ground Using Modern Methods of Their Thermal Protection
The aim of the article is to develop the calculated parameters of the floors on the ground, consistent with the use of traditional methods of calculating heat loss “by zones” for twomodern designs of thermal protection for different types of soils. The result is achieved by calculating the unsteady annual thermal regime of the soil together with the structures ofthe building lying on the ground. The calculation is performed by the finite difference method. For modeling of long - term two - dimensional temperature field of soil and creation of initialtemperature conditions close to average long - term conditions, at first, the calculation of the annual thermal regime of the soil together with the construction of the building wascarried out according to the climatic data of the average “typical” year, and then the temperature field changing during the year according to the calculated “standard” year was calculated.The article deals with the problem of heat insulation of the underground part of the socle wall and the outer surface of the earth filling under the building at different resistanceof heat insulation to heat transfer, the height of the filling under the floor and the types of soil. The value of the heat loss of the floor via the ground is influenced by all the factorsconsidered: the resistance of heat insulation to heat transfer, the depth of heat insulation of the wall, the height of the earth filling under the building, the type of soil on which thebuilding stands.
