| Popis: | The relevance of the study is explained by the fact that in the Russian Federation, the “by zone” method of heat loss calculations of the floor on the ground does not allow considering various factors that affect heat losses. As the heat loss studying method, this work adopts the calculation of the non-stationary annual thermal regime of floors together with the soil mass. There is no such thermal protection indicator as the heat transfer resistance in a non-stationary thermal process, therefore the paper uses a characteristic, in other words, a conditionally reduced one for heat loss calculations through the floor on the ground in stationary thermal conditions. The purpose of this article is to calculate the average characteristic heat transfer resistances for each design zone for thermal protection of the wall area of the floor on the ground with different width of the insulation stripe and heat transfer insulation resistance. The considerable result of the work is detection of significant impact of the soil type, the width of the floor insulation stripe, and the actual resistance to heat transfer of this insulation on the characteristic heat transfer resistance in the first design zone. It follows from the study that the floor thermal insulation stripe in the wall area is the most effective structure of the floor thermal protection, both in terms of reducing heat losses, and in terms of compliance with the temperature standards for the floor. |
