【 摘 要 】

Advantages and disadvantages of modern frame-tent constructions are considered in the article. Established there are some market offerings of heated buildings with a layer of thermal insulation, and without it. Now, there is no applied engineering calculation technique to define the heat losses from frame-tent constructions. Existing approaches don't allows to produce the correct results. It leads to exceeding or deficit of thermal energy supply in the building. In this work the real frame-tent building without a thermal insulation in Yekaterinburg equipped with an air heating system is considered. In the course of natural surveys, real transmission losses were defined from the heat and air balance. This value is exceeding the real capacity of the heating system in the building. It is also established, that the obtained coefficient of heat transfer of frame-tent structures is higher that normative values of thermal protection.
