ABSTRACT
Paper discuss the problem of theoretical description of indoors temperature maintenance process depending on environmental conditions (sun radiation, temperature regime, wind direction and speed). The article deals with the creation of methods of describing a complex of measures on creation of favorable conditions (temperature regime) for a human being in the room at any time of the heating season. Avoiding complicated models for solving the problem, the dominant factors are taken into account only. In particular, the temperature outside the field only considered as a problem of diffusion a temperature in the space with the wind load characteristics influence on the boundary conditions. The calculation takes into account the heat sources in the form of convectors, which are connected to the automatic heating system. In the description of the thermal variations from the outer surface of the wall to the internal surface of the wall, it is considered as a rod with "isolated" surface that allows you to go to a classical problem of heat transfer through the shank: heat conduction in a shank with a intranscalent surface side. The developed model is used to energy efficiency buildings heating automatic control system design.

Keywords: heat transfer, energy efficiency, heated room, insolation, wind loading, heat-transfer coefficient
