The article presents the results of studies to determine the energy efficiency of the two options for the mutual placement of the fan and the air heater in the ventilation system. The traditional variant with the installation of the air heater to the fan and the layout solution with the installation of the air heater after the fan are considered. It is shown that thermodynamic processes occur in the systems under consideration, the direction and energy efficiency of which depends on the layout solution of the system. By using the method of analysis of aerodynamic efficiency of ventilation systems, it is proved that the implementation of the objective function of the system with the highest energy efficiency corresponds to the installation of the fan in front of the air heater. This option corresponds to the minimum values of the volumetric capacity of the fan and its power consumption.

In the paper, on the basis of the equation of motion of an incompressible lubricant having the micro-polar properties for the case of a ""thin layer"", the equation of continuity, Darcy and the formula for the energy dissipation rate for determining the function Ф (θ), caused by the molten surface of the bearing bush covered with a low-melting metallic melt of a carrier asymptotic solution by the thermal parameter K. Using a self-similar solution for the zeroth approximation, i.e. without taking into account the melt of the low-melting metallic melt, and for the first approximation, taking into account the low-melting metallic melt, the velocity and pressure fields in the lubricating and porous layers are determined, and the basic performance characteristics of the radial slide bearing are determined. The characteristic permeability of the porous layer and the melt of the surface of the bearing bush, coated with a low-melting metallic melt, on the load capacity and frictional force are estimated.

The article reveals the relationship between the concepts of "ecology", "Anthropoecology"and " architecture". The analysis of the concepts of "architecture" and "Anthropoecology", common to them, their identity, is that the object of consideration is the external environment in relation to man. It is established that the objective of Anthropoecology, in this context, is the study of human interaction with the environment, determining the conditions of its comfort and utilitarianism for humans, and the subject of architecture – the formation of the environment through the construction of buildings. The direct connection and continuity of ecology and architecture in the formation of an artificial human environment determines environmental friendliness as an essential, profound property and the mission of architecture. On the basis of comparative analysis of the concepts "Anthropoecology" and "architecture" their deep essential interrelation is established, which determines the necessity of anthropoecological approach to architectural design, as well as the transition to the integrated assessment of environmental characteristics of real estate objects.
