Heat Engineering Calculation of External Enclosures

When designing external enclosures, their operating conditions are taken into account, determined not only by the load-bearing capacity of the structures, but also by the required resistance to heat transfer, air and steam permeability, as well as heat resistance.

In this course design, the design of fences is conditionally limited only to thermal design. The calculation consists in determining the thickness of the insulation layer of the wall structure, floor (floor) and coating, as well as light openings and external doors in accordance with SNiP 23022003.
