Provides a list of the basic equations that are included in the mathematical model, the type of algebraic turbulence model. Describes conducted to determine the coefficient of turbulence χ laboratory and numerical experiments. The experimental results are plotted (Figure 2). Coefficient χ is selected corresponding to the results of laboratory experiments. Describes the full-scale and computational experiments performed to assess the adequacy of the proposed mathematical model in the software package «Locairheat». In the field experiment investigated parameters plenum heated air stream from the gas air-heating unit of the brand «Monzun» company «Mandik» with the possibility of full or partial recycling and forward flow. Computational experiment is modeled on the original parameters of natural experiment. Present the results, an evaluation of the results of the statistical Fisher’s exact test. The conclusion about the adequacy of the mathematical model.
