Abstract. In the article the mathematical model of the processes of heat exchange and mass exchange in the room of building with the natural ventilation is shown. The verification of mathematical model is performed via the comparison of the results of calculation in ANSYS Fluent with the data of experiment. Experiment was conducted in the room of educational institution. In the experiment were measured the temperature of air, air speed and moisture content in air. A low relative error in the calculation with the use of a mathematical model makes its use for predicting the parameters of microclimate after the introduction of the energy-saving measures possible The mathematical model of the processes of heat exchange and mass exchange in the roomThe prediction of the parameters of microclimate in the rooms of habitable, public and office buildings is urgent task. Solution of this problem will make it possible to estimate influence on the microclimate of the rooms of factors, connected with the energy-saving measures [1].For the solution of this problem in Ivanovo State Power University was used the method of mathematical simulation. The thermal, humid and air regime of room was described by such parameters as the temperature of air (Т в , 0 С), air speed (w, m/s), moisture content (d, kg/kg d.a. ) and the concentration of carbon dioxide (СО 2 , ppm). For calculating these parameters the system of differential equations, which contains the equation of the conservation of energy, pulse and quantity of substance, and also the integral-differential equation of the transfer of the radiant energy, was solved [2][3][4].The standard k-ε model of turbulence was used for calculating the turbulent properties of air in the room [5]. The realization of the mathematical model of the processes of heatmass transfer is executed in ANSYS Fluent [6]. The solution of the equations of the transfer in ANSYS Fluent is based on the method of final volumes.

“…-dynamic viscosity mixture, Pa•s: The mathematical model is different, first of all, to use when setting the boundary conditions of actual air space, which is determined experimentally [9]. Secondly research shows [12], the presence of heated or cooled surfaces in the room can have a significant impact on the human feeling of comfort, in accordance with this radiation heat transfer is taken into account by introducing a special source term in the energy equation [4,5].…”

“…In [2] as an additional factor has been proposed level of climate comfort, which includes a coefficient comfort human thermal state (CCH), which was determined by solving the heat of human balance, as well as amendments to the radiative cooling, the asymmetry of the heat flow and air quality medium (the presence of impurities) in the room. Check the adequacy of the developed mathematical model is executed by comparing the CCH values obtained from the experimental results and the implementation of a mathematical model in the environment of ANSYS Fluent.…”

“…In [1,2,3] shows that in the assessment of the effectiveness of energy-saving measures for non-production buildings (residential, public and administrative), an important task is to predict climate parameters that determine the comfort of the premises after the implementation of energy saving measures. Currently, scientists are actively used by a number of software and computer systems, allowing defining the parameters of the environment in the room after making changes to the technical characteristics of the building or changing the operating mode of the power equipment.…”

Microclimate quality required by regulatory documents in the main housing of the thermal power plant is necessary to manage the technological process and comply with labor protection requirements. Thus, obtaining information about microclimate parameters is an urgent task. A passive experiment using state-of-the-industry measuring instruments is carried out to obtain the microclimate parameters in the main housing of the thermal power plant. The main (temperature and relative humidity) and auxiliary (CO2, РМ2.5, tVOC) characteristics of the air environment in the turbine and boiler sections of the main housing of the Ivanovo CHPP-2 are obtained. Analysis of experimental data allows us to draw conclusions that the microclimate parameters at the thermal power plant are in compliance with the current regulatory documents. Information about the state of the microclimate depending on the technological operating mode of the thermal station and the environment will allow us to develop energy-saving measures to reduce energy consumption for in-house needs. It can be useful to check the reliability of the existing and new methods to calculate the microclimate at thermal power plants.
