Title of the articleStatistical analysis of an annual course of an overpressure for an assessment of natural air exchange of premises
Abstract.In article the method of a statistical analysis of temperature of external air, speed and the wind direction for justification of parameters of the thermal and wind pressures accepted at calculation and projection of natural ventilation of premises is explained. It is revealed, that for determination of actual size of a thermal head in its annual course, it is necessary to accept monthly averaged values of temperature of a free air, whereas for determination of size of a wind pressure it is necessary to have one reasonable value of calculated speed of a wind. It is shown that the actual annual course of a overpressure decides not only regularities of change of air temperature and wind parameters within a year, but also the characteristic of city building and regularities of interaction of certain buildings on a wind stream (aerodynamic coefficients). The example of calculation of an annual course of an overpressure. Taking into account both forces of natural air exchange, where the share of a wind pressure in the total value of a located pressure is defined, is given. It is shown that actual volumes of affluent air in premises do not meet normative requirements for air exchange even taking into account both forces.
Keywords.Air temperature, wind speed, wind direction, overpressure, natural air exchange.
