Special aspects of calculation of infiltration in residential and public buildings

In the current paper, the methods of calculating infiltration for different ways of the ventilation system operation have been reviewed. The calculation of infiltration losses of buildings in cases of organizing natural and mechanical supply and exhaust ventilation, as well as recent scientific research in this area, has been considered. The calculation of natural ventilation with the values of air exchange given in Set of Rules 54.13330.2016 “Residential multi-apartment buildings” has been compared with the calculation of mechanical ventilation taking into account different glazing of the building facade. The influence of gravitational and wind components of pressure on various facades of the building has been analyzed. The gravitational and wind effects on the building are illustrated as a pressure diagram. The calculation of the specific heat flux for heating the infiltrated outdoor air on each floor is presented. The scientific studies of infiltration losses with a mechanical balanced supply and exhaust ventilation system proposed by A.S. Kubenin in his scientific work have been considered. The method of calculating the amount of infiltrated air for residential and public buildings has been thoroughly researched. Studies of heat consumption for one or more windward facades are presented. Criteria conditions of different schemes of filtration air exchange at different wind directions are formulated.
