| Title of the article | Qualitative characteristics of air exchange of premises and their dependence on space-planning and constructive solutions of buildings |
| Abstract. | The air environment of modern residential buildings is subject to a huge number of polluting influences. As a result of it internal air of premises is at 4-5 times more polluted, than atmospheric, the number of the people suffering from a syndrome of the sick building grows. For providing sanitary and hygienic requirements in apartments natural ventilation without the organized inflow is provided. Existing standard approach to design of natural ventilation is reduced to determination of sufficiency of size of an excess pressure for removal of settlement amount of air only at a certain temperature of external air +5 ?С without wind action. Other processes of natural air exchange in apartments in other season remain not captured. In the real work the indicators defining quality of air exchange are revealed: - frequency rate of air exchange; - speed of air streams in a served zone of rooms of the apartment; - duration of change of air in rooms; - overflowing of air streams from «dirty» rooms in living rooms. By means of modeling CFD on the example of four types of three-room apartments of mass series quantitative indices of qualitative characteristics of air exchange of premises are investigated. Dependences of these indicators on space-planning and constructive solutions of apartments are established. |
