Abstract
Abstract: Open collector and single flue chimneys together with mechanical ventilation systems can pose considerable problems in one space in both technical and legal terms. We attempt to investigate this issue from a technical perspective and we examine specific cases. If collector and single flue chimneys are used together with mechanical ventilation, in certain cases the functioning of the chimney can be hindered and even serious accidents can occur. In this case study, we have elaborated a calculation method which can show the circumstances of the functioning. This calculation method will be presented through some examples. We believe that generalizations can be made based on these examples. This calculation method enables the creation of a software, which can be used by an expert to control the air flow. Thanks to this procedure, one can test the effect of the depression on the collector and single flue chimneys. Firstly, the method will be presented in the case of a flat with 14 pipes , 7 of which are basic pipes . Some calculation examples will be presented for the given flat. In the second part, the air supply of a whole level including three flats with 42 pipes , 22 of which are basic pipes and loops will be analyzed
Keywords: air flow in flats, calculation method, control, basic pipes and loop
