Deflector role in formation of apartment air exchange of the multistorey building

Abstract

The purpose of this article is to identify capability of deflectors to raise air consumption over an expense, formed in system with a hood, and assessment of efficiency of this unit for application in the nineteen-floor residential building in the conditions of Moscow. This research is performed with the help of a calculation method on the electronic computer in the Matlab programming language. In the research we perform multiple calculations of the air mode of the residential building. The object of the research is a section of the nineteen-floor residential building. In the building the natural system of supply and exhaust ventilation is designed, which comes to an end, in the first case, with a hood, in the second –with the deflector TsAGI. Calculations were carried out in parameters of external air of winds of various directions in January. The results of calculations show whether installation of the deflector in the system of natural ventilation exceeds an air consumption over an expense, formed in system with a hood. On the basis of the received results recommendations about improvement of air exchange of apartments of the multistorey building are made.
