Abstract
Ecological problems are inherent in the issue of air quality in the buildings. The main goal thus becomes the creation of indoor clime, where concentration of the detrimental impurities, such as carbon dioxide, would not exceed established norms. Thus, it is proposed to develop an alternative system of ventilation, which would ensure necessary indoor climate without outside air use. In order to decrease the levels of it inside the buildings, it is suggested to use a winter garden with much greenery, so that the air would be regenerated since the carbon dioxide would be absorbed and oxygen would be evolved. The current work reveals the study results of thermal, air and gas conditions in a winter garden upon the office building. The proposed methodology based on the ANSYS-CFX software, ensures a successful calculation of heating and aerial regimes within buildings that might differ in accordance with various engineering practices.
Highlights
The ecological problems have currently gone top especially in relation with the deterioration in quality of the indoor climate (Kvashnin, Gurin 2008; Germanova, Kernozhitskaya 2014; Lott et al 2017)
In the work conducted a solution for such a crosscutting issue as the regeneration capacity of a winter garden, which is combined with the premises of the administrative building via air in order to decrease the concentration of carbon dioxide and, to increase the oxygen saturation, was offered
The calculated values are used for the modelling of air regime of the winter garden, using the ANSYS-CFX software
Summary
The ecological problems have currently gone top especially in relation with the deterioration in quality of the indoor climate (Kvashnin, Gurin 2008; Germanova, Kernozhitskaya 2014; Lott et al 2017). The main goal becomes the creation of indoor climate, in which the concentration of the detrimental impurities, such as carbon dioxide, would not exceed established norms. Improvements of the air quality at the expense of mechanical ventilation, i.e. the process whereby the air exchange needed between the building and outdoor area is not necessarily effective (Steinemann et al 2017), since there is a possibility of the air pollution coming inside the building. It is proposed to develop an alternative system of ventilation, which would ensure necessary indoor climate without outside air use (Rymarov, Savichev 2013). The most noxious component of the office air is carbon dioxide, which is commonly referred to as an indicator of air pollution (Allen et al 2016)
