Special Issue Information

Dear Colleagues,

Replacing used air with fresh air is essential for human health and even life. We spend most of our time indoors, so it is crucial that the environment is healthful. Most buildings are naturally ventilated. It is known that in such a system the incoming air is not cleaned, and thus all external pollutants flow into the rooms with the air. PM2.5 and PM10, harmful to health, often appear in the indoor air, and during the course of indoor activities, the concentration of carbon dioxide can increase above the permissible values. Ventilation efficiency and the ability to clean the air are especially important in the current SARS-Cov2 virus pandemic situation. In addition, the contemporary pursuit of energy efficiency limits air exchange. Insufficient air exchange can cause symptoms of sick building syndrome, which can cause irreversible health effects.

The purpose of this Special Issue is to evaluate the functioning of ventilation systems in all kinds of buildings and to develop good practices in the use of buildings. Original results of field and controlled studies, subjective surveys, models, and review articles on ventilation in indoor environments, as well as the relationship of ventilation with indoor air quality, thermal comfort, and human health, are welcome. We encourage the authors to identify the trends of development of ventilation systems in buildings.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atmosphere is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The ventilation performance of air shafts is important to the air quality of subway tunnels, but there is no unified evaluation index of ventilation performance. In this paper, the air shafts at different locations in subway tunnels were taken as research objects, and the wind speed as well as the particulate matter concentration of each air shaft was tested. The effective ventilation volume and PM2.5 discharge efficiency of the air shafts were defined to evaluate the ventilation performance. It was found that on average, during the subway train service, the station air shaft on the train-arriving side can discharge 2050 m3 of dirty air in the tunnels and inhale 218 m3 of fresh air from the outside environment, while the station air shaft on the train-leaving side can absorb 2430 m3 of fresh air but can hardly effectively discharge dirty air; meanwhile, the middle air shaft can not only effectively exhaust 1519 m3 of dirty air but can also absorb 7572 m3 of fresh air. In addition, the middle air shaft has better ventilation performance if its inner opening is set on the top rather than on the side of the tunnel. The PM2.5 discharge efficiency of the station air shaft on the train-arriving side is 52.0~62.8%, higher than that of the middle air shaft of which the value is 26.8~40.7%. This research can provide guidance for ventilation performance evaluation of subway air shafts and provide a reference for subway tunnel air shaft location design. Full article
