A critical review on the adaptability of ventilation systems: Current problems, solutions and opportunities

O. Seuntjens et al.

Summary: Currently, many buildings are demolished before reaching their technical lifespan due to the inability to meet the changing needs of owners and users. To address this waste, the construction industry is shifting towards adaptable building practices. Comfort systems in buildings play a critical role in ensuring occupant health and comfort in flexible scenarios. However, traditional approaches to ventilation lack adaptability, and there is a lack of specific guidelines for designing adaptable ventilation systems.

A stratum ventilation system for pollutants and an improved prediction model for infection in subway cars

Yanhui Mao et al.

Summary: A study on pollutant concentrations in subway cars of Ningbo Rail Transit Line 2 was conducted, proposing a stratum ventilation technology to improve air quality. Computational fluid dynamics showed that subway cars with stratum ventilation form an air curtain, effectively enhancing air quality within the breathing area of seated passengers. The Wells-Riley model was enhanced to predict airborne infection probability, revealing that stratum ventilation technology reduces the risk of pathogenic infection among seated passengers compared to conventional subway cars.

Using revised ADPIs to identify an optimum positioning for installation of reversible room air-conditioners in bedroom for maximum thermal comfort

Xin Wang et al.

Summary: This study is the first attempt to investigate the optimal positioning for installation of reversible RACs in a representative bedroom. Through CFD simulations and experiments, it was found that slightly higher air diffusion performance indices (ADPIs) can be obtained when the reversible RAC is installed at high level on the longer side of the bedroom.

Experimental investigation on the ventilation performance of diffuse ceiling ventilation in heating conditions

Pei Peng et al.

Summary: The study investigates the performance of diffuse ceiling ventilation (DCV) in heating mode through fullscale chamber experiments. It shows that increased air change rates can improve indoor air quality, while having little impact on ventilation effectiveness. The intensity of internal heat sources and the type of contaminant sources strongly influence DCV's ventilation effectiveness, with the effect of exhaust positions depending on the presence of internal heat sources.

Tracing surface and airborne SARS-CoV-2 RNA inside public buses and subway trains

Teresa Moreno et al.

Summary: A study on public transport in Barcelona during the summer of 2020 found traces of SARS-CoV-2 viral RNA in surface and air samples, with more viral remnants on bus surfaces compared to trains. Although signs of viral RNA were detected, they were considered unlikely to be infectious. Vigilant attention to ventilation systems and regular disinfection of vehicles are necessary to effectively eliminate viral traces, especially during peak COVID-19 periods.
