Due to the increasing number of underground metro stations worldwide and the great
energy consumption of heating, ventilation and air conditioning (HVAC) systems in …

Environmental health in subway stations, a typical type of urban underground space, is
becoming increasingly important. Ventilation is the principal measure for optimizing the …

Due to the rapidly increasing ridership and the relatively enclosed underground space, the
indoor air quality (IAQ) in underground subway stations (USSs) has attracted more public …

Indoor air quality (IAQ) measurements play an important role in the subway ventilation
system control, influencing over crucial factors as ventilation energy consumption and …

This study was based on computational fluid dynamics (CFD) and field measurement
verification. First, we researched and analyzed the main ventilation system, when closed or …

To decrease the high concentration dust in tunnels with a long-duct forced and short-duct
exhaust ventilation system, airflow and dust field migration behaviours, when different …

The understanding of natural ventilation in super-long tunnels can help to optimize the
design of ventilation systems and reduce energy consumption and maintenance costs. This …

In this study, the environmental impacts of six conventional and modern air conditioning
systems, including vapor-compression air conditioning (VAC), hybrid membrane-based air …

The energy consumption of metros has widely been concerned with respect to their
economy and environmental protection. To analyze the complex dynamic relationship …

As subway stations in cold-climate regions typically have no heating systems, passengers
often feel cold in such stations during winter. People desire a comfortable thermal …
