ventilation

Ventilation strategies for multiunit residential buildings are described according to the results of a survey in 260 randomly selected buildings in Canada. Most buildings use corridor pressurization systems with an either central or apartment-based air exhaust. Some outdoor air is delivered to individual apartments, but in some cases, corridor air systems act as a ventilation system for individual apartments. Occupants complaints have been recorded, the main one being odor transfer between apartments.

Measurements and CFD simulations are compared for 4 different ventilation systems using the air change index and a new ventilation parameter. It is shown the advantage of impinging jets

This paper presents a numerical method aiming at recreating the concentration field of a pollutant at each point of a ventilated enclosure that contains one or several pollutant sources of unknown emission rate.

Flow, temperature field and contaminant concentration distributions are analyzed using CFD for 5 different ventilation systems.

This paper deals with a 3D numerical study to assess the effectiveness of a displacement ventilation system to remove particulate pollutants, generated in the occupied zone of a room.

In this study, an office with mixing ventilation is considered. The CFD analyses show that for high cooling loads it is useful to couple a cold ceiling to primary air system

This paper deals with the integration of CFD analysis tool with genetic algorithms. This integrated process presents advantages in generating design alternatives that tally with multiple design, thermal and ventilation criteria.

This paper deals with a CFD simulation of a chilled ceiling in a test chamber. The results demonstrate that a slight non-uniformity in cooling power of the ceiling panels produces a great asymmetry in predicted room airflows.

The aim of this work was to develop a new calculation method of the zonal air velocity in ventilated room during the design stage. The verification showed a good correlation between the method and the experimental data.

In this paper the application of CFD simulation with unstructured fine elements system was carried out to obtain airflow data for the boundary conditions for an air flow.Tthe results were compared with the measured data.
