Abstract

The purpose of this numerical study is to evaluate the thermal comfort and indoor air quality provided by a surface confluent jets ventilation system applied on a virtual occupied chamber. This numerical study is carried out using a coupling of an integral numerical model, that simulates human thermal response systems, and differential numerical model, that simulates the computer fluid dynamics. The Draught Risk around the occupants, thermal comfort, indoor air quality and Air Distribution Index (ADI) are evaluated. The study was performed for winter and summer typical conditions. The results show that the surface confluent jet system presents, in general, an acceptable thermal comfort level and an acceptable indoor air quality, with carbon dioxide concentration values below the limit of 1800 mg/m3. The ADI value is better in winter than in summer conditions
