Numerical Study on a Combined Ventilation System in an Office

Abstract

This paper presents a combined ventilation system and describes its use in an office. Numerical comparative analysis has been done between a combined ventilation system and a fresh air system to assess the performance of the combined ventilation system. Simulations were performed in an office based on the tracer gas decay method. The results show that the combined ventilation system can improve the indoor air quality and reduce energy consumption by comparing with the fresh air system.
