dc.description.abstractInvestigation and engineering projects indicate that the underfloor air distribution (UFAD) system is superior to conventional HVAC systems in some aspects. For example, the former is more adaptive in rearranging the office space to improve indoor comfort conditions and energy conservation. However, the supply air outlet of UFAD system is set on the floor, such that the supply airflow may entrain the dust particles settled on the floor or suspended near the floor. This creates problems that need to be studied, because airflow can bring theses particle to the human breathing zone. In this paper, the performance of the airflow field in a UFAD system and the characteristics of supply air entrainment for particles are studied. A physical and numerical model is established. Comparison of the numerical calculation results of the airflow field with the measured data is given. Results show that the model is valid and can predict the performance of airflow entrainment for dust particles in different air supply conditions.en
