D-40 Indoor Air Quality and Thermal Environment in Room with Task Ambient Air Conditioning System with Natural Ventilatin : Part 3: Airflow Modeling of Under-floor Air Supply Opening for CFD Simulation

Abstract

Task ambient air conditioning system with natural ventilation can be switched ambient air conditioning from mechanical air conditioning to natural ventilation. In this study, airflow of task air conditioning by under-floor air supply opening is modeled for CFD simulation that velocity values near supply opening are fixed using measured data. Airflow modeling method of this paper is improved on the previous paper. And the results of CFD simulation are compared with the measured temperatures in the experimental room.
