Review paper on CFD simulation technique used to analyze the condition of air and its effect inside an air conditioned room

Abstract :

With the improvement of standard of living, air-conditioning has widely been applied. However, health problems associated with air-conditioning systems and indoor air quality appear more frequently. The present paper deals with CFD study of flow and thermal characteristics in air-conditioned rooms under turbulent mixed convection conditions. Air enters room from a sidewall slot flush with isothermal ceiling and leaves through a slot in opposite wall flush with floor. The numerical simulation of air distribution in indoor space with displacement ventilation using CFD is challenging due to complexity of air diffuser geometry and the complicated air flow pattern. This paper investigates experimental and numerical study of the airflow characteristics for vortex, round and square ceiling diffusers and its effect on the thermal comfort in a ventilated room. The performance of indoor airflow for the office room with the hyid air-conditioning system has been investigated by means of CFD analysis.
