Thermal Comfort in an Office Room Using Square Diffuser

The office is an important part of our daily life, people spend most their time doing works inside the and therefore quality indoor environment a significant factor affecting productivity happiness users. Many factors ınfluence pattern airflow: air quality, thermal comfort energy saving in room. In this study, effects square diffusers on investigated numerically for Numerical research was subsequently carried out using validated CFD model. This model solved continuity, conservation momentum equations addition to k–ε equation turbulence modelling. Predicted Percentage Dissatisfied (PPD) frequently used tool assessing human rating. A PPD based control HVAC (Heating, Ventilating Air Conditioning) system has potential provide enhanced location by taking into consideration all main variables. results revealed that conditions occurred according ASHRAE standards room with diffuser.
