| Abstract |
The conventional UFAD(Under Floor Air Distribution) system has come into wide use as the improved air conditioning system by the performance of energy efficiency. Among the UFAD system, which is increasingly applied to newly constructed buildings, was selected as the analysis target. computational fluid dynamics simulations were performed to predict the airflow and temperature distribution of indoor space. Thermal comfort of the office space by UFAD system in the summer and winter was evaluated by applying the effective draft temperature index, which is the combination of temperature and airflow. Effective draft temperature showed an average of -1.27oC in winter and 1.98oC in summer. It was analyzed that it was possible to maintain stable indoor comfort. |
