| Abstract |
For the purpose of investigating the effective removal of cooling load from light-weighted building envelope, two air-conditioning systems, conventional all-air and air-barrier system, are evaluated and compared by both experiment and simulation with three different cases during cooling season. The characteristics of window-side building thermal load are assessed by varying supply air velocity in order to seek the optimal system operation condition. The results are as follows. Air-barrier system is more effective to remove solar radiation through glass at perimeter zone than conventional all-air system. The experiment results provide that capturing efficiency to evaluate the effective removal of building load from perimeter zone shows high value when supply air velocity is 1 m/s. |
