Recently, development of system that improve thermal comfort environments in perimeter zone is increasing. Nevertheless, it is actuality that there is no optimum design guidelines for the system. For improvement of this problem, the purpose of this study is to provide optimum control guidelines on the air-barrier system(ABS). Firstly, we analyzed heat flux model through window and examined sol-air temperature about azimuth different. Secondly, we analyzed dynamic operation characteristic of the system using the yearly outdoor air temperature in Korea. The results indicate that velocity control is important to converse energy and to maintain thermal comfort environment on air-barrier system.

Recently, development of system that improve thermal comfort environments in perimeter zone is increasing. Nevertheless, it is actuality that there is no optimum design guidelines for the system. For improvement of this problem, the purpose of this study is to provide optimum design guidelines on the air-barrier system(ABS). Firstly, we measured air velocity and indoor temperature distribution through experimental tests. Secondly, by using the three-dimensional numerical simulation software based on computational fluid dynamics, we produced similar results for both simulation and experimental tests. The results indicate that velocity control is important to converse energy and to maintain thermal comfort environment on air-barrier system. Also, in case of operating by equal flow rate, it is easy to create air barrier in cooling mode than heating mode.
