The experimental study of the indoor climate with the micro-environment systems

Abstract

One of the major challenges in modern buildings is to guarantee healthy indoor air quality and excellent thermal comfort in an energy efficient manner. In this study, the performance of two micro-environment systems combined radiant panel and convective flow was designed. In one of micro-environment system of personalized ventilation and radiant panel (PVRP), two local personal air terminal devices supplied clean air directly to occupants. In the other micro-environment system, low velocity unit was installed just over the radiant panels (LVRP) and the air was supplied through those panels. The radiant panels were used to satisfy the required cooling load. The results show that that it is possible to enhance system performance with micro-environment control systems, where users are able to control their own set points for room air temperature and indoor air quality, the satisfaction on indoor climate conditions increased significantly. Furthermore, the air temperature near the workstation can be maintained at designed value with the micro-environment systems. In particularly, the vertical temperature difference did not cause thermal discomfort with the micro environment systems near the workstation.
