Variable refrigerant flow (VRF) systems are known for their high energy performance and the installation of VRF systems in buildings is increasing. However, most studies have focused on improving the mechanical efficiency of VRF systems and there has been little research on energy efficient control strategies considering the thermal comfort of occupants. In this study, the application of the thermal comfort index as a control logic of VRF system was analyzed by field measurement. Indoor thermal environment and energy consumption characteristics according to control strategies such as set-point temperature and thermal comfort range in VRF system were analyzed. In this paper, the system configuration and the measurement results will be described.
