Description
Urumqi is located in Xinjiang province the cold climate zone in China; the heating period in winter is 6 months. The local solar energy is abundant, up to5.4×103-5.8×103MJ/(m2.Y) which can provides advantage condition for utilization of solar energy. However, heat supplied by the solar collector determines the useful solar energy proportion for heating terminal. During the high solar radiation intensity period, the choice of the collector according to local climatic conditions and the utilization of phase change thermal storage facility impact the improvement of solar energy efficiency directly. This research established a solar energy-phase change storage-floor radiant heating combine-system in an office in Urumqi. The influence on thermal efficiency of solar collector including outdoor weather condition (solar radiation intensity, temperature, wind speed etc.), inlet and outlet water temperature, connect method during local heating period and thermal performance of this combine-system was developed experimentally. The research result provides a reference for optimization design of this kind of system.
