Study on Heat Charge and Discharge Performance of Phase Change Thermal Storage in Solar Energy-Fresh Air Heating System

摘要

The performance of a system combined solar energy, phase change thermal storage and fresh air heating is studied in this paper. Based on the experimental data from Nov 2008 to Mar 2009, it is mainly focused on how the heat charge and discharge performance are influenced by the inlet temperature, flow velocity of heat transfer fluid and installing mode of the phase change thermal storage equipment, etc. Furthermore, the main heat charge and discharge performance of the phase change thermal storage equipment are analyzed by numerical calculation method, which will provide references for the system optimization.
