【 摘 要 】

A mathematical model was set up to simulate the heat transfer process and performance of the molten salt phase change heat storage tank of the solar power and cooling system driven by Solar thermal power generation system. Meanwhile, an experiment is also built to validate the model. For this thermal storage tank, mature industrial intermediate-temperature ternary salt is selected. ANSYS software is utilized to simulate the performance of heat transfer process of phase change based on the enthalpy method. Heat transfer characteristics and factors are analyzed according to the results of the simulation and experiment. The results shows that the data coming form the simulation and the test fit each other well and the simulation is acceptable.
