Abstract: Based on the real solar heating system with seasonal heat storage,a one-dimensional transient model of the solar receiver with non-uniform heat flux distribution was developed. The model is dynamically validated by the experimental data. Results show that the experimental value of the outlet temperature of the receiver was in good agreement with the simulation results,The maximum deviation is not more than 5%. The thermal performance of the tower system decreases slightly with the increase of the inlet fluid temperature,when the inlet temperature is higher than 60 ℃,the thermal performance of the tower system is better than that of the flat plate and vacuum tube collectors. This research provides an important theoretical basis and experimental reference for the application of the concentrating system in the field of medium and low temperature.
