Abstract: In order to study the operating characteristics of the solar heating system in the plateau region, the TRNSYS simulation model of the solar energy heating system in Hongyuan Airport was established, and the validity of the model was verified by the measured data. The efficiency of the collector, the temperature of the storage tank and the running time of each mode were analyzed by running the simulation model. The results show that the maximum daily collector efficiency is 0.40, the average value of heating is about 0.3; the temperature of regenerator in 50 ℃ and above is 5 ~ 6 hours in December and January, And the Initial period and the final phase of heating can reach up to 13 to 15 hours . The direct solar heating, heat pump heating and the combined heating mode are 40.76%, 37.03% and 22.21% of the total heating time respectively. The results provide a reference for the application of solar heating system in high altitude and cold regions.
