摘　　要：搭建了热管式真空管太阳能集热装置供热性能测试平台,基于EES软件,建立了热管式集热装置供热性能仿真模型,试验验证了模型的正确性。分析了太阳能集热热水温度、集热效率、供热性能、贡献率等参数的变化规律。研究表明:太阳能集热效率和集热量随时刻的变化先上升后下降,集热效率最大达0.62、集热量最高可达8.02 k W。该系统对郑州地区某200 m2别墅供暖,11月至次年3月份的月平均供暖贡献率在40%~78%之间波动,平均值为54%,最大值达78%。An experimental heat pipe evacuated tubular solar collector system and the simulation model based on the software EESare established, and the correctness of the simulation model was verified with experimental data. The hourly heat collector efficiency, heat-collecting capacity and solar collector system contribution rate based on typical day about Zhengzhou have been calculated. Research shows that： the hourly heat collector efficiency and heat-collecting capacity increases initially and then decreases, the maximum heat collector efficiency and heat-collecting capacity are 0.62 and 8.02 kW respectively. Research also showed that solar collector system can provide 40% to 78% heating load for the villa with 200m2 in Zhengzhou from November to March.
