摘　　要：在对研究中常用的太阳能保证率法、土壤热平衡法的优缺点进行分析的基础上,将系统运行模式、土壤自然恢复能力、经济性因素考虑在内,提出改进的热平衡法。采用TRNSYS模拟软件对改进的热平衡法在保持土壤蓄、放热平衡方面的效果进行验证。结果显示,改进热平衡法相应复合式系统15 a连续运行后土壤温降(0.38℃)较原方法(0.99℃)减小,改进法在保持土壤蓄、放热平衡方面的效果更好。An improved method based on the analysis of the solar fraction method and the heat equilibrium method was presented. Then the practicability of the improved method was verified by simulation of a TRNSYS model of the solar assisted ground resource heat pump system. The simulation results show that the average soil temperature decrease of improved heat balance method （0.38 ℃） is smaller than that of the original method （0.99 ℃） after 15 year＇s continuous operation, and this suggests that the improved heat balance method is better the original method in keeping the soil heat balance.
