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。
On the basis of analyzing the advantages and disadvantages of the methods of solar energy assurance and soil heat balance which are commonly used in the research, the improved heat balance method is put forward, taking into account the system operation mode, soil natural recovery capability and economic factors. TRNSYS simulation software was used to verify the effect of the improved heat balance method in maintaining soil accumulation and exothermic balance. The results show that the soil temperature drop (0.38 ℃) after the continuous operation of 15b in the improved heat balance method is lower than that of the original method (0.99 ℃), and the improved method is more effective in maintaining soil accumulation and exothermic balance.
