中文摘要	在对土壤蓄冷系统冷量损失过程分析的基础上,提出了地下埋管换热器垫层冷量损失与温差传热冷量损失的概念,并建立了垫层冷量损失和温差传热冷量损失的计算模型;为衡量系统在运行期间地下埋管换热器管束系统的运行效率,建立了埋管换热器管束系统的平均释冷率模型。通过理论研究与模拟计算,分析了土壤初始温度、埋管间距及管束结构对土壤蓄冷系统冷量损失的影响,指出了土壤蓄冷系统冷量损失随土壤初始温度及埋管间距之间的变化规律,为土壤蓄冷系统地下埋管换热器的优化设计提供理论依据。; Based on the analysis of the cool loss process of cool storage system in the soil,the concepts of underLayment cool loss and heat transferred cool loss were presented,and the calculated models of underlayment and heat transferred cool loss of underground heat exchangers were established.Moreover,in order to evaluate the operation efficieney of the buried pipe bundles,the average cool discharging factor model of the underground heat exchangers system was set up. Through the theoretical analysis and simulation,the influences of the initial soil temperature,pipe distance and pipe bun- dle structure on cool loss of the soil cool storage system were analyzed and the cool loss change rules with soil initial tem- perature and pipe distance were put forward,and these will provide theory proofs for the optimal design of underground heat exchangers of the soil cool storage system.; 国家自然科学基金(50378024)
