| 中文摘要 | 结合土壤耦合热泵技术与冰蓄冷技术的特点,并在土壤蓄冷与土壤耦合热泵集成系统构想的基础上,建立了考虑土壤周期性冻融相变的土壤蓄冷、释冷过程的数学模型,并采用数值方法进行求解。通过建立模拟土壤蓄冷、释冷过程的砂箱试验台并由试验测试结果表明:所建模型的计算结果与试验数据吻合较好,二者偏差在10%以内。应用本文所建数学模型可对土壤蓄冷系统的蓄冷、释冷运行特性进行计算与分析,并为该集成系统的应用提供理论支持与技术储备。; Combined the advantages of ground-coupled heat pump and ice cool storage technology,and based on the integrated system of cool thermal storage in soil and ground-coupled heat pump,a mathematic model of cool thermal charging and discharging process in soil was established,which considers the cyclic phase change of the moist soil.Moreover,the numerical simulation and experimental validation were performed,the results indicate that the simulation and experiment are consistent with each other and the error is less than 10%. The model can be applied in the numerical calculation and theorical analysis of the cyclic soil cool charging and discharging performance,and will provide theory support for the application of the integrated system.; 国家自然科学基金(No.50378024) |
