摘　　要：为研究季节性冰雪蓄冷技术在建筑空调中应用的可行性,在稳态传热及集总参数分析方法基础上,建立了圆柱形地下储库冰雪储存与释冷过程的数学模型,并得出模型的分析解。运用该模型对北京市商场、办公楼、宾馆和医院四类典型建筑应用季节性冰雪蓄冷技术进行空调供冷的特征参数进行了计算。提出了冰雪蓄冷匹配系数的定义,分析了其在不同储冰初始温度及年平均单位面积冷负荷条件下的变化规律。计算表明,冰雪蓄冷匹配参数主要受年平均单位面积冷负荷影响,而受储冰初始温度影响较小。To study the feasibility of seasonal snow and of ice thermal storage technology applied in building air conditioner,the mathematical model of a cylindrical underground storage snow and ice thermal storage and release was established based on the steady-state heat transfer and lumped parameter analysis method,and the analytical solution of the model presented.The cooling characteristic parameters were calculated and analyzed with the seasonal snow and ice storage technique in four typical buildings which were departments,offices,hotels and hospitals in Beijing.The matching coefficient of snow and ice thermal storage was defined and the performance under different initial ice storage temperatures and the annual average cooling load per unit area were analyzed.The results show that the matching coefficient of snow and ice thermal storage is mainly affected by the annual average cooling load other than the initial ice storage temperature.
