摘　　要：基于典型气象数据,利用所建数学模型对丽江市阳台壁挂式平板型太阳能热水器的水量配比进行了计算.结果表明,春、夏、秋、冬四季和全年的水量配比分别位于28.1~43.5,21.6~35.3,35.1~45.4,47.3~57.3和33.0~45.4kg/m2之间.为便于应用,文中给出了正南向季均和年均水量配比(Vt/Ac)n与β间相关系数大于0.99的回归关系式.理论分析显示,方位角≤20°,30°,40°时,方位角对水量配比的影响约为5%、10%和15%,对应季均和年均水量配比的方位角因子分别位于0.95~1.00,0.91~1.00和0.85~0.99之间.The tank-volume-to-collector-area ratio（the ratio is expressed as Vt/Ac）of the balcony wallmounted flat-plate solar water heaters has been calculated by means of the established mathematical model and the typical meteorological data of Lijiang.The results show that the range of Vt/Ac for spring,summer,autumn and whole year is 28.1-43.5,21.6-35.3,35.1-45.4,47.3-57.3 and 33.0-45.4 kg/m2,respectively.For convenience of application,regression relations between seasonal and annual average（Vt/Ac）n andβfor solar water heater with the south-facing solar collector are built and their correlation coefficient is more than 0.99.By theoretical analyses,it has been found that the azimuth angle has about5%,10%and 15%effect on the seasonal and annual average Vt/Acwhen the azimuth angle is less than or equal to 20°,30°and 40°.The corresponding azimuth angle factors of Vt/Acare respectively in 0.95-1.00,0.91-1.00 and 0.85-0.99.
