摘　　要：利用所建立的数学模型,基于昆明典型气象数据,对应用在昆明地区的阳台壁挂式平板型太阳能热水器的水量配比进行了计算。按方位角为0°的计算结果显示,月均、季均和年均水量配比随倾角的增大逐渐减小。当方位角为10~90°时,3~9月与10~翌年2月,倾角60~90°所对应的月均水量配比的方位角因子分别为0.66~1.00与0.52~0.99。当方位角≤20°时,方位角对季均和年均水量配比的影响约为5%。春、夏、秋3季的水量配比和年均水量配比的方位角因子为0.73~1.00;冬季水量配比的方位角因子为0.58~0.99。当方位角≤50°时,春、夏、秋3季和年均水量配比的方位角因子为0.90~1.00;当方位角≤30°时,冬季水量配比的方位角因子为0.90~0.99;此时方位角对水量配比的影响小于10%。The tank volume-to-collector area ratio （the ratio is abbreviated as V,/Ac） for balcony wall-mounted tim-plate solar water heaters is calculated by using the established mathematical model based on the typical meteorological data of Kunming. Calculation results with the azimuth angle of 0 o show that monthly, quarterly and annual average VJAc decreases with the increase of the tilt angle. When the azimuth angle increases from 10° to 90 °, the azimuth angle factors of monthly average V/Ac are respectively 0.66~1.00 and 0.52-0.99 from March to September and from October to February with tilt angles of 60-90 °. The azimuth angle has about 5% effect on the quarterly and annual average V/Ac when the azimuth angle is less than or equal to 20 °. In addition, the azimuth angle factors of V/Ac for spring, summer, autumn and whole year are 0.73-1.00. The value range for winter is 0.58 ~0.99. Moreover, the azimuth angle factors of V/Ac for spring, summer, autumn and whole year are 0.90~1.00 when the azimuth angle is less than or equal to 50 o. The value range for winter is 0.90-0.99 when the azimuth angle is less than or equal to 30 °. The azimuth angle effect on Vt/Ac is less than 10%.
