摘　　要：集热器面积的选择是太阳能供暖系统设计的关键,本文对太阳能-电辅热供暖系统进行了技术经济分析,建立了系统费用年值与集热器面积函数关系的数学模型,分析探讨了使费用年值最小的集热器面积的计算方法。并以太原为例(100m2住宅)逐日进行了计算,结果表明当集热器面积为21.34m2,整个系统的费用年值最小;整个采暖季的太阳能保证率为60.24%。Collector area is the key to a solar heating system while designing. In this paper, the technical-economic analysis of a solar-electric auxiliary heating system was carried. The mathematical model of the functional relation between the annual system cost and the collector area was established, and the calculating method of collector area based on the minimum annual cost was discussed. Taking a 100m^2 residential in Taiyuan as an example, the result of daily calculation shows that the annual cost of the system is minimum when the collector area is 21.34m^2. The solar fraction of the whole heating season is up to 60.2%.
