摘　　要：以福州地区典型气象年逐时气象数据为基础,对平板型太阳热水器的热性能进行逐时模拟。利用综合能源价格法,分析集热器面积对太阳热水器经济性的影响,并比较各类热水器的技术经济性。在当前能源价格体系下,集热器面积为8.5m^2时,系统的年平均太阳能保证率最大(为67.72%);集热器面积为4m^2时,综合能源价格现值最小(为0.283$/kWh),此时系统的年平均太阳能保证率为62.65%。Based on hourly meteorological data of typical meteorological years in Fuzhou, the thermal performance of fiat plate solar water heater has been hourly simulated. By synthetic energy price, the effect of collector area on the economy of solar water heater was analyzed; also the economic comparisons of various types of water heaters were discussed. Under the current energy price system, the maximum annual average solar fraction of 67.72% was obtained when the collector area is 8.5m^2 ; the minimum present value of synthetic energy price of 0. 283 ￥/kWh was obtained when the collector area is 4In2, with the annual average solar fraction of 62.25 %. With the increase of energy price, the economic superiority of solar water heater is more significant. The simulation and analysis results have important reference value for optimizing the design of solar water heater and guiding the technical progress of water heaters.
