摘要
针对目前太阳能热水系统经济性评价方法的单一性,引入热水成本单价对太阳能热系统进行经济性分析.以上海市典型一家三口家庭为实例,基于TRNSYS软件模拟分析上海地区太阳能集热器出口温度,计算出不同辅助能源时太阳能热水系统的热水单价,结果表明:以电辅助太阳能热水系统的热水单价为146.75元/吨,相对燃气作为辅助能源,其热水单价减少40.2%.
Aiming at the singleness of current economic evaluation method of solar hot water system,the cost unit price of hot water was introduced to analyze the economic efficiency of solar thermal system.Taking a typical family of three in Shanghai as an example,the outlet temperature of solar collector in Shanghai area was simulated and analyzed based on TRNSYS software,and the hot water unit price of solar hot water system with different forms of auxiliary energy was calculated.The results show that the hot water unit price of electric assisted solar water heating system is 146.75 yuan per ton,which is 40.2%less than that of gas assisted solar water heating system.
