高校浴室太阳能热水系统区域适应性综合评价

Comprehensive evaluation on regional suitability of solar water heating system in college bathrooms

为了综合评价太阳能热水系统在各城市高校学生浴室应用的适应性,提出高校浴室太阳能热水系统区域适应性综合评价方法.该方法以天然气为辅助热源的高校学生集中浴室太阳能热水系统为例,引入能效、环境、经济三方面的评价指标体系,依据数量化理论Ⅲ,建立适应性综合评价模型,并对我国33个省会城市的区域适应性进行评价.结果表明,受气象资源条件、能源市场价格、环境效益等多方面影响,高校浴室太阳能热水系统的应用具有明显的地域性差异,根据综合评价得分值将各省会城市分为五类,Ⅰ类4个,Ⅱ类7个,Ⅲ类10个,Ⅳ类9个,Ⅴ类3个,其中前3类具备应用前景,第4类城市如适当调整经济政策可以提高应用效益,而第5类城市不提倡使用.

A comprehensive evaluation method was proposed to assess the suitability of solar water heating system applied in college bathrooms in different cities.Solar water heating system with natural gas as the supplementary heat source was taken as an example,and an evaluation indices system was established in three aspects of energy efficiency,environmental and economic benefits.A comprehensive evaluation model was developed based on Quantification Theory Ⅲ,and the evaluation of the regional suitability of solar water heating systems in college central bathrooms was conducted for 33 provincial capital cities of China.Results show that the application of solar water heating systems in college central bathrooms bears distinct regional differences due to influences of meteorological resources,energy prices and environmental benefit.The provincial capitals are divided into 5 categories in accordance with the scores of comprehensive evaluation.There are 4 cities classified in the first category,7 in the second category,10 in the third category,9 in the fourth category,and 3 in the fifth category.The cities in the first three categories have apromising application prospect,and the fourth will generate more benefits if appropriate economic policy adjustments are made,while the fifth is not advocated.
