摘　　要：太阳能热水系统冬季防冻措施多样,但尚缺乏对防冻措施选择策略、选择依据及综合评价的研究。文章以防冻液、管路排空、电辅热带、定温循环和滴水防冻共5种常用防冻措施为例,利用层次分析理论综合考虑系统经济性、稳定性、防冻效果等因素,选择出合适的防冻措施单项评价指标,并建立了太阳能热水系统防冻措施综合评价模型。文章提出了5种防冻措施在不同指标评价下综合性选择方法,可为北方寒冷地区选择适宜的太阳能热水系统防冻措施提供依据。There are various anti-freezing measures for solar water heating systems in winter,but there is still a lack of research on the selection strategy,selection basis and comprehensive evaluation of anti-freezing measures.In this paper,five commonly used antifreeze measures,including antifreeze,pipeline emptying,electric auxiliary heating,constant temperature circulation and dripping antifreeze,are used as examples.The hierarchy analysis theory is used to comprehensively consider factors such as system economy,stability,and antifreeze effect,and select the appropriate antifreeze.Measures individual evaluation indicators,and established a comprehensive evaluation model of antifreeze measures for solar water heating systems.The research has formed a comprehensive selection method of five anti-freezing measures under different index evaluations,which can provide a basis for choosing suitable anti-freezing measures for solar water heating systems in cold northern regions.
