【摘要】 结合逸夫图书馆的使用特性,比较分析了三种冷热源方案,最后采用了浅层湖水源热泵的方案;文章介绍了该方案水系统流程和取水系统的设计及其采用的节能和自控措施。工程竣工后,系统运行良好,但由于采用了浅层湖水,也存在相关的问题,如水源侧温度升高等。但综合来说,对于学校类图书馆建筑,可以采用浅层景观水作为冷热源。 【Abstract】 Combining with the characteristics of Yifu library,the three kinds of cold and heat source schemes was compared and analyzed.And the lake water source heat pump system was adopted at last.In the paper,the water system and water intake system were introduced,and also the energy-saving and self-control measures.After completion of the project,the system works well,but due to the shallow lake,there are also related issues,such as temperature raising in the water source side.In summary,for the library buildings in school,the shallowlandscape water can be used as cold and heat source for the air conditioning system. 【关键词】 水源热泵; 景观水; 乙二醇 【Key words】 heat pump system; shallowwater; ethylene glycol
