浅层地温能作为清洁、可再生的新型能源,对解决能源短缺、温室气体排放等问题有很大帮助。在分析贵阳市土壤源浅层地温能赋存条件、现场热响应试验的基础上,获得了区内热物性参数、地层的热效应试验特征。利用层次分析法对土壤源浅层地温能进行了适宜性分区,并以此为基础计算了贵阳市浅层地温能的总换热功率和开发利用潜力。贵阳市土壤源浅层地温能如能充分的开发利用,则冬季可供暖面积1.95×108 m2,夏季可制冷面积1.95×108 m2,推广和利用浅层地温能对贵阳市经济的快速发展具有重要意义。
Abstract
Shallow geothermal energy(SGE),as a new kind of clean and renewable energy,can be used to solve energy shortage,emission of greenhouse gas,etc.On the basis of in-situ thermal conductivity test,the reserve condition of SGE in Guiyang was analyzed,and thermal parameters of the region in association with test data of stratum thermal effects were obtained.According to analytic hierarchy process(AHP),suitability classification was carried out for SGE from soil.Furthermore,we calculated the total heat power and the potential of development and utilization of SGE in Guiyang.Results show that,on the supposition of full utilization of SGE from soil in Guiyang,in the winter,we can supply heating for area of 1.95×108 m2;while in the summer,we can cool the identical area.In light of this,it is very significant to promote the utilization of SGE in Guiyang.
