摘要
本文将广州地区与另两类不同气候类型地区的埋地管换热器的换热性能进行了对比分析。结果表明,放热性能,广州地区比其它两类地区低;取热性能,广州处于中间位置。文中给出了取放热时,广州与另两类地区埋管换热器换热能力的相对大小数值,可为不同地区埋管换热器的设计提供参考。
The performance of heat transfer of underground heat exchangers in Guangzhou was investigated and compared with those of two other climate regions,including three cities, Shenyang,Shanghai and Qingdao. The results indicate that the heat discharge in Guangzhou is the lowest of all in Summer. And the charge heat in Guangzhou is medium among the three regions. This paper gives the relative value of the heat capacity between Guangzhou and other two regions in heating and cooling operation and it is valuable for designing underground heat transfer in other different cities in the above regions.
