摘要
本文对长春某土壤源热泵系统运行数据进行了研究,该系统采用面积补偿法缓解严寒地区地下土壤冷堆积(温度衰减)问题.为测试和验证面积补偿法的实际效果,作者于2017年冬季增加了该系统的供暖面积,使其与该系统的夏季供冷面积相等,在此基础上,对该系统2014-2017年冬季地温数据进行了测试采集,并将2017年冬季数据与2014-2016年冬季数据进行了比较,分析研究了其地温变化规律.此外,还计算分析了该系统2014-2017年冬季性能系数(COP),并根据其地温及COP的变化,验证了面积补偿法的实际效果.结果表明,2014-2016年冬季地温、COP略有衰减且基本保持稳定,但2017年冬季增加供暖面积后,与2014-2016年冬季相比,其地温、COP明显降低.
The operation data of the soil source heat pump system in Changchun was studied.The area compensation method of the system was used to alleviate the problem of cold accumulation(temperature attenuation) of underground soil in severe cold regions.In order to test and verify the actual effect of the area compensation method,in the winter of 2017 the author increased the heating area of the system and made the heating area equal to the summer cooling area of the system.On this basis,the underground soil temperature data of the system in the winter of 2014 to 2017 were tested and collected,the data in the winter of 2017 was compared with those in the winter of 2014-2016,and its underground soil temperature change rule was analyzed and studied.In addition,the coefficient of performance(COP) of the system in the winter of 2014-2017 was also calculated and analyzed,and the actual effect of the area compensation method was verified according to the change of its underground soil temperature and COP .The results show that the underground soil temperature and COP in the winter of 2014-2016 decrease slightly and basically remain stable,but after the heating area was increased in the winter of 2017,the underground soil temperature and COP decrease significantly compared with those in the winter of 2014-2016.
