土壤源热泵夏季制冷对土壤碳含量影响的实验研究

Experimental Study on the Effect of Summer Cooling by Soil Source Heat Pump on Soil Carbon Content

通过搭建土壤源热泵夏季制冷向土壤输送热量实验台,使土壤温度升高,当土壤热扩散半径为1m、2m时,取1m、2m处土样测单位质量土壤有机碳含量、总碳含量和无机碳含量,分别与对照组即同时间段且没有人为加热自然状态下的土壤样品的有机碳含量、总碳含量和无机碳含量做对比,得出土壤作为空调冷源温度升高时土壤碳含量下降、且对土壤有机碳含量的影响比对土壤无机碳含量的影响显著的结论。

In this paper,by simulating the soil source heat pump summer cooling experiment that soil as a cold source of air conditioning,so that the soil temperature increases,when the soil heat diffusion radius of 1m,2m,take 1m,2m at the soil samples to measure the unit mass of soil organic carbon content,total carbon content,inorganic carbon content,respectively,and the control group,namely,the same period of time and the absence of man-made heating of the natural state of the soil samples of the organic carbon content,total carbon content,inorganic carbon content to do comparisons,the conclusion that the soil as a cold air conditioning source of the soil temperature increases the decline in the content of soil carbon,and the impact on the content of organic carbon in the soil is more than the effect on the content of inorganic carbon of the soil significant conclusions.
