摘　　要：地源热泵利用地下浅层地热资源作为热源,由于较深的地层中在未受干扰的情况下常年保持恒定的温度,既高于冬季的室外温度,又低于夏季的室外温度,因此地源热泵可克服空气源热泵的技术障碍而且效率大大提高。土壤的原始地温,既是计算地源热泵系统地下埋管换热动态过程的原始条件,也是地源热泵系统设计计算的依据。通过为期一年的原始地温测试在整理和分析大量实验数据的基础上,可以得到利用线性加权和法确定土壤的平均原始地温,与实测值相比非常接近。GSHP makes use of shallow geothermal resources as heat source. The temperature m aeep ground is invariableness by not being disturbed. It is higher than air temperature in Winter and lower than air temperature in Summer. GSHP＇s efficiency is much higher than air-source heat pump. Original ground temperature is the first condition in calculation and design of GSHP system. In the base of mass experiment and analysis in a year, we can see that using linearity add method to confirm original ground temperature is very close to measured values.
