内蒙古中部地区地源热泵单位井深换热量设计的研究

Designing of Average Quantity of Heat Per Meter for Ground Source Heat Pump at Central Inner Mongolia

由于地源热泵系统具有明显的地域性特点,且各地区气候地质差异较大,其设计计算不具有普遍性。通过对呼和浩特某工程地下岩土结构的实测数据的分析,重点对比了不同单位井深换热量。模拟不同条件下,地埋管换热器周围土壤的温度变化。研究不同取热量对热泵系统运行稳定的影响,以期为呼和浩特及周边地区的地源热泵的应用设计提供依据。

Ground source heat pump system is obvious in regional characteristics with larger differences of the regional geological fea- tures. Its design and calculation are not universal. Through analysis on an under-ground geological structure of the measured data in Hohhot, various overage quantities of heat per meter are compared. Different conditions are simulated, including the temperature variation of the sur- rounding soil of the ground heat exchanger. The influence of different heat on heat pump system stable running is studied, in order to provide a basis to ground source heat pump applications designed for ttohhot and the surrounding areas.
