            大慶地區地埋管地源熱泵對土壤溫度場的累年影響

            摘要:

             為研究適宜大慶地區地埋管地源熱泵系統的運行方案,利用TRNSYS軟件模擬了大慶地區某建筑的全年動態負荷和地埋管地源熱泵不同運行模式、不同地埋管間距情況下土壤溫度場及系統COP。模擬結果表明,大慶地區土壤溫度恢復速率為0.45 ℃/月,在考慮土壤溫度自身恢復和經濟性的情況下,該地區冷熱負荷相差25倍的建筑的地埋管間距應設置為6 m。若在類似大慶的嚴寒地區使用地埋管地源熱泵系統對建筑供暖供冷,應適當增加地埋管間距并增加輔助裝置來消除土壤熱失衡。

            Abstract:

             In order to study the operation scheme of ground-source heat pump systems, simulates the annual dynamic load of a building, and the soil temperature field and system COP under different operation modes and different spacing of buried pipes of the ground-source heat pump in Daqing. The simulation results show that the soil temperature recovery rate is 0.45 ℃ per month. Considering the soil temperature recovery and economics, the spacing of buried pipes of buildings with 25 times of difference between cooling and heating loads should be set to 6 m. If a ground-source heat pump system is used for building heating and cooling in a severe cold zone like Daqing, the spacing of buried pipes should be increased and auxiliary devices should be added to eliminate the soil thermal imbalance.
