太阳能-桩储热技术经济性分析

Economic Analysis of Concrete Thermal Storage Piles

太阳能-桩储热技术是利用太阳能辐射和混凝土桩内埋设换热管储热,可以减少土壤源换热管打井的工作量及灌浆回填等工序。通过对太阳能-桩储热技术的经济性分析,得出该技术造价相对于土壤源热泵系统可以节省25%左右的打井费用,经济效益巨大,是高效开发与利用太阳能和地下热能的一种新方法。

Concrete thermal storage pile technology is a kind of technology,in which solar energy radiation is used and heat pump is buried in concrete piles to store heat and it can reduce soil heat pump well drilling and grout-in and backfill.Based on analysis on the economy of solar energy-concrete thermal storage piles technology,it is found out that this technology can save 25% of the cost,compared with soil source heat pump system,so the effect is great and it is also a new method of high efficiently developing and using solar energy and underground heat energy.
