【摘要】：提出一种利用集中供热系统提供的高温热水驱动吸收式热泵机组提取浅层地热的复合型集中供热方式。通过一次能源利用效率、经济性分析等角度比较可知,相对常规热电联产集中供热方式,该方式可在集中供热系统热源不扩容、系统能耗不增加的前提下大幅提高原供热系统的供热能力,降低供热成本;相对电驱动土壤源热泵供热方式,该方式采用一次热网提供的高温热水作为驱动热源做功,替代高品质的电做功,可大幅减少耗电量,更好地实现能源梯级利用。在满足相同供热量条件下,吸收式土壤源热泵机组供热方式具有一次能耗低、地下埋管换热面积小、冬季地下取热量小和利于冬夏土壤热平衡等优点。
[Abstract]:In this paper, a complex central heating system based on high temperature hot water driven absorption heat pump for shallow geothermal extraction is proposed. Through the comparison of primary energy efficiency and economic analysis, it can be seen that compared with conventional cogeneration central heating mode, this way can not be expanded in the heat source of central heating system. On the premise of no increase in energy consumption, the heating capacity of the original heating system is greatly improved, and the heating cost is reduced. Compared with the ground source heat pump heating mode driven by electricity, this way uses the high temperature hot water provided by the primary heating network as the driving heat source to do the work. Instead of high-quality electrical work, power consumption can be greatly reduced and energy cascade utilization can be better realized. Under the same heat supply condition, the heat supply mode of absorption ground source heat pump unit has the advantages of low primary energy consumption, small heat transfer area of underground buried pipe, small underground heat collection in winter and favorable soil heat balance in winter and summer.
