【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。更多还原

【Abstract】 The composite central heating mode using high temperature hot water provided by central heating system todrive absorption heat pump for extracting shallow geothermal was proposed. Through the comparison of the primaryenergy utilization efficiency and economical analysis etc.,the research results show that comparing with theconventional heat-power combination central heating mode,the heating capacity of the new central heating system can begreatly improved and the heating costs can be largely reduced without expanding the capacity of heat resource andincreasing energy consumption of system. Also,compared with electric-driven ground source heat pump heating mode,the new central heating mode utilized high temperature hot water provided by primary heat supply network to replace thehigh grade electricity as the driven heating resource to work,which can decrease sharply the electricity consumption andrealize graded use of energy. The heating mode with absorption ground source heat pump have many advantages formeeting same heat supply conditions,such as lower primary energy consumption,lower heat transfer area ofunderground pipe,smaller underground heat in winter season and better for winter and summer soil heat balance.更多还原
