区域型冷热电三联供系统节能性分析——以上海世博后续开发A、B片区应用为例

Energy-saving research of district cooling heating and power systems:a case study of Shanghai post-expo region A and B

以节能率为评价区域型冷热电三联供系统的节能性指标,分析了节能率影响因素,并以上海世博后续开发中区域型冷热电三联供系统为应用案例进行分析。系统应保证较高的发电效率及余热利用效率,且冬季应尽可能采用热泵技术,以充分发挥系统节能性。

Energy saving ratio was employed as an energy saving index to evaluate District Cooling Heating and Power （DCHP）system and the impact factors were analyzed. Also the im-plementation of DCHP system into Shanghai post-expo was evaluat-ed as an example. In order to ensure energy saving ratio of DCHP system,high efficiency of power generation and waste heat recov-ery should be guaranteed,and heat pump technology should be ad-opted as far as possible in winter.
