摘要
以北京市某办公楼为例,对该办公楼采用污水源热泵系统、城市热网+冷水机组系统、城市热网+污水源热泵系统时的能耗指标、经济指标、环境指标进行计算,并应用熵权层次分析法对这3种冷、热源方案进行综合评价研究。研究结果表明,污水源热泵系统的综合性能优于其它两个冷、热源方案。在此基础上,进一步计算了污水源热泵系统的适用范围,当污水厂与建筑物的距离不超出此范围时,应用污水源热泵系统的节能环保效益较为明显。
Take an office building in Beijing as an example,the energy consumption index,economic index and environmental index of its sewage-source heat pump system,city heat-supply piping water chillers system and city heat-supply piping sewage-source heat pump system were calculated,and a comprehensive evaluation of these three cold,heat source programs by Entropy weight analysis hierarchy process was given.The research results show that the overall performance of sewage-source heat pump system is better than the other two cold,heat programs.On this basis,further calculated the application scope of sewage source heat pump system,when the distance from the sewage plant and the building does not exceed this range,the energy-saving environmental benefits of sewage source heat pump system are much more obvious.
