摘　　要：针对寒冷地区冬季地表水水温过低和干渠污水水流量不足等水源状况,提出了新型采集凝固热热泵技术,即在高峰热负荷下采集水源的凝固热为建筑物供热.为有效地提取凝固热,在介绍专用设备凝固换热器原理的基础上,初步分析了热泵系统的重要参数及综合性能指标.对4个典型城市的应用分析表明,采集凝固热热泵系统供热季节性能系数在4.05～4.22,其供热性能虽比常规水源热泵系统差些,但较燃煤锅炉或热网供热系统仍有较大优势.For the conditions of the low winter surface water temperature and insufficient sewage flow in cold areas,a new heat pump technology with freezing heat collection is put forward,which makes the freezing heat of water to be used for building′s heating at the peak heat load.To effectively collect the freezing heat,a special device named the freezing heat exchanger is introduced.On the basis of the preliminary analysis of device,the important parameters and the integrated performance indexes in the heat pump system are discussed.Application results show that the heating seasonal performance factor of this heat pump system is between 4.05-4.22 for four typical cities,and its heating performance is worse than that of conventional water-source heat pump system,but better than that of coal-fired boiler or heating network system,so this new system has a greater advantage.
