| Abstract: | 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. |
