Based on air heat(cold)transfer method of sewage water source heat pump,this paper discussed on the heating characteristics of new sewage water source heat pump,and set up a test table.Analyzed the effect of some influence parameters on heating characteristics of heat pump system.Sewage temperature and flow rate had a significant impact on the heat transfer effect of the new sewage source heat pump system.The physical parameters of air had some influence on the operating characteristics of the new sewage water source heat pump system.The density of the air diffuser has a great influence on the operating characteristics of the new type of sewage water source heat pump system.However,the influence of structural type and installation depth was relatively weak.The efficient heat transfer technology of the new system not only made use of the sensible heat of sewage,but also the latent heat of air and sewage,and energy-saving effect was remarkable.
