Study of allocation proportion for combined heat-supply system based on groundwater source heat pump and boiler plant in Shenyang area

Taking the combined heat-supply system of a residence community in Shenyang based on groundwater source heat pump and boiler plant as the research object, analyses the energy consumption combined with the heat load duration graph and performs the economic analysis with the annual cost method. Obtains the best allocation proportion of the combined heat-supply system. The results show that the annual cost of the combined heat-supply system is the lowest when the auxiliary coefficient is 0.46. Its energy saving perfromanceis very well. This kind of heating supply way should be introduced in suitable area.
