Nowadays,environmental pollution and energy crisis have become major issues that all humanity must face and solve. As for the heating industry,people not only need high-quality heating,but also have higher requirements for environmental protection,energy conservation,and safe and civilized production. Regenerated water source heat pump technology is a representative heating and air conditioning technology with low energy consumption that meets the above requirements. A retrofitting project of a heating center in Beijing is analzyed,starting from the single stage heat pump technology route,comprehensively considering three resource forms:regeneration water waste heat resources as the main,flue gas waste heat,and steam waste heat as auxiliary,using electrically driven centrifugal heat pump equipment,relying on two peak shaving measures of steam water heat exchangers and hot water boilers,to demonstrate the technical and economic feasibility of various schemes. Suggestions for the comprehensive utilization of recycled water waste heat resources are proposed,which are safe,reliable,economically efficient,environmentally friendly,energy-saving,and low-carbon.
