Taking the air conditioning cold and heat sources of comprehensive building complex of an airport in the hot summer and cold winter zone as the research object, under the conditions of the existing energy structure, comprehensively considering the factors such as environment, investment, benefits and energy saving, this paper proposes a multi-energy complementation composite system design scheme and control strategy that couples ground-source heat pumps with water energy storage and conventional energy sources. A quantitative and qualitative analysis study is conducted based on the analytic hierarchy process (AHP) in order to establish a comparison and selection evaluation model of multi-energy complementation systems, providing a reference for the early feasibility study of multi-energy complementation energy supply systems.
