To address the technical problem of efficient operation for the heating system coupling an air-source heat pump with a gas-fired heating and hot water boiler, this paper proposes a system operation control method based on the analytic hierarchy process (AHP). By establishing a mathematical model of the air-source heat pump coupled with a gas heating system, the hourly operational performance of the system is calculated, and a comprehensive evaluation index system for the coupled heating system is determined. The AHP is used to calculate the index weights and construct a comprehensive objective function. Based on the mathematical model, the comprehensive objective function under different temperatures is calculated, and the operation mode with the maximum comprehensive objective function is adopted to obtain the operation control strategy for the coupled heating system. The results indicate that adopting this method can enhance the system’s energy utilization efficiency, reduce costs, and achieve efficient, energy-saving, and environmentally friendly operation of the coupled heating system.
