摘　　要：提出了以内燃机为热能动力装置的双源供暖系统,并建立了该系统的经济性评价指标数学模型。结合具体案例对影响该系统经济性评价指标的各主要因素(环境温度、热泵的COP、内燃发电机组发电效率)进行了分析。在一定条件下,该系统运行的经济性比天然气集中供热锅炉供暖运行经济性高。Puts forward a dual-source heating system with gas internal-combustion engine as thermal power equipment and establishes a mathematical model of economic evaluating indexes for this system. Applying it to an actual case, analyses the main factors--the environmental temperature, the COP of heat pump, the generating efficiency of gas internal-combustion generator--that influence the economic evaluating indexes of the system. Under certain conditions, the operating economic efficiency of this system is higher than that of natural gas-fired central heating boiler systems.
