燃气内燃机双源供暖系统的研究
Study on dualsource gas internalcombustion engine heating systems
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。

Abstract：
Puts forward a dualsource heating system with gas internalcombustion 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 internalcombustion 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 gasfired central heating boiler systems.
