中文摘要：

本文对00100102.7号专利提出的“双源可逆型供暖系统”进行了比较深入的剖析，认为这一方案与常规锅炉方案相比，节能效果显著；与电驱动热泵供暖方案相比，可靠性高；与热电联产方案相比，由于终端产品单一，所消费的一次能源量要大幅度地减少，与热电联产方案另一不同点是摆脱了所谓“上网问题”的困扰，实在是一种值得关注的城市天然气消费方式。

英文摘要：

Dual Source Heating （Air Conditioning） System is a system proposed in patent 00100102.7. A full exposition of its performance is presented in this paper. It is found that in comparison with conventional system it consumes far less fossil fuel. Against the electrically driven heat pump, it provides a more reliable operation. Unlike CHP （Combined Heat ＆ Power）, the problem of interconnection with public power grid does not exist. In addition, to meet a specified heat load, the amount of natural gas needed to feed the system is remarkably reduced than that needed for cogeneration system. This is important because in China natural gas is relatively scarce and the peak demand appears normally in heating seasons.
