沼气机压缩式热泵系统的构建与经济性分析

由沼气发动机驱动的热泵（BHP）除能够保证一般热泵功能外，还能够充分回收利用沼气发动机的余热。根据对BHP的系统构建及一次能源利用率（PER）的计算结果，分析BHP系统的经济性及其对环境保护的作用。结果表明：BHP系统在经济性及环保方面都具有明显的经济价值和现实意义。

System construction and economic analysis of heat pump driven by biogas engine

Biogas engine-driven heat pump（BHP）not only has the same functions of compression heat pump, but also can utilize the waste heat recovery from biogas engine. According to the system construction of BHP and its calculation of the primary energy ratio（PER ）compared with other heating equipments, analyzes the economic analysis together with its effect on environmental protection. The results show that BHP system has great economical value either in terms of energy-saving or environmental protection.
