摘　　要：沼气发动机驱动的热泵(BHP)是一种节能环保型装置,与电动压缩式热泵相比,其主要动力源不同。该装置能充分回收利用沼气发动机余热。通过对BHP系统的构建及一次能源利用率(PER)的计算,分析了BHP系统的经济性及其对环境保护的作用。结果表明:不论从节能还是从环保方面考虑,BHP系统都具有明显的经济价值和环保效益。Biogas engine driven heat pump（BHP）is a kind of heating equipment for energy saving and environmental protection.Compared with motor-driven compression heat pump,BHP has similar main components but distinct power source and it can recover waste heat from biogas engine.In the paper,the system construction of BHP is developed,the primary energy ratio （PER）is calculated by comparison with other heating equipments,and the economic analysis together with its effect on environmental protection are given out.The results show that BHP system has great economic values either in energy-saving or environmental protection.
