摘要
提出一种单、双级空气源燃气机热泵,并从多个角度上同传统的蒸汽压缩式热泵和单级燃气机热泵作了比较。结果表明,这种热泵在一次能源利用率、火用效率和经济性上有较大优势,它的推广使用将扩大热泵的适用范围和使用时间,尤其在三北地区。
A single/double stage air-source heat pump driven by gas engine is put forward.And the comparison of this kind of heat pump with the traditional vapor compression heat pump and with the single-stage heat pump driven by gas engine is proceeded in several aspects.The calculation results show that this kind of heat pump has evident predominance in primary energy ratio,the exergy efficiency and the economy.Its utilization will improve the working condition and the applicability of heat pump,especially in the north area of China.
