Abstract: A biogas engine driven heat pump system for comprehensive utilization and conservation of energy is presented. An experimental platform was constructed and the system performance was tested. Based on theoretical analysis and experimental data, the relationship between load rate of biogas engine and biogas consumption, waste heat recovery, system coefficient of performance (COP) and primary energy ratio (PER) was studied. Results indicate that the partial load performance of this system is good, with the maximum COP of 4.18 and the maximum PER of 1.4 for recovering the waste heat of biogas engine exhaust fume only. Therefore, the biogas engine driven air source heat pump system can significantly improve heating capacity and lower energy consumption so as to achieve comprehensive and effective utilization of biogas energy.

摘要: 提出了一种沼气机热泵能源综合利用节能系统,并据此构建了系统实验平台,进行了系统性能实验.根据理论分析和实验数据研究了沼气消耗量、余热回收利用、制热系数COP及一次能源利用率PER随沼气机负荷率的变化趋势.结果表明:该节能系统具有较好的部分负荷特性,在仅考虑沼气机排烟余热回收利用的情况下,系统COP最高可达4.18,PER最高可达1.4.因此,空气源沼气机热泵节能系统明显提高了供热能力、降低了能耗,实现了沼气能源的综合有效利用.
