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.
