混合动力燃气热泵空调系统的能量分析模型
Energy modeling for a hybrid power gas-engine-driven heat pump air conditioning system
摘要：
在分析燃气发动机和蓄电池的动态负荷特性基础上，建立了混合动力燃气热泵（HPGHP）空调系统的能量分布模型，并进行了计算。结果表明，压缩机需求部分负荷的概率分布和燃气发动机直接对压缩机输送的功率与压缩机总功率的比值对HPGHP系统动力系统的热效率影响较大；当这个比值高于某个临界值时，HPGHP系统动力系统的热效率比常规燃气热泵空调系统高。
Abstract：
Analysing the dynamic load characteristics of gas engine and batteries, establishes the energy-coupled mathematical model of the hybrid power gas-engine-driven heat pump (HPGHP) air conditioning system, and carries out related calculation. The results show that two factors—the probability distribution of compressor part load demand and the ratio of the power directly from the gas engine to the compressor to the total power output of the compressor—impact notably the thermal efficiency of the power system of HPGHP system, and that the thermal efficiency of the power system of HPGHP system is higher than that of the conventional GHP system in the condition that the power ratio is larger than a critical value.
