摘　　要：以天然气内燃机分布式能源系统为例,进行了全工况特性试验及能耗分析,结果表明:消耗燃气的流量与功率呈线性关系,机组满负荷运行气耗为3.92 k Wh/Nm^3、燃气消耗率为0.25,溴化锂机组的COP随着功率的增加呈现先增加后减小的趋势,制冷量与功率成正比例关系。一次能源利用率随功率的增大而增大,满负荷时一次能源利用率为76.9%。在低负荷时,相对节能率出现负值,满负荷时,相对节能率为33.7%,与常规分供系统相比,CO_2减排率为46%。Distributed energy system with natural gas internal combustion engine as an example, the full process characteristic test and energy consumption analysis, the results show that the consumption of gas flow has a linear relation with power, full load operation of the gas consumption is 3.92 kWh/Nm3, gas consumption rate is 0.25, lithium bromide COP with the increase of the power of the unit showed a trend of decrease after the first increase, refrigerating capacity and power proportional relations. Primary energy utilization rate with the increase of power, energy efficiency is 76.9% at full capacity at a time. At low load, the relative energy saving rate is negative, at full capacity, the relative energy saving rate is 33.7%.
