摘要：

对已搭建的混合动力燃气热泵平台,进行冬季制热工况实验,分析其运行的经济性。以混合动力热泵系统的燃料消耗量、燃料消耗率、燃料转换率及余热回收量作为经济性研究的指标,对系统在低负荷、中等负荷、高负荷等工况下对系统性能进行了测试试验,并与常规燃气热泵运行特性进行对比分析。结果表明:在低负荷下,混合动力燃气热泵燃料转换效率比常规燃气热泵高16.7%,平均燃料转换效率约为0.195;高负荷下,负燃料转换效率比相同负荷下的常规燃气热泵高12.1%,平均燃料转换效率约为0.151。

Abstract:

Hybrid gas engine heat pump (HPGHP) combines hybrid-power technology with heat pump technology to increase the fuel efficiency of the system. Based on a hybrid gas engine heat pump platform, this paper performed experiments under the winter heating condition to analyze operating economy of the system. The outdoor dry bulb temperature was 7℃, the evaporating and condensing temperature was -5℃ and 46℃, respectively. The optimization curve control strategy was adopted to control the engine operating in the economical zone and distribute requiring power between the engine and battery. The fuel consumption flow, fuel consumption rate, fuel conversion rate and recovered wasted heat were indicators of economic research. The system performance was tested under low, medium and high load separately and compared with conventional gas heat pump (GHP). Analysis results show that under low load, the average fuel conversion efficiency of hybrid gas heat pump is about 0.195, 16.7% higher than that of GHP. In high load range, average fuel conversion efficiency of hybrid gas heat pump is about 0.151, 12.1% higher than that of GHP under the same load.
