摘要
介绍了燃气发动机热泵系统的构成及其工作原理,说明燃气发动机热泵的使用可减少空调/供热的用电量,缓解由空调/供热引起的电力紧张状况,降低电网的峰谷差,同时可调节燃气消耗量的季节不均衡性,并有利于环境保护。根据空调/供热系统的不同方式,给出了比较这些系统能源利用率的统一指标-一次能源利用率,并利用一次能源利用率分析了六种供热系统的能源利用率,分析结果表明燃气发动机热泵的一次能源利用率最高,可节省能源。文章对燃气发动机热泵的性能进行了测试,一次能源利用率达到1.76。
The system and work principle of gas- engine heat pump （GHP） are introduced in this work.It shows that the electricity consumption for air conditioning/heating could be reduced, mitigate electricity intense conditions, and regulate seasonal gas consuption by using gas engine heat pump.Energetic efficiency evaluation of six heating system is presented, where primary energy rate （PER） is used. The comparison results show that the gas - engine heat pump has the highest primary energy ratio and save energy consumption. The performance of GHP was tested in this paper. PER of GHP is about 1.76.
