太阳能、热泵、燃气联合供热系统能效测试

Energy Efficiency Test of Combined Heating System of Solar,Heat Pump and Gas

介绍太阳能集热器、空气源热泵和燃气壁挂炉联合供热系统的流程和控制策略。为了评价系统及各单元在不同运行工况下的性能,对系统进行测试,提出8种测试工况以及能效指标。在佛山地区搭建太阳能集热器-空气源热泵-燃气壁挂炉联合供热系统的实验台。由测试结果可知,系统在不同工况下,太阳能保证率最大为45.9%,空气源热泵的COP最大为5.13,燃气权重最大为0.57,系统综合能效比最大为2.62。

The process and control strategy of combined heating system of solar collector, air-sourceheat pump and wall-hung gas boiler are introduced. In order to evaluate the performance of the system and each unit under different operating conditions, the sys- tem has been tested, and eight test conditions and en- ergy efficiency indicators are proposed. The experi- mental platform for the combined heating system of so- lar collectors, air-source heat pump and wall-hung gas boiler is built in Foshan area. According to the test re- suits, the maximum solar energy guarantee rate is 45.9% , the maximum COP of air-source heat pump is 5.13, the maximum weight of gas is 0.57, and the maximum comprehensive energy efficiency ratio of the system is 2.62 when the system operates under differ- ent operating conditions.
