广东地区太阳能-空气源热泵复合系统供暖供生活热水实验研究

构建了一种太阳能-空气源热泵复合供热系统,在广东地区冬季的晴天和全阴天进行供暖供生活热水实验测试。针对办公建筑供暖供生活热水需求,定时间段供生活热水同时进行供暖实验。实验结果表明:晴天热泵相较于全阴天工况节电1.16 kW·h,供热效果优于全阴天工况,太阳能-空气源热泵复合供热性能相较于单独的空气源热泵更有显著优势;太阳能-空气源热泵复合系统供暖供生活热水期间,复合系统COP_(sys)平均值为4.71、波动范围在4.20～5.38,空气源热泵系统COP_(hp)平均值为4.60、波动范围在4.08～5.10。

Experimental Study On Heating and Domestic Hot Water System of Solar Air-Source Heat Pump in Guangdong

A solar air-source heat pump heating system was developed , which tests in sunny and all cloudy day in Guangdong during the winter. According to the demand for heating and domestic hot water in office buildings, heating experiments are conducted when seting the time period for domestic hot water. The experimental results show that compare with all cloudy conditions, sunny saves electricity for about 1.16 kW·h, the heating effect is better than that of overcast conditions. Compared with single air source heat pump, the performance of solar air source heat pump composite heating system is more obvious; overall experimental time, the average COPsys of composite system is 4.71 and fluctuation range is 4.20-5.38, the average COPhp of air source heat pump system is 4.60 and fluctuation range is 4.08-5.10.
