摘要
提出了一种采用空气源和电加热复合的辅助能源形式的复合源水环热泵空调系统,并对不同室外温度下建筑不同内外区冷热负荷比的情况下该复合源水环热泵空调系统的性能进行了分析与研究。将复合热泵循环系统能耗和使用锅炉的传统水环热泵空调系统的能耗进行了比较,体现出复合系统具有较高的能效比。分别计算了不同室外温度下建筑内外区冷热负荷比为2∶8和4∶6时,不同循环水温对复合热泵循环系统的能耗的影响,得出了最佳循环水温的范围。
A hybrid heat source water- loop heat pump system is proposed, which uses air source and electricity source as its auxiliary energy source. Considering different cold and hot load ratio between inside and periphery of buildings, Coefficient of the system performance is calculated under the conditions of different ambient temperatures. Compared with the energy consumption of traditional water-loop heat pump using boiler, the results show that the performance coefficient of the system of hybrid heat pump is higher. Effects of different Water temperatures on energy consumption of hybrid heat pump system are analyzed when cold and hot load ratio between inside and periphery of buildings are 2：8 and 4：6, and the optimal range of water temperatures is obtained.
