摘　　要：为了提高空气源热泵空调系统运行性能,研究了一套采用变回水温度控制策略的空气源热泵机组的制冷性能。实验研究表明,变回水温度工况可满足室内冷负荷需求。与传统采用定12℃回水温度的空气源热泵空调系统相比,COP更高,耗电量更小,是一种高效节能的空气源热泵空调系统控制方法。此外,所建立的Dymola模型从理论上验证了实验结果,在此基础上模拟实际空调系统的能耗,模拟结果表明,COP由3.99提高至4.39,提高了10%。In order to enhance the operating performance of air source heat pump, the performance of air source heat pump （ASHP） system with the variable inlet water temperature strategy was experimentally studied. As field test shows, the condition of variable outlet water temperature could satisfy the indoor cooling demmand. Compared with traditional ASHP cooling system adopting fixed 12 ℃ inlet water temperature, this kind of system is proved to be with higher COP and lower power consumption, and therefore is an obvious energy saving system. In addition, the Dymola model was established to verify the experimental results, and the simulation of energy consumption of actual air conditioning system was conducted based on the model. The results indicated that COP would improve 10 percent from 3.99 to 4.39.
