摘　　要：为建立空气源热泵热水器COP随室外环境温度和水箱温度变化的动态模型,先测定了某一空气源热泵热水器随环境温度和水温变化的COP,引入了卡诺因子,得出了COP的拟合公式,并与测试数据进行了对比,对比表明COP的拟合公式精确度较高,能够满足实际工程应用需要。同时,为使该拟合公式对不同性能的空气源热泵热水器具有普适性,在上述公式的基础上引入COP修正系数,得出了适合不同性能空气源热泵热水器COP的拟合公式,经实验对比,表明该公式也能较好的满足实际工程应用需要。To establish the dynamic model in which the COP of an air source heat pump water heater varying with the outdoor ambient temperature and tank temperature, the COP of an air source heat pump water heater varying with the ambient temperature and tank temperature was tested first. The Carnot factor was introduced to draw a fitting formula of COP, which was compared with the test data. The comparison shows that the precision of the fitting formula of COP is fairly high, which can satisfy the requirements of engineering applications. Meanwhile, in order to make this fitting formula universally applicable to air source heat pump water heaters of different performance, a COP correction factor was introduced on the basis of the above-mentioned formula and a fitting formula of air source heat pump water heater of difference performance was drawn. Validation experiments show that the formula can meet the practical application of engineering.
