摘　　要：通过空气源热泵和太阳能热水系统两个单元的独立实验得出空气源热泵辅助型太阳能热水系统整机COP随全天太阳辐照量以及平均环境温度变化的实验模型。利用该模型可将随机气象条件下得到的实验值转换成某一标准气象条件下的评价值,从而对产品性能进行准确评价。对两台不同型号样机进行的实验结果表明:该模型得到的评价值偏差小于3%,该评价方法可用于空气源热泵辅助型太阳能热水系统整机COP的评价。The COP value of the system under random meteorological conditions can not reflect the real performance accurately due to the change of weather conditions. the air source heat pump and solar hot water system were tested, respectively. The test model for COP of the air source heat pump assisted domestic solar hot water system changed with the amount of solar radiation and the mean environment temperature was presented. The model could transform the experimental value under random meteorological conditions to an evaluating value under a certain standard meteorological conditions. It could be conducive to evaluate the performance of the system accurately. Two heat pumps with different types were tested. The experimental results show that the deviation of the model is lower than 3%. It indicates that this model can be used to evaluate the COP of air source heat pump assisted domestic solar hot water systems.
