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。
Through the independent experiment of air source heat pump and solar hot water system, the experimental model of the COP of the air source heat pump assisted solar hot water system with the change of the whole day solar radiation and the average ambient temperature is obtained. The model can be used to convert the experimental value obtained under random weather conditions into the evaluation value under a certain standard meteorological condition so that the product performance can be accurately evaluated. Experimental results on two prototypes of different models show that the deviation of the evaluation value obtained by this model is less than 3%. This evaluation method can be used to evaluate the COP of the air-source heat pump assisted solar hot water system.
