摘要
太阳辐射对热泵系统的室外空气换热器的热工性能有显著影响。提出了通过修正换热器传热系数以考虑太阳辐射作用的计算方法,设计出了热泵系统的实验装置并由实测数据进行了计算,得出了有与无太阳辐射时的传热系数之间的关系式。该方法不但可以提高热泵系统的热工性能模拟和能耗分析的准确性,而且对热泵系统及其室外空气换热器的设计与安装具有指导意义。
The influence of solar radiation on the heat-transfer performance of an outdoor air heat exchanger in a heat pump system is considerable. This paper brings up a correction of the heat-transfer coefficient of the heat exchanger and a function relationship between the heat transfer coefficient with solar radiation and that without it. The result of the calculation based on experimental data shows the heat transfer coefficient with solar radiation is 36% larger than that without of it. The correction presented may improve not only the heating performance simulation and the energy analysis of the heat pump system, but also the designing of the heat pump system and the outdoor air heat exchanger and their operation.
