摘要
介绍一种将相变储热材料和太阳平板空气集热器相结合的太阳能集热/储热系统(包括结构设计和试验测试),并对整个系统的储热效率和热损失进行了估算。结果显示,装置的储热效率可达23%,热效率达55%。而同样情况下的普通集热器的热效率仅为19%,远远小于前者。因此,该太阳能集热/储热系统可有效降低集热器的热损失,提高集热效率。
A flat-plate solar air collector/storage system integrated with phase change materials was developed. Its structure was designed and its functional properties were tested. The thermal storage efficiency and thermal loss of the system were calculated. Based on the experiment and calculation, the thermal storage efficiency of the device was 23%. The thermal efficiency of the collector/storage system and the regular collector were 55% and 19% respectively; the former is 36% greater than the later. It shows that the solar collector/storage system can reduce the thermal loss and increase the efficiency greatly.
