In this paper, the compound parabolic concentrator (CPC), phase change regenerative heat core and vacuum tube type solar air collector are combined to investigate a CPC regenerative heat solar air collector that combines the functions of regenerative heat and heat concentration. The whole-to-part approach is used to illustrate the construction of this new collector. At the same time, the thermal performance of the new collector is compared with other conventional collectors in terms of collector temperature and operating time through the construction of an experimental system test rig. From the results it is concluded that the CPC regenerative heat solar air collector not only increases the collector temperature but also extends the operating time compared to conventional solar thermal collectors. It achieves a maximum output temperature of 110.8°C. It can operate for approximately 3h longer during the day. The results of this study provide a meaningful reference for the further development of a multi-technology combined solar thermal collector.
