چکیده

Steady-state energy and exergy evaluation are performed on two designs of a hybrid building integrated photovoltaic thermal (BPT) unit and a thermal wheel (SRX). The working principles of these designs in summer are similar such that the warm outside air is precooled by exchanging heat with air coming out of the building in SRX and then enters the building. Also, other outlet air from SRX passes through the BPT unit and cools PV modules, boosting their efficiency. The working principle of the design A in winter are that the outside air is preheated by receiving heat from the building exhaust air in SRX and then preheated again by passing through the BPT system. The design B works in the same way in winter, with the air passing through the BPT system first and then the SRX. The outcomes revealed that the annual total rate of thermal energy, electrical energy and thermal exergy outputs of the design A are 23183.4 kW h, 5994 kW h, 261.6 kW h, respectively, while these values for the design B are respectively 22785.2 kW h, 6030. 6 kW h and 243 kW h. In addition, it was found that the overall energy/exergy performance of design A is better/worse than design B.
