Analytical examination of the performance of a novel heat recovery unit consisting of a thermal wheel and a building-integrated photovoltaic/thermal system with PCM

Introducing a heat recovery system that includes a thermal wheel and a building-integrated photovoltaic/thermal system with PCM and checking its monthly and annual performance are among the goals of this research. This system is able to transfer/absorb heat to/from the ambient air in order to bring its temperature to the design indoor temperature. Also, the electric power produced by the photovoltaic panels can also supply the required electrical load of the building. It was revealed that this system is able to supply 445.54 kWh of thermal load, 1214.43 kWh of electrical load of the building every year, which is equivalent to about 70% of the energy load of the building.
