The system was comprised of a solar air collector, a parabolic trough collector, and a heat pump system. The performance of the fluidized bed drying system was assessed by conducting energy and exergy analyses. This fluidized bed dryer was used to investigate the drying kinetics of mint leaves. The temperatures of the air used for drying by the solar energy system and the heat pump system were 45 and 50 degrees C, respectively. The energy and exergy efficiencies of the system were found to be 50 and 26%, respectively. The heating coefficient of performance (HCOP) was suggested as a new performance parameter of a solar energy system. The heat pump system had a coefficient of performance (COP) value of five. In other words, the heating coefficient of performance of this solar energy system was 10. (C) 2016 Elsevier Ltd.
