Abstract

In this study, the performance of the combined system of photovoltaic-heat pump (PV/T) and effects of a newly designed evaporator on the performance of the combined system were numerically investigated. The coefficient of performance (COP) value of the heat pump and electrical efficiency of the photovoltaic system were determined considering the studies carried out at the same resource temperature. ansys Fluent software was used in the numerical analysis. According to the results, the electrical efficiency increased as expected. The maximum electrical efficiency obtained for photovoltaic system was 2.5% higher than those without cooling systems and the COP of the heat pump system was determined to be 4.75 at its maximum. The maximum exergetic efficiency of the combined system was calculated to be 55.5% at 6 m/s of refrigerant velocity.
