A Novel Concept of Solar Photovoltaic-Thermal, Heat Pipe and Heat Pump Hybrid System using AiO203 Nanofluid

A numerical prediction of a novel hybrid system concept to enhance thermal energy efficiency and reduce carbon print composed of photovoltaic-thermal solar panels, heat pipe, and heat pump is presented hereby. This model is intended to assess the performance and energy conversion process of the hybrid system as well as the individual efficiencies and integral system efficiency of this process to produce useful thermal energy for a variety of applications and electricity. A two dimensional heat transfer and fluid flow dynamic model was developed and presented to describe the behavior of the different components of the hybrid system under different solar irradiance conditions, AiO203 Nanofluid, and different refrigerants. The model is based on dynamic mass and energy equations coupled with the heat transfer formulas and thermodynamic properties of nanofluid, as well as refrigerant mixtures. Finally, the presented model has been validated, and its prediction is fairly compared with available data.
