Numerical and experimental work to assess dynamic advanced exergy performance of an on-grid solar photovoltaic-air source heat pump-battery system

In the near future, renewable energy powered air conditioning systems will play an important role in the building sector. In this study, a solar photovoltaic powered air source heat pump with a battery system was modeled and numerically simulated using Transient System Simulation Tool. The experimental studies were also carried out to validate the developed model. The novelty concerns to integrate conventional and advanced exergy analyses into the numerical model to annually determine the exergy destructions with main sources (exogenous, endogenous, unavoidable, avoidable and their combination) at a component level.
