Abstract

AbstractTo mitigate the deleterious effects of climate change, sustainable energy technologies need to be developed and widely adopted. This study analyzes the effect of the evaporator/condenser area ratio on performance for a direct expansion solar heat pump water heater system operating in Medellín, Colombia. For the analysis, a dynamic simulation of the system is carried out via a numerical approximation using Python with the Coolprop library. Results shows that the evaporator area is more relevant than condenser area for the system performance. Also, an increase in evaporator area results in a better system efficiency. An area ratio between evaporator and condenser above 10 deteriorates the system performance.
