A Novel investigation of building integrated photovoltaic thermal (BiPVT) system: A comparative study

Further, an attempt has been made to analyze the thermal load leveling (TLL) with respect to number of air changes (No) for both the systems. It has been observed here; that the thermal load leveling for both the systems breaks even at number of air changes less than four which implies that, for both the systems, thermal comfort is achieved when the number of air changes is less than four. Therefore, it can be well assumed that the optimum TLL may be achieved when it is lying between 3 and 4 number of air changes.
