Exergy efficiency and optimum operation of solar collectors

Abstract

Efficiency and optimum operation of flat-plate solar collectors are investigated in terms of exergy delivery of the collector. Various exergy efficiencies are defined and output exergy efficiency is used to determine the optimum flow rate of a typical collector allowing for the pressure drop in tubes. The operation of a collector is investigated for optimum flow rate and various constant inlet temperatures using the output exergy efficiency and thermal efficiency together.
