Abstract

Increasing demand on freshwater resources is driving the growth of desalination systems worldwide. The energy demand for these systems is quite large and in many cases, is needed in areas with a high solar resource. In this paper, a hybrid reverse osmosis and humidification dehumidification system is analyzed for use with a concentrating photovoltaic/thermal solar collector that produces electricity and thermal energy. Results show that a hybrid HDH/RO system utilizing both thermal and electrical energy can produce 38% more freshwater at steady state conditions than by utilizing the entire solar collector output as electrical energy for powering a standalone RO system.
