Abstract: A solar energy-based trigeneration system is proposed and analysed energetically and exergetically. Results show that increasing heliostat field area and solar flux decreases the energetic efficiency of trigeneration, while its exergetic efficiency is increased. Increasing area from 8,000 m² to 50,000 m², results in enhancement of electricity, refrigeration, and hydrogen production from 287.6 kW to 5,375 kW, from 950 kW to 13,430 kW, from 3.16 kg/hr to 22.63 kg/hr, respectively. Promotion of solar flux from 400 W/m² to 1,200 W/m² provides enhancement in the energetic and exergetic efficiencies of solar field from 57.6% to 62.4% and from 39.12% to 42.16%, respectively.
