%X This work highlights the cooling potential of a desiccant evaporative cooling (DEC) cycle for an insulated greenhouse
with a surface area of 300 m2. DEC is assimilated in a closed loop that is comprised of several greenhouse components, including a flat plate collector, desiccant wheel, heat exchanger, and evaporative coolers. The system cools and dehumidifies the air without using conventional harmful refrigerants. We insert our experimental data in to a numerical
model based on a transient system simulation program and analyze the feasibility of the solar DEC system. Our results
show that the best performance of the system (coefficient of performance COPel = 14; COPth = 0.94) is obtained using 60°C regeneration temperature and a supply/regeneration flow ratio of 0.2. The system reduces inside temperature by 6°C in comparison to a conventional system, and the increased electricity permits an increase of cost for 25 years as viewing time.
