Abstract
The impact of ambient pressure on the performance of the ventilation cycle desiccant cooling system and its components was studied using computer simulations. The impact of ambient pressure depended on whether the system was designed for fixed-mass flow rate or fixed volume flow rate operation. As ambient pressure decreased from 1.0 to 0.8 atm, the system thermal coefficient of performanceincreased by 8% for both fixed-mass and fixed-volume flow rate, the cooling capacity of the system (in kW) was decreased by 14% for the fixed-volume flow rate system and increased by 7% for the fixed-mass flow rate system, the electric power requirements for the system with fixed-volume flow rate did not change, and the electric power requirement for the fixed-mass flow rate system increased by44%. The overall coefficient of performance increased up to 5% for the fixed-volume flow rate system, and decreased up to 4% for the fixed-mass flow rate system.
