Energy-Saving using New Air Handling Unit for High Internal Moisture Gain Applications
This study investigates the feasibility of using two aluminum foam desiccant packed heat exchangers (DPHE) installed inside an air handling unit (AHU) to supply dehumidified air to a closed swimming pool area located in Alexandria, Egypt. The heat exchanger is a simplification to an open flow cycle mathematical model in order to simulate the downstream air temperature and humidity ratio. Previous experimental work was used to validate the mathematical model which shows a good agreement between the numerical model and experimental results at the same inlet conditions and geometric parameters. A parametric study is done to investigate the appropriate cycle time needed to achieve the required supply conditions.
