Abstract

Performance of solar-assisted hybrid air-conditioning liquid desiccant system in Beirut N. Ghaddarl, K. Ghali2 & A. ~ a j m ' I American University of Beirut, Faculty of Engineering and Architecture, Beirut 11 07 2020, Lebanon 2 Beirut Arab University, Faculty of Engineering, Beirut, Lebanon Abstract In this work a model of a solar-operated liquid desiccant system (using calcium Chloride) for air dehumidification is developed. The desiccant system model is integrated with a solar heat source for performance evaluation at a wide range of recorded ambient conditions for Beirut city. The desiccant system of the current study is part of a hybrid desiccant-vapor compression system for a high latent load application, namely a small restaurant with an estimated cooling load of 11.39 TR (40 kW), including reheat. The relevant parameters of the desiccant system are optimized at peak load, and it is found out that there is an important energy saving if the ratio of the air flow rate in the regenerator t
