Abstract
This paper evaluates the technical feasibility and performance of a solar-driven Dunkle cycle desiccant cooling system for a residential building under the climatic conditions of Tripoli. The study investigates the influence of several operational parameters such as reactivation temperature and the effectiveness of heat exchangers 1 and 2 on the overall system performance.
A computer program was developed based on mathematical models representing the system components to calculate the coefficient of performance (COP) and the solar energy contribution during the cooling season (June to September).
The results indicate that the solar Dunkle cycle desiccant cooling system can effectively operate under the climatic conditions of Tripoli, achieving an average COP of 0.98 throughout the cooling season. The analysis also reveals that the system performance is significantly affected by both the reactivation temperature and the heat exchanger effectiveness.
