Abstract :
This paper presents a theoretical analysis of desiccant cooling system based on second law analysis for the
environment condition of Kurukshetra, Haryana, India. Desiccant cooling system worked on ventilation and recir-culation mode. Renewable energy and low grade or waste energy can be used in the system. In this analysis, coef-ficient of performance (COP) is to be calculated in both ventilation and recirculation mode and found the best mode for the system according to environment condition. A very few studies have done on the second law aspects of these system. The reversible COP depends on the operating parameters and the analysis is based on certain op-erating conditions for the desiccant dehumidifier. The thermal and reversible COPs of an open desiccant cooling system depend on operating conditions of the system. A second law analysis is performed and reversible COPs are 2.26 and 2.56 in ventilation and recirculation mode respectively at ambient condition for month of May 43.3?C and 20%RH of Kurukshetra, Haryana. The results of the analysis provide an upper limit for system.
