Numerical investigation of influence of extent and position of a bypass on the performance of a single unit liquid desiccant based evaporative cooler / Raja Naveen Pamu, P. S. Kishore and Siva Subramanyam Mendu

Air-conditioning of buildings is more energy-consuming with widely used vapour compression refrigeration systems in hot and humid areas. Alternatively, evaporative cooling does not show much effect in sultry regions because of increased humidity despite the minimum energy consumption. Indirect evapo...
