 Solar assisted, pre-cooled hybrid desiccant cooling system for PakistanA. Khalid, M. Mahmood, M. Asif and T. Muneer Renewable Energy, 2009, vol. 34, issue 1, 151-157 Abstract: This work presents results of experimental and simulation study of a solar assisted pre-cooled hybrid desiccant cooling (PHDCS) system for air conditioning applications in Pakistan. Tests were conducted on a gas fired pre-cooled hybrid desiccant cooling test rig for high humidity Karachi weather. Using measured data sets from the test rig, validation of TRYNSIS model of the same cooling system was undertaken. Four modes or configurations of the cooling system were simulated for Karachi and Lahore climatic conditions. Lahore simulation results demonstrated that better COPp can be achieved using indirect evaporative cooler for pre-cooling and direct evaporative cooler for post-cooling of air. Life cycle assessment of solar air collector was performed and energy and environmental payback periods were found to be equal to 1 and 1.5 years, respectively. An economic assessment of the solar collector revealed a payback period of about 14 years.
