| Summary: | A desiccant air conditioning system is considered a capable alternative to a conventional air conditioning system because of its independent control of temperature, humidity and being eco-friendly. Also, to resolve the problem of more energy consumption for the restoration of a desiccant, structures comprising of desiccant can utilize thermal energy or complete waste heat to revive desiccant material. Therefore, this research work executes an experimental, optimization and comparative examination for conventional and desiccant air conditioning systems regenerated by two different modes, i.e. firstly using (Mode-I) complete waste heat from condenser and secondly using (Mode-II) rod (electric heater) heat for regeneration at different process air inlet temperatures, i.e. (28, 29.5, 31, 32.5, 34, 35.5 and 37 °C), at different process air inlet velocities, i.e. (1.5, 2.5, 3.5 and 4.5 m/s) and a fix (2.5 m/s) regeneration air inlet velocity. Thus, optimization of performance parameters, i.e. VCOP, ECOP, dehumidification effectiveness, moisture removal capacity (kg/hr), DCOP, regeneration effectiveness and regeneration rate (kg/hr), is identified for achieving maximum efficiency of conventional and desiccant air conditioning systems under the above operating conditions.
