Thermodynamic Analysis Of Desiccant Evaporative Cooling Systems Defined For Ro-Ro Cargo Vessel
Öz
This study presents the results of thermodynamic feasibility of the new desiccant- evaporative- cooling system for an air conditioning application in ships. The desiccant- evaporative- cooling system is characterized by energy efficiency and low environmental impact. In this work, thermodynamic possibility to install desiccant cooling system (DCS) has been studied for a M/V ASSTAR Trabzon Ro-Ro cargo vessel, by using fraction of the heat rejected by existing on-board engine. The baseline system is incorporated a desiccant dehumidifier, a heat exchanger, an indirect evaporative cooler, and a direct evaporative cooler. The system offered sufficient sensible and latent cooling capacities for a wide range of climatic, while allowing in flux of outside air in excess of what is typically required for Ro-Ro cargo vessel. The present work aims at identifying the parameters of the system cycle and investigates their effect on the performance of the waste-heat driven cooling systems. And, the effect of different return air flow rates usage on the system performance is another aspect of the study. Two approaches for mixing of the return air and outside air are introduced; one is consists of two recirculation cycles, other one is a ventilation cycle, all of them have been examined and demonstrated. The maximum coefficient of performance (COP) of a waste-heat driven cooling cycles were determined by assuming that the cycles are totally reversible.
