Evaporative system for water and beverage refrigeration in hot countries

Abstract

The present study proposes an evaporative refrigerating system used to keep water or other beverages cool in hot arid regions. The system uses a flow of air that flows around a water container, which is wrapped in a wet fabric. The air before being introduced could be dehumidified and cooled to capture more quantity of water vapour. A mathematical model has been developed to describe the system behaviour and the model has been solved numerically. The effects of many parameters on the system performance have been investigated. Results showed that the suurounding pressure around the tank has a significant effect. A cross-over value of mass flowrate at which the effect of ambient temperature changes is found. The results obtained are found to be consistent with the available literature data.
