Cooling System By Evaporation Of Water In A Fibrous Wall PDF

The evaporative cooling system has been considered as an alternative to the conventional vapor compression air conditioning system, which offers a simple, low cost, low energy and environmentally friendly solution for building's cooling demand. The aim of the paper is to present a new type of evaporative cooling system, which uses less mechanical equipment than common evaporative coolers. This system uses a fibrous wall as a medium for water evaporation, in order to cool down the air temperature. The paper starts with the state of the art of the evaporative cooling system, continues with the description of the proposed system and formulation of the associated model. The evaluation of the performance of the system under different parameters will also be presented. A case study in this paper showed that the system was able to reduce the air temperature by 4°C at night in city of Bechar, Algeria, with the average air temperature of a week reduced by 2.3°C. The studies indicate that this system is interesting for application in hot and dry area.
