Evaluation of cooling system’s design for rural development in upper Egypt

Abstract EN

This paper focuses on the practical investigation and field experimental analysis of in-service cooling systems.

The main goals are evaluating and optimizing energy consumption of the expected commonly used cooling systems in Upper Egypt.

Based on field experimental results, an extensive analysis was executed to evaluate the impact of energy consumptions of different cooling systems especially indirect and direct evaporative systems against traditional water and / or air-cooled direct expansion systems, and chilled water systems and simple multibank evaporative systems.

Investigations in Upper Egypt showed that the use of air-cooled cooling systems leads to a very low energy efficiency ratio, EER, and poor coefficient of performances.

While water-cooled cooling systems ranged from 25KW to 175KW in cooling capacity showed good practices but have higher initial and running costs, which are not anticipated for residential projects.

Evaporative systems, which have over 92 %, effectiveness’s could be used in limited situations, While, utilizing indirect evaporative system combined with direct enclosed fog system, IEDEF, could be more efficient and durable in Upper Egypt Climates.

The paper outspreads the detailed design of typical IEDEF cooling system based on pre-defined architectural approach for common buildings designs that meet both of culture and life styles of residential applications in Upper Egypt.
