An improved desiccant evaporative cooling system, parametric analysis, and system comparison

الملخص EN

This paper discusses a new cooling system that improves the performance of the ventilation cycle for the desiccant evaporative cooling system.

The present work is compared with previous studies under various conditions of ambient temperature and humidity ratios.

All systems are developed and tested by terms of TRNSYS software through which the validation process is also performed.

New components are used with different configurations to enhance the cooling of the supplied air.

The results of the validation model show a good agreement with the previously studied cycle with average errors of 1.8% and 0.74% for ambient temperature and humidity respectively.

The new system recorded higher performance characteristics over the previously studied systems also Exergy efficiency improved by 19.7% .
