Abstract

This study evaluates the energetic performance of a combined evaporative cooling system (CECS) implemented in a residential building under the climatic conditions of Karshi city. The system performance was analyzed based on cooling load assessment and airflow balance calculations for a representative summer day. The experimental results showed a maximum cooling load of 9.42 , with system cooling effectiveness reaching 61.35% and a COP of up to 2.44. Seasonal analysis indicated electricity savings of 1368 , equivalent to 168.3 of standard fuel, over a 152-day cooling period. The findings confirm the energy-saving potential of CECS in hot and dry climates.
