Keywords:

This study examines a combined evaporative cooling system (CECS) integrated with a photovoltaic module for improving indoor comfort in residential buildings. An experimental house equipped with the CECS was tested under real climatic conditions. Solar radiation intensity on August 12, 2024, ranged from 243.8 to 926.2 W/m², while the indoor air temperature varied between 27-40℃. The total thermal load of the experimental house was 10.47 kW, of which 19.73% was transmitted through walls, 14.63% through the ceiling, 37.77% due to solar radiation and windows, and 27.87% due to infiltration. Results indicated that solar radiation constitutes the largest share of the thermal load. The findings confirm that applying CECS with solar energy can reduce cooling energy demand and enhance indoor thermal comfort.
