“…These results showed that the ESN application positively increased the evaporative cooling efficiency. In studies conducted by researchers, Al-Sulaiman [12] selected palm fibers (stem), jute, and luffa as wet pads in evaporative cooling; as a comparison, they used a commonly used commercial wet pad. The study calculated the average cooling efficiencies to be 62.1% for jute, 55.1% for luffa fiber, 49.9% for the commonly used commercial pad, and 38.9% for palm fiber.…”

“…Conventional air conditioning systems using a vapor compression cycle are uneconomical due to high electricity consumption. Evaporative cooling by means of evaporative coolers is therefore one of the best and most economical solutions [12]. Spring-summer temperatures are typically high in the Mediterranean basin, making evaporative cooling systems necessary for a suitable growing environment [4,13].…”

The purpose of this study is to determine the performances of luffa and greenhouse shading netting (which can be used as alternatives to commercial cellulose pads, that are popular for cooling greenhouses), the contribution of external shading to the evaporative cooling performance, and the energy consumption of the direct evaporative cooler. In this experiment, eight different applications were evaluated: natural ventilation (NV), natural ventilation combined with external shading net (NV + ESN), cellulose pad (CP), cellulose pad combined with external shading net (CP + ESN), luffa pad (LP), luffa pad combined with external shading net (LP + ESN), shading net pad (SNP), and shading net pad combined with external shading net (SNP + ESN). The cooling efficiencies of CP, CP + ESN, LP, LP + ESN, SNP, and SNP + ESN were found to be 37.6%, 45.0%, 38.9%, 41.2%, 24.4%, 29.1%, respectively. Moreover, their cooling capacities were 2.6 kW, 3.0 kW, 2.8 kW, 3.0 kW, 1.7 kW, 2.0 kW, respectively. The system water consumption values were 2.9, 3.1, 2.8, 3.2, 2.4, 2.4 l h−1, respectively. The performance coefficients of the system were determined to be 10.2, 12.1, 11.3, 11.9, 6.6, 7.8. The system’s electricity consumption per unit area was 0.15 kWh m−2. As a result of the study, it was determined that commercially used cellulose pads have advantages over luffa and shading net materials. However, luffa pads can be a good alternative to cellulose pads, considering their local availability, initial cost, cooling efficiency, and capacity.
