ABSTRACT
The increasing ambient temperature and the growing demand for energy-efficient
cooling systems have encouraged the development of direct evaporative cooling
technology as an environmentally friendly alternative. The performance of this
system is highly influenced by the type of cooling pad material used. Although
honeycomb cooling pads are widely used due to their good performance, their
relatively high cost and limited service life necessitate the exploration of more
economical and sustainable alternative materials. This study aims to analyze the
performance of a direct evaporative cooler using coconut coir fiber and palm fiber
(ijuk) cooling pads and compare them with a honeycomb cooling pad. Experiments
were conducted at three air velocity levels, namely 1.7 m/s, 2.1 m/s, and 2.4 m/s.
The observed performance parameters included dry-bulb temperature reduction
(ΔTd), saturation efficiency (ηs), relative humidity (Hr), cooling capacity (Qc), and
coefficient of performance (COP). The results showed that increasing air velocity
improved the performance of all cooling pad types. At an air velocity of 2.4 m/s, the
honeycomb cooling pad exhibited the best performance, with average values of ΔTd,
ηs, Hr, Qc, and COP of 1.7°C, 54.497%, 87.29%, 738.28 W, and 12.304,
respectively. The coconut coir fiber cooling pad demonstrated better overall
performance than the palm fiber cooling pad, achieving average values of ΔTd, ηs,
Hr, Qc, and COP of 1.438°C, 46.325%, 85.99%, 623.226 W, and 10.387,
respectively. Meanwhile, the palm fiber cooling pad showed the lowest overall
performance but produced the lowest average relative humidity value of 84.713%,
indicating a better ability to limit excessive increases in air humidity. Overall, the
honeycomb cooling pad provided the best cooling performance, while coconut coir
fiber and palm fiber showed significant potential as environmentally friendly
alternative cooling pad materials that utilize abundant local natural resources.
