Comparison on cooling efficiency of cooling pad materials for evaporative cooling system

Abstract


 
 
 
 This research aims to examine on cooling efficiency of different type natural based material as a cooling pad for evaporative cooling system. Efficiency of direct evaporative cooling system mostly depends on the cooling pad and hence, the material used in the cooling pad plays a very vital role. Here, two types of natural based materials (activated carbon foam and luffa pad) were selected to be used as cooling pad. Those materials pad are then fabricated to fit into the evaporative cooling setup. Temperature, and humidity are the most important data in this experimental analysis. The readings of these terms are taken for each type of cooling pad using data logger and also, the further calculations are done based on these readings. The material of the cooling pad and the air flow rate are varied to observe the effect on their cooling efficiency. From the analysis, the ACF cooling pad shows better cooling efficiency compared to that of luffa pad.
 
 
 

Effect of Utilization of Different Materials and Thicknesses Evaporative Cooling Pad On Cooling Efficiency in Greenhouses in Hot-Arid Regions

“…Sliced wood pads have more cooling efficiency and crop productivity under greenhouse conditions. Radhiyah et al (2018) tested Luffa and carbon foam as materials of evaporative cooling pads foam. A conducted by Khobragade & Kongre (2016) and Chopra & Kumar (2017) studied on wood-wool and khus-grass as evaporative cooling pads materials.…”

Enhancing predictive accuracy of inside temperature and humidity in an agricultural greenhouse using data-driven modeling with artificial neural networks

“…than the potential evapotranspiration. Arid desert climates get very little or no rain (Aziz et al, 2018). Under such circumstances, mitigating thermal stress and managing evapotranspiration are critical considerations.…”

“…So, providing the right growing conditions there is very hard. Research shows that people often use active cooling systems like misting and fan and pad ventilation to reduce heat in arid climates (Aziz et al, 2018). These systems, plus evaporative cooling and shading, can cut the greenhouse air temperature by up to 8°C.…”
