“…During this process, water gets latent heat of evaporation and evaporates while air absorbs sensible heat and decreases in dry bulb temperature. This cooling process is more effective in regions with a dry and hot weather condition [3,5]. To date, Aspen pad made from wood shavings of propulus tremuloides and Celdek (Trade name) paper pad are the commercially available high-performance pad on our market.…”

Evaporative coolers are technologies highly used as a source of thermal comfort in terms of fresh air provider in areas where weather conditions are harsh and people living standard goes from medium to low earnings. This technology being environmentally friendly still requires a certain minimum maintenance, mostly the change of pads. This paper presents the performance of a cost-effective cooling pad made from the fibers of hyphanene thebaica (wood wool) as an alternative pad to the commercial ones rendering this technology more accessible and affordable for all social classes. The experiment was done in an insulated duct whereby thermodynamic parameters of locally made pad such as temperature, pressure, relative humidity and velocity, were recorded, and effect of physical properties on performances were analyzed. Compared to the commercial pad, the proposed local pad presented the lowest minimum outlet dry bulb temperature (20.00oC), a saturation efficiency of 78.80% with the highest cooling capacity of 0.1867 kW, the highest heat transfer coefficient of 7.3497 kW/m2 oC, the best cost-to-efficiency ratio (CER) and coefficient of performance (COP). By studying and improving the pads thermophysical characteristics, performance could be improved opening ways towards industrial production of such pads for a sustainable development.

“…The synthesis and characterization of electroactive polymers has become an important area of materials science in recent years. Polyheterocycles such as polypyrroles and polythiophenes have received significant attention due to their high electrical conductivities and relative stabilities. , The thiophene family of polymers has been conventionally synthesized by either chemical − or electrochemical ,− routes; but more recently attempts have been made to employ nonisothermal plasma techniques because of the potential benefits of dry application to any substrate geometry together with minimal environmental waste. − Plasma polymerization is based upon the activation and reaction of a precursor molecule by an electrical discharge . Ions, radicals, electrons, metastables, and photons can all participate in the deposition of polymeric material over all surfaces in contact with the plasma.…”
