An Investigation of Optimal Clay Brick Properties for Evaporative Cooling
The overuse of electricity, which is an indispensable component of our daily lives, is causing the rapid depletion of fossil fuel resources and emission of greenhouse gasses to the atmosphere. It is known that 40% of the electricity consumption of households and industry is due to the use of cooling systems especially during summer conditions. The aim of this study is to develop a natural refrigeration technique that can save a substantial amount of energy. It is hypothesized that with the use of baked clay structures (referred to as ceramic), a natural evaporative cooling technique can be developed, by which the temperature of the surroundings can be dropped by 6 to 10 ℃. This assumption was tested with the help of models. The clay plates with grain sizes 0.700 and 0.250 mm, baked at different temperatures (750, 875, and 1000 ℃) were prepared and tested for vertical/horizontal capillarity and falling head permeability. Afterwards, their evaporative cooling effects were compared. Samples baked at 1000 ℃ and grain size 0.700 mm gave the largest drop in temperature (ΔT ~ 14 ℃ when the air temperatures were between 30 and 40 ℃ and humidity percentages were between 35–40%). Based on these results, 0.700 mm particle-sized clay tiles that were baked at 1000 ℃, which also demonstrated satisfactory levels of capillarity and permeability, were chosen as the structural material for the future prototype tests.
