“…The cooling system consists of two aluminum plates (cold surfaces), measuring 300 mm × 300 mm × 20 mm, through which seven 1 2 -inch copper tubes pass on each plate, as shown in Figure 3. Two K-type thermocouples (T5-T8) are placed on each cold plate to obtain temperature data during the test.…”

“…vs. 1 T is a straight line with slope −Ea/Ru and ordinate at the origin equal to ln AR u βE a , which allows us to clear the values of Ea and A. To determine the reaction model, the "master plots" graphs were used, which is the method recommended by the International Confederation for Thermal Analysis and Calorimetry (ICTAC) [48,49].…”

“…Global warming has become one of the greatest challenges facing humans in modern times, causing serious problems such as heat waves, drinking water shortages, and the spread of disease [1]. This phenomenon is mostly caused by the increase in the concentration of greenhouse gases in the atmosphere due to the use of fossil fuels to satisfy the growing demand for energy, which is, in turn, driven by population growth, the increase in the number of vehicles, and the development of new information technologies, among other reasons.…”

Fique as a Sustainable Material and Thermal Insulation for Buildings: Study of Its Decomposition and Thermal Conductivity

2021

View full text Add to dashboard Cite

Buildings consume a large amount of energy during all stages of their life cycle. One of the most efficient ways to reduce their consumption is to use thermal insulation materials; however, these generally have negative effects on the environment and human health. Bio-insulations are presented as a good alternative solution to this problem, thus motivating the study of the properties of natural or recycled materials that could reduce energy consumption in buildings. Fique is a very important crop in Colombia. In order to contribute to our knowledge of the properties of its fibers as a thermal insulator, the measurement of its thermal conductivity is reported herein, employing equipment designed according to the ASTM C 177 standard and a kinetic study of its thermal decomposition from thermogravimetric data through the Coats–Redfern model-fitting method.
