Changes in Temperature in a Material Kapok-plaster Sample in Dynamic Frequential Regime

Influence of Excitation Period on Thermal Transfer of Tow-Plaster Thermal Insulation Plate Attached to Wall: Application to Cold Room

“…A cold room ( Figure 1) is a special room equipped with a refrigeration machine [6] which keeps the temperature and relative humidity [7] of the air at constant values.It consists of four side walls, a ceiling and a low floor. The particularity of these local insulators is based on the type of thermal insulation [8,9] used which is a determining factor for maintaining a low temperature at a reasonable energy cost.The insulation in question is subjected to external climatic stresses [10] as shown in Figure 1 (convection, radiation, etc.). Figure 2 is a section on one of the side walls of the cold room showing the composition of the materials and their different thermophysical parameters.…”

Characterization Phenomena of Thermal Transfer Through an Insulating Material Kapok-plaster Starting from Dynamic Impedance Method

“…A 1 and A 2 coefficients depend on thermal parameters and boundary conditions Eq. ( 6) and ( 7) imposed (Boukar et al, 2014, Ould Brahim et al, 2011b:…”

“…By studying thermal impedance (Boukar et al, 2014), considering his behavior limited to low and high pulse, we establish a relationship between electrical and thermal quantities.…”
