High thermal inertia

WebJul 11, 2024 · The thermal inertia, or effusivity, can be considered as a measure of the ability of a material to exchange thermal energy with its surroundings, where the term "ability" refers not only to how much heat it is able to transfer, which is primarily due to its volumetric heat capacity, but also the rate at which it can transfer heat, which is … WebThe high volumetric heat capacity and thickness prevents thermal energy from reaching the inner surface. When temperatures fall at night, the walls re-radiate the thermal energy back into the night sky. In this application it is important for such walls to be massive to prevent heat transfer into the interior.

In the building environment, the thermal inertia of materials is used in different building design disciplines.

WebSummary Thermal inertia is a volume property of materials that describes its efficiency at changing temperature. It is a function of density, heat capacity, and thermal conductivity, but for most geological materials the dominant term is density: thus, rocks have a relatively high thermal inertia but soils have a lower thermal inertia. WebThe figure above shows the results of a computer model that tracks the temperature of these two cubes. One way to summarize this is to say that the higher the heat capacity, the greater the thermal inertia, which means …
