Antonopoulos and Koronaki (1998) investigated the concept of effective thermal capacitance
, a useful concept for simplified modeling.
7) Second, the system has a high thermal capacitance
, so control sequences should avoid any requirements for rapid modulation.
As a consequence, when computer simulations of GCHP systems with a short time step are carried out, a suitable model of the borehole thermal capacitance
is necessary because it affects the heat carrier fluid temperature and, consequently, the consistent detailed prediction of the thermal behavior of the borehole field.
It is often possible to work with less of a temperature difference depending on the thermal capacitance
of the building materials.
R/(Pi x C)) R = Effective thermal resistance of chip in [degrees]C/W C = Effective thermal capacitance

There, on a very difficult site next to one of the main railway lines from London to Scotland, quite ordinary and easily available materials such as sand bags, straw bales, solar collectors and corrugated polycarbonate sheet were bravely used to make an experimental building with unusual thermal capacitance
and receptivity to ambient energy.
diss] is a clear sign that the thermal capacitance
is also a function of dissipated power.
2011) demonstrated progress toward experimentally determining the thermal capacitance
(product of mass and specific heat) of a 2 U (89 mm) server and highlighted, for the first time, the need for developing a compact server model for transient simulations.

Note that with the current wall thermal capacitance
and density, the wall surface temperatures remained low for a longer period while air temperature quickly reached 20[degrees]C.
