Using thermal inertia for better comfort and heat savings

Thermal inertia is a term commonly used to describe the observed delays in a body's temperature response during heat transfers. The phenomenon exists because of a body's ability to both store and transport heat relative to it's environment. Since the configuration of system components and mix of heat transfer mechanisms (e.g. conduction/convection/radiation) varies substantially between instances, there is no generally applicable mathematical definition for thermal inertia. T… WebHigh thermal inertia leads to slowly evolving thermal transients; • Resilience to hotspots and coldspots due to natural convection; • No stored chemical energy (i.e., no exothermic reactions); • No stored mechanical energy (i.e., no high pressure, and large margin to … csrds.ca
