Thermal energy storage operates based on two principles: sensible heat results in a change in temperature*. An identifying characteristic of sensible heat is the flow of heat from hot to cold by means of conduction, convection, or radiation.*
Thermal energy storage processes involve the storage of energy in one or more forms of internal, kinetic, potential and chemical; transformation between these energy forms; and transfer of energy. Thermodynamics is a science that deals with storage, transformation and transfer of energy and is therefore fundamental to thermal energy storage.
Thermal energy storage (TES) systems store heat or cold for later use and are classified into sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage systems raise the temperature of a material to store heat. Latent heat storage systems use PCMs to store heat through melting or solidifying.
Energy stored as sensible heat in materials. Thermal energy can be stored as sensible heat in a material by raising its temperature. The heat or energy storage can be calculated as Heat is stored in 2 m3 granite by heating it from 20 oC to 40 oC. The denisty of granite is 2400 kg/m3 and the specific heat of granite is 790 J/kgoC.
The thermal heat energy stored in the granite can be calculated as The heat required to to heat 1 pound of water by 1 degree Fahrenheit when specific heat of water is 1.0 Btu/lboF can be calculated as q = (1 lb) (1.0 Btu/lboF) (1 oF) = 1 Btu This calculator can be used to calculate amount of thermal energy stored in a substance.
Heat storage in separate TES modules usually requires active components (fans or pumps) and control systems to transport stored energy to the occupant space. Heat storage tanks, various types of heat exchanges, solar collectors, air ducts, and indoor heating bodies can be considered elements of an active system.
