Principle of energy storage temperature control system
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.

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.
Thermal energy storage processes often involve changes in temperature, volume and/or pressure. The relationship between these properties is therefore important for the design and operation of thermal energy storage systems. This subsection briefly discusses the pressure-volume-temperature (PVT) behaviour.
Thermal energy storage (TES) systems can store heat or cold to be used later, under varying conditions such as temperature, place or power. TES systems are divided in three types: sensible heat, latent heat, and thermochemical. Clues for each TES system are presented in this chapter and requirements for each technology and application are given.

6 FAQs about [Principle of energy storage temperature control system]
How is thermal energy stored?
Thermal energy can generally be stored in two ways: sensible heat storage and latent heat storage. It is also possible to store thermal energy in a combination of sensible and latent, which is called hybrid thermal energy storage. Figure 2.8 shows the branch of thermal energy storage methods.
How is thermal energy storage performed based on heat changes?
As thermal energy storage is performed based on the heat changes in an energy storage medium, first, we need to define the branch of heat. There are two types of heat change in a material: sensible and latent heat. When energy is released from a material, the temperature of that material decreases.
What are the operational principles of thermal energy storage systems?
The operational principles of thermal energy storage systems are identical as other forms of energy storage methods, as mentioned earlier. A typical thermal energy storage system consists of three sequential processes: charging, storing, and discharging periods.
What are thermal energy storage methods?
Thermal energy storage methods can be applied to many sectors and applications. It is possible to use thermal energy storage methods for heating and cooling purposes in buildings and industrial applications and power generation. When the final use of heat storage systems is heating or cooling, their integration will be more effective.
What is a thermal energy storage system?
A thermal energy storage system can be regarded as a control volume or an open system during charge and discharge processes if the storage material also acts as a heat transfer fluid. A phase refers to a quantity of matter that is homogeneous throughout. There are three phases in nature: gas, liquid and solid.
How energy is stored in sensible thermal energy storage systems?
Energy is stored in sensible thermal energy storage systems by altering the temperature of a storage medium, such as water, air, oil, rock beds, bricks, concrete, sand, or soil. Storage media can be made of one or more materials. It depends on the final and initial temperature difference, mass and specific heat of the storage medium.
