Energy storage cooling method

What are thermal energy storage methods?

Thermal energy storage (TES) methods store thermal energy for later use. One of the earliest and well-known applications of TES is storing solar energy during the daytime for use at nighttime, enabling continuous usage throughout the day.

How can energy be stored in a TES system?

In TES systems, energy can be stored via changing the internal energy of the storage medium as: 1. 2. 3. Mature TES techniques that are preferred for heating or cooling applications are sensible heat storage and latent heat storage.

How does a heat storage system work?

A heat storage system works by storing energy during off-peak hours and releasing it when there is a heating demand. This is achieved by circulating air via a fan to meet the heating load of a house. The stored energy is then discharged to fulfill the heating requirements.

How is sensible heat storage achieved?

Sensible heat storage is achieved by increasing or decreasing the temperature of the storage medium. A typical cycle of sensible heat thermal energy storage (SHTES) system involves sensible heating and cooling processes.

What happens during the cooling process in SHTES?

The heating (or cooling) process increases (or reduces the enthalpy of the storage medium). A typical cycle of sensible heat thermal energy storage (SHTES) system involves sensible heating and cooling processes as given in Fig. 3.3.

What is the main purpose of thermal energy storage?

Thermal energy storage (TES) is a key technology in reducing the mismatch between energy supply and demand for thermal systems. Thermal energy storage is essential for using conventional energy systems in a manner that is sustainable, efficient, economical, and environmentally friendly.
