Description

Thermal energy is the energy that derives from the temperature of matter. Thermal energy storage is defined as a technology that enables the transfer and storage of thermal energy, or energy from ice, water, or cold air. This method will be integrated into new technologies that complement energy solutions such as solar and hydroelectric power.

Heat is energy transmitted to or from a thermodynamic system by methods other than thermodynamic work or matter transfer in thermodynamics. Heat is a quantity transmitted across systems, not a property or "contained" within any one system. Internal energy and enthalpy, on the other hand, are attributes of a single system. Internal energy is a property of a system's state and can thus be understood without knowing how the energy got there. Heat and work are dependent on how an energy transfer occurred, whereas internal energy is a property of the system's state and can thus be understood without knowing how the energy got there.

The internal energy of an ideal gas, in which the molecules move independently between instantaneous collisions, is the sum of the gas's independent particles' kinetic energies, and it is this kinetic motion that is both the source and the effect of heat transfer across a system's boundary, according to a statistical mechanical account. The phrase "thermal energy" is effectively synonymous with "internal energy" for a gas that has no particle interactions other than instantaneous collisions. The product of Boltzmann's constant and absolute temperature is referred to as "thermal energy" in several statistical physics texts. The constituent particles, like as molecules or ions, interact strongly with one another in a material, especially in condensed matter, such as a liquid or a solid.

Thermal energy (either hot or cold water) is generated during periods of reduced demand or electricity use and is collected in a thermal storage tank, then extracted and distributed to the facility during peak periods. Hot or cold water enters the tank and exits through diffusers located at the top and bottom of the tank. Diffusers are designed to eliminate turbulence and allow tank water to be stratified with cooler water at the bottom and hotter water at the top. A narrow and sharp transitional layer of water forms between the warm and cold water areas.

During night time, the water is chilled with 25% ethylene glycol by a chiller. The solution circulates in the heat exchanger inside the ice bank, freezing 95% of the water surrounding the heat exchanger in the ice bank and 95% of the water around the heat exchanger in the tank. The water around the heat exchanger never leaves the tank. Ice is evenly formed in the ice bank tank by counter flow heat exchanger tubes. While the ice is being made, the water continues to flow freely, preventing damage to the tank. The ice bank tank takes 6 to 12 hours to fully charge. At peak times during the day, the glycol solution circulates through the ice storage tank to provide stored energy to the building to increase the cooling of the electric cooler. Cold glycol at a suitable temperature is delivered to the cooling coil in the air. The fan blows air over the coils to cool the occupant spaces. People feel iced out and never know that ice storage is used to save money on refrigeration costs

Thermal energy storage applications

Thermal energy storage applications can be applied in the following areas:

• In concentrating solar thermal systems, which provide usable energy even at night.

• Increased operational capacity and faster load changes in thermal power plants.

• Ensuring heat supply security from block-type thermal power plants and temporary separation of heat and electricity generation.

Recovery and use of heat in manufacturing that would otherwise be lost.

Thermal energy involves a range of activities, such as drying, cooking, heating, smoking, baking, cooling, and manufacturing. Some of the more common fuels are coal, natural gas, uranium (nuclear), diesel, biomass, and oil products. Most thermal plants are large industrial connections used to generate electricity.
