AI Technical Summary

Benefits of technology

The invention is a system that stores and releases heat. It uses phase change material (PCM) to store heat, and a separate fluid to absorb the heat from the PCM and use it outside of the system. The PCM is charged by an external heat source. The operation fluid is the fluid that interacts with the PCM and is heated by the PCM. The system is well-insulated to maximize the exchange of heat between the PCM and operation fluid. Overall, the invention allows for efficient storage and release of heat.

Problems solved by technology

Responsibly supplying energy needed for human society has arguably become the most complex, and controversial challenge facing us today.
The sun setting at night remains the most prevalent challenge for solar energy as a primary power source.
Similarly, many long existing heating systems operate at low efficiencies.
In between cycles, most conventional heating systems rapidly lose temperature to their surroundings, due to less than optimal insulation, and older, less efficient materials.
This puts a heavy tax on the heat source, which must bring the entire system back up to operating temperature at the start of each cycle.
These fundamental problems have led to widespread research into storage of thermal energy.
Air conditioning is only possible because of this latent heat phenomenon.
Sensible heat is far less efficient for thermal energy storage than latent heat, which may have 100 times the storage capacity of sensible heat.

Embodiment Construction

[0030]FIG. 1 shows the preferred embodiment of the invention, with a dual fluid heat exchanger system contained within vessel 500. Entry ports 101 and 301 and outlet ports 102 and 302 are shown extending out of vessel 500. The location of the entry and outlet ports can be anywhere on vessel 500.

[0031]As shown in FIGS. 2, 3 and 4, vessel 500 comprises a thermal insulating layer 501 surrounding an interior cavity wall 502. Insulation layer 501 can be a variety of different standard types of thermal insulation such as spray foam, fiber glass, vacuum and other similar materials known in the art. Interior cavity wall 502 provides a sealed barrier for cavity 400 within vessel 500. The cross sectional view in FIG. 3 shows a dual fluid heat exchanger assembly symmetrically centered within cavity 400. The dual fluid heat exchanger assembly is comprised of charging circuit 300 which contains charging fluid and operation circuit 100 which contains operation fluid. Charging circuit 300 extends ...

Abstract

An insulated vessel containing phase change material (PCM), with an elongated conduit through the PCM, the conduit having an inlet and outlet extending outside of the insulated vessel. The PCM absorbs and stores thermal energy originating from a heat source external to the insulated vessel. Operation fluid flowing through the conduit absorbs stored thermal energy from the PCM and can be utilized on demand. A second conduit may be provided to introduce thermal energy to charge the PCM.

Description

FIELD OF INVENTION[0001]This invention directly relates to the field of energy storage. The invention is a device used for increasing the efficiency and / or prolonging the operation of a fluid heating system. Such systems include but are not limited to water heating, space heating, boilers, and forced hot air systems.BACKGROUND[0002]Responsibly supplying energy needed for human society has arguably become the most complex, and controversial challenge facing us today. The sun setting at night remains the most prevalent challenge for solar energy as a primary power source. It is well known in the power industry that the highest demands for power usage are in the morning and evening, when people are leaving their homes for the day and returning home from work or school. Compounding the problem of high demand, these times are also when the sun's rays are at their weakest. This creates a need to supplement solar energy systems with some conventional carbon fuel based energy. Similarly, ma...
