Innovative Thermal Panel Utilizing the Exothermic Reaction of Caustic Soda for Residential Heating

Description:

This invention presents a novel thermal panel that harnesses the heat generated from the exothermic reaction between caustic soda (sodium hydroxide, NaOH) and water to provide residential heating. The panel, sized to cover a wall of the house, slides on a rail, enabling it to be exposed outdoors for water evaporation and brought back indoors for heat generation.

Construction and Operation:

• The Panel: Constructed from either tempered, heat-resistant glass or acrylic encased within an additional layer of acrylic containing water, the panel houses anhydrous caustic soda (in powder or granule form).
• Filling and Emptying System: An automated valve supplies the panel with cold water when indoors, and a drainage system facilitates the removal of spent water after cooling.
• Heat Generation: Inside the house, cold water is added to the anhydrous caustic soda, triggering an exothermic reaction that yields a substantial amount of heat.
• Heat Transfer: The heat is transferred from the hot solution to the house's heating system via a heat exchanger.
• Evaporation and Regeneration: Once the solution has cooled and the outdoor temperature surpasses 4 degrees Celsius, the panel is exposed to sunlight to allow water evaporation, leaving behind anhydrous caustic soda, ready for another heating cycle.

Primary Chemical Reaction:

• Exothermic Dissolution: NaOH(s) + H2O(l) → Na+(aq) + OH-(aq) + heat

Advantages:

• Renewable Energy Source: Indirectly utilizes solar energy through water evaporation and the heat generated by the chemical reaction.
• Low Operating Costs: The caustic soda is not consumed; only the evaporated water needs replenishing.
• High Thermal Efficiency: The reaction between caustic soda and water generates a significant amount of heat.
• Architectural Integration: The panel seamlessly integrates into the house's structure.

Safety Considerations:

• Caustic Soda Handling: Requires special precautions due to its corrosive nature.
• Panel Sealing: Crucial to prevent leakage of the caustic solution.
• Automated Control System: Recommended to ensure optimal and safe system operation, including temperature and water level control.

Conclusion:

This invention represents an ingenious and environmentally friendly approach to residential heating, utilizing the heat generated from the reaction between caustic soda and water, coupled with solar energy for water evaporation and system regeneration. By implementing this technology, we can reduce reliance on fossil fuels and contribute to a more sustainable future.
