MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202611047816 A) filed by Ziyad Siraji on April 15, 2026, for A Hybrid Energy-Efficient Cooling System Without Refrigerants Or Humidity Build-Up.
Inventor includes Ziyad Siraji.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present invention relates to a refrigerant-free, energy-efficient air cooling apparatus suitable for small-scale indoor applications. The apparatus comprises a multi-section housing including a middle cooling section having a plurality of hollow aluminium pipes through which room air flows. Water is sprinkled over the external surfaces of the aluminium pipes to enable indirect evaporative cooling, while humid air is expelled outside the enclosed space. The system operates without compressors or refrigerants and limits indoor humidity rise, providing a low-cost and sustainable cooling solution for residential and similar environments.
