MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511116107 A) filed by National Institute Of Technology Delhi; and Dr. Manoj Kumar Nayak, New Delhi, on Nov. 24, 2025, for 'multi-mode water dispenser device.'
Inventor(s) include Dr. Manoj Kumar Nayak; Dr. Vinay Shankar Pandey; Prof. Ajay K. Sharma; Dr. Divya Punia; and Atish Gochhayat.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "Disclosed herein is a multi-mode water dispenser device that can dispense hot or cold or normal water at point of use as per user requirement very promptly in energy saving manner. The device runs without any heating element, condenser, heat exchanger or fan. The device comprises a water supply unit (100), two (first, second) water chambers (200, 300), a refrigerant filled compressor (400), and a refrigerant recirculating copper tubular path (500). The compressor (400) is operatively connected between the chambers (200, 300) through the copper tubular path (500). The tubular path (500) forms a first spiral coil tube (502) inside the first water chamber (200), a second spiral coil tube (504) inside the second water chamber (300), and a capillary coil tube (506) outside the chambers (200, 300). The water supply unit (100) supplies normal water into the chamber (200, 300). The first spiral coil tube (502) is adapted to receive compressed hot refrigerant from the compressor (400), and release heat in water contained in the first water chamber (200) making the water hot (HW) therein. The second spiral coil tube (504) is adapted to receive the refrigerant from the first spiral coil tube (502) after being expanded and cooled by the capillary coil tube (506), and absorbs heat from water contained in the second water chamber (300) making the water cold therein."
