MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202521053889 A) filed by Indian Institute Of Technology, Maharashtra, on June 4, 2025, for 'heat-driven membrane heat pump module for indoor air dehumidification and cooling.'
Inventor(s) include Ketan Vijay Kalley; Kashish Kumar; and Gurubalan Annadurai.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A heat-driven membrane heat pump module for indoor air dehumidification and cooling is disclosed. The module comprises a membrane dehumidifier (1), a cooling coil (2), a membrane evaporative cooler (5), an ejector (7), a condenser (8), an expansion valve (9), a four-way valve (10), and a boiler (11). Incoming air is dehumidified across the membrane dehumidifier (1) and cooled by the cooling coil (2). The ejector (7), driven by motive steam from the boiler (11), maintains sub-atmospheric pressure on the permeate sides of the membrane dehumidifier (1) and the membrane evaporative cooler (5) via vapour suction pipes (6). Entrained vapour and motive steam condense in the condenser (8), producing liquid water that passes through the expansion valve (9) and is distributed by the four-way valve (10) to the cooling coil (2), the boiler (11), and the surroundings. The membrane evaporative cooler (5) recirculates cooled water to the cooling coil (2)."
