MUMBAI, India, Aug. 24 -- Intellectual Property India has published a patent application (202514077277 A) filed by Hitachi Industrial Equipment Systems Co. , Ltd. on August 13, 2025, for Waste Heat Recovery System, Waste Heat Recovery Unit, And Waste Heat Recovery Method.
Inventors include Takehiro Matsuzaka; Masahiko Takano; and Yoshitaka Takeuchi.
The application for the patent was published on August 21, 2026, under issue no. 34/2026.
Abstract: A technique is provided that can prevent damage to a waste heat recovery heat exchanger. An air compressor includes cooling heat exchangers that perform heat exchange between cooling water and compressed air, and a cooling liquid pipe through which the cooling water flows. A waste heat recovery unit includes waste heat recovery heat exchangers that perform heat exchange between waste heat recovery water and compressed air, a waste heat recovery liquid pipe through which the waste heat recovery water flows, a waste heat recovery liquid inlet pipe and a waste heat recovery liquid outlet pipe that connect an auxiliary cooling facility and the waste heat recovery liquid pipe, flow path switching three-way valves that open and close the inlet and outlet pipes, and a temperature controller that controls the valves. When the temperature of the waste heat recovery water exceeds a threshold, the temperature controller opens the inlet and outlet pipes by controlling the three-way valves.
