Publication number: 20240085047Abstract: A system includes a controller, a heating, ventilation, and air conditioning (HVAC) unit, first and second dampers, and first and second pressure sensors. The first damper is positioned at a first air duct that supplies air from an exterior of a premises. The second damper is positioned at a second air duct that supplies air from an interior of the premises. The first pressure sensor is configured to detect an air pressure exterior to the premises. The second pressure sensor is configured to detect an air pressure within the premises. The controller is configured to receive the detected exterior air pressure and the detected interior air pressure, and the controller is configured to change the air pressure within the premises by adjusting at least one of the first damper and the second damper based on the detected exterior and interior air pressures.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Inventors: James T.

Publication number: 20180351181Abstract: Energy storage and conversion systems are, formed when tightly integrated components including thermochemical storage subsystem with a concentration cell to provide very high capacity and high energy density systems. Systems taught here include the unique combination of a thermochemical energy storage module in close thermal communication with a direct energy converter in the form of a concentration cell. A closed-loop thermochemical module receives heat input at a receiving port to drive a reversible chemical reaction. The end-to-end system achieves an ‘on-demand’ functionality because the reagents of said chemical reaction may be safely stored for long periods of time without detrimental effect. When these reagents are again reunited, they produce heat that may be transmitted to the direct energy converter arranged to convert so received heat directly into an electric output suitable for doing work on an external system.Type: ApplicationFiled: May 30, 2017Publication date: December 6, 2018Inventors: John Read, Daniel Sweeney
