Patent number: 12326300Abstract: A system includes a heat exchanger that includes a relatively hotter process gas inlet and an exit port, a moisture removing filter coupled to the exit port, the moisture removing filter including a relatively colder gas exit, and a drain valve coupled to the moisture removing filter. The heat exchanger, the moisture removing filter, and the drain valve are all located in a thermally-insulated enclosure. A fan is placed outside the thermally-insulated enclosure and forces ambient air over the heat exchanger. The ambient air is sufficient to maintain a temperature above a water freezing temperature in the thermally-insulated enclosure even if the ambient air is below the water freezing temperature.Type: GrantFiled: August 28, 2023Date of Patent: June 10, 2025Assignee: Qnergy Inc.Inventor: David Leonard

Publication number: 20240052797Abstract: A method for operation of a closed-cycle power conversion device includes receiving measured thermal information from one or more sensors that sense thermal characteristics of a hot portion of an absorber heat exchanger of a closed-cycle power conversion device which uses a working medium in its operation. The closed-cycle power conversion device is in thermal connection with a heat source, and absorption of heat from the heat source is proportional to a mass or mass flow rate of the working medium. If the measured thermal information is not in a defined normal range, a message is provided of an abnormality in operation of the closed-cycle power conversion device.Type: ApplicationFiled: August 10, 2023Publication date: February 15, 2024Applicant: Qnergy Inc.Inventors: David Leonard, Isaac Garaway, Ben Figlin, Allen A.
