Patent number: 10704493Abstract: A device for compressing a gaseous fluid includes a first chamber thermally coupled with a hot source, a second chamber thermally coupled with a cold source, a movable piston moved by a rod, and a regenerating exchanger establishing fluid communication between the first and second chambers. The rod is arranged in a cylindrical socket and guided in axial translation by a linear guiding system such as to guide the piston without contact relative to the sleeve. A sealing ring attached to the cylindrical socket surrounds the rod with a very low radial clearance, in order to limit the passage of the gaseous fluid along the mobile rod. Also disclosed is an integral cold casing having machined boreholes, a thermal screen in the hot casing, and a self-driving system with a resilient return means.Type: GrantFiled: July 18, 2018Date of Patent: July 7, 2020Assignee: BOOSTHEATInventors: Jean-Marc Joffroy, Martin Bidar, Luc Dando

Patent number: 10539124Abstract: A thermodynamic boiler for exchanging (providing or drawing) heat with a heating circuit includes a thermal compressor. The thermal compressor acts on a compressible fluid and includes at least one compression stage, with an alternating bi-directional piston separating a first chamber and a second chamber, and a first fuel burner forming a heat source coupled to the first chamber. The thermal compressor uses the heating circuit as a cold source coupled to the second chamber and forms the compression function of a reversible heat pump type loop.Type: GrantFiled: October 20, 2016Date of Patent: January 21, 2020Assignee: BOOSTHEATInventor: Jean-Marc Joffroy

Patent number: 9273681Abstract: A gaseous fluid compression device includes: a first enclosure within which there is a movable first piston delimiting a first chamber and a second chamber; a second enclosure within which there is a movable second piston delimiting a third chamber and a fourth; a first exchange circuit connecting the first chamber and the fourth chamber, with a heat exchanger linked to a heat sink; a second exchange circuit connecting the second chamber and the third chamber, with a second heat exchanger linked to a heat source; and a transfer passage connecting the first chamber and the second chamber with an anti-backflow device. A back-and-forth movement of the interconnected pistons results in a compression of the gaseous fluid in the direction of the outlet.Type: GrantFiled: February 8, 2012Date of Patent: March 1, 2016Assignee: BOOSTHEATInventor: Jean-Marc Joffroy
