Abstract: Hybrid thermodynamic compressor (8) for compressing a working fluid, the compressor comprising a volumetric cylinder (1) and a thermal cylinder (2) connected to one another mechanically by a connecting rod system (5) and pneumatically by a connecting circuit (12) optionally with a valve (4), a reversible electric machine (6), the volumetric cylinder comprising a first piston (81) that separates a first chamber (Ch1) from a second chamber (Ch2), the thermal cylinder comprising a second piston (82) which separates a third chamber (Ch3) from a fourth chamber (Ch4), which can be brought into thermal contact with a heat source (21) to thereby generate a cycled movement in the thermal cylinder, and concerning the connecting rod system (5), the first and second pistons are connected to a rotor (52) by first and second respective connecting rods (91,92), with a predetermined angular offset (?d), the volumetric cylinder being equipped with non-return valves (61,62), the power produced in the thermal cylinder being tra

Abstract: 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.

Abstract: 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.

Abstract: A method indicates to a user the fuel consumption and/or efficiency of a heating installation having a heat pump with a thermal compressor, a heating fluid distribution circuit and radiators receiving a first quantity of energy Q1. The method includes the steps: A—of determining, over a predetermined time period a second quantity of energy Q2, corresponding to the supply of heat energy used to drive the compressor, B—of determining, over the same predetermined time period, a third quantity of energy Q3 corresponding to free energy taken from the external environment, C—of displaying the quantities Q2 and Q3, in relation to the predetermined time period, on a display screen and/or in a document for invoicing the customer.

Abstract: 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.

Abstract: A modular device for compressing gaseous fluid includes a first stage with a first hot chamber, a second cold chamber, a piston assembly separating the first and second chambers inside a main enclosure, a regenerative heat exchanger establishing a fluid communication between the first and second chambers by at least a first communication line, and optionally third and fourth chambers separated by a fixed divider separating the third and fourth chambers placed in communication by a second communication line. It thus includes a compressor with one, two, or four stages based on a modular architecture with common components.
