HEAT MACHINE CONFIGURED FOR REALIZING HEAT CYCLES AND METHOD FOR REALIZING HEAT CYCLES BY MEANS OF SUCH HEAT MACHINE

A heat machine (121) for realizing a heat cycle, the heat machine operating with a thermal fluid and comprising a drive unit (1) provided with a first rotor (4) and a second rotor (5), each having three pistons (7a, 7b,7c; 9a,9b,9c) that are slidable in an annular chamber (12), wherein the pistons delimit six variable-volume chambers (13', 13", 13"'; 14', 14", 14"'). The drive unit comprises a transmission configured to convert the rotary motion with respective first and second periodically variable angular velocities (ω1, ω2) of said first and second rotor (4, 5), offset from each other, into a rotary motion at a constant angular velocity. The heat machine further comprises a compensation tank (44), configured to accumulate the compressed thermal fluid from the drive unit, a regenerator (42) configured to preheat the thermal fluid, a heater (41) configured to superheat the thermal fluid circulating in the serpentine coil, a burner (40), configured to supply the necessary thermal energy to the heater (41); wherein the regenerator (42), in fluid communication with the drive unit (1), is further configured to acquire energy-heat from the exhausted thermal fluid and use it to preheat the thermal fluid to be sent to the heater (41). The invention further relates to a method for realizing a heat cycle by means of said heat machine.
