An aircraft propulsion unit includes a nacelle in which a power plant is arranged. The nacelle includes an inside wall that delimits a pipe with an air intake at the front. The propulsion unit includes a frost treatment system having at least one first pipe equipped with elements for regulating the passing air, for directing the hot air from the power plant to the air intake, and, an exhaust system having at least one second pipe equipped with elements for regulating the passing air, for directing air from the power plant to a delivery zone. The at least one second pipe is connected to the at least one first pipe, and the elements for regulating the air that passes into the at least one first pipe are separate from the elements for regulating the air that passes into the at least one second pipe.

1. An aircraft propulsion unit that comprises: a nacelle in which a power plant is arranged, said nacelle comprising an inside wall that delimits a pipe with an air intake at a front of the nacelle;a propulsion unit comprising a frost treatment system that comprises at least one first pipe that is equipped with first means for regulating passing air, for directing hot air from the power plant to the air intake, and an exhaust system that comprises at least one second pipe that is equipped with second means for regulating the passing air, for directing air from a combustion chamber of the power plant to a delivery zone to be discharged into the air intake, and said at least one second pipe is connected to said at least one first pipe,wherein the first means for regulating air that passes into said at least one first pipe are separate from and parallel to the second means for regulating the air that passes into said at least one second pipe, and the first means for regulating air is a variable restriction. 2. The aircraft propulsion unit according to claim 1, wherein said at least one second pipe is connected to said at least one first pipe downstream from said first and second means for regulating the air that passes into said at least one first pipe and into said at least one second pipe. 3. The aircraft propulsion system according to claim 1, wherein the first pipe is connected to a first tapping point on the power plant through the first means for regulating the passing air, and the second pipe is connected to a second tapping point on the power plant through the second means for regulating the passing air. 4. The aircraft propulsion system according to claim 3, wherein the first tapping point and the second tapping point are arranged in a same zone of the power plant. 5. The aircraft propulsion system according to claim 3, wherein the first tapping point and the second tapping point are arranged in different zones of the power plant. 6. The aircraft propulsion system according to claim 1, wherein the second means for regulating the passing air is a valve. 7. The aircraft propulsion system according to claim 1, wherein the first means for regulating the passing air is different from the second means for regulating the passing air so as to optimize defrosting and exhaust. 8. An aircraft propulsion unit that comprises: a nacelle in which a power plant is arranged, said nacelle comprising an inside wall that delimits a pipe with an air intake at a front of the nacelle;a propulsion unit comprising a frost treatment system that comprises at least one first pipe that is equipped with a first air regulator, configured for directing hot air from the power plant to the air intake, and an exhaust system that comprises at least one second pipe that is equipped with second air regulator, configured for directing air from a combustion chamber of the power plant to a delivery zone to be discharged into the air intake, and said at least one second pipe is connected to said at least one first pipe,wherein the first air regulator is separate from and parallel to the second air regulator, and the first air regulator is a variable restriction. 9. The aircraft propulsion unit according to claim 8, wherein said at least one second pipe is connected to said at least one first pipe downstream from said first and second air regulators which regulates the air that passes into said at least one first pipe and into said at least one second pipe, and the first and second air regulators are arranged in parallel. 10. The aircraft propulsion system according to claim 8, wherein the first pipe is connected to a first tapping point on the power plant through the first air regulator, and the second pipe is connected to a second tapping point on the power plant through the second air regulator. 11. The aircraft propulsion system according to claim 10, wherein the first tapping point and the second tapping point are arranged in a same zone of the power plant. 12. The aircraft propulsion system according to claim 10, wherein the first tapping point and the second tapping point are arranged in different zones of the power plant. 13. The aircraft propulsion system according to claim 8, wherein the second air regulator is a valve. 14. The aircraft propulsion system according to claim 8, wherein the first means for regulating the passing air is different from the second means for regulating the passing air so as to optimize defrosting and exhaust. 15. An aircraft propulsion unit that comprises: a nacelle in which a power plant is arranged, said nacelle comprising an inside wall that delimits a pipe with an air intake at a front of the nacelle;a propulsion unit comprising a frost treatment system that comprises at least one first pipe that is equipped with a first air regulator comprising a variable constriction, configured for directing hot air from the power plant to the air intake, and an exhaust system that comprises at least one second pipe that is equipped with second air regulator comprising a valve, configured for directing air from a combustion chamber of the power plant to a delivery zone to be discharged into the air intake, and said at least one second pipe is connected to said at least one first pipe,wherein the first air regulator is separate from and parallel to the second air regulator. 16. The aircraft propulsion unit according to claim 15, wherein said at least one second pipe is connected to said at least one first pipe downstream from said first and second air regulators which regulates the air that passes into said at least one first pipe and into said at least one second pip, and the first and second air regulators are arranged in parallel. 17. The aircraft propulsion system according to claim 15, wherein the first pipe is connected to a first tapping point on the power plant through the first air regulator, and the second pipe is connected to a second tapping point on the power plant through the second air regulator. 18. The aircraft propulsion system according to claim 17, wherein the first tapping point and the second tapping point are arranged in a same zone of the power plant.
