ICEBREAKER POWER PLANT Russian patent published in 2024 - IPC F02G1/04 F03G7/05 B63B35/08 F25B27/02 F01B23/08 

FIELD: mechanical engineering.

SUBSTANCE: icebreaker power plant includes combined compressor 1 with pneumatic motor 2. Crankshafts 3 of compressor 1 and air motor 2 are connected to each other by coupling 4. The crankshaft of compressor 1 is connected through output shaft 3.1 to unit for changing the rotation speed 13. Compressor 1 and air motor 2 include a cylinder-piston group, as well as a cylinder head with an intake and exhaust system with valve mechanisms. The outlet unit of pneumatic motor 2 along the first circuit of the pipeline is connected to air heat exchanger 6 located on the icebreaker in the open air, and is further connected to intake unit 7 of compressor 1 to transfer freon cooled to ambient temperature. The outlet unit of compressor 1 along the second circuit of the pipeline is connected to water heat exchanger 9 located at the bottom of the icebreaker in direct contact with water and is further connected to air motor inlet unit 10 to transfer expanded freon heated to a given temperature to operate the air motor. Two-way valve 11 is installed in the second circuit of the pipeline to redirect and adjust the degree of freon supply, bypassing water heat exchanger 9 to adjust the speed of the air motor or completely stop it.

EFFECT: creation of an effective power plant for areas with permafrost using renewable natural energy sources, providing low energy consumption with a simple design.
