Abstract

The invention relates to agriculture, in particular to devices for autonomous heating of the soil. The purpose of the invention is to save energy and enhance functionality. The heating system of the soil with wind power unit 1 contains heating elements 2, placed in the soil. The principle of operation of the heating elements 2 is based on the flameless oxidation of gasoline vapors in the presence of a catalyst when they reach a certain temperature. The heating elements 2 are connected by pipelines 15 to the fuel pump 3 and the pipes 16 to the compressor 5. Each heating element 2 has an electric heater 33 for pre-heating the heating element body 2. The heating process is controlled by thermal sensors 34 which regulate the operation of electric heaters 33 by means of a logic unit 8 through switches 19. Wind power installation 1 is connected to the system as an autonomous power source. With sufficient installation power 1, the wind pressure sensor 11 outputs through the element AND a signal to turn off the power network with the switch 13. The system is powered from the wind power installation until it drops below the installed power when switching to power from the power grid. 1 hp f-ly, 4 ill.
