Scientific novelty
The invention relates to methods for year-round temperature stabilization of soil and can be used in the construction and operation of various facilities in permafrost areas remote from centralized power supply and lacking their own reliable and economical generation sources. For soil thermal stabilization, it is proposed to use vapor-liquid thermosyphons with additional inlets for connecting a refrigeration machine. A distinctive feature is the use of heat released at the thermosyphon condenser to heat a thermally insulated container housing energy storage units and other equipment sensitive to ambient temperature. The refrigeration machine is powered by renewable energy sources, such as photovoltaic or wind power plants, as well as energy storage units and, optionally, a backup power source.
Advantages
The method enables reliable year-round thermal stabilization of permafrost soils using energy from renewable sources. The beneficial use of heat released at the thermosyphon condenser improves the energy efficiency of the soil thermal stabilization process.
Commercial implementation
In thermal stabilization systems for facilities in the Arctic zone of the Russian Federation
