CREATION OF ENERGY SAVING RADIANT AND CONVECTIVE DEVICE FOR THAWING OF FROZEN SOILS

plied to the creation of a new mobile device for thawing of frozen soils. We present a study sets the existing devices, methods and techniques used for thawing of frozen soil, elicit their disadvantages. The requirements for a new device are defined, for example the time for thawing of 1 m 2 of frozen soils should be no more than 3 hours. The requisite thermal power of the device is defined (15 kW), as well as the relation of the depth of freezing and time based on the proposed mathematical model and the results of natural and laboratory tests. The article also reviews the technical characteristics, principle of function, general form and the main advantages of the new mobile radiation and convective device. It gives an assessment of the device efficiency based on the comparative characteristics of technical means. The fulfilled work and studies have shown the expediency of radiation-convective method for thawing frozen soils.
