METHOD FOR USING SOIL HEAT ACCUMULATION PROPERTIES Russian patent published in 2013 - IPC F24D11/00 

FIELD: heating.

SUBSTANCE: method for using soil heat accumulation properties involves arrangement in the soil of sealed heat exchangers or thermowells, arrangement of circulation of heat carrier via them and extraction from soil and/or discharge to the soil of low-potential heat energy. The method provides for moistening of an enveloping heat exchanger or a thermowell of capillary porous soil mass and introduction to the heat exchange process of latent heat of phase transitions of porous moisture contained in the soil. Soil moistening is performed in cycles. In the heat supply mode, heat carrier temperature at the inlet of the heat exchanger or the thermowell is automatically maintained at the level that does not exceed the water freezing temperature of capillary porous structure of soil mass. Condensate and/or rain water is used in the mode for conditioning and discharge of heat energy to the soil for dampening of soil mass.

EFFECT: energetically and environmentally effective heat and cold supply to buildings and structures of different purpose.
