SYSTEM FOR COOLING AND FREEZING SOIL Russian patent published in 2017 - IPC E02D3/115 

FIELD: construction.

SUBSTANCE: system including the installation of underground heat exchangers with a liquid coolant with a freezing point below zero degrees centigrade (brine) is described, characterized in that cryopegs are used as a liquid coolant, a cryopeg being fed to freezing columns from the cryolithozone into the heat exchangers. Spent cryopegs can be forcibly discharged to the cryolithozone massif. The outer part of the circulation circuit can be thermally insulated. The technical result of profitability increase is achieved by the absence of energy-consuming refrigerating machines and by the absence of the need to prepare a special cooling solution. The technical result of reliability increase is achieved by reducing the number of system components, the failure probability of each of which differs from zero. The technical result of operation stability increase is achieved by the temperature stability of the cryopeg, the total amount of which considerably exceeds the amount of the cryopeg used during the season. The invention can be successfully applied in the construction of industrial and civil buildings.

EFFECT: increasing the economy, reliability and stability of operation.
