Abstract
A new constructive device for temperature stabilization of frozen soils is suggested. The advantage of the proposed system is the ability to install the evaporative part of the system under construction and operating facilities. The difference from analogs is the ability to repair and replace individual evaporator pipes without dismantling the entire device while maintaining its high freezing capacity. To assess the efficiency of the proposed system, an analytical mathematical model of its functioning has been developed. The modeling of the functioning of the seasonal cooling device for the climatic conditions of the Arctic cities Varandey, Salekhard, and Igarka has been carried out. It is shown that this device can always freeze the soil under emergency buildings and structures.
