The disadvantages of this device is a metal-intensive design, which entails an increase in the cost of installation and construction works and increases the complexity and assembly time and high cost of the product.

The objective of the utility model is to reduce the metal consumption of structures, the cost of installation and construction works, the complexity and assembly time, thereby reducing the cost of manufacturing a device for accumulating cold.

This technical result is achieved in that a device for accumulating cold, including a casing pipe filled with refrigerant and consisting of an evaporator immersed in the ground, a condenser consisting of condenser zones A and B, discharge and discharge pipelines, a condensing unit located above the condenser and connected by discharge and discharge pipelines with a pipeline acting as an evaporator, made in the form of an elliptical tube tightly wound on a condenser, located nym in zone A, and the casing itself is formed as a steel tube, mounted in the concrete pile.

The device includes a casing pipe, made in the form of a steel pipe 1, mounted in a reinforced concrete pile 2 and consisting of an evaporator 3, immersed in the ground, and a condenser 4, consisting of condenser zones A and B, around the condenser zone A there is a pipe 5 acting as an evaporator and made in the form of an ellipse-shaped tube tightly wound around the casing, moreover, metal elements 6 are additionally radially arranged around the pipe in the evaporator zone to increase the thermal conductivity of the concrete pile wall. Around the pipe 5 is mounted shell 7 with thermal insulation. The device for accumulating cold comprises a compressor-condenser unit 8, consisting of a compressor 9 with a discharge pipe 10 and a condenser 11 located under the capacitor 3 on a continuous frame 12 made of opaque material, and connected by a discharge pipe 13 and a discharge pipe 14 using

thermostatic valve 15 and using the hermetic coupling 16 with the pipeline 5.

The device operates as follows.

With the onset of the period when the average daily outdoor temperature drops below 0 ° C, cooling and freezing of the soil occurs due to the circulation of refrigerant in the casing evaporator 3. Condensation occurs in capacitor zone B.

With the onset of the period when the average daily outdoor temperature becomes higher than 0 ° C, in the casing, made in the form of a steel pipe 1, mounted in a reinforced concrete pile 2, the pressure increases and the refrigerant circulation stops and the condensing unit 8 is turned on. Due to the circulation refrigerant in the condensing unit 8, the pressure in the casing decreases. The refrigerant from the compressor-condenser unit 8 located under the condenser 4 on the continuous frame 12 from the opaque material enters the discharge pipe 13, and then into the condenser zone A and into the pipe 5, made in the form of an ellipse tube tightly wound on the casing, where through heat transfer there is a condensation of the refrigerant located in the condenser in zone A. Next, the refrigerant vapor from the pipeline 5 enters the discharge pipe 14 and returns to the condensing unit unit 8, where they are compressed, condensed, and through the discharge pipe 13, the refrigerant returns to the condenser zone A, and the cycle repeats.

Due to the fact that the device for accumulating cold contains a steel pipe mounted in a reinforced concrete pile, this device can reduce the metal consumption of the structure, reduce the cost of installation and construction works, the complexity and assembly time, thereby reducing the cost of manufacturing the device.

The device is manufactured as follows

We wind a pipe 5 onto a steel pipe 1, made in the form of an elibist tube, which we then cover with a sheath 7 with thermal insulation to prevent tube deformation and reduce the supply of heat from the environment. Next to the steel pipe 1 along the entire length we fasten the steel elements 6, positioning radially to the pipe to increase the thermal conductivity of the piles. After assembling the metal structures, we immerse it in a mold for pouring concrete piles. When the concrete has hardened, the pile is driven into the ground.

Due to the fact that the device for accumulating cold contains a steel pipe mounted in a reinforced concrete pile, this device can reduce the metal consumption of the structure, reduce the cost of installation and construction works, the complexity and assembly time, thereby reducing the cost of manufacturing the device. And also the use of this device significantly increases the reliability of equipment that will be mounted on a pile, and also makes it possible to mount it both in permafrost soil and on soils with low bearing capacity.
