Description

The invention relates to heating equipment and can be used for low-temperature heating of buildings with the natural heat of the earth.

A known building heating system, comprising vertically mounted sealed pipes filled with coolant, partially buried in the soil of the building base below the freezing depth and provided with thermal insulation within the freezing depth.

A disadvantage of the known heating system is a decrease in the intensity of circulation of the heat carrier in the pipes as the temperature inside the building rises due to a decrease in the temperature difference between the heat source and the temperature inside the building, which prevents the temperature inside the building from rising to the temperature of the heat source.

The purpose of the invention is to enhance heat transfer.

The goal is achieved in that the heat-transmitting devices are made in the form of heat pipes partially filled with a low-boiling coolant, while the upper ends of the pipes are bent and brought out with the ends of the cranked buildings to the outside, a pipe condensate is installed in each pipe, and installed on a bent section located in the wall a vertical partition made of heat-insulating material passing through the walls of the pipe and provided with a vapor hole in the upper part and a liquid hole in the lower part, and at the location ednego connected to the partition condensate inlet end, an outlet end which is bent upwards and is located in the evaporator below the liquid level.

The proposed device is shown in the drawing in longitudinal section.

The heating system comprises sealed heat pipes 1 located on the inner perimeter of the building, each of which has a bent upper end, is partially filled with low-boiling liquid 2 and evacuated. The lower end of the heat pipe is buried in the soil of the base of the building below the freezing boundary of the soil, within which the outer surface of the heat pipe is covered with thermal insulation 3. The upper bent end of the heat pipe is brought out by the end 5 through the wall 4 of the building and communicates with the external environment. Section 6 of the heat pipe located in the wall of the building is divided by a vertical heat-insulating partition 7, the upper part of which has an opening 8 for steam and a lower hole for condensate, which

is discharged through a heat-insulating condensate conduit 9, the output end 10 of which is bent upward and located in a low-boiling liquid 2.

The device operates as follows.

At the lower end of the heat pipe 1, a low boiling liquid 2 boils and evaporates from the natural heat of the lower layers of the earth.

0 Steam rises and heats the non-insulated bent end of heat pipe 1 located inside the building, which in turn transfers heat to the interior of the room and then the steam

5 through the hole 8 in the partition 7 enters the space of section b, enclosed between the end face 5 and the partition 7, where the temperature is cooled from the end wall 5 in communication with the external environment

0 which is much lower than the temperature inside the room and therefore the condensation of the vapor in this space will be more intense. Condensate formed in reverse thermally insulated

5, pipe 9 returns to the lower end of heat pipe 1, closing the coolant circulation system.

In order for the vapor bubbles of the boiling liquid 2 to rise

0 at boiling, could not get into the return pipe 9, its end 10 is bent up. And so that the external cold does not spread down the pipe 1, its upper end is separated by a heat-insulating partition 7.

5 The proposed device can be used for heating vegetable stores, garages, warehouses, cowsheds in winter with the low-temperature natural heat of the underlying layers of the earth.
