Description

TECHNICAL FIELD

The invention relates to a device for cooling the lower layers of the atmosphere which comprises a support tube sleeve filled with a buoyant carrier gas, wherein at least one air-conducting tube is arranged in parallel in the support tube sleeve, the lower end if the air-conducting tube is located in the lower layers of the atmosphere, especially near the Earth's surface, wherein the upper end of the air-conducting tube is located in the upper layers of the atmosphere, especially in the upper layers of the troposphere or in the stratosphere.

BACKGROUND ART

Devices and processes for mitigating the global warming of the planet Earth are known from the background art, which comprise vertical ducts for the removal of warm air from the Earth's surface to the upper layers of the atmosphere. JP2015102291 discloses a pipe which carries warm air from the ground floor of a high-rise building to its roof, where it is discharged, warming the upper layers of the atmosphere, thereby increasing their radiation of heat to space and, due to the natural flow between the upper and lower layers of the atmosphere, cooling the air near the Earth's surface. Other known devices for mitigating the global warming move warm air from the Earth's surface even higher, above layers of the troposphere with high concentrations of greenhouse gases that prevent heat from radiating from the Earth's surface into space. WO2021038008A1 discloses a device which includes a chimney for removing warm air from the Earth's surface through the troposphere and the tropopause into the lower layers of the stratosphere. JPH1070941 describes a duct for removing warm air from the Earth's surface above clouds that otherwise prevent the heat of the Earth's surface from radiating into space. The disadvantage of these devices comprising a chimney, a pipe, a tube, etc., for removing warm air from the Earth's surface to the upper layers of the atmosphere is that they do not comprise suitable technical means for simultaneous and localized cooling of the lower layers of the atmosphere and rely only on the action of natural vertical flow, which can lead to unpredictable changes in the natural vertical flow of the Earth's atmosphere, to unexpected and unwanted cooling/warming of various parts of the Earth's surface, to undesirable atmospheric phenomena and lower efficiency of the device.

The object of the invention is therefore to eliminate or at least reduce the drawbacks of the background art by a device which will allow, either alone or as part of a system for mitigating the global warming, to effectively cool the lower layers of the atmosphere at a selected location.

SUMMARY OF INVENTION

The object of the invention is achieved by a device for cooling the lower layers of the atmosphere which comprises a support tube sleeve filled with a buoyant carrier gas, wherein at least one air-conducting tube is arranged in parallel in the support tube sleeve, wherein the lower end if the air-conducting tube is located in the lower layers of the atmosphere, especially near the Earth's surface, wherein the upper end of the air-conducting tube is located in the upper layers of the atmosphere, especially in the upper layers of the troposphere or in the stratosphere, wherein at least one air-returning tube is assigned to the air-conducting tube, the upper end of the air-returning tube being assigned to the upper end of the air-conducting tube, wherein the lower end of the air tube is spaced apart from the lower end of the air-conducting tube, and the support tube sleeve is provided with an interface for filling and discharging the buoyant carrier gas.

The device cools the lower layers of the atmosphere at a selected location by discharging cooled air which is removed from the lower layers of the atmosphere in another, distant, place, thus minimizing mixing of the removed air with the discharged cooled air and increasing the efficiency of the device operation. In addition, the device eliminates or at least reduces the leakage of cooled air into the upper layers of the atmosphere and the related pressure drop of the cooled air at the upper end of the air-returning tube, thereby further increasing the efficiency of the device operation.

Preferred embodiments of the device for cooling the lower layers of the atmosphere are the subject of dependent claims.

The lower end 31 of the air-returning tube 3 is horizontally and/or vertically spaced from the lower end 21 of the air-conducting tube 2 at a distance d₁ which is equal to or greater than the minimum distance that guarantees that the cooled air discharged from the lower end 31 of the air-returning tube 3 into the surrounding lower layer of the atmosphere is not sucked into the lower end 21 of the air-conducting tube 2.

The diameter of the air-returning and/or the air-conducting tube 3, 2 ranges from 0.5 m to 30 m, preferably from 1 m to 10 m, more preferably from 2 m to 5 m.

The upper end 32 of the air-returning tube 3 is assigned to the upper end 22 of the air-conducting tube 2, for example (FIG. 1) at a distance d₂ 20 m, but in another embodiment it may be assigned at a distance of 1 m to 200 m, as desired, e.g., according to weather conditions, the diameter of the tubes 2, 3, according to the number of the air-returning tubes 3 assigned to one air-conducting tube 2 (see FIGS. 2, 3a and 3b), according to the connection of the upper ends 22, 32 of the tubes 2, 3 by an upper connecting part 4a (FIGS. 4, 6, 7 and 8), etc.

The lower end 31 of the air-returning tube 3 is spaced apart from the lower end 21 of the air-conducting tube 2, for example (FIG. 1) at a distance d₁ 100 m, but in another embodiment may be spaced apart by 10 m to 1000 m, or substantially any other distance longer than 10 m, as required, e.g., according to weather conditions, the diameter of the tubes 2, 3, the number of the air-returning tubes 3 assigned to one air-conducting tube 2 (see FIGS. 2, 3a and 3b), etc.

The advantage of the device provided with the upper connecting part 4a is that all or substantially all of the air which during the operation of the device flows from the upper end 22 of the air-conducting tube 2, is sucked through the upper connecting part 4a into the upper end 32 of the air-returning tube 3, so that there are no leaks or substantially no leaks of the cooled air to the upper layers of the atmosphere, wherein the air is cooled when passing through the upper connecting part 4a.
