Device for directing cold air to warmer locations

Abstract

As part of climate change, which is obviously happening and affecting many parts of the world, buildings and spaces where people live and work are also getting hotter and hotter in the summer. There are many ways to cool these buildings and rooms within these buildings: be it sun protection in front of or films on the windows, the thermal insulation of the building, the air conditioning, the fan. A heat pump, whether a groundwater pump or a geothermal heat pump, extracts heat from the environment through heat exchange via a fluid medium. Due to the law of thermodynamics, which states that heat tends towards a mean temperature, this process effectively introduces cold into the building. In contrast to the methods presented above, this device for conducting cold to warmer places uses a very strong, thermally conductive material, preferably copper, as the medium for heat exchange. This facility is structured as follows: From a heat receiver (1), heat or cold exchange takes place through a highly thermally conductive, very well insulated line (2, 2a, 2b, 12) to the heat emitter (3, 8, 8a, 9, 10). The heat sensor is installed in the foundation (4) of a building or below the ground surface under (5) or next to (6) a building. The building may have a basement or be built without one. The volume or mass of the heat exchanger can comprise several to many cubic meters or tons, possibly divided into plates and / or meshes, depending on the size of the building or rooms to be cooled. If required, several such facilities can be fully or partially connected to each other in a building (11, 11a) or installed individually (11). In a new building, this facility can be planned from the outset by being installed in the foundation (4) or in the ground under the foundation (5) and in the walls (2) etc.

Description

[0001] As climate change is clearly taking place and affecting many parts of the world, the buildings and spaces where people live and work are also becoming increasingly hotter in the summer. This poses an increasing threat to living and working conditions, as well as physical health.

[0002] There are many ways to cool these buildings and rooms within them: be it sun protection or film on the windows, thermal insulation of the building, air conditioning, or fans.

[0003] All these means are intended to prevent heat from penetrating into buildings and rooms, or to ensure that cooler air is supplied or produced, or to achieve a cooling effect through airflow.

[0004] In the area of ​​geothermal energy use, it is also known that in summer, buildings or rooms within them can be cooled by the heat pump using this principle: The heat pump, whether as a groundwater pump or geothermal heat pump, extracts heat from the environment through heat exchange; by means of a liquid medium, a liquid is pumped from layers of the earth that are cold compared to the temperature above ground; this liquid is then pumped to the heat exchanger and then into the heating system of a building.

[0005] Due to the law of thermodynamics, which states that heat tends towards an average value, cold is, so to speak, introduced into the building.

[0006] It is well known that the temperature in the ground and in the earth is lower than in the layers above the earth's surface: in Germany the temperature at a depth of about 4 m below the earth's surface is about 11° Celsius in both summer and winter, and even at a depth of just 0.5 m the temperature is only 18° Celsius in summer, even when the air temperature is 30° Celsius.

[0007] In contrast to the options presented above, this device for conducting cold to warmer places uses a very solid heat-conducting material, primarily copper, as the medium for heat equalization.

[0008] This facility is structured as follows: From a heat absorber (1,) the heat or cold exchange takes place through a very heat-conducting, very well insulated line (2, 2a, 2b, 12) to the heat emitter (3, 8, 8a, 9, 10).

[0009] The heat sensor is installed in the foundation (4) of a building or below ground level (5) or next to (6) a building. The building may have a basement or be built without one.

[0010] This heat absorber is made of a highly heat-conducting material, preferably copper. The heat absorber in the foundation or soil is designed and dimensioned to have the largest possible surface area, providing a direct and immediate connection to the surrounding foundation or soil without insulation.

[0011] The heat absorber can have the shape of one or more plates or cuboids or a fine mesh.

[0012] The volume or mass of the heat absorber can range from several to many cubic meters or tons, possibly divided into plates and / or networks, depending on the size of the building or room(s) to be cooled.

[0013] A highly thermally insulated pipe made of this highly heat-conducting material is then laid in the building's foundation or in the ground, completely connected to this heat absorber. This connection is designed to prevent heat loss. This pipe can be attached to as many different locations (7) as possible on the heat absorber, ensuring that heat extraction from the heat absorber is highly differentiated and effective, and then combined into a single pipe.

[0014] This line is connected to a heat emitter inside the building / building section or in one or, if separated, several rooms (8, 8a). This connection is designed to minimize heat loss. The heat emitter is located in the building / building section or in the room(s) where the temperature is higher than that of the heat absorber and where cooling is required.

[0015] This heat emitter is made of a highly heat-conducting material, preferably copper. This heat emitter is designed and dimensioned to have the largest possible surface area, which has a direct and immediate connection to the surrounding air or to building components.

[0016] The heat emitter can have the form of one or more plates (9) or a fine mesh (10).

[0017] The volume or mass of the heat emitter can range from several to many cubic meters or tons, possibly divided into panels and / or networks, depending on the size of the building / building section or the room(s) to be cooled.

[0018] If necessary, several such devices can be installed in a building, either fully or partially interconnected (11, 11a) or individually (11).

[0019] The heat compensation then takes place in one (2) or more (2a, 2b) lines into the building from the heat absorber to the heat emitter via one or more lines, which are then attached to as many and as different (7) locations of the heat absorber or to different heat absorbers (1, 11).

[0020] The efficiency of the extraction of the “earth’s cold” must correlate with the volume of the building / building part or room to be cooled.

[0021] But even with a low efficiency, it has been proven that there is always a certain effect; there is always a saving in the use of electricity when using the other cooling methods mentioned above.

[0022] In a building, it is often sufficient for the pipe to be led only to the upper floor or the attic, since temperatures there are highest in summer.

[0023] It is often sufficient to route the cable into only one room of the building, e.g. a room facing the south side of the building which is used for professional purposes.

[0024] In a building, it may be useful to install several such devices (5, 6, 11) or to lay several strong lines from a heat absorber (9, 10) to different heat emitters.

[0025] This can be useful if the rooms or parts of the building to be cooled are located far away or on different floors.

[0026] Provision should be made for the line to be interrupted or disconnected. This may be necessary when the temperature difference reverses, for example, at night or in winter.

[0027] This may consist of a mechanical separation between the various elements of the system, although this separation device must be very well insulated against heat loss.

[0028] In a new building, this facility can be planned from the outset with installation in the foundation (4) or in the ground under the foundation (5) and in the walls (2) or similar.

[0029] In the case of subsequent installation, the heat absorber is installed in the ground next to the building (6), and the pipes are led to the relevant rooms in the shadow area of ​​the building in extra well-insulated ducts on the outside of the building wall (12).

[0030] The advantage of this device for transferring cold to warmer places is, on the one hand, that naturally existing heat differences between the ground and the foundation of a building and the air above it are used, without the need to generate additional energy for heat exchange (“cold recovery”) and cold transport.

[0031] On the other hand, this device is maintenance-free, and after the one-time installation, no subsequent effort is required for operation.
