Blinds for the intelligent use of solar energy

Abstract

Venetian blind with adjustable, both horizontal and vertical slats (1) of any size, both sides of which have different colors, characterized in that the first side (2) of the slats is dark, in particular black, in order to absorb incident solar energy to the maximum and thus heat the interior.

Description

Technical area:

[0001] The invention relates to a blind with adjustable, both horizontal and vertical slats (1) of any size, both sides of which have different colors. The blind is particularly suitable for regulating the energy input from solar radiation in residential buildings, offices, and commercial buildings. State of the art:

[0002] Conventional sun protection systems such as standard blinds or roller shades primarily serve to regulate light and provide privacy, but they offer only limited options for specifically controlling heat absorption or reflection of solar energy. While dark blinds or roller shades absorb solar energy and thus contribute to warming a room, lighter versions reflect light and prevent excessive heating. A disadvantage of these systems is that they serve either solely as heat storage or heat protection, without being able to respond flexibly to changing environmental conditions. In addition, darkening through conventional systems leads to a reduction in daylight and the associated need for artificial lighting. Solution:

[0003] The invention solves this problem by providing a blind with adjustable slats (1), the first side (2) of which is dark, particularly black, to maximize the absorption of incoming solar energy and heat the interior. The second side (3) is light, particularly white or silver, to reflect solar energy and prevent excessive heating of the interior. The variable inclination of the slats (4) allows the optimal balance between heat gain, heat protection, and light transmission to be set. This ensures energy-efficient use of solar energy without compromising living comfort due to excessive darkening. Example:

[0004] A preferred embodiment of the blind comprises a horizontal arrangement of the slats on a south-facing window surface. This is shown by the Fig. 1 and Fig. 2. They show: Fig. 1 Example of a slat, Fig.2 Arrangement of the slats towards sunlight.

[0005] In winter or transitional periods when temperatures are below the comfortable limit, solar energy should be used for heating by optimally aligning the slats with the dark (or black) side (2) towards the sun so that as much solar energy as possible is absorbed.

[0006] In summer or transitional periods when temperatures are above the comfortable limit, the solar energy should be reflected by optimally aligning the slats with the light (or white or silver) side (3) towards the sun as heat protection, so that the solar energy heats up the room as little as possible, in order to avoid this room having to be cooled with an air conditioning system and thus consuming energy.

[0007] To prevent complete blackout from compromising the lighting comfort and necessitating the use of less attractive, energy-consuming artificial lighting, a Venetian blind was chosen that allows the slats to be tilted by rotation (4). Thus, when optimally adjusted, it provides sufficient indirect sunlight (6) for interior lighting, which is also physiologically beneficial. With horizontal slats, this is possible even with optimal energy generation, up to a horizontal position of the slats, so that this position allows a complete view and further enhances living comfort.

[0008] The use of the invention significantly reduces the energy consumption and thus the CO2 footprint and contributes significantly to environmental protection.

[0009] The simple, familiar mechanical technology of slatted blinds means that no additional mounting materials or other tools are required.

[0010] Venetian blinds can generally be installed by the customer themselves, so that the scarce resource of tradespeople is not required and thus additional costs and time are saved.

[0011] The very low cost of thermal blinds compared to other energy generators brings a significant energy cost advantage and thus helps to avoid having to compromise on living comfort even when energy costs are rising.

[0012] Motorized thermal blinds offer an optional automated optimization of solar energy utilization or rejection. Connection to all types of communication systems, such as Bluetooth or Wi-Fi, enables remote control via smartphone, tablet, or PC apps.

[0013] The thermal blind therefore represents an efficient and flexible solution for the intelligent use of solar energy and makes an important contribution to energy saving and sustainability in buildings.
