Abstract

The invention relates to construction, in particular to structures providing protection from direct sunlight. The aim of the invention is to increase the efficiency of the device due to protection from direct sunlight, additional natural light from the room far from the light room and effective use of solar radiation. The sun protection device is made in the form of a screen mounted on the outer side of the frame of the opening with the possibility of rotation when the height of the Sun's surface changes. The screen is made of two sections 3 and 4, pivotally connected at an angle to each other and equipped with solar receivers 5 and 6 with energy diverting elements. The screen section hinges from the light-beam and is hinged to the bottom side of the light-beam. The upper surface farthest from the light-emitting section of the screen is covered with a shell 7 made of a material with a highly reflective in the visible region of the solar spectrum and a high-transmitting ability in the infrared region and has the shape of a truncated circular torus segment. The screen is installed with the help of telescopic consoles 8, one end of which is rigidly connected to the screen section distant from the light aperture, and the other end is hingedly fixed with a possibility of fixation under the light aperture. Elements that divert energy are passed through the console. 3 il.

Description

The invention relates to the construction, in particular, to devices that contribute to creating a comfortable light environment in rooms, protecting them from direct rays of the sun, using solar energy.

The purpose of the invention is to increase the efficiency of the device due to protection against direct sun rays, additional natural illumination of the outer zone of the room and effective use of solar radiation.

Figure 1 shows a fragment of a section of a multi-storey building with an installed system of sun protection devices; 2 shows a fragment of a multistory building; on fig.Z - the proposed device, the cut.

The sun-protection device is made in the form of a screen fixed with the possibility of rotation and fixation on the outside of the building envelope 1 and the lower horizontal side of the wind-opening 2. Moreover, the screen consists of two sections 3 and 4 pivotally connected with one another. Both sections of the screen are equipped with solar collectors 5 and b with energy diverting elements. The outer surface of section 4 is covered with a shell 7 in the form of a truncated segment of a circular torus made of a material with a high reflectivity in the visible region of the solar spectrum and a high infrared transmitting ability, for example, from hot-pressed lanthanum fluoride or from an interference-coated film. The energy diverting elements are placed in the console 8.

Sun protection device works as follows.

When the sun beams A and B hit the top of the screen, attached by means of consoles to the external enclosing structure 1 at the lower side of the aperture 2, the visible part of the radiation is reflected from the envelope 7 and directed into the room (rays A and B1 in Fig. 1) . The thermal part of solar radiation passes through the shell 7 and falls on the receiving surface of the solar collector 6, where it produces energy, which is discharged along. console elements.

changing the angle of inclination of the section of the screen 4, you can adjust the direction of reflection of Beams A1 and B. Beam A, which falls at point G, is the extreme one reflected in the room. Thus, the light active for the room is the screen section 4. In this connection, and for more efficient use of solar radiation, section 3 of the screen with a solar collector 5 is deployed relative to section 4. Radiation falling on the surface of the solar receiver is converted into one of the types of energy, which is also removed by an element located in the console 8. In this case, The role of sun protection is performed by the screen, which is a part of the upper room light-protective device.

At night, during the cold season, the device can act as heat shields. In this case, move the console so that both sections of the screen are adjacent to the window, reducing heat loss from the room through the translucent fencing.

The use of the invention in comparison with the known devices provides simultaneous protection from direct sunlight and additional natural room lighting in the summer and winter periods; greater efficiency in the use of natural light, and consequently, shorter time of using additional artificial lighting of rooms that have a significant laying depth, which leads to energy savings and lower operating costs: the possibility of building buildings with greater depth in the room; with the same normalized levels of natural light, a smaller (by about 10%) area of apertures in buildings equipped with sun-protection devices; the possibility of utilization of the heat of solar radiation; improved light distribution in rooms.

The use of solar collectors in sunscreen devices allows additional electrical energy to be obtained by converting the thermal part of solar radiation.
