Description

The utility model relates to ventilation and air conditioning systems, and specifically to the design features of overhead, reflective and air-distribution screens for wall-mounted air conditioners used for rooms with a ceiling height, mainly 2.5-2.63 m.

The prototype of an overhead reflective screen for air flows is a screen (RF patent for utility model No. 162998, publ. 10.07.2016), made with the possibility of fixing on vertical structures (building, on the wall) at an angle of 15-45 ° to the surface, lateral the walls of which are made airtight, and in its upper part there is an outlet opening, and the screen is made in the form of an inverted bell segment. The design provides a reduction in the speed of air flows, the acoustic characteristics of the ventilation grill, by redirecting the air stream at an angle of 15-45 ° to the wall surface.

The technical result of the claimed utility model is to increase the reliability of operation of the overhead reflective screen of the wall-mounted air conditioner due to the adjustable stiffness of the structure, the length of the reflective front panel by a given number of stiffening ribs, and, in general, to increase the aerodynamic characteristics that provide a comfortable microclimate and sanitary conditions for people in the entire room. An additional advantage is the quick assembly and disassembly of the screen associated with cleaning, carrying and transporting.

The task is achieved by the fact that the overhead reflective screen of the wall-mounted air conditioner is made segment-shaped, airtight with the possibility of fixing on a vertical wall under the air conditioner using hooks and located at an angle to the wall, and the reflective screen in the cross-section is made in the form of a segment of the front panel with a radius of R = 257 ± 2 mm, on the edges of which, along the length of the screen, there are stiffeners in the form of rims at an angle of 35 ° with a width of 16 mm, each of which has fixing shaped grooves with an angle of = 35 ° for two fastening strips passing into stiffeners in the plane of which grooves are located - hooks with an angle of 35 ° for fixing in the sides of the front panel, in which three holes are additionally made for fixing the position of each strip and an additional hole in the center of the front panel for a stiffener with a lock, and fastening strips with stiffeners and a rib center rigidity is of the same curvature with the curvature of the faces th panel and make up an angle = 60 ° between the tangent to the surface of the stiffener of the front panel and the surface of the wall.

For a better understanding of the essence of the utility model, FIG. 1-5 shows an inclined reflective screen to a wall-mounted air conditioner, where

1 - a fastening bar with a stiffener

2 - stiffener

3 - front panel

4 - fastening holes in the fastening plate 1

5 - bezel of the front panel 3

6 - hole for the position lock (s) on the front panel 3

7 - position lock

8 - groove-hook in stiffeners

9 - fold line when forming a side 5

10 - groove for positioning the hook in the stiffeners

11 - hook for securing the screen (2 hooks)

12 - the wall to which the air conditioner 13 and the overhead reflective screen are attached

14 - cooled air flow.

The overhead reflective screen of the wall-mounted air conditioner is made of transparent polyethylene terephthalate (PET) sheet, which has high mechanical strength and shock resistance.

Tensile strength at break = 50 MPa;

Flexural strength = 70 MPa;

Ignition temperature> 400 ° С;

Heat resistance = 82 ° С;

Cold and hot ductility;

Thermoforming temperature 120-160 ° C.

In terms of their performance, the reflective screen and its components are made on a well-known equipment park using modern technologies.

Assembling the reflective screen: in the front panel 3 (Fig. 1) along the bend line 9 (Fig. 3), sides 5 are formed at an angle of 35 ° with a width of 16 mm and grooves 10 (Fig. 3) for positioning the hooks 8 located in the stiffeners: in two fastening strips 1 passing into stiffeners (Fig. 1), in the plane of which there are grooves-hooks 8 (Fig. 2) and in the stiffener 2 (Fig. 2) a reflective screen installed in the center due to the position lock 7 (Fig. . 2) entering hole 6.

To adjust the length of the reflective screen, in the front panel 3 (Fig. 1) for two fastening strips with stiffening ribs and position latches, three holes are provided, located on the center line of the front panel. Thus, the stiffeners are installed on the front panel of the screen on the sides through the grooves-hooks and through the position latches along the line of the center of the front panel, providing a radius of curvature of the segment of 257 ± 2 mm.

The assembled reflective screen is installed under the wall air conditioner 13, placing it on two hooks in the lower holes 4 (Fig. 2, Fig. 4) of the fastening strips 1. When the reflective screen is finally installed, the hooks must enter the upper holes 4 of the fastening strips so that the angle between the tangent to the surface of the front panel stiffener and the surface of the vertical wall should be 60 ° (Fig. 4).

The overhead reflective screen together with the wall-mounted air conditioner works as follows: the flow of the cooled air stream 14 of the air conditioning system (not shown in Fig. 5), under the blowing action of the fan, enters the center of the front panel and changes its direction by 60 °, creating a scattering effect that provides the necessary air exchange in small rooms with a ceiling height of 2.5-2.63 m.

The increased angle of 60 ° of the direction of the air stream reduces drag, that is, improves aerodynamic characteristics. The structure with PET reinforcing ribs also ensures that there is no vibration, sufficient rigidity, and the transparent screen together with the air conditioner make up a single whole and do not affect the interior of the room as a whole.
