Description

The recirculation ventilation device preferably has a ceiling ceiling distributor

The subject of the invention is a recirculation ventilation device, preferably a ceiling-mounted ceiling distributor, which is used in distribution systems for air heating or cooling, ventilation primarily of living quarters.

The distribution system represents the connection of the recuperator to the air valve in the living space into which the air is sucked in or the air is taken in by separate systems. The recuperator is connected to a ceiling ceiling manifold by a pipe. Overhead ceilings

the manifold is connected to the air vent chambers by tubing. The air vent chambers are arranged in the living rooms on the ceiling on the walls or on the floor into which the air valves are inserted.

A technical problem solved by the invention is to improve the housing of the overhead ceiling manifold by reducing vibrations and noise and achieving a uniform flow rate for all outputs while minimizing the risk of bacterial air infections. A technical problem solved by the invention is to improve the protection of pipes against being pulled out of an overhead ceiling manifold.

There is a known solution for a ceiling-mounted ceiling manifold with a square-shaped housing with one large pipe connection and at least three pipe connections in one row and with several rows. Pipe fittings are arranged on a separate plate so that the plate can be attached to the housing such that the symmeters of the large pipe fitting and the pipe fittings are parallel or rectangular. A solid plate is attached to the opening. The material used to make the ceiling ceiling manifold is galvanized sheet metal. The casing of the case is made of several parts with rivets or screws. Pipe fittings, large pipe fittings are connected to the housing by rivets or screws. The inside of the case is lined with noise reduction materials.

To prevent the ribbed tube from being pulled out of the pipe fitting, a U-shaped guard is made. After inserting the ribbed pipe into the pipe fitting, the fuse is inserted into the slot of the pipe fitting to capture the narrower diameter of the ribbed pipe.

In R&D, it has been found that this solution causes high vibrations and noise at high air flow rates. Air measurements at individual pipe connections showed very different values.

In a similar solution, two sheet metal bulkheads were placed inside the enclosure, one from the bottom and one from the top of the enclosure. This solution also causes a large airflow •

always high vibrations and noise. Air measurements at individual pipe connections showed very different values, but minor variations.

The disadvantage lies in the composite construction of the housing, whose inherent oscillating frequency in the flow of air amplifies vibration and noise. The box-like housing causes turbulent air movement and high air flow resistance. The jointed joints of the composite structure, as noise-reducing liners, present a high risk for the development of various harmful biological substances. The metal structure is electrically charged with static electricity, which attracts particles from the air with the opposite charge.

Furthermore, the disadvantage of the U-shaped solution is that in the case of three types of hose connections, it is not possible to insert this lock in the same way for two types if it is close to the wall or ceiling.

According to the invention, an overhead ceiling manifold is constructed with a quad-shaped housing with a single large pipe connection with partitions spaced apart from one another at one bottom and one above the housing as an integral part of the single shell of the housing. The shell of the case is ribbed and circular side to side.

Furthermore, at least one bulkhead within the width of the housing changes the height of the bulkhead. The housing, full plate and hose plate are made of antistatic and antibacterial thermoplastic, presumably polyethylene.

According to the invention, the guard is made as a discontinuous elastic ring with two tiles, which in the middle pass into a semicircle and rounded on one side with a sharp edge on the other. The material used is a thermoplastic with high elastic capacity.

The quad-shaped ceiling divider with bulkheads and finned shell represents a compact construction that significantly reduces vibration and noise at high airflows. By adjusting the slope of the walls of the barriers, the flow resistance is reduced. With the additional intervention of changing the height of the barrier and the addition of a smaller barrier, measurements of the air at the individual pipe connections showed a steady flow with smaller deviations. No noise reduction liners are required. The fabrication material used prevents the development of various harmful biological substances. There are no particles resulting from static electricity.

The retainer according to the invention is inserted into the hose connection before mounting an overhead ceiling bracket with a sharp edge to the housing. The notch in the pipe connection allows the passage of the tile to be waved into the pipe connection so that the semicircle of the tile extends beyond the inner diameter of the pipe connection, the rest of the tile is inside the cut pipe connection.

After mounting the overhead ceiling bracket, ribbed tubes are inserted. The movement of the tube in the direction of the housing due to the circumferentially formed edge of the semicircular plate deflection permits the elastic ring to be moved outwards. In the space between the ribs of the pipe, the guard snaps. The sharp edge of the semicircular tile does not allow the elastic ring to move outwards when the pipe is pulled out. If you want to pull out the tube, use a screwdriver to remove the elastic ring.

The invention will be described in the embodiment and in the drawings, which illustrate Fig. 1 Floor-mounted ceiling manifold Fig. 2 Floor-mounted ceiling manifold cross-section I-I Fig. 3 Surface-mounted ceiling manifold cross-section II-II Fig. 4

FIG. 1 illustrates an overhead ceiling distributor with a quad-shaped housing with a large tubular connection 6 with a fixed full plate 5 and a plate with tubular connections 2 with at least three tubular connections 3 in a row and in several rows. Fuses are fitted to the pipe connections. The shell of the housing 1 is ribbed with side to side circular crossings.

In FIG. 2 shows an overhead ceiling divider in section I-I. The bottom partition 7 is mounted in the housings from below and offset from them by the upper partition 8 above, as an integral part of the uniform shell of the housing in the width of the housing 1. The walls of the partitions 7, 8 are made obliquely and connected in a semicircular manner above. The width and height of the bulkhead 7, 8 as the distance from one another depends on the desired amount of air flow. The width and height of the bulkhead 7, 8 is about about half the height of the housing 1. For several types of pipe connections 3, a small barrier 9 may be installed below the housing 1 in front of the pipe connection plate 2.

The housing 1, the full plate 5 and the plate with pipe connections 2 are made of antistatic and antibacterial thermoplastic, presumably polyethylene.

In FIG. 3 shows an overhead ceiling divider in section II-II. The height of the upper barrier 8 is at the sides of the housing H min in the center of the housing is H max and the difference can be up to 30%.

FIGS. 4 and 5 show a retainer 4 made as a discontinuous elastic ring with two tiles, which in the middle pass into a semicircle and rounded on one side with a sharp edge on the other side. The fabrication material used is a thermoplastic with high elastic capacity.
