Description

Variable diffuser unit for cooling / heating in air conditioning systems

The present invention relates to a diffuser device that is variable according to cooling / heating in an air conditioning system, and more particularly, is installed at the end of the duct in the air conditioning system so that the air drawn into the room flows in a horizontal direction during cooling, and is heated. The present invention relates to a diffuser device capable of achieving an optimal indoor environment by allowing air taken out into the room to flow in a vertical direction.

In the building air conditioning system, air is blown out into the indoor space with a certain amount of airflow and wind speed to perform cooling and heating of the indoor space. In such an air conditioning system, the air outlet (ventilating hole) is ceiling or floor so that the first heat exchanged (heated or cooled) air can be branched to each required point of the room through the duct so as to meet the indoor setting conditions when cooling and heating the indoor space. Install on.

The diffuser (also called a blower outlet or a blower opening) used for such a conventional air-conditioning system is fixedly installed in the center part which guides the direction of air flow. Therefore, the diffuser in the conventional air conditioning system is made of the air flow only in the horizontal direction. This result is not a big problem because it is preferable that the flow of air is in the horizontal direction when cooling, but during heating, warmed air due to the difference in specific gravity of the air gathers in the upper part of the room and shows a large temperature difference between the upper and lower parts of the room. . As a result, there is a problem that there is a limit in creating a comfortable indoor environment when heating using the air conditioning system.

Therefore, the present invention has been proposed to solve the problems of the prior art as described above, and an object of the present invention is to be installed at the end of the duct in the air conditioning system so that the air taken out to the room flows in the horizontal direction during cooling The present invention provides a diffuser device capable of achieving an optimal indoor environment by allowing air taken out into a room to flow in a vertical direction during heating.

The diffuser device according to the present invention is largely connected to the duct, the portion that is not interpolated in the duct is formed in the shape of a hat, the end portion opposite to the duct is bent in the vertical direction, at least in the up and down direction inside the portion interpolated in the duct The outer body (1, 2) is fixed to two or more connecting rings (7), the support and guide central axis (3) fixed in the vertical direction in the center of the duct, and the support and guide central axis (3) It is installed to be movable, the connecting pin 6 is installed on one side to be coupled to the connecting ring, a plurality of conical (shade-shaped) blades (5) of different sizes at positions opposite to the connecting pin (6) Made of a fixed air flow guide (4).

Looking at the structure of the diffuser according to the present invention having such a configuration in more detail with reference to the drawings as follows.

The outer body 2 is formed with a connecting portion 1 for connecting one end to the duct. The duct connecting portion 1 is inserted into the duct and fixedly installed. And, the other end of the outer body (2) is formed in the shape of a hat, the end portion is bent in the vertical direction. In addition, as shown in FIG. 3, a connecting ring 7 for hanging the connecting pin 6 formed at one end of the air flow guide 4 at a position opposite to each other is provided in the duct connecting part 1 in the vertical direction. At least two are installed. On the other hand, the connecting ring 7 is formed such that the air flow guide 4 is not rotatable.

The central axis 3 for supporting and guiding is fixedly installed at the center of the duct, to prevent the air flow guide 4 from being separated from the duct, and to facilitate this in the vertical movement of the air flow guide 4. Is installed. Of course, such a support and guide central axis 3 may not be installed if necessary.
