Description

[Detailed description of the invention] The present invention relates to a chamber-type air conditioner that arbitrarily changes and adjusts the air conditioning capacity of each block in a ceiling-type air conditioning system to distribute ideal air indoors. be.

BACKGROUND ART Recently, so-called ceiling chamber air conditioning systems have been developed that use the interior space of the ceiling as a ventilation path to supply cool and warm air indoors.

However, most of these are ceiling A as shown in the first diagram.
A heat exchange device B, in which various mechanisms such as a heat exchange coil and a blower are integrally incorporated, is suspended and fixed to the steel frame of the ceiling beam, and there are several intake and outlet ports F and F on the ceiling surface. Because of this development, the air blower was uneven and the air distribution in the room was unbalanced, and the air was distributed even to unnecessary areas, which was extremely uneconomical.

The present invention is intended to fundamentally solve the above-mentioned drawbacks, and has an air blower and a motor arranged facing each other on both sides of an appropriately shaped rectifier plate in the center of the interior of the container, and an air inlet. In this mechanism, a backflow prevention damper is attached to the side of the housing so that it can be opened and closed, and a microcomputer unit that is electrically connected to the sensor and motor is installed in the blowout air passage.
It is an object of the present invention to provide a ceiling chamber type air conditioner characterized in that the amount of air blown in a ventilation passage is automatically and freely adjusted.

A concrete example of the present invention will be described in detail below with reference to the drawings. An M-shaped rectifying plate 2 is arranged in the center of the housing 1, and a plurality of IC motors 4, 4 are arranged on both sides of the rectifying plate 2.
and blowers 3, 3 are arranged with their respective blowing ports 3', 3' facing each other.

In addition, an appropriately shaped outlet grill 5 is provided below the container casing 1.
A sensor 7 and a microcomputer unit 8 are respectively installed in the air blowing passage 6 and electrically connected to the motors 4, 4.

Air suction ports 9, 9 on both sides of the cabinet 1, filter 1
0, 10 and backflow prevention damper 1 inside.
1 and 11 are attached so that they can be opened and closed, respectively.

Although an M-shaped plate is used as the current plate 2 in the embodiment, it is also possible to use any shape such as a V-shape.

In the above structure, the present invention is used by installing it in several places on the ceiling A, and the air from the heat exchange device E installed on the other side of the ceiling space is blown to each ventilation mechanism through the ceiling space. .

Then, by energizing the motor 4 and operating the blower 3, the air blower is placed on the front side of the rectifying plate 2.
Air is blown into the room from the outlet grille 5 while being properly rectified.

In such a state, the blowing capacity is reduced by stopping the blower 3 on either side and closing the damper 11 at the same time.

Incidentally, when blowing air, the air volume according to the air conditioning capacity of each block can be selectively adjusted to any desired air volume using the sensor 7 and the IC motor 4.
Therefore, it is possible to easily obtain a very economical air distribution distribution, such as blowing a large amount of air to necessary areas in the room and a small amount of air to unnecessary areas.

Moreover, by installing the rectifying plate 2 between the motors 4 and 4 on both sides, it can be used not only for the rectifying effect but also as a silencing mechanism. It has the advantage that there is no need to install a sound deadening mechanism or the like, and the overall shape can be made very compact and lightweight.

Furthermore, since a plurality of motors 4, 4 are used, it goes without saying that even if one motor 4, 4 breaks down, sufficient operation can be obtained from the other motors 4.
