Description

[Detailed Description of the Invention] The present invention relates to an air conditioner that integrates an air supply port, a return air port, an exhaust port, and a suction port so that the overall shape can be made extremely compact.

Conventionally, air conditioners that are buried in the ceilings of hotels, hospitals, buildings, offices, etc., for example, are fan coil type, in which mechanisms such as a heat exchanger and blower are integrated into the air conditioner. As a result, various problems have arisen, including not only water leakage, but also noise caused by the blower and drainage disposal methods. In addition, the central duct system has the advantage of solving all of the above-mentioned drawbacks, but on the other hand, the air supply, return, and exhaust ports must be installed separately, and the air volume increases. Since each mechanism such as an adjustment damper, a sound-deadening chamber, and a branching chamber is required, the overall shape tends to become large, which not only makes it difficult to install in a narrow ceiling, but also requires an inspection opening. There were drawbacks such as the necessary cleaning and inspection work, which was extremely difficult.

In view of these shortcomings, the present invention attempts to provide an air conditioner that is highly efficient and has a compact overall shape and no noise concerns. The air supply chamber A and the return air chamber B are divided into two through a partition plate, and an air supply duct is connected to the air supply chamber A side and a return air duct is connected to the return air chamber B side, and the air supply duct is connected to the air supply chamber A and return air chamber B. An air volume adjustment damper is placed in the return air duct, a silencing mechanism is installed inside the air supply chamber A, and a blow-out duct is connected, and a suction port that also serves as an inspection port is provided in a part of the return air chamber B. This air conditioner is characterized by:

Hereinafter, the structure of an embodiment of the present invention will be explained in detail with reference to illustrative drawings. 1 is a fuselage main body whose internal center is divided into two by a partition plate 2 into an air supply chamber A and a return air chamber B, one of which is the air supply chamber A. A long cylindrical supply air duct 3 communicating with the outside is opened and a short cylindrical return air duct 4 is opened and connected in the other return air chamber B.

A noise reduction mechanism 5 is disposed within the air supply chamber A, and a blow-off duct 6 of an appropriate length is connected to the end of the air supply chamber A to communicate with a blow-off port 7 inside the room.

In addition, the bottom surface of the aircraft 1 in the return air chamber B, or the side of the wing,
An inspection opening/suction opening 8 into which a pre-filter 8' can be fitted is provided at an appropriate location on the back, etc., and a lid door 9 is attached to the opening.
Attach it so that it can be opened and closed freely.

Further, manual or electric air volume adjustment dampers 10 and 11 are installed near the openings of the supply air duct 3 and the return air duct 4, respectively, to adjust the return and supply air volumes.

In some cases, it is also possible to provide an outside air duct within the air supply chamber A.

As described above, the present invention divides the interior of the aircraft body 1 into two by the partition plate 2 into the supply air chamber A and the return air chamber B, and on the other hand, air from the indoor side to be sucked up from the suction port 8 is transferred to the return air chamber B. At the same time as exhausting outside through the duct 4, fresh air from the outside is introduced into the air supply duct 3 and the air supply room A,
Furthermore, the air is completely silenced by the noise reduction mechanism 5 while being distributed in a predetermined manner into the room from the air outlet 7, so that the functions of outside air, return air, and supply air are performed simultaneously in one machine. This method makes it possible to easily supply completely still air into the room, and there is no need to install separate air supply, return, and exhaust ports as in the past. Since various mechanisms such as the air volume adjustment damper and the noise reduction chamber are integrated into the fuselage 1 rather than outside the machine, the overall shape can of course be made very compact, and especially with this invention The supply ducts of each are on different sides,
Or, it is completely different from the structure in which the air supply duct 3 is installed on the same side. Since both supply and return ducts are integrally installed on one side of the fuselage 1, it is extremely compact and provides good performance. This has the advantage that various operations such as cleaning, inspection, and repair can be performed from below the fuselage 1 very easily and easily by opening and closing the lid 9 attached to the fuselage.

The air conditioner according to the present invention can be used in various types without changing the above-mentioned structure, such as a ceiling-exposed type that is suspended from the ceiling, or a floor-standing type that is vertically installed on the floor. It can be used widely.
