Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention seeks to provide air conditioning management that is optimal for each room's air conditions in buildings and other multi-unit buildings that have a large number of rooms. A separate type air conditioning unit on the air processing side used in an air conditioning system that is expected to produce ultra-noise air conditioning.

[Conventional technology]

However, since these units are blowing air directly by a fan, the rotation noise of the fan,
There was a concern that the air would leak into the room due to air leakage.

Especially in recent years, with the rapid development of the air conditioning industry, advanced technology is required both functionally and mechanically, and in order to satisfy all these conditions, it is difficult to Even if you try to completely eliminate the necessary vibration noise, it is extremely difficult to install fairly complicated equipment such as a noise reduction mechanism in a limited aircraft, and furthermore, it is impossible to avoid reducing the air volume capacity etc. It is inevitable.

[Problem to be solved by the invention]

In view of the above-mentioned problems, the present invention provides an air conditioning unit that incorporates a heat exchange coil and an air volume adjustment mechanism on the indoor side, and provides air processing that enables air conditioning to be developed under optimal conditions for each room. Regarding the side air conditioning unit, the main challenge is to find an ultra-low-noise air conditioning device that can simplify the equipment contents and make the overall shape extremely compact as well as functional.

[Means to solve the problem]

As a means for achieving the above object, the present invention provides a substantially U-shaped ventilation passage (
2), a ventilation passage ■ that communicates the return air port and the outdoor exhaust port, and a damper mechanism is provided between both ventilation passages (2) and 0 to freely switch and send the airflow in the ventilation passage ■. Each bypass ventilation passage (0) is provided with a mechanism such as a total heat exchanger, a ventilation fan, etc. in each of the above-mentioned ventilation passages (2), and a return air fan, etc. in the ventilation passage 0. , a separate space unit consisting of each required mechanical member,
The aim is to provide a wide range of services.

[For production]

1 m'N of fresh air taken in from the outside air intake (1)
'tckA'%, the air passes through the total heat exchanger (5) and is exchanged with heat to an appropriate temperature, while the air supply fan (6) operates to send the air through the air supply port (2) into a duct (not shown). Air is distributed to each coil unit χ (not shown) arranged on the indoor side.

In addition, at the same time as the above operation, the contaminated air inside the room flows through a duct (not shown) into the ventilation passage ω from the return air port (3), and is exhausted outside from the exhaust port (4), but all heat is exchanged in the process. Flow through the vessel (5).

In such a body, a part of the outdoor exhaust air mixes with the outside air flowing through the above-mentioned ventilation passageway (6) by the operation of the damper mechanism in the bypass ventilation passageway (0), resulting in the optimum amount of air required for heat exchange. It is heated to a certain temperature, and the air is returned to the room through the air supply port (2).

In other words, it is an attempt to significantly reduce the amount of heat used by effectively utilizing the residual humidity at room temperature in the contaminated air, which has conventionally been completely exhausted.

The heat-treated cooled air is sent to the fan unit, where it is exchanged with heat to an appropriate temperature by the heat exchange coil inside the fan unit, and the air volume is adjusted to an appropriate air volume by the air volume adjustment device. Each room is supplied directly.

〔Example〕

Hereinafter, embodiments of the present invention will be explained in detail with reference to illustrative drawings. At the top of the aircraft, there is an outside air intake (1), an indoor air supply port (2),
A return air port (3) and an outdoor exhaust port (4) are provided at each opening, and the outdoor air intake port (1) and the indoor air supply port (2) are communicated to form a substantially U-shaped ventilation passage (2). If necessary, arrange mechanisms such as a total heat exchanger (5), an air supply fan (6), an electric motor (7), a control device (8), a silencing mechanism (9), and a main filter 〇〇 in the passage. Along with the above ventilation passage (2)
A ventilation passage ■ connecting the return air port (3) and the exhaust port (4) for indoor air is formed in the air passage. A bypass ventilation passage (C) is formed between the above-mentioned ventilation passages (2) and 0, and all or part of the recirculated air from the indoor side is exhausted into the ventilation passage 0. A switching damper mechanism □□□ is arranged in the ventilation passageway (6) for bypass return.

An air conditioning unit with such a structure is placed indoors, underground, on the roof, or outdoors as an air processing unit, and is connected by duct to a coil unit with an air volume adjustment mechanism installed on the blowing side installed in each room. The purpose of the system is to supply and distribute hot and cold air.

In addition, the above-mentioned silencing mechanism (9), main pre-filter (
10'), αO may be installed outside the machine in some cases without being placed inside each ventilation passage.

However, it can also be used alone as a fan unit or heat treatment air conditioner.

Furthermore, an appropriate noise reduction mechanism is installed inside the aircraft, and an outside air intake (
1) A mold surface formed by opening air supply/exhaust ports such as the indoor air supply port (2) may be integrally connected to the upper part or the back of the above-mentioned body as the noise reduction chamber 0.

[People 60] As described above, the separate type air conditioning unit according to the present invention is formed with the above structure, and by forming the ventilation passages in the front and back in a substantially U-shape, the ventilation passages are lengthened, and various types of air conditioning units can be used. Mechanism members can be easily placed in appropriate locations,
This has the advantage that the overall shape can be made extremely compact, and that various operations such as maintenance can be easily and reliably performed simply by opening the front door.

Further, by integrally connecting the chamber [F] with a built-in noise reduction mechanism to the aircraft body as described in claim 0, even more noise reduction effect can be obtained as a super noise reduction chamber, and it can be used in hotels, hospitals, research institutes, etc. This is the perfect completely low-noise air conditioner.
