Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ceiling-mounted air conditioning unit that quietly supplies a desired amount of cooled or hot air into a room depending on the air condition in each room. It is something.

[Conventional technology]

Normally, a blower unit is installed in each room as a means of supplying cold and hot air to a large number of rooms such as offices and hotels in a building. There was a problem with quiet indoor installation due to the combination of air supply noise and other noise. Recently, a so-called separate air conditioning system has been developed in which the heat exchange processing side unit and the above-mentioned air blowing side unit are formed separately and connected through a duct, but the air volume adjustment device, that is, the damper mechanism is installed in a narrow space such as a ceiling. Because they are located in such locations, maintenance and other operations are difficult, and it is inevitable that they will be subject to considerable restrictions at these locations.

[Problem to be solved by the invention]

In view of the above-mentioned drawbacks, the present invention supplies already heat-treated air or air from the blower unit to each room, and even though the amount of air blown from the blower side is constant, The purpose is to ensure that air conditioning is installed indoors with almost no noise, optimally suited to the air conditions of each room, and the overall shape is compact, making it extremely easy to install in any location, such as on the ceiling. Of course, this also simplifies various tasks, especially maintenance.

[Means to solve the problem]

As a means for achieving the above object, the present invention provides a plurality of heat exchange chambers B, B on the left and right sides using partition plates inside.
A heat exchange coil is installed diagonally in the heat exchange chambers B and B, and a humidifier,
Necessary mechanisms such as valves are arranged, and an air volume adjustment mechanism is provided at the front air intake ports of the heat exchange chambers B and B so that the air intake ports can be opened and closed at the front of the fuselage. It is an object of the present invention to generally provide a ceiling-mounted air conditioning unit characterized by integrally connecting intake chambers with openings provided at appropriate locations such as the top and bottom.

Another feature is that a noise reduction mechanism or member is disposed within the intake chamber connected to the front of the fuselage, so that the intake chamber can also be used as a noise reduction chamber.

[Effect]

The present invention has the above mechanism, in which heat is recovered in an air treatment unit (not shown).
Air, or air sent from a normal blower unit, is introduced into the intake chamber A through the duct C, and an air volume adjustment mechanism installed in the intake chamber adjusts the air volume to the left or right, or to any other direction. Air is sent into the heat exchange room B on the side, heat is exchanged to a predetermined temperature in the heat exchange room B, and cooled and heated air at an appropriate temperature and air volume is sent to each room from the air outlet that opens at the rear or bottom of the aircraft. .

By arranging an appropriate noise reduction mechanism within the intake chamber, the intake chamber may function as a high performance noise reduction chamber.

The arrows in the figure indicate the intake and exit directions of air, respectively.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Reference numeral A denotes an intake chamber formed by opening air intake ports 3, 3 at arbitrary locations such as the front, side, etc. They are integrally connected.

B is a heat exchange chamber formed by separating the left and right sides of the center of the fuselage 1 by a partition plate 2. In each chamber, heat exchange coils 8, 8 are arranged in an oblique manner, and a humidifier 7 is installed in the space. , 7, operation valves 9, 9, and drain pans 10, 10, etc. are arranged at the bottom.

Further, a partition plate 5 is provided between the front parts of the heat exchange chambers B and B and the intake chamber A, and the heat exchange chambers B and B
Left and right intake ports 4, 4 communicating with the intake ports 4, 4 are opened respectively, and furthermore, air volume adjustment mechanisms 6, 6 are disposed in the intake port openings so that they can be opened, closed, and removed to increase or decrease the amount of air passing through the intake ports 4, 4. It has a function.

The above-mentioned air volume adjustment mechanisms 6, 6 are a normal damper device in which a movable plate is opened and closed horizontally or up and down by an electric motor 12, and an air volume adjustment plate that opens a large number of ventilation holes in the intake ports 4, 4. Any means can be used, such as sliding the movable plates relative to each other to adjust the amount of air flowing through the ventilation holes.

In addition, air supply ports 11, 11 are provided at necessary locations such as the rear, side, and bottom of the body 1, and cooled and heated air is delivered to each room either directly or by connecting to a duct O'.

Note that inspection panels a and b are attached to the sides, bottom, etc. of the fuselage 1 and the intake chamber A so as to be openable and closable depending on the design.

The present invention is constituted by the above-mentioned mechanism, and when noise reduction is particularly required, a noise-muffling mechanism, members, etc. of an appropriate structure are arranged in the above-mentioned intake chamber A, and the intake chamber A is If it is also used as a sound deadening chamber, a more effective and high performance sound deadening function can be expected.

Furthermore, it is also possible to directly connect a high-performance filter to the above mechanism.

〔Effect of the invention〕

As described above, the present invention has an intake chamber A in the front part.
are integrally connected, and the heat exchange chambers B and B are separated into left and right sides by a partition plate 2 in the center of the machine body 1, and air volume adjustment mechanisms 6, 6 are installed at the air intake ports 4, 4 in the machine so that the air volume can be adjusted freely. By forming the unit into a two-piece structure, the following effects can be achieved.

(A) Since there is only one main duct and main piping, the number of ducts used can be greatly reduced compared to the conventional multiple piping system, which has great economic benefits.

(B) Maintenance and other work can be performed extremely easily and reliably by simply opening and closing inspection panels attached to each side of the aircraft, making it especially possible to perform work in confined spaces such as the ceiling, which was previously difficult. It was easy. Furthermore, maintenance for two machines can be performed at the same time.

(C) Air intake ports on each side of intake chamber A or air supply ports are provided at appropriate locations on the fuselage according to the design, so the direction of the inlet and outlet ducts C and C' can be freely adjusted. These installation operations are easy.

(D) By installing the heat exchange coil obliquely in the heat exchange chamber, space for various mechanisms such as valves and humidifiers can be easily obtained, and the overall shape can be made extremely compact. Depending on the direction of diagonal installation, there are advantages such as a maintenance hole can be created naturally and freely.

(E) The air volume adjustment mechanism, which was conventionally placed inside the duct, is now integrated into the machine together with the heat exchange coil, which simplifies inspections, repairs, and other work. By operating an air volume adjustment mechanism that arranges the same air volume at the entrance of each heat exchange room, it is possible to supply completely different air volumes to each room.Furthermore, by closing the damper on one side where it is not needed, By opening only the opening, a predetermined amount of cooled air can be sent only to the indoor side where it is needed, which is very economical. Moreover, by removing the air volume adjustment mechanism, maintenance work inside the machine is easier, and even when the duct is connected, cooled and heated air that has undergone heat exchange inside or near the room can be supplied. Therefore, there are economical effects such as minimal heat loss during transportation.

(F) Since the blower, which was a source of noise in the past, is located outside the machine, there is no concern that such noise will leak into the cabin, and the intake chamber has been replaced with a high-performance noise-damping chamber. By using the air conditioner for both purposes, it is possible to achieve air blowing with almost no noise, making it ideal for hospitals, hotels, research institutes, etc.

Although the present invention was invented as a ceiling-mounted air conditioning unit, it should be noted that in some cases, the air-conditioning unit of the present invention can be widely used not only for floor-standing types but also for all other types of air conditioners. Not even.
