Abstract

PURPOSE:To make a unit structurally compact as a whole and enable attaching it to a ceiling or the like in a simple manner by joining as an integral unit a body consisting of a heat- exchange chamber provided at an air inlet in the front with an air flow-controlling device capable of freely changing the flow of air and another body placed at the front of the other body and consisting of an air-intake chamber having air inlets in the front, in a side, in the top or in the bottom as befits the case. CONSTITUTION:Between the front part of a heat-exchange chamber B and an air-intake chamber A there are provided a partition 5 and air inlets 4 to the heat-exchange chamber B at the right and at the left. At the opening of each of the air inlets there is provided an air flow-controlling device 6 designed to be freely opened and closed or removed so as to function to control the amount of the air passing through the air inlet 4. The air flow- controlling device 6 consists of an ordinary damper mechanism is which a motor 12 moves a movable plate to the right or left or upward or downward in controlling the opening. An alternative method is to form a multiplicity of orifices as air holes in the air inlet 4 and, by mutually moving an air flow-controlling plate and a movable plate in a manner of sliding, the amount of the air passing through the air holes is changed. Air supply holes 11 are opened, for example, in the rear, in a side, or in the bottom of the body 1 of the unit as required, and cooling or heating air is distributed to rooms directly or through ducts C.

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 indoors 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 delivering cool and hot air to many rooms in a building, such as an office or a hotel. There was a problem with quiet indoor installation due to the combination of air supply noise and other noise. In addition, recently, the heat exchange processing side unit and the above-mentioned ventilation side unit are formed separately and connected by a duct, so-called.
Separate air-conditioning rock structures have been developed, but since the air volume adjustment device, that is, the damper mechanism, is installed in a narrow space such as the ceiling, maintenance and other operations are difficult. It was inevitable that the installation location would be subject to considerable restrictions.

[The problem that the invention attempts to solve]

In view of the above drawbacks, the present invention provides air that has already been heat treated,
Alternatively, the air from the blower unit side is sent to each room, and even though the amount of air blown from the blower side is constant, it is ideal for the air condition of each room and is almost noiseless. This design aims to ensure reliable air conditioning deployment, and the overall design is compact, making it extremely easy to install in any location such as the ceiling, and in particular, making maintenance and other tasks easier. It is something to do.

[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 formed on the left and right sides using partition plates inside, and heat exchange coils are installed diagonally within the heat exchange chambers B, B. The front of the fuselage is constructed by arranging necessary mechanisms such as humidifiers and valves in each of the gaps, and installing a wind foot adjustment mechanism in the front intake ports of the heat exchange chambers B and H to freely adjust the air volume. It is an object of the present invention to generally provide a ceiling-suspended air conditioning unit characterized in that an air intake chamber is integrally connected with an air intake chamber having an air inlet opening at an appropriate location such as the front, side, top or bottom.

Another feature of the aircraft is that a silencer component is disposed in the intake chamber connected to the front of the fuselage, so that the intake chamber can also be used as a noise reduction chamber.

[For production]

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

In addition, by arranging an appropriate silencing mechanism in the intake chamber, it can also function as a high-performance silencing 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 numerals A indicate air intake ports (3) and (3) located at arbitrary locations such as the front and sides.
) is integrally connected to the front part of the fuselage (1) through an intake chamber having an opening.

B is a heat exchange chamber formed by dividing the center of the fuselage (11 into left and right sides by a partition plate (2), and heat exchange coils (8), (8) are arranged in an inclined manner in each chamber. At the same time, humidifiers (7), (7), operation valves (9), (9) are placed in the space, and a drain pan 001αO, etc. are placed in the bottom part.

In addition, a partition plate (5) is provided between the heat exchange chambers B, the front part of B and the intake chamber A, and left and right intake ports (4), (4) communicating with the heat exchange chamber B1B are opened, respectively. The air volume adjustment mechanisms (6), (6) are provided in the air intake openings in a manner that they can be opened, closed, and removed to increase or decrease the air volume that passes through the air intake ports (4), (4).

The above air volume adjustment mechanisms (6) and (6) are ordinary damper devices in which a movable plate is opened and closed left and right or up and down by an electric motor, and a large number of ventilation holes are opened in the intake ports (4) and (4). Any means can be used, such as sliding the perforated air volume adjustment plate and the movable plate relative to each other to increase or decrease the amount of air coming from the ventilation holes.

In addition, air inlets αn and ab can be opened at necessary locations such as the rear, sides, and bottom of the above-mentioned body (1), and air can be directly or directly installed. and C are connected to deliver cooled and heated air to each room.

Inspection panels a and b are attached to the body (1) and the intake chamber A on the sides, bottom, etc., 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, member, etc. of an appropriate structure is disposed in the above-mentioned intake chamber A, and the intake chamber If A is also used as a silencing chamber, a more effective and high-performance silencing function can be expected.

Furthermore, it is also famous that a high-performance filter is directly connected to the above mechanism.

〔Effect of the invention〕

As described above, the present invention connects the intake chamber A integrally to the front part, and separates the heat exchange chambers B to the left and right by the partition plate (2) in the center of the machine body (1), and forms the air intake port inside the machine. (4), (
By forming the two-type unit structure in which the air volume adjustment mechanisms (6) and (6) are attached to the part 4) in an open/close manner so as to freely adjust the air volume, the following effects are achieved.

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

(Maintenance and other work can be performed extremely easily and reliably by simply opening and closing the inspection panels attached to each side of the 13 aircraft, making it especially easy to work in confined spaces such as ceilings, which were previously difficult.) Moreover, it is possible to carry out maintenance for two machines at the same time.

(Since air inlets on each side of the intake chamber or air supply ports are provided at appropriate locations on the aircraft body according to the design, the direction of the duct C1C on the outflow side can be arbitrarily determined. These can be easily installed.

υ 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. This has the advantage that maintenance holes can be obtained naturally and freely.

■ Conventionally, the air volume adjustment mechanism that was placed inside the duct is integrated with the heat exchange coil inside the machine, which simplifies inspection and repair work, especially from the air inlet. The same air volume is installed at each heat exchange room entrance.
By operating the 114 adjustment mechanism, it is possible to supply completely different air volumes to each room, and by closing the damper on one side where it is not needed and opening only one side, it is possible to supply air to the room where it is needed. It is extremely economical as it only supplies a predetermined amount of cooled and heated air.

Moreover, by removing the air volume adjustment mechanism, it is easier to perform mincing work inside the machine, and furthermore, even when the duct is connected, cool and warm air that has undergone heat exchange inside or near the room is sent. It has economical effects such as minimal heat loss during transportation.

[F] Since the blower, which was traditionally a cause of noise generation, is located outside the machine, there is no concern that such noise will leak into the room, and the intake chamber has been replaced with a high-performance noise reduction chamber. By being used as a double blower, almost noiseless air blowing conditions can be obtained, making it ideal for hospitals, hotels, research institutes, etc.

Although the present invention was invented as a ceiling-mounted air conditioning unit, it goes without saying that the air-conditioning unit of the present invention may be widely used not only for floor-standing types but also for all other types of air conditioners. Nor.
