Description

[Detailed description of the invention] [Industrial application field]

[0001] This invention automatically adjusts the unbalanced distribution of cool and hot air in relatively large rooms such as factories, meeting places, hotels, and offices, and can always find the optimal natural environment for the room. This relates to a terminal type air conditioner.

[Conventional technology]

[0002] Normally, as a means of cooling and heating a wide area or multiple rooms, several air conditioners are installed at each necessary location, but recently, air conditioners are being used to supply the intake and return air of the room to a single unit. A so-called terminal type air conditioner is known in which the air conditioner is operated by a device.

[Problem to be solved by the invention]

[0003]However, since the above-mentioned mechanism always sends a constant amount of air, it is difficult to maintain an almost uniform temperature throughout the room, as the indoor temperature varies considerably depending on the location near the window, population density, etc. even in the same room. It had certain drawbacks.

[Means to solve the problem]

[0004] The present invention has focused on the above-mentioned drawbacks, and, for example, an air conditioner for interior air conditioning and perimeter air conditioning is integrated into an integrated structure, and air volume adjustment dampers provided in each of the in-flight ventilation passages are operated to perform warm-up operation according to the indoor environment. The main purpose of this system is to automatically and instantly adjust and supply optimal cooling and heating air to the area where it is needed.

[0005] The center of the fuselage is divided into left and right sides by a partition plate,
A U-shaped ventilation passage is formed in each of the left and right rooms, and necessary mechanisms such as pre- and main filters, air volume adjustment dampers, blowers, and drain pans, cold and hot water coils, and electric control valves are installed in each ventilation passage. It is an object of the present invention to provide a terminal type air conditioner characterized in that the upper ends of both sides of the U-shaped air passage are connected to an air intake port and an air outlet opening at the top of the machine body. .

[Effect]

[0006] Outside air and return air from inside the cabin are introduced into the cabin through the air intake ports provided at the top of the aircraft, filtered through filters installed in each ventilation passage, and then cooled and heat-exchanged to an appropriate temperature using hot water coils. Cool and warm air at different temperatures is simultaneously delivered to the interior and perimeter areas from the left and right air outlets. In addition, when blowing air, the air volume adjustment dampers installed on both sides of the room A and B are mutually operated to adjust the air volume individually, thereby delivering the desired air volume of cool and warm air to the necessary parts of the room connected to the air outlet. This makes it possible to easily and reliably supply air conditioning, thereby solving the conventional problem of imbalance in heating and cooling between rooms at once.

[0007] By interlocking the damper mechanism and the electric control valve mentioned above, the amount of water flowing to the coil can be automatically adjusted at the same time as the air volume is adjusted by the tamper operation, and it is also possible to instantly switch between cold and warm air. It may also be possible to easily obtain a more effective air conditioning supply.

【Example】

[0008] Hereinafter, embodiments will be explained with reference to the drawings.
Reference numeral 1 denotes a fuselage body, with the central part of the fuselage divided into left and right sides by a partition plate 2, with chambers A and B formed on both sides, and U-shaped ventilation passages 3, 3 inside the chambers A and B, respectively. A pre-filter 4 and a main filter 5 are provided above the ventilation passages 3 and 3, and air volume adjustment dampers 6 and 7 are provided between the ventilation passages 3 and 3, so that the passage can be freely opened and closed to adjust the air volume. At the same time, electric motors 8, 8 and blowers 9, 9 are installed below the U-shaped ventilation passages 3, 3, respectively. Furthermore, a cold water coil 10 is installed in the ventilation side passage of the U-shaped ventilation passages 3, 3.
, 10, heat exchange coils of the hot water coils 11, 11 are installed in appropriate positions such as vertically and horizontally or diagonally, and other drain pans 12 are installed.
, 12, the necessary mechanisms for the electric control valves 13, 13, such as electric two-way valves, are arranged. In addition, the electric control valves 13 and 13 are linked and connected to the air volume adjustment dampers 6 and 7 to automatically adjust opening and closing, and automatically perform operations such as adjusting the amount of water flowing to the coil, controlling opening and closing, and changing the switching of the heating and cooling passages. It is also possible to automatically adjust the amount of air intake and air blowing each time the indoor environment changes using a mechanism or computer. The upper ends of both sides of the U-shaped ventilation passages 3, 3 are connected to air intake ports 14, 14 and air supply ports 15, 15, which are opened at the top of the body 1, respectively. In addition, the above-mentioned intake ports 14, 14 may not be separately opened at the upper part of the aircraft body 1 in the intake portion of the U-shaped ventilation passages 3, 3 on both sides, but may be opened together as a single intake port as shown in the illustrated example. The filters 4 and 5 are also installed either singly or in combination to meet the above requirements, depending on the indoor environment, without making any distinction between blur and main filters.

[0009] In addition, in a room that requires a noise reduction function, an intake port 14 and an air supply port 15, 15 are provided above the U-shaped ventilation passages 3, 3, respectively, and an appropriate noise reduction mechanism is provided inside. The structure has a structure in which sound damping chambers 16 are integrally arranged. Although the above embodiment is a terminal air conditioner, it goes without saying that the above structure can be widely used in other air conditioners.

【Effect of the invention】

[0010] As described above, this invention divides the central part of the fuselage into left and right parts with a partition plate, and arranges various mechanisms such as filters, blowers, cooling and hot water coils in each room, and separates the air passages in the ventilation passages on both the left and right sides. It is an integral structure with a roughly U-shaped ventilation passage in which an air volume adjustment damper can be installed to freely adjust the air volume.By warming up by adjusting the damper, air can be distributed to various parts of the room from the air outlets on both sides of the upper part of the aircraft. This makes it possible to reliably and easily supply air at a temperature suitable for the environment. Incidentally, by operating the damper and processing using different filters as mentioned above, it is possible to simultaneously supply the optimal amount of cool air and air volume to the necessary areas such as the interior and perimeter areas of the room, or warm air, which have completely different conditions. This has the effect of completely solving the conventional environmental imbalance between rooms. Furthermore, by integrally forming multiple U-shaped ventilation passages, there is no need for multiple air conditioners, and the entire aircraft is extremely compact and simplified, making maintenance and other operations easier to perform from the front of the aircraft. It also has the following advantages.

Furthermore, as described in claim 2, the present invention is an optimal invention as a low-noise terminal type air conditioner that can simultaneously provide extremely quiet air conditioning by installing a noise reduction chamber in the upper part of the machine body. be.
