Description

[Detailed description of the invention] The present invention provides a U-shaped ventilation passage inside the aircraft body, and arranges various mechanisms such as a filter, a heat exchanger, a control valve, and a humidifier in the U-shaped ventilation passage. In this high static pressure air conditioner, the intake and return air opening blocks at each of the upper ventilation openings of the U-shaped ventilation passage can be turned in any direction or divided, and can be installed in any narrow space. The purpose is to provide an air conditioner that has a compact overall shape, low noise, and is energy saving.

Normally, an air conditioner has a heat exchange coil and a blower arranged in tandem in the air passage inside the vertically elongated body, so there is less space for installing other related mechanisms such as a filter silencer, eliminator, humidifier, etc. Therefore, even if these devices are installed outside the machine or in the air duct, the overall shape becomes very bulky, and the air inlet and return port communicating with the air duct become very bulky. Due to the above structure, air vents, air outlet ports, etc.
Since it is fixed to a part of the upper surface or a different side of the fuselage and has an attached opening, it is not only limited in its installation location, but also has drawbacks such as causing a significant hindrance to the duct piping.

In order to solve this drawback, the inventor first proposed the idea of Utility Model Application No. 58-59692, as shown in Figure 1, that is, U-shaped ventilation passages 3, 3' were provided in the center of the interior of the fuselage 1 through the partition plate 2. Forming and providing the U-shaped ventilation passage 3,
A heat exchanger 4 is arranged in one side of the air passage 3', and a blower 5 is arranged in the air passage 3' on the other side, and various mechanisms such as a humidifier, a main and sub-filter of a noise reduction mechanism are arranged in the U-shaped air passages 3 and 3'. The air conditioner has been developed to have an extremely compact overall shape and an air inlet 12 and an air outlet 13 in the upper part of the body 1, and has been very well received in the industry.

The purpose of the present invention is to enable the air conditioner described above to be easily installed in any narrow space, such as a room in a building valley, and to expect more effective and efficient effects. Generally, a U-shaped ventilation passage is formed inside the aircraft body, mechanisms such as a heat exchanger, a humidifier, a filter, etc. are arranged in the U-shaped ventilation passage, and the air is supplied to the upper part of the U-shaped ventilation passage. The present invention relates to a high static pressure air conditioner having return air ports each having openings, and wherein several fan blocks are installed on the left and right sides of the upper part of the air conditioner so that the air supply direction can be freely changed.

Hereinafter, the embodiments of the present invention will be explained in detail with reference to the drawings illustrating the embodiments of the present invention. As mentioned above, the internal structure of the main body includes a U-shaped ventilation passage 3 located in the center of the interior of the aircraft body 1 with a partition plate 2 interposed therebetween.
3' is formed, and one passage 3 of the U-shaped ventilation passage is provided.
A heat exchanger 4, a humidifier 5, and a control valve 6 are disposed within the U-shaped ventilation passage 3', and various mechanisms such as a medium-performance or Hepa filter 7 and an autoroll filter 8 are disposed within the other side ventilation passage 3'. 3, 3 are arranged in parallel on the upper part of the fuselage 1 and opened. Air intake port 12 and air supply port 13
communicate with each other.

Note that the locations of the various mechanisms described above are not particularly limited and can be arbitrarily arranged depending on the model and the like.

The reference numeral 9 in the drawing indicates a drain pan.

The present invention is based on the air conditioner as described above, and a blower F is installed inside the air inlet 12 and the air outlet 13 which are opened at the upper part of the airframe 1 so that the suction direction can be changed freely. When installed, there is 1 air outlet on one side.
Fan blocks A and B each having an open air outlet 10 or a suction port 11 are installed in any direction depending on the installation location, purpose, etc., and the air outlet 10 and suction port 11 are connected to the duct D.

The blower F is optimally a subrye blower or a retan blower for intake and return air, and symbol M is an electric motor and F is a driving electric motor.

The present invention has the above-mentioned configuration, and by changing combinations of the airframe 1 and fan blocks A and B, it is possible to easily obtain an air conditioner with freely adjustable directionality.

The problem is that in the configuration shown in Figure 2, air is sucked in from the top and recirculated to the top through A-1-B. In addition, by arranging the space blocks A' and B' in parallel as shown in Figures 5 and 6, air can be easily sucked in from quite far away on the side of the aircraft, and the air can be exhausted over long distances. Furthermore, as shown in Figure 7, a duct D can be connected between the fan blocks A and A and B and B, or each of the fan blocks A and B and the space blocks A' and B' can be suspended from the ceiling. By connecting these with ducts D of various lengths and shapes as shown in FIGS. 8, 9, and 10, air can be easily received from any location.
This allows air to be easily and reliably blown in any direction.

Furthermore, in the case where the static pressure is low, it may be possible to use a mechanism such as a filter or a muffler instead of the blower F on one side of the fan blocks A and B.

In the present invention, the directionality can be freely changed by changing the arrangement of the fan blocks A, B and the duct D, and can be easily changed. It has the advantage of being able to supply air and install the aircraft.

Furthermore, in the case of high static pressure type blowers, air foil fans, turbo fans, etc., which are relatively noisy due to their large shape and weight, have been generally used, but in the present invention, divided fan blocks A and B are used. Since the machine uses a small blower divided into a forced blower and a blowout blower, the main body of the machine is very compact, which not only saves energy, but also increases efficiency by increasing the number of blowers. It has effects such as low noise.

Furthermore, due to the arrangement of the fan blocks, it is easy to change from a vertical type to a horizontal type, and the overall shape can be made very compact.
