Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention attempts to supply air conditioning with the optimum air volume and capacity indoors without changing the air volume from the blower at all. The present invention relates to an air conditioning unit equipped with an air volume capacity adjustment device that simultaneously distributes cooling and heating air with appropriate air volume and capacity even under different air conditions such as on the interior side and the perimeter side of a car.

[Conventional technology]

Normally, when seeking air conditioning with the appropriate air volume and capacity for a room, the air volume was adjusted by changing the rotation speed of the fan using a device such as an inverter. There was always an imbalance due to the indoor environment such as personnel, etc., and each time it was necessary to make adjustments and changes as described above.

However, repeatedly adjusting and changing the rotation of the fan creates a sudden load on the fan and related mechanisms due to the starting power, which of course significantly shortens the life of the fan. It also had the disadvantage of consuming a significant amount of electricity.

Furthermore, installing various mechanisms such as an inverter in the fan mechanism makes the structure extremely diversified and complicated, causing various failures and making maintenance work extremely difficult.

[Problem to be solved by the invention]

In view of the above-mentioned drawbacks, the present invention has been developed to improve the rotation speed of the blower,
It is possible to very easily adjust the air conditioning distribution of the air volume capacity that is optimal for the indoor environment at all times even though the air volume is constant without changing the air volume at all, and it is possible to improve the interior design, which has been a problem in the past. The main purpose is to simultaneously deploy air conditioning that satisfies each condition even in locations with different air conditions, such as side and perimeter sides.

[Means to solve the problem]

As a means for achieving the above object, the present invention divides the interior of the fuselage 1 into an intake chamber A on one side and a heat exchange chamber B on the other side by a partition plate 2, and forms a U-shaped ventilation passage in the interior of the machine. A vent 3 is provided between chambers A and B, and a heat exchange coil 4 is placed vertically in the opening of the vent 3, and an air volume adjustment plate 5 is provided in the opening of the vent 3 in front of the heat exchange coil 4. It is characterized in that it is arranged so that it can be opened and closed vertically or horizontally by a power mechanism 6 or the like, and the amount of air from the intake chamber A can be arbitrarily and automatically changed and adjusted to feed the air into the room.

Further, in the above configuration, as described in claims 2 and 3, heat exchange chambers B, B are formed adjacently on both sides of the intake chamber A, and heat exchange coils are provided in the respective heat exchange chambers B, B. 4, 4 are arranged vertically and in an inclined manner, and air volume adjusting plates 5, 5 are movable to open and close vertically or horizontally by a power mechanism 6 or the like in the vents 3, 3 that open below the intake chamber A. The cooling and heating air is simultaneously supplied into the heat exchange chambers B on both sides with the same or different air volumes and capacities through the opening and closing body formed by the above-mentioned both side adjustment plates 5, 5. It is also characterized by the fact that

[Effect]

Next, to explain the effect of the above configuration, for example, air from a fan unit with a total heat exchanger installed outside the machine flows into the intake chamber A inside the device through a duct etc. The heat is exchanged to an appropriate temperature by the heat exchange coil 4, and then supplied to the indoor side.In order to obtain the air conditioning required for indoor air conditions, etc., an air volume adjustment plate 5 is attached to the opening of the vent 3. By opening and closing the air vent 3, the amount of air passing through the vent 3 changes depending on the opening state, and the amount of air supplied to the heat exchange coil 4 is adjusted.

That is, the amount of air passing through the heat exchange coils 4 arranged in tandem is changed each time such as high, medium, small, etc., and the air distribution of the air amount and capacity required on the indoor side is easily determined by changing the amount of air passing through the coils. It is possible.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. A vent hole 3 substantially equivalent to the surface of the heat exchange coil 4 is opened in the heat exchanger coil 4 to form a U-shaped ventilation passage communicating the two chambers in the machine.

The heat exchange coils 4 mentioned above are arranged in tandem at the opening of the vent 3, and as a heat medium, not only cold and hot water but also direct expansion gas from a refrigerator is used.
A and b are the inlet and outlet pipes for the cold and hot water.

In addition, various devices such as a humidifier 11, a filter 12, a drain pan 13, etc. are appropriately arranged in the heat exchange chamber B as necessary.

In the above configuration, the present invention is configured such that the air volume adjusting plate 5 formed in a plate shape, a shutter shape, a winding type, etc. at the opening of the vent 3 on the front surface of the heat exchange coil 4 is movable to open and close in a sliding manner in the vertical or front-back direction. It can be freely arranged, and the amount of air given to the heat exchange coil 4 from the vent 3 can be arbitrarily large, medium, or small by opening and closing, and the air volume and heat exchange capacity can be adjusted very easily. It can be done.

Note that a manual method is also possible as a means for opening and closing the air volume adjusting plate 5, but it is also possible to use a power mechanism 6 such as an electric motor, mechanical force, or short circuit in conjunction with an air volume sensor sensing device, etc. to automatically open and close the air volume adjustment plate 5. This is also something to consider.

The above structure is the same regardless of the floor-standing type, ceiling-mounted type, or ceiling-embedded type.
Only a part of it is shown in the drawing.

Further, as shown in the third figure, heat exchange chambers B, B are formed on both sides of the intake chamber A via partition plates 2, 2, and ventilation ports 3, which are opened below the partition plates 2, 2, respectively. Similarly to the above, the air volume adjustment plate 5 is placed in the opening of 3.
5 are arranged to be movable up and down, and depending on the opening/closing operation range of these air volume adjustment plates 5, 5, the air volume capacity can be adjusted in each heat exchange chamber B, B without having the same air volume on the receiving side. Therefore, it is possible to simultaneously supply different amounts of air.

Further, by alternately and continuously opening and closing the air volume adjusting plates 5, 5, it is possible to easily bring wave air into the room.

Further, as shown in Figure 4, a heat exchange coil 4 is arranged vertically in one heat exchange chamber B formed on both sides of the intake chamber A, and a heat exchange coil 4' is arranged in an inclined manner in the other heat exchange chamber B. However, when the air volume adjusting plates 5, 5 have the same opening area on both sides, even though the air volume in both heat exchange chambers B, B is the same, the heat exchange capacity is different and the effect column below is suitable for indoor conditions. Therefore, it is possible to easily obtain the effective air conditioning deployment described in .

In addition, in areas where ultra-low noise is required due to the indoor environment, a noise reduction chamber 10 having an internal noise reduction mechanism 7 is connected to the inlet 8 and air outlet 9 portions of the aircraft body 1, thereby achieving a noise-proofing effect. further valid.

Note that the air guide path from the intake chamber A is not limited to the direction of the arrow in the illustrated example, and the air may be guided from below or from the back of the fuselage 1.

It goes without saying that the above mechanism can be widely used in any other air conditioner.

〔effect〕

As described above, the present invention provides a vent 3 at the bottom of the U-shaped ventilation passage and below the partition plate 2, and a heat exchange coil 4 is arranged vertically in the opening 3, and the heat exchange coil 4 is placed in front of the heat exchange coil 4. Since the air volume adjustment plate 5 is installed in such a way that it can be opened and closed, there is no need for a complicated air volume adjustment device as in the past, and the structure is simple and there is no fear of failure, and the fan rotation speed can be adjusted. This invention is said to be of great benefit as it allows you to easily determine the air conditioning system with the optimal air volume capacity for each room without making any changes.

In particular, according to the present invention, by adopting the configuration as set forth in claim 2, it is possible to simultaneously supply cold and hot air having different air volume capacities in a plurality of directions very simply and easily.

Further, as in claim 3, heat exchange coils 4 are arranged in tandem in one heat exchange chamber B, and heat exchange coils 4 are arranged in an oblique manner in the other heat exchange chamber B, with the vertical coil side facing indoors. By configuring the diagonal side coil to blow air in the direction of the interior of the interior, it is possible to obtain the optimum air volume for the air volume and capacity that changes each time such as load fluctuations on the interior side. Even if air conditioning with a constant capacity such as a perimeter requires only adjustment of air volume due to changes in temperature, etc., air conditioning with different air volumes and capacities can be expected on both sides at the same time. It has the following effects.
