Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air conditioning system for large spaces such as various industrial plant buildings, halls, theaters, etc., and particularly to uniform temperature distribution and air volume distribution in large spaces. and a device that can be expected to improve air pollution removal efficiency.

[Prior Art] A conventionally used air conditioner will be described with reference to FIGS. 5(a) and 5(b).

FIG. 5(a) is a horizontal sectional view of a conventional air conditioner installed in a large space, and FIG. 5(b) is a vertical sectional view of the same. In FIGS. 5(a) and (b), 1 is a large space, 2
is the air supply port, 3 is the exhaust port, 4 is the air supply duct, 5 is the
Exhaust duct, 6, supply air blower, 7, exhaust blower, 8
9 is a heating/cooling device, 9 is a filter, and 10 is a structure.

The functions of the conventional device are a heating/cooling device 8 (which can be used by switching between heating and cooling functions at any time), and the heated or cooled outside air is supplied into the room by an air supply blower 6, and then passed through an air supply duct. 4 from a plurality of air inlets 2 and from a plurality of exhaust ports 3 of an exhaust duct 5 installed on the opposite wall in a substantially straight line as shown by the arrow.

The air passes through the filter 9, is supplied to the exhaust blower 7, and is exhausted. That is, in conventional air conditioners for large spaces, the supply air duct 4 and the exhaust duct 5 are often installed on opposing walls, and the air flow is limited to the air supply port 2.
Since the shortest bus from the air outlet to the exhaust port 3 is taken, the flow of air in the large space is linear, making it difficult to make the temperature distribution uniform. In order to equalize the temperature distribution within a large space, it is necessary to increase the number of air supply ducts and exhaust ducts, which increases equipment costs. In addition, since the air flow takes the shortest route, dirt and debris accumulate in the upper part of the large space, making it impossible to completely achieve the intended purpose.

In addition, as a related known example, Japanese Patent Application Laid-Open No. 57-18895
Publication No. 6, JP-A-57-196029, JP-A-5
8-164939, etc.5, all of which relate to the control of air conditioners divided into multiple rooms;
It has nothing to do with equalizing the flow of air within a room like the present invention.

[Problems to be Solved by the Invention] With the above-mentioned conventional technology, it is not possible to equalize the temperature distribution in a large space, and therefore comfort cannot be obtained from a human experience. There was also a problem in terms of health care because the gas remained inside the body and was not completely exhausted.

An object of the present invention is to provide an air conditioner that can equalize the temperature distribution in the large space cabinet and improve the efficiency of removing dust, lumps, etc.

[Means for Solving the Problems] The configuration of the air conditioner of the present invention for solving the above problems includes a heating/cooling device, a supply air blower, and a plurality of them on one wall side in a building space. Provide an air supply duct with an air supply port,
An exhaust duct with multiple exhaust ports on the other wall side,
In an air conditioner including a filter and an exhaust blower, a first air supply opening and a second exhaust opening in place of the plurality of air supply openings, a filter and a valve are provided on one wall side. A supply air return air passage connected to the supply air blower is provided, and on the other wall side, a first exhaust opening and a second air supply opening in place of the plurality of exhaust ports, a filter, and the exhaust air are provided. An exhaust return air passage is provided in which a blower, a valve, and a check valve are connected.

[A first air supply opening (2,) and a second exhaust opening (3□) are located at the same height on one side of the opposite wall in the large space.
2. A direction device pointing upwards shall be provided. In addition, a supply air return air passage will be provided outside the large space, and a filter, valve, and supply air blower will be connected to it. A second air supply opening (2,) and a first exhaust opening (31) are provided on opposing wall sides, and an upward direction device is provided in 2□. Similarly, outside the large space,
Provide an exhaust return air path consisting of a filter, exhaust blower, valve, and check valve.

Now, if the supply air blower and exhaust blower are operated (with the multi-valve open), the air blown from 21 will circulate upward (toward the ceiling) in a roughly semicircular shape, and will be supplied from 32. The air is blown back into the air. Similarly, the air blown from 2□ circulates upward in an almost semicircular shape, and then 3□
The air is then guided to the exhaust return airway, where the circulation is repeated. At this time, near the center of the large space, both air flows mix, and a portion of the mixture (air volume depends on the capacity of the equipment) is exhausted to the outside and replaced with fresh air.

By arranging the above-mentioned equipment, compared to the conventional example, (1) the air flow path becomes longer; (2) The flow path becomes three-dimensional, allowing air to be replaced in every corner of the space.

(3) Since air is mixed and stirred near the center, the replacement efficiency is improved.

[Example] An example of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows one embodiment of the present invention, and FIG. 1(a) shows
The horizontal cross-sectional view, FIG. 13(b) is a vertical cross-sectional view taken along line AA' in FIG. 4(a), and FIG. The numbers in FIG. 1 are the same as in FIG.
is a valve, 12 is a check valve, 13 is a flow bath, 14 is a
Supply air return air passage, 15 is an exhaust return air passage, 2□ is a first air supply opening, 22 is a second air supply opening, 3□ is a first exhaust opening, 3 is a first air supply opening; 2 exhaust openings. Figure 1(a)
In the horizontal cross-sectional view of
A supply air return line 14 consisting of a valve 11 and a filter 9 is provided in the air supply duct 4 between the two, and the tip of this supply air return line 14 is connected to an exhaust port 32 provided on the same plane as the air supply port 21. That is, the air in the large space 1 is exhausted to the exhaust port 32 and guided to the inlet of the air supply blower 6 via the filter 9 and the valve 11.

On the other hand, the exhaust port 3□ on the other wall of the large space 1.

Exhaust filter9. And, for the exhaust line of the exhaust blower 7, a line 15 for returning exhaust gas from the exhaust blower 7 to the large space 1 is provided, and a valve 11. Check valve 1
2, and the air from the exhaust blower 7 is supplied into the large space 1 from the air supply port 22 (one part is directly exhausted to the outside). By providing the supply air return line 14 and the exhaust air return line 15, the flow path 1 in the large space 1 is improved.
3 becomes as follows. It is assumed that the air supply angles of the air supply ports 2□, 22 provided on opposing walls across a large space are set in advance so that air is blown out obliquely upward. The air supplied into the large space 1 from these air supply ports 2□, 2□ forms a flow path as shown by the arrow in FIG. Exhaust each.

If we look at this in a vertical section, the flow bus 13 can be seen in Figure 1 (
AA' vertical section in b) and B-I3 in Figure 1(c)
'It will look like the one shown in the vertical section. Path 1 of this flow
3 is.

When developed three-dimensionally and shown in a perspective view, it becomes as shown in Fig. 2. In this way, the flow bus 13 becomes like two ellipsoidal orbits and is considerably longer than the conventional one.

Figures 3(a) and 3(b) are vertical cross-sectional views of the air supply port, and Figures 3(C) and (
d) is a plan cross-sectional view of the air supply port. In FIGS. 3(a) and (b), 4 is an air supply duct, 16 is an air supply expander, 17 is an air supply direction device, 18 is a bearing, 19 is a gear reducer, 20 is a motor, and 21 is a flow path. , 22 indicates a gear. The air supply direction device 17 has, for example, a conical structure and can be easily manufactured by deforming an iron plate. This air supply direction device is air supply expander 1
6, as shown in FIG.
1 is formed. The air supply expander 6 has a conical duct structure, and the air supply expander 16 is connected to the air supply duct 4 via a bearing 18. In addition, 20 air supply expanders 1
A gear 22 is provided on the outer periphery of the gear 6, and the gear 22 and the gear reducer 19 rotate in conjunction with each other. This air supply expander 1
6 is easy to manufacture and consists of general-purpose materials.

The gear reducer 19 is also a general-purpose one, and is driven by a general-purpose motor 20.

Assuming the initial state as shown in FIGS. 3(a) and 3(C), air from the air supply duct 4 is supplied into the large space 1 through the flow path 21 formed at the upper part of the air supply expander 16. . Next, by driving the motor 20 and rotating the gear reducer 19, the air supply expander 16 is rotated. The air supply direction device also rotates at the same time, and a flow path 21 is formed directly below as shown in FIGS. 3(b) and 3(d). Thereafter, by continuously changing the position of the flow path 21 between the supply air expander upper 6 and the supply air direction device 17 by driving the motor 20, the air from the supply air duct 4 is directed into the large space 1. will be supplied with air. The air supply ports shown here are 2□ in Figures 1 and 2,
It is 2□. The size of the flow path 21 can be arbitrarily set by setting the sizes of the air supply expander 16 and the air supply direction device 17 in advance.

The air supply port in FIG. 3 is replaced with the air supply port 21.2 in FIG. By using this method, it is possible to continuously and freely change the air supply angle of a large space potter.

FIG. 4 is a motor drive control block diagram of this embodiment. In FIG. 4, 23 is a temperature detector, 24 is a temperature difference comparison circuit, 25 is a temperature setting device, 26 is a gear reduction weak rotation position detector, 27 is a motor control circuit, and 28 is a motor drive It is a circuit.

In FIG. 4, a plurality of desired temperature detectors 23 are set in advance in the large space 1. The temperature setting device 25 is
For example, the temperature sensor 23 is a potentiometer.
For example, if the output value of the temperature detector 23 is larger than the output value of the temperature setting device 25, the temperature difference comparison circuit 24
The output of
stop. In other words, the flow paths 21 of the air supply expander 16 and the air supply direction device 17 are aligned in a direction in which the temperature value in the large space 1 is higher than the temperature set value, and air is supplied intensively. The circuit that detects a certain direction and stops the motor when the temperature instruction value in that direction is high is a general-purpose circuit, and the control circuit shown in FIG. 4 can be easily realized by a combination of analog circuits or semiconductor logic elements.

[Effects of the Invention] Since the present invention is configured as described above, it produces the effects described below.

Air supply and exhaust ports with variable direction are installed on one wall of the large space, and an air supply port with variable direction is provided on the other wall.

Since an exhaust port is provided, the air supplied into the large space through the rain air supply port lengthens the flow path and is exhausted from both exhaust ports. This increases the mixing and stirring effect of the air.

The direction of both air inlets can be changed periodically, further increasing the effect of air stirring in the large space. Additionally, if there is a high-temperature area in the large space, the air supply port stops rotating, and by supplying air in a concentrated manner, the temperature distribution can be made more uniform. Furthermore, the removal efficiency of dust, clumps, etc. can be improved.
