Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air conditioning ventilation system, and in particular, a tornado is artificially generated through an air conditioner to mix fresh outside air and contaminated inside air. This invention relates to an improvement in an artificial tornado type air conditioning ventilation mechanism that can simultaneously and automatically ventilate the air.

[Conventional technology]

Conventional air conditioning ventilation systems often use a method in which conditioned air is blown out from the ceiling through a duct and sucked in from a suction louver toward the floor to ventilate the room. In these methods, the conditioned clean air is mixed with the contaminated air in the room and sucked out from the suction louver, so the contaminated air in the room is diluted and ventilated, resulting in poor ventilation efficiency. Particularly in rooms that require a highly clean space, such as a clean room, an air conditioning ventilation system is used that blows out clean air from the entire ceiling in a laminar flow, sucks it into the entire floor using a suction louver, and then discharges it to the outside. It has been adopted. For this reason, it is necessary to provide blow-off holes on the entire ceiling surface or to provide a suction louver that can suck the entire floor surface, which not only results in high costs but also causes many inconveniences in terms of work.

Therefore, the present applicant developed a method for efficient air conditioning and ventilation by artificially generating tornadoes, and filed a patent application (Japanese Patent Application No. 61-310153 (Japanese Unexamined Patent Publication No. 63-169434)).
and Japanese Patent Application No. 1983-171172 (Japanese Patent Application No. 64-19240)
No.)) was completed. These inventions were developed to solve the conventional problems as described above. In the invention, an air blowing pipe with an air blowing hole is provided, several of the air blowing pipes are arranged, and the air blowing pipes are connected to an air conditioner via an air blowing pipe and an air suction pipe, and the air blowing pipe of the air conditioner is Air is released from the air outlet of each air outlet pipe through the blower pipe to form an air curtain between each air outlet pipe, and air is sucked from the air suction pipe to form a free space in each air outlet pipe. This is an artificial tornado type air conditioning and ventilation mechanism that generates an artificial tornado, exhausts contaminated air inside the room to the outside of the room via the artificial tornado, and blows clean air into the room. The invention is based on the artificial tornado type air-conditioning ventilation mechanism according to the invention, in which artificial tornadoes are generated at two desired locations on the left and right side facing each other.
The purpose is to use a continuous tornado type air conditioning and ventilation system. However, although these inventions and inventions can mechanically solve the problems of the conventional methods, they cause inconvenience for workers when there are obstacles in the room, and there are many problems in practical use. A problem had arisen.
In addition, as in the invention of 2, it is possible to solve the problems caused by obstacles caused by creating an artificial tornado in the center of the room, but it is possible to solve the problems caused by obstacles caused by creating an artificial tornado in the center of the room. The structure is not such that the cleanest air always flows directly over the workbench, and the cleanest clean air and contaminated air swirl and mix. It is difficult to expose only to clean air.

[Problem that the invention seeks to solve]

The problem to be solved by the present invention lies in improving these problems. In other words, when an artificial tornado is generated by the artificial tornado generation mechanism developed by the applicant, the cleanest air is blown downward from the ceiling so that the work table, etc. is always exposed to the cleanest clean air. The problem that the present invention attempts to solve lies in trying to generate an artificial tornado by exposing the tornado to hot or cold air.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a schematic configuration diagram of an air conditioner to which the artificial tornado type air conditioning ventilation mechanism of the present invention is applied, and Fig. 2 is a
FIG. 2 is a perspective view showing the configuration of an artificial tornado type air conditioning ventilation mechanism. In both figures, A indicates an air conditioner, and the air conditioner A includes an air conditioner 1, an artificial tornado type air conditioning ventilation mechanism B of the present invention installed in a room 2, and piping connecting these. Consists of. The air conditioner 1 has at least a built-in blower and converts the incoming air into air under predetermined conditions, such as clean warm air,
The outlet 1a of this air conditioner 1
is connected by a pipe 3 to an inlet 4a of a ceiling-side air blowing pipe 4 of the artificial tornado type air conditioning ventilation mechanism B. This artificial tornado type air conditioning ventilation mechanism B is constructed as follows. That is, a filter (purifier) 5 is built into the ceiling air blowing pipe 4 to further purify the air that has been made under predetermined conditions by the air conditioner 1. A predetermined number of air blowing holes 4b are provided. The ceiling-side air blowing pipe 4 having such a configuration is provided on the ceiling surface 6 of the room 2 so that the air blowing hole 4b faces downward into the room 2, and is also installed on a workbench installed in the room 2. It is located directly above 7. Inside the room 2, floor-side air blowing pipes 8 and 9 are provided at the left and right corners in FIG. 1, respectively. These floor side air blowing pipes 8, 9 have air blowers 10, 1.
0 is built-in. The floor-side air blowing pipes 8 and 9 are provided with suction holes 8a and 9b for sucking in the air in the room 2 and air blowing holes 8b and 9b for blowing out the air, respectively. Furthermore, air suction pipes 11, 12, 13, and 14 are provided on the side walls of the room 2, facing each other. As described above, the artificial tornado type air conditioning ventilation mechanism B is configured.

Air suction pipes 11, 12, 13, and 14 of the artificial tornado type air conditioning ventilation mechanism B are connected to the inlet 1b of the air conditioner 1 through a collection pipe 15.

Next, the operation of the air conditioner A having the above configuration will be described.

First, the air flowing into the air conditioner 1 is made into air under predetermined conditions and given a constant pressure by a blower, passes through piping 3, enters ceiling air blowing pipe 4, is further cleaned by filter 5, Clean air is blown out from the air blowing hole 4b of the ceiling-side air blowing pipe 4 in the direction of the arrow C in FIGS. 1 and 2, that is, in the downward direction, and is supplied onto the workbench 7. Contaminated air generated by working on the workbench 7 is constantly replaced by clean air. This replaced contaminated air is sucked into the suction holes 8a, 9a of the floor-side air blow-off pipes 8, 9 by the blowers 10, 10 in the floor-side air blow-off pipes 8, 9 provided in the corners of the room 2. , pressure is applied to the air discharge hole 8
It is blown out from b, 9b. This blown air forms an air curtain D. and,
Each air suction pipe (suction port) 11, 12, 1
Air in room 2 is connected to collective pipe 1 by 3 and 14.
When the air is sucked by the air conditioner 1 through the air filter 5, a negative pressure core section is created between the opposing air suction pipes 11 and 13 and between the air suction pipes 12 and 14.
E ₁ and E ₂ are formed, respectively. This negative pressure core part
Due to the formation of E ₁ and E ₂ , an artificial tornado parallel to the ceiling surface 66 and clockwise in FIGS. 1 and 2
H ₁ and counterclockwise artificial tornado H ₂ are formed, respectively.

The principle of generation of this artificial tornado H will be explained in more detail with reference to FIG.

FIG. 3 illustrates the artificial tornado generation mechanism and its principle in the artificial tornado type air conditioning ventilation mechanism shown in FIGS. 1 and 2.

When air is blown out from the air blowing holes 8b or 9b, an air curtain D is formed, and at the same time it rotates along the inner wall surface, so this air curtain D
Due to the wake effect of E is formed. That is, when a circulating flow G is formed within the air curtain D, centrifugal force is applied to the air particles by this circulating flow G. On the other hand, a negative pressure is generated in the center of the circulating flow G due to suction. Due to the centrifugal force, the pressure region does not reach the periphery, but forms a negative pressure core E along the center of the circulating flow G, and extends for an average length. This negative pressure core part E applies a centripetal force to the circulating air particles, and within the range where centrifugal force and centripetal force are balanced, the circulating flow G becomes a vortex flow (spiral flow) and flows toward the air suction pipe 11 while converging at the center. An artificial tornado H will be generated towards the area.

The fluid characteristics of this artificial tornado H are: a) it has directional suction (the flow velocity towards the air suction pipe does not change even if it leaves the air suction pipe); b) it flows toward the center in a tornado shape c. A negative pressure core is formed in the center of the circulating flow and extends evenly toward the air suction pipe; d. Centrifugal force and suction force are balanced. , tornadoes can be formed freely from low speed to high speed. In this way, contaminated air generated by working on the workbench 7 is immediately replaced by clean air that has passed through the filter 5, and the workbench 7 is always exposed to clean air. The replaced contaminated air is sucked in by the air blowing pipes 8, 9, and is increased in pressure and blown out by the blowers 10, ₁₀ to form artificial tornadoes _H1 , H2, and air suction pipes 11, 12, It passes through 13 and 14 and is discharged from the room 2. Therefore, there is no need to provide clean air blow-off holes and contaminated air suction louvers over the entire ceiling surface 6 and floor surface of the room 2.
This has the effect that clean air can always be supplied directly onto the workbench 7. In addition, since the air suction pipe 11 can be freely set in a position that does not interfere with the work, for example, if it is installed above and in the corner of the room 2 as shown in Figs. 1 and 2, the artificial tornado H ₁ and _H2 can be generated without being affected by work, etc., and have the effect of being able to ventilate contaminated air. Furthermore, the ventilation system using the artificial tornado H has a simple structure and has the advantage of being able to reduce costs.

FIG. 4 shows another embodiment of the artificial tornado type air-conditioning and ventilation system B of the present invention, which generates one artificial tornado H and is used in small-scale clean rooms and the like. Since its structure, operation, and effect are similar to those of the embodiment shown in FIGS. 1 to 3, symbols will be attached and explanation thereof will be omitted.

In the description of this embodiment, the artificial tornado type air conditioning ventilation mechanism B of the present invention is installed in the room 2, but even if the room 2 is not present, the air curtain D can be used. It is possible to obtain the same effect because it is blocked by
Further, in this embodiment, clean air is supplied into the room 2, but it is also possible to supply hot air or cold air to the room 2 for local heating and cooling.

〔Effect of the invention〕

Since the present invention is configured as described above, it has the following effects.

A. Artificial tornadoes can be easily generated using conventional air conditioning equipment, so clean air can be directly supplied to areas where clean air is constantly needed, such as over workbenches, and contaminated air generated by workbenches can be removed. The contaminated air is quickly replaced, and the replaced contaminated air can be suctioned by the artificial tornado and quickly discharged outside the room.

(b) Furthermore, since the generation of an artificial tornado and the collected contaminated air can be activated simultaneously, air-conditioning ventilation can be achieved that is more efficient than conventional general ventilation methods.

C. By taking advantage of the characteristics of artificial tornadoes, such as increased suction directionality and collection efficiency, high-performance air conditioning and ventilation can be achieved with less wind power.

D. Because there is no need for air outlets or suction louvers on the ceiling or floor, equipment construction and costs are not required compared to clean rooms with laminar ventilation.

E) A stable tornado can be generated without the negative pressure core of the artificial tornado being destroyed by mechanical equipment or human work.
