Description

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

[Conventional technology]

The conventional air blower mechanism in a room is as shown in Figures 3 and 4.
FIG. 3 shows a general air conditioning ventilation mechanism, and FIG. 4 shows a clean room equilaminar flow ventilation mechanism. As shown in Figure 3, the air conditioning ventilation mechanism that has been commonly used in the past sucks in outside air OA introduced from outside the room through an air conditioner M, and also sucks in some air from inside the room to perform air conditioning. The clean room air supply SA is blown out from the blowout anemo 12 through the duct 11 installed in the upper part.
On the other hand, it is sucked in from a suction louver installed on one side wall in the vertical direction, and a portion of this sucked room exhaust air RA is sucked into the air conditioner M again, but most of it is exhausted to the outside as exhaust air EA. It turns out.
In this method, conditioned clean air is supplied into the room, but because the air conditioning cycle is such that it is mixed with dirty air in the room and sucked in, it is not only diluted ventilation but also extremely ventilation. It has the disadvantage of being inefficient. In addition, in the case of an air conditioning ventilation mechanism such as laminar flow ventilation that requires a highly clean space such as a clean room, clean room air SA from the air conditioner M is supplied from the entire ceiling surface as shown in Figure 4. laminar flow,
Furthermore, the air is blown into the room through a filter 14, and the entire floor is sucked in from the suction louver 13, and all of this sucked room exhaust air RA is discharged outside as exhaust air EA, so that it does not mix with the room air again. It's getting old. This method not only requires high construction costs, but also causes many inconveniences, such as installing an air outlet over the entire ceiling surface or installing a louver that can suck the entire floor surface.

Therefore, the applicant of the present application has developed a method of generating an artificial tornado and discharging harmful gases and dust. For example, a method for using an artificial tornado with suction directionality in free space was developed and disclosed in Japanese Patent Application No. 61-106384 (Japanese Unexamined Patent Publication No. 62-261842). That is, the present invention provides a mechanism that can easily generate an artificial tornado, which has been thought impossible in the past, and a method of utilizing the artificial tornado generated by the mechanism. The gist of this invention mechanism is that several air blowing pipes are arranged between shielding plates provided with suction ports, and a circulating flow (swirling airflow )
This is a mechanism that generates an artificial tornado by forming a circular flow (swirling airflow) and sucking air from the center of this circulation method (swirling airflow). ), a centrifugal force is applied to the center part, and a negative pressure is generated in the center part, and a negative pressure core part elongated in the suction direction is formed, and a centripetal force is applied to this negative pressure core part. The circulating flow (swirling airflow) in the range where the and centrifugal force are balanced becomes a (spiral flow) and is converged at the center of the circulating flow (swirling airflow) to artificially generate a tornado in the suction direction. It is something. The fluid characteristics of the artificial tornado generated by this invention are: (a) it has directivity in the suction (the flow velocity toward the suction port does not change even if it moves away from the suction port), and (b) it converges to the center in a tornado shape. (c) A negative pressure core is formed at the center of the circulating flow and extends evenly toward the suction port; (d) Centrifugal force and centripetal force are balanced, allowing the flow to flow from low to high speeds. This is due to the fact that tornadoes can be formed at will. Furthermore, the effect of this invention is to generate an artificial tornado in the upward, lateral and inclined directions with suction directionality in free space, and to generate an artificial tornado in the upward, lateral and inclined directions with suction directionality inside the pipe. By generating an artificial tornado and by generating an artificial water tornado with suction directionality underwater, the fluid characteristics of each type can be applied to make it usable for a wide range of applications.

[Problem that the invention seeks to solve]

However, the above-mentioned invention by the present applicant merely clarifies the generation mechanism of an artificial tornado and its conceptual usage, but does not specify the specific usage. Therefore, the above-mentioned artificial tornado generating mechanism solves the problem of the conventional air conditioning ventilation mechanism shown in Figs. 3 and 4, which is poor ventilation efficiency and dilution ventilation, and has air outlets all over the ceiling of the room. However, it could not be used to solve the problems such as the need for a louver that can suck the entire floor surface.

Therefore, the present invention has been made in view of the above-mentioned circumstances, and it is possible to achieve good ventilation efficiency and sufficient ventilation in the room, and to provide air outlets and suction louvers on the entire surface of the ceiling, floor, etc. The purpose is to provide an air conditioning ventilation mechanism that does not require an artificial tornado.

[Means for solving problems]

The present invention was developed in order to solve the above-mentioned problems, and includes providing a plurality of air blowing pipes with air blowing holes along the wall surface of a room, and connecting the air blowing pipes to the air blowing holes. A ceiling surface arranged so that the directions are in the same rotational direction along the wall surface, and located approximately at the axial center of the swirling airflow formed in the room by the wake action of the air blown out from the air outlet. and a suction port is provided on at least one side of the floor surface, and an air conditioner is connected to the suction port and the air blowing pipe, respectively,
Generate an artificial tornado in the room by blowing out air from the air outlet and sucking air from the suction port, and discharge contaminated air existing in the room by the vortex convergence of the artificial tornado;
All of these problems can be solved by supplying conditioned air into the room from the air outlet. That is, the means for solving the problems of the present invention is to generate an artificial tornado in a free space in a room using the air blowing and suction effects of an air conditioner, and to create an artificial tornado in a free space in a room by using the generated artificial tornado. The purpose is to purify and ventilate the contaminated air inside.

[Effect]

The present invention applies the principle of generating an artificial tornado. First, the artificial tornado mechanism has a suction port on either the ceiling or floor of a room, several air blowing pipes are arranged along the wall of the room, and the space between these air blowing pipes is This mechanism generates an artificial tornado by forming a circulating flow (swirling airflow) within an air curtain that is continuously formed, and sucking air from the center of this circulating flow (swirling airflow). In other words, the principle of the artificial tornado mechanism is to create a circulating flow (swirling air current) through air circulation (air curtain).
At the same time, a centrifugal force is applied to the center, and a negative pressure is generated in the center by suction, forming an elongated negative pressure core in the suction direction. The circulating flow (swirling air current) within the range where the force is balanced becomes a vortex flow (spiral flow), which is converged at the center of the circulating flow (swirling air current) and artificially generates a tornado in the suction direction. It is.

Next, through the artificial tornado thus generated, air supply and ventilation within the room can be performed simultaneously and automatically.

In addition, this negative pressure core part B applies centripetal force to the circulating air molecules, and within the range where centrifugal force and centripetal force are balanced, the circulating flow becomes a vortex flow (spiral flow) while converging at the center and directed toward the air suction part. An artificial tornado will be created.

〔Effect of the invention〕

In addition, since the generation of an artificial tornado and the collected contaminated air can be generated simultaneously, air-conditioning ventilation can be obtained that is more efficient than conventional laminar ventilation.

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. There is no need for any blowout or suction louvers on the ceiling or floor, so there is no need for equipment construction or costs.
