Description

  The present invention relates to an air-conditioning floor outlet device, and more specifically, air-conditioned air (compressed air, mainly cold air) from an air conditioner is circulated through an under-floor space serving as a supply path from each important point on the floor to the room. The present invention relates to a floor outlet apparatus that is used under the floor (under the floor) to be blown out.

In a large-scale room such as a data center, a server room, a computer room, etc. where a large number of various devices such as large computers, server devices, and OA devices are installed, wiring for the installed devices can be performed. The floor has a double floor structure (free access floor).
In a room having such a double floor structure, the underfloor space is used as a supply path (underfloor chamber) for supplying conditioned air (pressure air, mainly cold air) from the air conditioner. In many cases, an underfloor air-conditioning system is employed in which air-conditioned air is blown into a room through a blow-out opening provided on the floor surface facing the room.

  By the way, in a room where the amount of heat generated from the installed equipment is increasing due to the recent progress in the high concentration of the system, only the cold air is blown out from the outlet provided on the floor. In this case, the temperature rise due to the hot air generated from the installed equipment cannot be suppressed, and in some areas of the room, especially in the vicinity of the installed equipment, it is caused by stagnation of heat due to local concentration or uneven thermal load. Heat accumulation occurs. When this heat accumulation occurs, the cooling effect of the installed equipment is extremely reduced, and the installed equipment is damaged due to a temperature abnormality or the like.

  Therefore, conventionally, various air-conditioning floor outlet devices have been proposed that blow out cold air from a place where the floor surface is required (near installation equipment) and have an air volume adjustment function (for example, Patent Documents). 1 to Patent Document 3).

JP 2009-174726 A (see paragraph number 0012 and FIG. 4) Japanese Patent Laying-Open No. 2006-284130 (see paragraph number 0007 and FIGS. 1, 2, and 4) Japanese Patent Laid-Open No. 10-281541 (see paragraph numbers 0010 to 0013 and FIG. 1)

By the way, the prior art described in Patent Literature 1 and Patent Literature 2 is effective in forcing the cold air supplied from the air conditioner through the underfloor space to be blown out toward the indoor installation equipment. I can say that.
However, in this prior art, since the electric fan is used to forcibly blow out the cold air toward the installation equipment, it is easy to cause a failure due to the consumption of the electric system and the electric fan. In addition, there is a problem that a heavy burden is imposed on management such that regular maintenance is essential.
In addition, such an electric air-conditioning floor outlet device requires electric power for operating the electric fan, and thus does not meet the recent social needs for which consideration for power consumption is desired. For example, in a large-scale room where the main purpose is to reduce the amount of power (running cost) other than server equipment as much as possible, such as in a data center, installation of an electric air-conditioning floor outlet device should be avoided. Tend to be.

  In addition, such an electric air-conditioning floor outlet apparatus requires time for installation because work such as wiring is required during installation on the floor surface. And there exists a subject that installation cost starts, and also a subject that manufacturing cost becomes high because of an electric system.

On the other hand, in the prior art described in Patent Document 3, as in Patent Document 1 and Patent Document 2, installation on the floor surface can be easily performed without requiring work such as wiring, and long-term operation is possible. Although there is no risk of causing a malfunction in the use of the server, for example, a server rack in which several server devices are mounted in multiple stages, such as a server room, should be cooled toward the height of the rack. I can't spread it all over.
For this reason, air conditioning (cooling) can be achieved by mixing and stirring with hot air generated from the server equipment mounted on the lower side of the rack where cold air can reach, but on the upper side of the rack or indoor ceiling where cold air is difficult to reach There is a possibility that heat may stay without mixing and stirring with cold air.
In other words, in order to lower the internal temperature, server equipment draws in air from the front and bottom and exhausts it from the back and top. However, heat is applied to the front and the vicinity of the server equipment from the middle to the top of the rack. When the stagnation occurs, the server equipment will again suck in the air that has not been mixed and stirred with the cold air, and as a result, the cooling effect is extremely reduced as described above, causing a failure due to a temperature abnormality or the like. Become.

  Therefore, the present invention was created to solve the above-described problems, and can be easily installed and installed on the floor surface, and is directed from the entire installation equipment to each direction such as the indoor ceiling. Another object of the present invention is to provide an air-conditioning floor outlet apparatus that can blow air-conditioned air with a wide range of directivity and that can be manufactured at a low cost with a simple structure.

In order to solve the above problems, in the present invention, an air-conditioning floor outlet device that blows air-conditioned air pumped through the underfloor space into the room from the floor outlet,
The case is configured to include a case portion that communicates with the outlet and is attached to the back side of the floor surface, and one or several outlet directivity fins that are horizontally installed in the case portion. The portion is formed in a bottomed box shape having an upper surface discharge port substantially the same as the opening shape of the blowout port, and at least an air intake port for the conditioned air is provided on one side surface of the peripheral wall facing the flow direction of the conditioned air. The blowout directivity fin is formed in a substantially upward inclined shape toward the flow direction of the conditioned air and toward the upper surface discharge port, and is opposed to the air intake port. And is installed in the case portion.
The case portion is attached to the back side of an opening panel (such as a grating panel or a punching panel) serving as an outlet for the conditioned air by using a mounting bracket or a set screw, and in a double floor structure (free access floor). An attachment edge member having a metal fitting insertion hole or a screw insertion hole is provided at the opening peripheral edge of the upper surface discharge port so as to be disposed at a required place on the floor surface.

Here, it is preferable that the case portion is formed as a directional wall surface having an upward inclined shape in which the other side surface of the peripheral wall facing the air intake port is directed in the direction of the upper surface opening, and the blowing directivity The fins are arranged in several rows at appropriate intervals in the flow direction of the conditioned air in the case part, and extend from the case bottom wall to the horizontal lower end from the directional wall surface side to the air intake side. It is preferable that the height to the edge is gradually increased.
Further, the blowing directivity fin is formed so that an upward inclination angle toward the direction of the upper surface opening can be appropriately changed, and the conditioned air into the case portion is provided at the air intake port. It is preferable to further include an opening variable member that adjusts the intake flow rate.

According to such a configuration, the conditioned air circulated through the underfloor space flows into the case portion from the air intake port of the case portion that is opened facing the flow direction. The conditioned air thus blown out from the outlet into the room in the blowing direction directed by the blowing directional fins having different upward inclination angles.
Thereby, the conditioned air pumped from the air conditioner through the underfloor space is blown out in the required direction at the required place in the room. For example, a large amount of conditioned air can be blown out locally and efficiently in a required direction, such as an indoor ceiling where heat accumulation is likely to occur or the wind suction front of installed equipment.

In addition, the directional air of the case part that is inclined upward in the direction of the flow of the conditioned air is blown out in the direction required by the room in the same manner as the blowing directional fin. It can act on the opposing peripheral wall surfaces).
Moreover, the blown air volume of the conditioned air blown out in the required direction in the room can be adjusted by an opening variable member provided in the air intake.

  In addition, the installation and installation of the floor outlet device on the floor surface is performed by a simple operation using an attachment member or a set screw on the back surface of the opening panel laid at each important part of the floor surface where the outlet is provided. be able to.

According to the floor outlet apparatus for air conditioning of the present invention, the conditioned air can be blown out from the outlet into the room with local blowing directivity toward the place where heat accumulation occurs and the installation equipment where hot air is generated. it can.
As a result, heat accumulation is eliminated, and more conditioned air can be blown out in the direction required for the installed equipment, etc., so the cooling effect of the installed equipment is extremely reduced, temperature abnormalities, etc. It is possible to surely prevent the occurrence of trouble due to.
In addition, it is possible to blow air-conditioned air into the room with local blowing directivity without using electric power, so data centers that have been planned mainly to minimize the amount of electric power (running cost) It is effective for large-scale indoor air conditioning.

Moreover, when installing and installing on the back side of the floor surface facing the under-floor space, it can be installed by a simple work of attaching to the back side of the opening panel without requiring wiring or the like as in the prior art. .
Moreover, since the structure is simple, it is easy to handle and can be manufactured and provided at low cost.
