(First embodiment)
1. Outline of Air Conditioning System In this embodiment, the present invention is applied to the structure of a machine room MR for a data center shown in FIG. The data center is provided with a server room SR in which a plurality of information communication technology devices (hereinafter referred to as ICT devices) are installed.

  At least one air conditioner 1 is installed in the machine room MR. The air conditioner 1 maintains the temperature, humidity, and the like of air in the server room SR (hereinafter referred to as “inside air RA”) within a predetermined range by supplying conditioned air such as cold air to the server room SR.

  That is, a plurality of ICT devices (not shown) are installed in the server room SR. A plurality of ICT devices generate heat during operation. The air conditioning system executes the full return air operation mode when the outside air temperature is higher than the room temperature of the server room SR. In the full return air operation mode, the inside air RA is cooled by the air conditioner 1, and the cooled air is supplied to the server room SR as the supply air SA.

  When the outside air temperature is lower than the room temperature of the server room SR, the air conditioning system executes the mixed air operation mode. In the mixed air operation mode, air introduced from outside the building (hereinafter referred to as outside air OA) and the inside air RA are mixed to adjust the temperature of the supply air SA. Thereby, the cooling load of the air conditioner 1, that is, power consumption is reduced.

  The casing of the air conditioner 1 contains at least a cooling heat exchanger (not shown), a blower (not shown), and the like. A blower outlet 1A is provided on the surface on the server room SR side of the substantially hexahedron-shaped housing.

  An intake port 1B is provided on a surface of the housing different from the air outlet 1A. The blower outlet 1A is an opening through which the supply air SA blows out. The intake port 1B is an opening through which air to be supplied to the server room SR is sucked.

2. Structure of machine room (air conditioner room) (see Fig. 1)
2.1 Mixed Air Chamber The machine room MR according to the present embodiment also functions as an “air mixed chamber for mixing the inside air RA and the outside air OA”. That is, in the mixed air operation mode, the inside air RA and the outside air OA are introduced into the machine room MR.

  Since the air conditioner 1 sucks air in the machine room MR, an air flow is generated in the machine room MR. For this reason, the inside air RA and the outside air OA introduced into the machine room MR are mixed in the course of the path sucked into the air conditioner 1.

2.2 Mixing Promotion Structure In the machine room MR, an mixing promotion member 10 that promotes mixing of the inside air RA and the outside air OA is provided. The air-fuel mixture promoting member 10 includes at least a first partition member 11 and a second partition member 12.

  The first partition member 11 is a plate-like member provided on the upper side from the air inlet 1 </ b> B of the air conditioner 1. The first partition member 11 functions as a baffle plate that prevents the inside air RA and the outside air OA introduced into the machine room MR from flowing in the vertical direction by expanding in a substantially horizontal direction above the intake port 1B. To do.

  The inside air introduction unit 13 has at least an inside air port 13A. The inside air port 13A is an introduction port that communicates with the server room SR, and is an introduction port that opens above the first partition member 11 and introduces the inside air RA into the machine room MR.

  The inside air introduction portion 13 according to the present embodiment is provided with a damper (not shown) and a filter 13B. The damper is a variable throttle for adjusting the air volume of the inside air RA introduced into the machine room MR. The filter 13B captures and removes dust and the like in the introduced inside air RA.

  The outside air introduction unit 14 has at least an outside air port 14A. The outside air port 14A is an “outside air OA introduction port” that communicates with the outside of the building and faces the inside air port 13A across a space 15A (hereinafter referred to as a collision space 15A).

  “The inside air port 13A and the outside air port 14A face each other across the collision space 15A” means that “the arrangement relationship between the inside air port 13A and the outside air port 14A is blown out from the inside air port RA and the outside air port 14A. It means that it is in the “positional relationship in which the outside air OA can collide with the collision space 15A”.

  Therefore, for example, even if the center axis of the inside air port 13A and the center axis of the outside air port 14A are displaced in the horizontal direction and the vertical direction, the inside air RA blown out from the inside air port 13A and the outside air OA blown out from the outside air port 14A. Is an arrangement relationship that can collide in the collision space 15A, "the inside air port 13A and the outside air port 14A face each other across the collision space 15A".

  The “center axis of the inside air mouth 13A” is the mainstream direction of the inside air RA blown out from the inside air mouth 13A. Specifically, the central axis line coincides with a virtual line that passes through the centroid of the graphic drawn by the outer edge of the inside mouth 13A and is orthogonal to the graphic.

  The “center axis of the outside air port 14A” is the mainstream direction of the outside air OA blown out from the outside air port 14A. Specifically, the central axis line is a virtual line that passes through the centroid of the graphic drawn by the outer edge of the outside air opening 14A and is orthogonal to the graphic.

  The outside air introduction section 14 is provided with a damper (not shown) and a filter 14B. The damper is a variable throttle for adjusting the air volume of the outside air OA introduced into the machine room MR. The filter 14B captures and removes dust and the like in the introduced outside air OA.

  The outside air port 14A is located at a position shifted to the inside air port 13A side with respect to the outside air side end portion 11A or just above the outside air side end portion 11A. The outside air side end portion 11 </ b> A is an end portion on the outside air port 14 </ b> A side of the first partition member 11.

  It should be noted that the outside air port 14A according to the present embodiment is at a position shifted to the inside air port 13A side with respect to the outside air side end portion 11A. The outside air duct 14C is a duct that guides outside air OA to the outside air port 14A. And the inlet 1B of the air conditioner 1 which concerns on this embodiment becomes a structure opened to the outdoor air side edge part 11A side.

  The second partition member 12 is a plate-like member extending from the outside air side end portion 11 </ b> A side of the first partition member 11 toward the lower side. The second partition member 12 serves as a baffle plate that prevents the inside air RA and the outside air OA introduced into the machine room MR from flowing linearly into the intake port 1B by expanding in the vertical direction from the outside air side end portion 11A side. Function.

  The air-fuel mixture promoting member 10 according to the present embodiment includes a pair of third partition members 16A and 16B as shown in FIG. The pair of third partition members 16 </ b> A and 16 </ b> B have plate surfaces that are substantially orthogonal to the plate surface of the first partition member 11 and the plate surface of the second partition member 12.

  That is, the air-fuel mixture promoting member 10 constitutes a covering member that is open only on the intake port 1B side and the lower side. For this reason, the air existing around the air-fuel mixture promoting member 10 is restricted from flowing into the intake port 1 </ b> B from above the lower end of the second partition member 12.

In other words, the air present around the air-fuel mixture promoting member 10 flows into the air-fuel mixture promoting member 10 from the lower side of the air-fuel mixture promoting member 10 and is then sucked into the air conditioner 1.
The air-fuel mixture promoting member 10 according to the present embodiment is supported by the casing of the air conditioner 1. Specifically, the air-fuel mixture promoting member 10 is detachably attached to the casing of the air conditioner 1 by a mechanical fastener such as a bolt.

3. Features of Machine Room (Air Conditioner Room) Structure The inside air port 13A and the outside air port 14A face each other across the collision space 15A. Thereby, since the inside air RA and the outside air OA collide in the collision space 15A existing between the inside air port 13A and the outside air port 14A, mixing of the inside air RA and the outside air OA can be promoted.

  The outside air port 14A is located at a position shifted toward the inside air port 13A with respect to the outside air side end portion 11A. Thereby, the inside air RA and the outside air OA collided and mixed in the collision space 15A meander so that the flow direction is bent at the outside air end portion 11A as shown in FIG. Therefore, the flow path length from the location where the inside air and the outside air collide to the air inlet 1B of the air conditioner 1 can be increased.

  That is, the air collided and mixed in the collision space 15A (hereinafter, referred to as air-fuel mixture) flows to the outside air side end portion 11A side, and the downward flow direction is turned at the outside air side end portion 11A. The air-fuel mixture is mixed in the space 15B (hereinafter referred to as the air-mixing chamber 15B) surrounded by the second partition member 12 and the inner wall of the machine room MR, and the air-fuel mixture 15B is mixed in the second air-fuel mixture chamber 15B. It circulates toward the lower end side of the partition member 12.

  Thereafter, the air-fuel mixture flows into the air-fuel mixture promoting member 10 from the lower end of the second partition member 12 and is sucked into the air conditioner 1 from the air inlet 1B and then blown from the air conditioner 1 toward the server room SR. The Therefore, mixing of the inside air RA and the outside air OA is promoted in a path from the collision space 15A to the intake port 1B via the air mixture chamber 15B.

  A second partition member 12 extending from the first partition member 11 toward the lower side is provided on the outside air side end portion 11 </ b> A side of the first partition member 11. As a result, it is possible to further increase the flow path length of the inside air RA and the outside air OA from the collision space 15A to the air inlet 1B of the air conditioner 1 through the mixed air chamber 15B. Therefore, it becomes possible to further promote the mixing of the inside air RA and the outside air OA.

  The air-fuel mixture promoting member 10 is supported by the casing of the air conditioner 1. Thereby, compared with the structure where the air-fuel mixture promoting member 10 is installed in a building, the air-fuel mixture promoting member 10 can be easily installed.

  That is, if the air-fuel mixture promoting member 10 has a structure installed in a building, it is affected by the building structure during construction. On the other hand, in this embodiment, since the air-fuel mixture promoting member 10 is supported by the air conditioner 1, the construction can be easily performed without being substantially affected by the building structure during construction.

  The air-fuel mixture promoting member 10 is detachably attached to the air conditioner 1. Thereby, since the air-fuel mixture promotion member 10 etc. can be removed at the time of the maintenance of the air conditioner 1, it can suppress that a maintainability falls significantly.

The air-fuel mixture promoting member 10 is provided with third partition members 16A and 16B that restrict air from flowing into the intake port 1B from above the lower end of the second partition member 12.
Thereby, since it becomes possible to further lengthen the flow path length from the location where the inside air RA and the outside air OA collide to the air inlet 1B of the air conditioner 1, the mixing of the inside air RA and the outside air OA is further promoted. Is possible.
