Description

  The present invention relates to an air conditioner.

  A plurality of server racks (hereinafter, sometimes referred to as racks) are installed in the data center. Each rack is a box-shaped housing and houses electronic devices such as a server device, a storage device, and a network device.

  In the data center, a rack row in which a plurality of racks are arranged in a row is arranged. Further, the plurality of rack rows in the data center are arranged such that the front faces and the rear faces of the rack rows face each other with a passage therebetween. Then, a cold aisle is formed on the front side of the rack row, and a hot aisle is formed on the back side of the rack row. By arranging the rack rows in this manner, the cool air blown under the floor by the underfloor-type air conditioner through the free access floor blows out to the cold aisle via the grating installed on the floor of the cold aisle, Cool air is supplied to the electronic device. Then, the hot air is exhausted from the electronic device to the hot aisle, and an air flow is formed from the hot aisle to allow the under-floor-type air conditioner to collect the hot air. By creating such an airflow, it is possible to efficiently cool the electronic device.

  Japanese Patent Laying-Open No. 2004-184070 (Patent Document 1) describes a technique in which a wraparound wall is provided at the front of a rack to separate a cold aisle from a hot aisle.

  Further, with the increase in power consumption of the air conditioner, a direct blow type air conditioner that blows cool air directly to a spot where cool air is difficult to reach has been used. Unlike the above-described underfloor air conditioner, the direct blow air conditioner can blow cool air at a pinpoint. The direct blowout type air conditioner includes an air conditioner main body and a blower chamber provided above the air conditioner main body. Then, the cool air blown up by the air conditioner body into the blower chamber is blown from the front of the blower chamber after being blown to the top plate of the blower chamber.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings for describing the embodiments, the same portions are denoted by the same reference numerals in principle, and the repeated description thereof will be omitted.

<Direct blow air conditioner>
First, a conventional direct-blowing air conditioner 1 will be described with reference to FIGS. FIG. 1 is a front view of a conventional direct-blowing air conditioner 1. FIG. 2 is a diagram illustrating an air flow in the direct-blowing air conditioner 1. In FIGS. 1 and 2, the direct blow air conditioner 1 is schematically illustrated for convenience of explanation.

  The direct blow air conditioner 1 sucks the air 410 from the air inlet 1100 and cools the sucked air 410 by the air conditioner main body 1000. Thereby, the cooled air 410 becomes cold air 420. After that, the air conditioner main body 1000 supplies the cool air 420 to the ventilation chamber 2000 by blowing the cool air 420 upward. The cool air 420 blown up to the blowing chamber 2000 moves upward in the blowing chamber 2000 and is blown to the top plate of the blowing chamber 2000. Thereafter, the cool air 420 blown to the top plate of the blower chamber 2000 is blown out from the cool air outlet 2300.

  As described above, the cool air 420 is moved upward and blown onto the top plate, and then blown out from the cool air outlet 2300. Therefore, as shown in FIGS. 1 and 2, there is a problem that the amount of the cool air 420 blown out from the cool air outlet 2300 is large in the upper region 1200 and is not uniform.

  Further, the cool air 420 blown up by the air conditioner main body 1000 into the blower chamber 2000 is blown to the top plate and then blown out from the cool air outlet 2300, so that the energy required to blow the cool air 420 is lost. was there.

  Hereinafter, an overall configuration of the direct-air-conditioning type air conditioner 10 according to one embodiment of the present invention will be described with reference to FIGS. 3 and 4. FIG. 3 is a front view of the direct blow air conditioner 10 according to one embodiment of the present invention. FIG. 4 is a diagram illustrating an airflow of the direct-blowing air conditioner 10 according to one embodiment of the present invention.

  As shown in FIGS. 3 and 4, a direct-blowing air conditioner 10 which is an example of an air conditioner includes an air conditioner main body 100, a blowing chamber 200 provided above the air conditioner main body 100, And a wind direction adjusting box 300 attached to the flow path outlet 230 on the front side of the chamber 200.

  The air conditioner main body 100 sucks the air 410 in the data center through the air inlet 110. Then, the air conditioner main body 100 cools the sucked air 410. The air 410 sucked into the air conditioner main body 100 becomes cool air 420 by being cooled by the air conditioner main body 100. Thereafter, the air conditioner main body 100 supplies the cool air 420 to the blower chamber 200 through the cool air supply port by blowing up the cool air 420 upward. The blower chamber 200 has a cool air outlet on the front side from which the cool air 420 supplied through the cool air supply port is discharged.

  Inside the blower chamber 200, arc-shaped plates 212 extending from the cool air supply port toward the cool air outlet are arranged at predetermined intervals, thereby forming a flow path 213 through which the cool air 420 passes.

  The cool air 420 supplied to the blower chamber 200 flows from the flow path inlet 220 to the flow path outlet 230 in the flow path formed in the guide 210. Then, the cool air 420 reaching the flow path outlet 230 is blown out along the directions of the left and right wind direction boards 310 and the vertical wind direction boards 320.

  Thereafter, the cool air 420 blown out from the flow path outlet 230 is blown out from the wind direction adjusting box 300 after passing through the left and right wind direction plates 310 and the up and down wind direction plates 320.

  In the wind direction adjustment box 300, left and right wind direction plates 310 are provided at predetermined intervals (any interval included between 15 cm and 20 cm). The wind direction adjustment box 300 is provided with vertical wind direction plates 320 at predetermined intervals (any interval included between 3 cm and 7 cm).

  The left and right wind direction plates 310 are supported so as to be swingable in a horizontal direction (left and right directions) via a swing shaft. By changing the direction of the left and right wind direction plates 310 leftward or rightward about the swing axis, the direction of the cool air 420 blown out from the flow path outlet 230 is changed leftward or rightward.

  The vertical wind direction plate 320 is swingably supported in a vertical direction (vertical direction) via a swing shaft. By changing the direction of the vertical wind direction plate 320 upward or downward about the swing axis, the direction of the cool air 420 blown out from the flow path outlet 230 is changed upward or downward.

<Guide>
FIG. 5 is a perspective view of a guide 210 provided in a blower chamber of a direct-blowing air conditioner according to one embodiment of the present invention.

  As shown in FIG. 5, the guide 210 includes a plurality of fan-shaped vertical partition plates 211 arranged vertically at predetermined intervals (any interval between 5 cm to 30 cm), and a vertical partition plate. It comprises a plurality of arc-shaped arc plates 212 arranged in a direction orthogonal to 211 and arranged concentrically at predetermined intervals (any interval between 3 cm and 20 cm). In addition, since the space | interval where the vertical partition plate 211 is arrange | positioned and the space | interval where the arc-shaped plate 212 are narrowed, the area which the cold air 420 contacts increases, and frictional resistance becomes large. Therefore, it is desirable that the interval between the vertical partition plates 211 and the interval between the arc plates 212 be as wide as possible. For example, the interval at which the vertical partitioning plates 211 are arranged is desirably any interval between 20 cm and 30 cm, and the interval at which the arc plates 212 are arranged is desirably any interval between 15 cm and 20 cm.

  The guide 210 includes a plurality of flow path inlets 220 formed by being surrounded by a vertical partition plate 211 in the left-right direction and an arc plate 212 in the up-down direction, and a plurality of flow path outlets corresponding to each flow path inlet 220. 230. Further, a flow path 213 through which cool air passes is formed in the guide 210 by being surrounded by a vertical partition plate 211 in the left-right direction and by an arc plate 212 in the up-down direction.

  The arc plate 212 has an arc shape when viewed from the side, and the cool air 420 flows smoothly along the flow channel 213 from the flow channel inlet 220 to the flow channel outlet 230. Therefore, the cool air 420 is not blown to the top plate of the blower room, and the energy loss is reduced.

  The vertical partition plate 211 and the arc plate 212 are arranged at substantially equal intervals, and each of the channel outlets 230 and each of the channel inlets 220 are arranged in a lattice. The area of each flow path inlet 220 and each flow path 213 (the area of the vertical section of the flow path 213) and the area of each flow path outlet 230 are substantially the same. By supplying the cool air 420 from each flow path inlet 220 in a state where the cool air 420 is filled in each flow path 213, the cool air 420 is pushed out from each flow path outlet 230. Therefore, the amount of the cool air 420 blown out from each flow path outlet 230 can be made uniform.

<Blow room and wind direction adjustment box>
FIG. 6A is a side view of a blower chamber 2000 of a conventional direct blow air conditioner, and FIG. 6B is a direct blow air conditioner according to an embodiment of the present invention. FIG. 3 is a view of a blower chamber 200 and a wind direction adjustment box 300 observed from the side.

  As shown in FIG. 6A, in the conventional direct-blowing type air conditioner, a left and right wind direction plate 3100 and a vertical wind direction plate 3200 are provided inside a blower chamber 2000. In the conventional direct-blowing type air conditioner, the height of the swing axis of the upper and lower wind direction plates 3200 provided at the uppermost position is lower than the height of the upper end of the blowing port 2300 of the blowing chamber 2000. Therefore, when the vertical wind direction plate 3200 is changed in a predetermined direction, a gap 3310 may be generated between the upper end of the upper and lower wind direction plate 3200 on the side of the blower chamber and the upper end of the outlet 2300.

  Further, in the conventional direct-blowing type air conditioner, the height of the swinging axis of the upper and lower wind direction plates 3200 provided at the lowermost position is lower than the height of the lower end of the blowing port 2300 of the blowing chamber 2000. Therefore, a gap 3320 may be present between the lower end of the outlet 2300 and the end of the lowermost upper / lower airflow direction plate 3200 on the blower chamber side.

  In the conventional direct blow air conditioner, there is a problem that the wind direction of the cool air 420 passing through the gaps 3310 and 3320 cannot be changed.

  As shown in FIG. 6B, in the direct-air-conditioning type air conditioner according to one embodiment of the present invention, an airflow direction adjustment box larger in the vertical direction (vertical direction) and the horizontal direction (horizontal direction) than the blower chamber 200. 300 is attached to blower room 200. Further, since the wind direction adjustment box 300 is detachably attached to the blower room 200, even when the blower room 200 cannot be separated from the air conditioner main body 100, only the wind direction adjustment box 300 can be replaced. Become. In addition, the direct-blowing air conditioner according to one embodiment of the present invention can be retrofitted at low cost.

  Inside the wind direction adjustment box 300, a left and right wind direction plate 310 and a vertical wind direction plate 320 are provided.

  Each of the vertical wind direction plates 320 can be changed in the vertical direction with the swing axis as a fulcrum. The swing axis of the upper and lower wind direction plate 320 provided at the uppermost position is attached to a position higher than the height of the upper end of the outlet of the blower chamber 200 (or at the same height). Then, the upper and lower wind direction plates 320 provided at the uppermost position swing about a position higher than the upper end of the outlet of the blower chamber 200 (or a position having the same height) as a fulcrum. Thereby, the cool air 420 passing near the upper end of the outlet comes into contact with the upper and lower wind direction plates 320. The vertical wind direction plate 320 can change the wind direction of the cool air 420 passing near the upper end of the outlet.

  In addition, the swing shaft of the upper and lower wind direction plates 320 provided at the lowermost position is attached to a position lower than the height of the lower end of the outlet of the blower chamber 200 (or at the same height). The lowermost vertical direction plate 320 provided at the lowermost position swings at a position lower than the lower end of the outlet of the blower chamber 200 (or at a position having the same height) as a fulcrum. Thereby, the cool air 420 passing near the lower end of the outlet comes into contact with the upper and lower wind direction plates 320. The vertical wind direction plate 320 can change the wind direction of the cool air 420 passing near the lower end of the outlet.

  Further, each of the left and right wind direction plates 310 can be changed in the horizontal direction with the swing axis as a fulcrum. The swing axis of the left and right wind direction plates 310 provided at the most end side (right end side) is located at one end direction (right direction) with respect to one end (right end) of the outlet of the blower chamber 200 (or at the same position). Position). The left and right wind direction plates 310 provided at the most end swing about a position (or the same position) shifted to the right from one end of the outlet of the blower chamber 200. Thereby, the left and right wind direction plates 310 can change the wind direction of the cool air 420 passing near one end (right end) of the outlet.

  Further, the swing axis of the left and right wind direction plates 310 provided on the other end side (left end side) is in the other end direction (left direction) than the other end (left end) of the outlet of the blower chamber 200. (Or the same position). The left and right wind direction plates 310 provided at the other end swing about a position (or the same position) shifted leftward from one end of the outlet of the blower chamber 200. Thereby, the left and right wind direction plates 310 can change the wind direction of the cool air 420 passing near the other end (left end) of the outlet.

  That is, the left and right wind direction plates 310 provided at both ends of the wind direction adjustment box 300 are provided outside the end of the cool air outlet of the blower chamber 200.

  Note that at least one of the left and right wind direction plates 310 and the vertical wind direction plates 320 may not be integrally swung. This makes it possible to individually change the directions of the left and right wind direction plates 310 and the vertical wind direction plates 320.

<Wind board>

  As shown in FIG. 7A, in the conventional direct blowout type air conditioner, since the length L ′ of the vertical wind direction plate 3200 is not sufficient, some cool air 420 contacts the vertical wind direction plate 3200. It is blown out from the cool air outlet to the outside. In this case, there is a problem that the vertical wind direction cannot be changed for the cool air 420 that is blown out without contacting the vertical wind direction plate 3200.

  As shown in FIG. 7B, by setting the length of the vertical wind direction plate 320 to L longer than L ′, the amount of cold air 420 contacting the vertical wind direction plate 320 increases. Similarly, increasing the length of the left and right wind direction plates increases the amount of cold air 420 that contacts the left and right wind direction plates.

  FIGS. 8A to 8C are side views of the upper and lower wind direction plates 320 of the direct blow air conditioner 10 according to one embodiment of the present invention. FIG. 8A shows an example in which the interval between the upper and lower wind direction plates 320 is 10 cm, the length of the upper and lower wind direction plates 320 is 10 cm, and the angle of the upper and lower wind direction plates 320 with respect to the horizontal plane is 10 degrees. . In the case shown in FIG. 8A, the height of the region through which the cool air passes through the vertical wind direction plate 320 is 8.3 cm.

In the case shown in FIG. 8B, the length of the vertical wind direction plate 320 is increased from 10 cm to 15 cm, so that the cold air 420 can cool the vertical wind direction plate 320 as compared with the example shown in FIG. 8A. The height of the passing area is improved from 8.3 cm to 7.4 cm. As a result, the amount of the cool air 420 passing through the upper and lower wind direction plates 320 is reduced by about 10% as compared with the example shown in FIG.

  FIG. 8C shows an example in which the interval at which the vertical wind direction boards 320 are provided is 10 cm, the length of the vertical wind direction boards 320 is 20 cm, and the angle of the vertical wind direction plates 320 with respect to the horizontal plane is 10 degrees. . In the case shown in FIG. 8C, by increasing the length of the vertical wind direction plate 320 from 15 cm to 20 cm, compared with the example shown in FIG. The height of the region to be improved improves from 7.4 cm to 6.5 cm. As a result, the amount of the cool air 420 that passes through the upper and lower wind direction plates 320 is reduced by about 21% as compared with the example illustrated in FIG.

  As described above, the amount of the cool air 420 that passes through the vertical wind direction plate 320 decreases in proportion to the length of the vertical wind direction plate 320 becoming longer. Similarly, as the length of the left and right wind direction plates increases, the amount of cold air 420 passing through the left and right wind direction plates decreases. In the direct blowout type air conditioner 10 according to one embodiment of the present invention, the length of the vertical wind direction plate 320 is 10 cm or more. Thereby, the amount of the cool air 420 passing through the vertical wind direction plate 320 is reduced. Moreover, the length of the left and right wind direction plates of the direct blow air conditioner 10 according to one embodiment of the present invention is 5 cm or more. Thereby, the amount of the cool air 420 that passes through the left and right wind direction plates is reduced.

  Here, when the length of the left and right wind direction plates 310 or the length of the upper and lower wind direction plates 320 is increased, there is a problem that the depth of the wind direction adjustment box 300 becomes longer. Therefore, as described later, it is more desirable to reduce the interval at which the left and right wind direction boards 310 or the vertical wind direction boards 320 are provided.

  FIGS. 9A to 9C are side views of the vertical wind direction plate 320 of the direct blow air conditioner 10 according to one embodiment of the present invention.

In the case shown in FIG. 9A, by narrowing the interval at which the vertical wind direction plates 320 are provided from 10 cm to 5 cm, compared with the example shown in FIG. The height of the passing area is improved from 8.3 cm to 3.3 cm.

  FIG. 9B shows an example in which the interval between the upper and lower wind direction plates 320 is 5 cm, the length of the upper and lower wind direction plates 320 is 15 cm, and the angle of the upper and lower wind direction plates 320 with respect to the horizontal plane is 10 degrees. . In the case shown in FIG. 9B, by narrowing the interval at which the vertical wind direction boards 320 are provided from 10 cm to 5 cm, compared with the example shown in FIG. The height of the region to be improved improves from 7.4 cm to 2.4 cm.

  FIG. 9C shows an example in which the interval between the upper and lower wind direction plates 320 is 5 cm, the length of the upper and lower wind direction plates 320 is 20 cm, and the angle of the upper and lower wind direction plates 320 with respect to the horizontal plane is 10 degrees. . In the case shown in FIG. 9C, by narrowing the interval at which the vertical wind direction boards 320 are provided from 10 cm to 5 cm, compared with the example shown in FIG. The height of the region to be improved improves from 6.5 cm to 1.5 cm.

  As described above, the amount of the cool air 420 that passes through the upper and lower wind direction boards 320 decreases in proportion to the decrease in the interval at which the upper and lower wind direction boards 320 are provided. The vertical wind direction plates 320 of the direct blow air conditioner 10 according to one embodiment of the present invention are provided at any intervals included between 3 cm and 7 cm. Accordingly, the amount of the cool air 420 that passes through the upper and lower wind direction plates 320 can be reduced without increasing the depth of the wind direction adjustment box 300.

  Similarly, the amount of the cool air 420 that passes through the left and right wind direction plates decreases in proportion to the narrower interval between the left and right wind direction plates. The left and right wind direction plates of the direct blow air conditioner 10 according to one embodiment of the present invention are provided at any intervals included between 1 cm and 5 cm. Thereby, the amount of the cool air 420 that passes through the left and right wind direction plates can be reduced without increasing the depth of the wind direction adjustment box 300.
