Through detailed tests and numerical simulations, the inventor discovered that "a sufficient amount of cool air is difficult to be supplied into the server room from a specific air outlet among a plurality of air outlets." In view of the above points, the present disclosure discloses an example of a server room structure capable of supplying a sufficient amount of cold air from the specific air outlet.

The structure of the server room in which the equipment for information and communication technology is installed is, for example, a ceiling member (12) that is provided above the equipment for information and communication technology and constitutes a part of the cold air duct (10) through which cool air flows. a ceiling member (12) provided with a plurality of air outlets (11) for blowing cold air, and among the plurality of air outlets (11), at least an air outlet (11A) located at the most upstream position in the air flow, A guide member (13) for guiding the cool air to the upper side of the information and communication technology equipment is provided, and the guide member (13) is located at the outer edge portion (11B) of the outer edge portion of the outlet (11A) located upstream of the air flow. ) downward.

As a result, the ceiling member (12) and the guide member (13) are continuously connected at the outer edge located upstream in the air flow. For this reason, when the cold air that circulates while adhering to the ceiling member (12) reaches the outer edge, it circulates along the guide member (13) due to the Coanda effect and is supplied into the server room.

At this time, the cooling air flowing around the cooling air is drawn in by the cooling air flowing along the guide member (13) due to the entrainment action of the cooling air flowing along the guiding member (13). Therefore, in addition to the cold air flowing along the guide member (13), the cold air drawn by the cold air is also supplied to the server room. Therefore, a sufficient amount of cool air can be supplied to the server room.

By the way, the flow velocity of the cold air flowing through the cold air duct (10) becomes smaller toward the downstream side of the air flow due to the ventilation resistance in the cold air duct (10). That is, among the cold air flowing through the cold air duct (10), the flow velocity of the cold air passing over the air outlet (11A) located at the most upstream position in the air flow is equal to the flow velocity of the cold air passing through the other air outlets (11). big compared to

For this reason, when the differential pressure between the air pressure on the upstream side of the air flow in the cold air duct (10) (hereinafter referred to as duct internal pressure) and the air pressure in the server room (hereinafter referred to as server room pressure) becomes small, or when the duct A case may occur in which the internal pressure becomes lower than the server room pressure.

Then, when the differential pressure becomes small, a sufficient amount of cool air cannot be supplied to the server room. Furthermore, when the duct internal pressure becomes lower than the server room pressure, the air in the server room flows back into the cold air duct (10).

That is, the above-mentioned "specific air outlet" is an air outlet including at least "the air outlet (11) positioned most upstream in the air flow". In other words, the above-mentioned "specific outlet" includes "a outlet where the differential pressure between the duct internal pressure and the server room pressure is small" or "an outlet where the duct internal pressure is lower than the server room pressure". It is the outlet.

Cool air is supplied from each outlet 11 to the cooling air passage 3A. Both ends of the cooling air passage 3A in the extending direction of the rack rows R are closed with closing members 3C.

A partition member (not shown) is provided on the ceiling side of each rack row R to separate the cooling air passage 3A from the passage 3B (see FIG. 1). Therefore, as shown in FIG. 1, cold air supplied from the cold air duct 10 to the cooling air passage 3A passes through each rack row R and flows to the passage 3B on the side opposite to the cooling air passage 3A.

The passage 3B is not provided with a cool air outlet. For this reason, the air whose temperature has risen after completing heat exchange with the ICT equipment flows through the passage 3B. That is, the passage 3B serves as a hot air passage (hot aisle) through which heated air (warm air) flows.

At least one air conditioner AC is installed on one end side of the rack row R in the extending direction. The air conditioner AC supplies cold air to the cold air duct 10 . A first space in which the air conditioner AC is installed is separated from a second space in which the ICT equipment 2 is installed via the wall portion 5 .

The following description is for the ceiling panel 12 mounted at one end in the extending direction of the rack row R, that is, at the position closest to the suction port 5A among the plurality of ceiling panels 12 .

The ceiling panel 12 includes at least a panel body 12A, a guide member 13, and the like, as shown in FIG. The panel main body 12A constitutes a part of the lower body of the cold air duct 10 and is a member that partitions the inner space of the cold air duct 10 from the first space.

At least one (in this embodiment, a plurality of) outlets 11 are provided in the panel main body 12A. Hereinafter, the outlet 11 positioned most upstream in the air flow (the outlet 11 positioned on the right end side in FIG. 3) among the plurality of outlets 11 is referred to as an upstream outlet 11A.

A guide member 13 is provided at an outer edge portion (a right end outer edge portion in FIG. 3) 11B positioned upstream of the air flow among the outer edge portions of the upstream outlet 11A. The guide member 13 extends downward from the outer edge portion 11B when cold air is supplied from the upstream outlet 11A to the ICT device 2 side.

A wind guide member 14 is provided at an outer edge portion (a left end outer edge portion in FIG. 3) 11C located downstream of the air flow among the outer edge portions of the upstream outlet 11A. The air guide member 14 extends upward from the outer edge portion 11C when supplying cool air to the ICT device 2 from the upstream outlet 11A.

As a result, the cold air flowing through the cold air duct 10 is guided to the upstream outlet 11A. Of the air outlets 11 provided in the ceiling panel 12 (panel main body 12A), the air outlet 11 (hereinafter referred to as the downstream air outlet 11) located downstream of the upstream air outlet 11A is also provided with the air guide member 15. is provided.

Each wind guide member 15 is provided at an outer edge portion of each downstream blower outlet 11 positioned downstream of the air flow. When the cool air is supplied from the downstream outlet 11 to the ICT device 2 side, the air guide member 15 extends upward from the outer edge portion, similarly to the air guide member 14 .

The guide member 13 and the air guide members 14 and 15 according to this embodiment can swing with respect to the panel main body 12A, as shown in FIGS. FIG. 4 shows a state in which the guide member 13 and the air guide members 14 and 15 have been displaced to the positions where the respective outlets 11 are closed.

FIG. 5 shows a state in which the guide member 13 and the air guide members 14 and 15 are displaced to the position where each blowout port 11 is fully opened. In this embodiment, the guide member 13 and the air guide members 14 and 15 are displaced in conjunction with each other.
