Description

The present invention relates to an air conditioning system of the computer room to be used in the data center or the like.

Conventionally, computer devices such as server devices are generally housed in racks and installed collectively in a computer room. As a computer room, a plurality of racks arranged in a row are supported. It has a double floor that allows ventilation and is separated from the external space by walls and ceilings. As such an air conditioning system for a computer room, a large air conditioner is generally used (see, for example, Patent Document 1).
In the air conditioning system described in Patent Document 1, an air conditioner is provided outside the computer room, and cool air from the air conditioner is caused to flow between the double floor and the floor slab, and is also calculated from the double floor. A system is adopted in which cold air is sent to the equipment by blowing it into the cabin. A rack on which equipment is mounted, for example, supplies cool air from the front and exhausts it from the back. The air thus exhausted after cooling the equipment is sucked into the air conditioner through the space above the rack and the back of the ceiling, cooled again, and then circulated to the computer room through the double floor. It is like that.

For example, in the first embodiment, the cooling panel P as the cooling means is installed facing the rack back surface R2 which is the other side of the computer rack R. However, the cooling means is a rack which is on one side of the computer rack R. You may install facing the front surface R1. In this case, the cold air cooled by the cooling means can be immediately supplied to the computer rack R. In the above-described embodiment, the ventilation rack RF is provided inside the computer rack R, and the ventilation rack RF is used to intake and exhaust the computer rack R. However, the present invention is not limited to this. A ventilation means such as a ventilation fan may be provided in the means, and air supply and exhaust to the computer rack may be performed by the ventilation means.

  In the first embodiment, the air supply duct D1, the exhaust duct D2, and the blower fan (circulation means) F are provided in the ceiling space C1, but such an air supply duct, an exhaust duct, and a circulation means are provided. It may be provided not only in the ceiling but also in the floor slab S or in the ceiling below the floor slab S. When the computer room MR has a relatively short depth, the wall W is interposed. A duct space or the like may be provided, and an air supply duct, an exhaust duct, and a circulation means may be provided in the duct space. Further, a heat exchanger P2 connected to the cooling panel P may be provided in the ceiling space C1. Further, the cooling means is not limited to the one that cools the exhaust from the computer rack R using the refrigerant sent from the heat exchanger P2 as in the cooling panel P of the above embodiment, but the cooling means itself is heated. It may have a built-in exchanger.

In addition, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this. That is, the invention has been illustrated and described with particular reference to certain specific embodiments, but without departing from the spirit and scope of the invention, Various modifications can be made by those skilled in the art in terms of material, quantity, and other detailed configurations.
Therefore, the description limiting the shape, material, etc. disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded the limitation of one part or all of such restrictions is included in this invention.
