Abstract

An air conditioning system disclosed in the present application includes an air conditioner configured to send cooling air to a space installed with racks for mounting one or more electronic devices, an opening panel configured to supply into the space the cooling air sent by the air conditioner, and an opening control unit configured to control the opening panel to shift, every predetermined time, the region supplied with the cooling air.

Claims

1. An air conditioning system comprising:

an air conditioner configured to send cooling air to a space installed with racks for mounting one or more electronic devices, each of the electronic devices taking in air from a predetermined surface thereof and discharges air from a surface thereof opposite to the predetermined surface;

an opening panel configured to supply into the space the cooling air sent by the air conditioner; and

an opening control unit configured to control the opening panel to shift, every predetermined time, a position of a region in the space supplied with the cooling air.

2. The air conditioning system according to claim 1, wherein the opening control unit controls opening and closing of the opening panel to shift, every the predetermined time, the position of the region supplied with the cooling air.

3. The air conditioning system according to claim 1, wherein the opening control unit controls a blow-off direction of the opening panel to shift, every the predetermined time, the position of the region supplied with the cooling air.

4. The air conditioning system according to claim 1, wherein the opening control unit controls the opening panel to shift, every time less than the time taken for an exhaust air temperature of the electronic devices to rise to a predetermined temperature, the position of the region supplied with the cooling air.

5. An air conditioning control method performed by an air conditioning control system having an air conditioner configured to send cooling air to a space installed with racks for mounting one or more electronic devices, each of the electric devices taking in air from a predetermined surface thereof and discharges air from a surface thereof opposite to the predetermined surface, an opening panel configured to supply into the space the cooling air sent by the air conditioner, and an opening control unit configured to control the opening panel, the air conditioning control method comprising:

controlling the opening panel to shift by the opening control unit, every predetermined time, a position of a region in the space supplied with the cooling air.

6. The method for air conditioning control according to claim 5, further controlling the opening panel to shift by the opening control unit, every predetermined time, an amount of the cooling air supply to the region in the space.
