In this case, the air conditioning control system 1000 of the server room is controlled by the air conditioning control method (S1000) of the server room of FIG.

The server room air conditioning control method (S1000) of FIG. 9 differs from the air conditioning control method (S1000) of the server room of FIG. 8 in the method of implementing the air conditioning flow rate variable step.

Specifically, when the control unit 1090 determines that the air conditioner status information of the abnormal server rack 100 is equal to or higher than the preset upper limit status information after the step S1400 of determining whether the abnormal server rack 100 is in a high temperature state The control unit 1090 increases the rotational speed of the inlet fan driving motor 1070 provided in the cold aisle 200 of the abnormal server rack 100 and at the same time increases the rotational speed of the abnormal server rack 100, The outflow fan driving motor 1080 and the outflow fan driving motor 1080 are separately controlled so as to increase the rotational speed of the outflow fan driving motor 1080 provided in the outflow fan 300 in operation S1530.

On the other hand, when the control unit 1090 determines that the air conditioner status information of the abnormal server rack 100 is less than the predetermined upper limit status information, the control unit 1090 controls the air conditioner status information of the abnormal server rack 100 (I.e., whether or not the abnormal server rack 100 is in a supercooled state) (S1600).

When the control unit 1090 determines that the air conditioner status information of the abnormal server rack 100 is equal to or less than the predetermined lower limit status information, the control unit 1090 determines whether the abnormal server rack 100 is in the cold aisle The rotational speed of the outlet fan driving motor 1080 provided in the heating server rack 100 of the abnormal server rack 100 may be decreased while reducing the rotational speed of the inlet fan driving motor 1070 of the abnormal server rack 100 The outflow fan driving motor 1080 and the outflow fan driving motor 1080 are separately controlled (S1730) (S1740).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated that one embodiment is possible.

Accordingly, the true scope of the present invention should be determined by the technical idea of the claims.
