Abstract
A system () for controlling an air conditioner () includes a plurality of pressure sensors () and a controller (). Each of the pressure sensors () is positioned at an air inlet () of each of the racks (). The controller () is configured to receive pressure values from the pressure sensors () and control an airflow rate of the cooling air supplied from the air conditioner () based on the pressure values. The controller () is configured to set a target pressure value for each pressure sensor () (S), acquire a current pressure value for each pressure sensor (S), calculate a pressure drop value for each pressure sensor () between the current pressure value and the target pressure value (S), and adjust the airflow rate based on a maximum value among the plurality of the pressure drop values (Sto S).
