Abstract: A system (20) for controlling an air conditioner (12) includes a plurality of pressure sensors (19) and a controller (13). Each of the pressure sensors (19) is positioned at an air inlet (15) of each of the racks (11). The controller (13) is configured to receive pressure values from the pressure sensors (19) and control an airflow rate of the cooling air supplied from the air conditioner (12) based on the pressure values. The controller (13) is configured to set a target pressure value for each pressure sensor (19) (S300), acquire a current pressure value for each pressure sensor (S401), calculate a pressure drop value for each pressure sensor (19) between the current pressure value and the target pressure value (S402), and adjust the airflow rate based on a maximum value among the plurality of the pressure drop values (S403 to S410).

Abstract: A power identification device at least includes a measurement information acquisition unit for acquiring the amount of power generation by a power producer and the amount of power consumption by a consumer respectively as measurement information, a rule management unit for managing a generation rule for generating attribute information, a distribution rule and a loss rule for distributing the attribute information to the consumer, the attribute information containing a primary attribute related to each of the amount of power generation and the amount of power consumption and an additive attribute related to the amount of power generation, an attribute computation unit for generating the attribute information from the measurement information based on the generation rule and distributing the attribute information from the power producer to the consumer based on the distribution rule and the loss rule, and an attribute output (visualization) unit for outputting the attribute information to the outside.
