Abstract:
1. An air conditioning controlling device in an air conditioning system comprising a plurality of variable air volume units for controlling, depending on a load status of a controlled area, a plurality of air volumes of supply air provided to a plurality of controlled areas from an air conditioner, the air conditioning controlling device comprising: a supply air temperature controller controlling a temperature of supply air provided by the air conditioner so that a supply air temperature measurement value will match a supply air temperature setting value; an air volume insufficiency evaluator evaluating whether or not an air volume is insufficient relative to a required air volume based on either a total air volume value, which is a sum of the air volumes supplied to the respective variable air volume units, or a CO a supply air temperature setting device changing the supply air temperature setting value in a direction wherein the variable air volume unit increases the air volume, when the air volume insufficiency evaluator has evaluated the air volume to be insufficient, wherein: when the air conditioner is blowing cold air with a temperature lower than a room temperature of the controlled area, the direction in which the variable air volume unit increases the air volume is a direction in which the supply air temperature setting value increases; and when the air conditioner is blowing hot air with a temperature higher than the room temperature of the controlled area, the direction in which the variable air volume unit increases the air volume is a direction in which the supply air temperature setting value decreases.
