Abstract

In a conventional duct-type air conditioning system, a total required air volume of the entire system is decided by a variable air volume (VAV) control unit and control of a damper opening degree and control of the number of revolutions of an air blower are executed, in order to maintain the room temperature in the air-conditioned spaces at a set temperature. An air volume is finely adjusted based on the damper opening degree and a change amount of the total required air volume. However, the VAV control unit has a complicated configuration such that information required for air conditioning control, such as excess and deficiency information of static pressure and damper opening degree information, are acquired and the pieces of information are fed back to the control of the air conditioner. Therefore, the system becomes expensive as a whole and the system is not easy to be widely used in general houses. Further, in the conventional technique, an air volume is adjusted by a damper opening degree, and thus it is required that a damper to be used can finely control the opening degree. Accordingly, the cost of the entire system increases. Disclosed herein is a duct-type air conditioning system having: an air conditioner; a plurality of dampers respectively provided in a plurality of ducts provided corresponding to a plurality air-conditioned spaces, to which conditioned air from the air conditioner is supplied, to bring an air trunk in each of the ducts into an opened state or closed state individually; a plurality of outlets respectively provided at ends of the ducts; and a control device that controls the air conditioner and the dampers, wherein the control device includes a controlled air-volume calculation unit that, when the air conditioner performs automatic air volume adjustment, calculates a controlled air volume of an indoor unit constituting the air conditioner, on the basis of: an opening ratio, which is a ratio of sum of numbers or areas of opened outlets provided in the duct having the damper in an opened state with respect to sum of numbers or areas of the outlets respectively provided in the air-conditioned spaces; and a temperature difference between a target temperature of the air-conditioned space and a temperature measured in the air-conditioned space where the opened outlet is present.
