Variable air volume air conditioning system

摘要

PROBLEM TO BE SOLVED: To provide a variable air volume type air conditioning system capable of approaching a relation between an air supply temperature set value and a total amount of required air volume to a rational range of controlling operation in view of an energy saving merely by adding minimum correction to a present air conditioning system.SOLUTION: A zone controller 17 is operated in such a way that a temperature difference ratio with a value of variation for decreasing or increasing a supplied air temperature set value during cooling time or heating time on the basis of a difference between a room temperature measured value and a room temperature set value and an operation mode being applied as a standard value is calculated for every one of a plurality of variable air volume units, its average value is calculated as an average value of a temperature difference ratio, the corrected value of the air supplying temperature set value is calculated at an air conditioner controller 19 and then the air supplying temperature set value is calculated on the basis of the corrected value of the air supplying temperature set value.
