VAV AIR-CONDITIONING SYSTEM AND AIR-CONDITIONING CONTROL METHOD

To achieve air conditioning control with faster response.SOLUTION: A VAV air-conditioning system includes: a data extraction unit 61 that extracts, in data on total airflow requests of past air conditioning and the number of revolutions of a fan, such data that includes no or almost no VAV unit 1 whose static pressure balance information indicates insufficient static pressure; a relational expression derivation unit 62 that derives a relational expression between the total airflow requests and the number of revolutions of the fan on the basis of the extracted data; and a relational expression updating unit 63 that updates the relational expression between the total airflow requests and the number of revolutions of the fan, which is set in a central system 5, to a relational expression derived by the relational expression derivation unit 62.SELECTED DRAWING: Figure 3 【課題】空調制御の速答性を向上させる。【解決手段】ＶＡＶ空調システムは、過去の空調の総要求風量とファン回転数のデータから、静圧過不足情報が静圧不足を示しているＶＡＶユニット１の台数が０台または０台近傍のデータを抽出するデータ抽出部６１と、抽出されたデータに基づいて総要求風量とファン回転数との関係式を導出する関係式導出部６２と、中央システム５に設定されている、総要求風量とファン回転数との関係式を、関係式導出部６２によって導出された関係式に更新する関係式更新部６３とを備える。【選択図】 図３
