AIR CONDITIONING SYSTEM

To provide an air conditioning system which estimates the amount of solar radiation as accurately as possible while taking influences of shade which is generated according to time into account, and is capable of appropriately correcting distribution of air temperatures in a perimeter zone based on the amount of solar radiation.SOLUTION: A floor vicinity temperature at each position in a perimeter zone P is estimated based on a plurality of parameters relating to the floor vicinity temperatures in the perimeter zone P and based on the estimated floor vicinity temperature, a blowout air volume of an air volume change device 5 opposed to the perimeter zone P is adjusted. The floor vicinity temperature is estimated using at least the amount of solar radiation as a parameter. During a shade time which is set as a time in which the shade is generated in a pyrheliometer 100, the amount of solar radiation is grasped as an estimate in which the amount of solar radiation is calculated based on the total amount of out-of-atmospheric solar radiation and during the other time, on the other hand, it is grasped as an actually measured value in the pyrheliometer 100.SELECTED DRAWING: Figure 3 【課題】時刻により生じる日影の影響を考慮し、日射量を極力正確に推定し、これに基づいてペリメータゾーンにおける空気温度の分布を好適に是正し得る空調システムを提供する。【解決手段】ペリメータゾーンＰの床近傍温度に関連する複数のパラメータに基づき、ペリメータゾーンＰの各位置における床近傍温度を推定し、推定された床近傍温度に基づき、ペリメータゾーンＰに面する変風量装置５の吹出風量を調整するよう構成する。前記床近傍温度の推定は、少なくとも日射量をパラメータとして用いて行い、前記日射量は、日射計１００に日影の生じる時間として設定された日影時間においては、大気外全天日射量に基づき日射量の算出された推定値として把握する一方、それ以外の時間においては、日射計１００における実測値として把握する。【選択図】図３
