AIR-CONDITIONING CONTROL DEVICE AND AIR-CONDITIONING CONTROL PROGRAM

To suppress uneven air-conditioning in an air-conditioning object space, even when distribution of heat quantity to each of air conditioning devices is uneven, in air-conditioning control by the plurality of air conditioning devices.SOLUTION: In a case when one of three outdoor units is failed, air-conditioning to all of islands can be performed by corresponding indoor units 20A-20C and indoor units 22A-22C by increasing capacities (load factors) of remaining two outdoor units in comparison with those at a normal time. In a case when two of the three outdoor units are failed, air-conditioning to all of the islands can be performed by corresponding indoor units 20A-20C by increasing the capacity (load factor) of remaining one outdoor unit in comparison with that when one outdoor unit is failed. By increasing the load factor of the operable outdoor unit to be higher than a standard time load factor and a load factor α at the failure of one unit (standard load factor×β [β>α]), an air-conditioning capacity effective area by the three outdoor units can be secured.SELECTED DRAWING: Figure 6 【課題】複数の空調装置による空調制御時に、それぞれの空調装置への熱量配分が不均一であっても、空調対象空間内の空調むらを抑制する。【解決手段】３台の室外機の内、１台が故障した場合、残りの２台の室外機の能力（負荷率）を通常時よりも大きくすることで、対応する室内機２０Ａ〜２０Ｃと室内機２２Ａ〜２２Ｃによって、全ての島への空調が可能である。３台の室外機の内、２台が故障した場合、残りの１台の室外機の能力（負荷率）を１台故障時よりも大きくすることで、対応する室内機２０Ａ〜２０Ｃによって、全ての島への空調が可能である。稼働可能な室外機の負荷率を、標準時負荷率及び１台故障時負荷率αよりも高くすることで（標準負荷率×β「β＞α」）、３台の室外機による空調能力有効エリアが確保される。【選択図】図６
