AIR CONDITIONING SYSTEM

To provide an air conditioning system which prevents frosting occurrence in a cooler, and can accurately adjust the temperature and humidity of air, and effectively reduce energy required for dehumidification and humidification.SOLUTION: A first adjustment passage 10A and a second adjustment passage 10B are interposed in parallel arrangement between an introduction passage 9 and a delivery passage 8. A dehumidifier 11 and a cooler 15 are arranged in the first adjustment passage 10A, and a heater 20 and a humidifier 21 are arranged in the second adjustment passage 10B. A control device C executes parallel adjustment operation of adjusting an output each of the dehumidifier 11, the cooler 15, the heater 20 and the humidifier 21 so that due to the confluence of air A led out from the first adjustment passage 10A to the delivery passage 8, and air A led out from the second adjustment passage 10B to the delivery passage 8, a temperature ts and a humidity hs of the air A fed from the delivery path 8 become a target feed temperature tsm and a target feed humidity hsm.SELECTED DRAWING: Figure 3 【課題】冷却器での霜付き発生を防止し、空気の温度，湿度を精度良く調整でき、また、除湿や加湿に要するエネルギを効果的に低減できる空調システムを提供する。【解決手段】導入路９と送出路８との間には、第１調整路１０Ａと第２調整路１０Ｂとが、並列配置で介装され、第１調整路１０Ａには、除湿器１１及び冷却器１５が配置され、第２調整路１０Ｂには、加熱器２０及び加湿器２１が配置され、制御装置Ｃは、第１調整路１０Ａから送出路８に導出される空気Ａと、第２調整路１０Ｂから送出路８に導出される空気Ａとの合流により、送出路８から送出される空気Ａの温度ｔｓ及び湿度ｈｓが目標送出温度ｔｓｍ及び目標送出湿度ｈｓｍになる状態に、除湿器１１、冷却器１５、加熱器２０、加湿器２１夫々の出力を調整する併行調整運転を実施する。【選択図】図３
