<p><P>PROBLEM TO BE SOLVED: To provide a low dew point air-conditioning system capable of shortening the time required to lower the dew point at the treatment outlet. <P>SOLUTION: The position at which return air is turned back is optimized by installing treated air dew point meters 19, 29, and 39 for measuring the treated air upstream of dehumidification rotors 14, 24, and 34 and a dew point meter 49 for measuring the return air to be turned back to a return path 48 from a low dew point chamber 42; constantly monitoring the dew point T1, T2, T3, and TR by a switching controller 54, comparing the dew point of the treated air upstream of the respective dehumidification rotors and the dew point of the return air, and switching the opening and closing dampers 16, 26, and 36 in accordance with the dew point. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
