Publication number: 20070193287Abstract: An air conditioner has a heat exchanger, an absorbing agent, and a controller. The absorbing agent performs an absorbing operation for absorbing moisture in passing air flowing through the heat exchanger functioning as an evaporator and a regenerating operation for desorbing moisture from passing air heated by the heat exchanger functioning as a condenser. The controller performs control such that the absorbing operation and the regenerating operation are switched at a predetermined switching time interval. The controller also performs control of a capacity of a compressor and control for changing the predetermined switching time interval such that a predetermined load out of a total heat load, which is the sum of the latent heat load and the sensible heat load, is preferentially processed.Type: ApplicationFiled: March 25, 2005Publication date: August 23, 2007Applicant: Daikin Industries, Ltd.Inventors: Satoshi Ishida, Nobuki Matsui, Tomohiro Yabu
