摘要: An air conditioning apparatus has plural indoor units having: plural heat exchangers; and flow controllers respectively corresponding to the heat exchangers. In each of the indoor units, one heat exchanger is used as a condenser, and another heat exchanger is used as an evaporator, thereby causing the indoor unit to perform a temperature and humidity controlling operation. An indoor unit(s) which is not set to perform the temperature and humidity controlling operation may be caused to perform a heating operation or a cooling operation. Capacity controls on the condensers and the evaporators are performed by corresponding flow controllers. Gas refrigerants ejected from plural heat exchangers serving as evaporators are joined together, and then distributed to plural heat exchangers serving as condensers.
