Since the shapes and sizes of b and 16c are the same, the cleaning filter can be shared by different installation locations even when the location of the cleaning filter is changed as required.

In the above description, the indoor heat exchanger 18 is divided on the premise that the demand for the downsizing of the indoor unit 10 is satisfied, and the configuration in which the area which has been the dead space in the past is effectively used has been described. When such a request is small, it goes without saying that the number of the cleaning filters 16 may be increased by appropriately increasing the size of the indoor unit without dividing the indoor heat exchanger 18.

Further, when a plurality of cleaning filters 16 are provided, the air intake efficiency increases and the air conditioning efficiency decreases, so that it is necessary to prioritize the air conditioning efficiency over the cleaning efficiency depending on the condition of the room to be used. Is the cleaning filter 1
6a or the cleaning filter 16b alone may be used.

Of course, the cleaning filter 16a and the cleaning filter 16c may be provided side by side, and the cleaning filter 16b
And a cleaning filter 16c.
