It is understood that the casing 102 may have a rectangular parallelepiped shape, or may have other shapes, that is, the air conditioning indoor unit 100 may be designed to have different shapes according to needs.

Example two:

as shown in fig. 1 and fig. 2, according to an embodiment of the present invention, on the basis of the above embodiment, further, in the second direction, there is a gap W between two adjacent groups of heat exchangers 108.

In this embodiment, a gap W is provided between two adjacent sets of heat exchangers 108, and indoor return air can flow into the housing 102 through the gap between two adjacent sets of heat exchangers 108, so that air flow can enter each side of the heat exchangers 108, heat exchange efficiency of the heat exchangers 108 is improved, and refrigerating capacity of the heat exchangers 108 is further improved.
