The whole casing 100 can be round, the side air outlet 130 covers the circumferential full angle of the casing 100, and 360-degree all-directional air supply can be realized. The intake vent 110 may have a ring shape, including a circular ring shape or a polygonal ring shape. The air inlet can also be round or square. An air inlet grille 111 may be disposed at the air inlet 110.
The first heat exchanger 210 and the second heat exchanger 220 may be connected in series or in parallel in the vapor compression refrigeration cycle system (the series and parallel connection of the heat exchangers is common in the air conditioning field, and will not be described in detail here). A large number of experiments of the inventor prove that when the two heat exchangers are connected in parallel, the overall heat exchange efficiency is higher. Furthermore, when the two heat exchangers are connected in parallel, the two heat exchangers can be respectively provided with an electronic expansion valve, so that the air conditioner can independently control the flow of the two heat exchangers, and the flow of the two heat exchangers can be reasonably distributed to obtain higher energy efficiency.
In some embodiments, as shown in FIG. 1, the first heat exchanger 210 may be disposed at the bottom of the inner side of the housing 100 and opposite to the air inlet 110.

Such as a dome or arc plate, or a spherical crown plate. So that the condensed water generated during the cooling operation of the first heat exchanger 210 flows to the edge, which is convenient for the concentrated treatment of the condensed water, and the condensed water is prevented from dropping downwards through the air inlet 110. Compared with a flat plate structure, the surface area of the bent plate with the same radial dimension is larger, and the heat exchange effect is better.
As shown in fig. 1, the fan 500 may be disposed above the first heat exchanger 210 and radially inward of the second heat exchanger 220. I.e. so that the second heat exchanger 220 "surrounds" the fan 500. The fan 500 may be a centrifugal fan, an axial flow fan, a laminar flow fan, or the like.

The air inlet end of the air duct 600 is connected to the bottom wall of the casing 100, and the air outlet end is connected to the bottom edge of the fan 500, so as to introduce the air flow after heat exchange with the first heat exchanger 210 into the fan 500. The inner profile of the air duct 600 may be tapered from bottom to top in radial dimension to make its inlet end larger, facilitating the design of a larger first heat exchanger 210.
As shown in fig. 1, a first drain pan 610 may be formed at the bottom of the inner side of the air duct 600. The first water pan 610 is located below the end of the first heat exchanger 210, and is used for supporting the first heat exchanger 210 and receiving the condensate water generated by the first heat exchanger, thereby achieving two purposes.
A second drain pan 620 is formed outside the air guide duct 600. The second water pan 620 is located below the bottom end of the second heat exchanger 220, and is used for supporting the second heat exchanger 220 and receiving the condensate water generated by the second heat exchanger.
Fig. 3 is a schematic structural view of an air guide grill in the ceiling type air conditioning indoor unit shown in fig. 1. As shown in fig. 1 to fig. 3, the first air outlet portion 121 may be an air guiding grille, and specifically includes a frame 1211 and a plurality of air guiding plates 1212 rotatably mounted on the frame 1211 (for example, in fig. 3, the x axis is a rotation axis of one air guiding plate 1212). When the air conditioner operates, the plurality of air deflectors 1212 are driven to rotate synchronously, so that the lower air outlet 120 can be opened and closed, and the wind direction and the air volume of the lower air outlet 120 can be adjusted. Air guide grilles are very common in the air conditioning field, and their more detailed structure and driving manner are well known to those skilled in the art and will not be described herein.
Similarly, the second air outlet portion 131 is also an air guiding grille, and similarly has a plurality of air guiding plates parallel to each other, so that the air guiding plates rotate synchronously to open and close the side air outlet 130 or adjust the air direction and the air volume of the side air outlet 130.
