Thus, by providing the first indoor terminal 130a, the air in the machine room 200 flows from the first air outlet 133a to the first air return 134a, and a horizontal pneumatic cycle is formed in the machine room 200; by arranging the third indoor terminal 130c, the air in the machine room 200 flows from the third air outlet 133c to the third air return 134c, and a pneumatic circulation in the vertical direction is formed in the machine room 200; therefore, by arranging the first indoor terminal 130a and the third indoor terminal 130c, the inside of the machine room 200 forms a two-dimensional pneumatic cycle in the vertical direction and the horizontal direction, thereby realizing multidirectional heat dissipation of the server and improving the heat dissipation stability of the server in the machine room 200.

In other embodiments, the indoor terminals 130 may also include a first indoor terminal 130a, a second indoor terminal 130b, and a third indoor terminal 130c at the same time. Therefore, by arranging the first indoor terminal 130a, the second indoor terminal 130b and the third indoor terminal 130c, on one hand, double-dimensional pneumatic circulation in the vertical direction and the horizontal direction is formed in the machine room 200, multidirectional heat dissipation of the server is realized, and the heat dissipation stability of the server in the machine room 200 is improved; on the other hand, the simultaneous arrangement of the second indoor terminal 130b and the third indoor terminal 130c can make the upper space and the lower space of the machine room 200 well radiate heat.

In some embodiments, please refer to fig. 6 and refer to fig. 1, fig. 6 is a schematic structural diagram of a multi-split air conditioning system according to some embodiments of the present utility model. The compression system 121 includes a first compression system 121a and a second compression system 121b, the first compression system 121a and the second compression system 121b being connected in parallel between the second connection port 132 and the inlet end 111; the indoor terminals 130 include a first indoor terminal 130a, a second indoor terminal 130b, and a third indoor terminal 130c.

The first compression system 121a may be in communication with the first indoor terminal 130a, and the second compression system 121b is in communication with the second indoor terminal 130b and the third indoor terminal 130c; alternatively, the first compression system 121a communicates with the second indoor terminal 130b, and the second compression system 121b communicates with the first indoor terminal 130a and the third indoor terminal 130c; the first compression system 121a may be in communication with the first indoor terminal 130a, and the second compression system 121b may be in communication with the second indoor terminal 130b and the third indoor terminal 130c. Thus, when the first compression system 121a cannot normally operate, the second compression system 121b can normally operate, so as to ensure that the server has a certain degree of heat dissipation; when the second compression system 121b cannot normally operate, the first compression system 121a can normally operate, so as to ensure that the server has a certain degree of heat dissipation.

In still other embodiments, compression system 121 includes a first compression system 121a and a second compression system 121b, with first compression system 121a and second compression system 121b connected in parallel between second connection port 132 and inlet end 111; the indoor terminals 130 include a first indoor terminal 130a and a third indoor terminal 130c; the first compression system 121a may be in communication with the first indoor terminal 130a, and the second compression system 121b may be in communication with the third indoor terminal 130c; alternatively, the first compression system 121a may be in communication with the third indoor terminal 130c, and the second compression system 121b may be in communication with the first indoor terminal 130 a. In this way, when the first compression system 121a or the second compression system 121b cannot work normally, the cabinet 210 can still dissipate heat to a certain extent, so as to avoid the situation that the server cannot dissipate heat at all.

It should be noted that, each cabinet 210 in the machine room 200 radiates heat through the first indoor terminal 130a and the second indoor terminal 130b at the same time, so that when one of the compression systems 121 cannot work normally, the other compression system 121 can ensure that the corresponding indoor terminal 130 works normally, and the server still has a certain degree of heat radiation when one of the compression systems 121 cannot work normally.
