[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] The embodiment of the present invention discloses an air conditioning system, as shown in the attached Figures 1 to 3 As shown, it includes a first evaporator 101, a first compressor 102, a second evaporator 201 and a second compressor 202. The first evaporator 101 and the second evaporator 201 are arranged in parallel, and both are used to evaporate the refrigerant into low-temperature and low-pressure steam by absorbing heat from the external environment to achieve refrigeration. The first compressor 102 and the second compressor 202 are arranged in parallel, and both are used to inhale the low-pressure and low-temperature steam in the connected evaporator, and convert it into high-pressure and high-temperature steam after compression to drive the operation of the refrigeration cycle system. The structures and working principles of the two evaporators and the two compressors can refer to the existing technology and will not be described in detail here.

[0044] The air conditioning system of the present invention is a dual refrigeration cycle system. When the refrigeration demand is large, the dual refrigeration cycle systems operate simultaneously; when operating at a low load, one of the dual refrigeration cycle systems is shut down and the other operates.

[0045] As attached Figure 1 As shown, the first evaporator 101 and the second evaporator 201 are respectively provided with a first inner air pipe 103 and a second inner air pipe 203 at one end, that is, the first end of the first evaporator 101 is provided with a first inner air pipe 103, and the first end of the second evaporator 201 is provided with a second inner air pipe 203. The first inner air pipe 103 and the second inner air pipe 203 are respectively connected to the first compressor 102; that is, the inner air pipes of the first evaporator 101 and the second evaporator 201 are both provided at the same end, and the inner air pipes of the two are both connected to the first compressor 102.

[0046] As attached Figure 2As shown, the other ends of the first evaporator 101 and the second evaporator 201 are respectively provided with a first external air pipe 104 and a second external air pipe 204, that is, the second end of the first evaporator 101 is provided with a first external air pipe 104, and the second end of the second evaporator 201 is provided with a second external air pipe 204. The first external air pipe 104 and the second external air pipe 204 are respectively connected to the second compressor 202; that is, the external air pipes of the first evaporator 101 and the second evaporator 201 are both provided at the same end, and the external air pipes of the two are both connected to the second compressor 202.

[0047] In the present invention, the first inner air pipe 103 and the first outer air pipe 104 are respectively arranged at the two ends of the first evaporator 101, and the second inner air pipe 203 and the second outer air pipe 204 are respectively arranged at the two ends of the second evaporator 201; and the first inner air pipe 103 and the second inner air pipe 203 are respectively arranged at the first ends of the two evaporators, and the first outer air pipe 104 and the second outer air pipe 204 are respectively arranged at the second ends of the two evaporators; it can be seen that the present invention arranges the inner air pipe and the outer air pipe of the first evaporator 101 and the second evaporator 201 at both ends, so that the inner and outer air pipes of the two evaporators are respectively connected to different compressors, thereby avoiding cross-interference between the inner and outer air pipes, making the pipeline layout clearer and more reasonable, and making it easier to find and maintain during maintenance.

[0048] As attached Figures 1 to 3 As shown, the cross-sections of the first evaporator 101 and the second evaporator 201 are both triangular. By reducing the height of the two evaporators, the height of the air-conditioning system is reduced, and the space occupied is small. Specifically, the first evaporator 101 and the second evaporator 201 are specifically isosceles triangles with the pointed end facing upward and the large end facing downward. The large end of the first evaporator 101 is opposite to the first compressor 102, and at least part of the first compressor 102 extends upward until it is embedded in the first evaporator 101; and the large end of the second evaporator 201 is opposite to the second compressor 202, and at least part of the second compressor 202 extends upward until it is embedded in the second evaporator 201; the special structure of the first evaporator 101 and the second evaporator 201 allows parts of the first compressor 102 and the second compressor 202 to be enclosed in the relative evaporators, further reducing the overall height of the air-conditioning system and reducing the space occupied.

[0049] As a preferred embodiment, as shown in the attached Figures 4 to 7As shown, the first evaporator 101 includes a first left outer tube row 1011, a first left inner tube row 1012, a first right inner tube row 1013 and a first right outer tube row 1014.

It should be noted that the angle between the second left outer tube row 2011 and the second right outer tube row 2014 is equal to the angle between the second left inner tube row 2012 and the second right inner tube row 2013.

The first evaporator 101, the first compressor 102, and the first fan 109 are fixedly mounted on the first mounting frame 110 in sequence from top to bottom, making full use of the installation space of the first mounting frame 110, improving the space utilization rate of the first mounting frame 110, making the arrangement of the first evaporator 101, the first compressor 102, and the first fan 109 more reasonable and compact, and effectively reducing the height of the first mounting frame 110. Similarly, the second evaporator 201, the second compressor 202, and the second fan 209 are fixedly mounted on the second mounting frame 210 in sequence from top to bottom, making the arrangement of the second evaporator 201, the second compressor 202, and the second fan 209 on the second mounting frame 210 more compact and reasonable, and effectively reducing the height of the second mounting frame 210.

[0056] The first electric control box 111 and the second electric control box 211 are fixedly provided on adjacent sides of the first mounting frame 110 and the second mounting frame 210, respectively, so that the first electric control box 111 and the second electric control box 211 are arranged compactly, and the wiring distance between the two electric control boxes is reduced by shortening the installation distance between the first electric control box 111 and the second electric control box 211, which is convenient for maintenance and reduces wiring costs. Specifically, the first electric control box 111 is a weak current control box, and the second electric control box 211 is a strong current control box. The first electric control box 111 and the second electric control box 211 are respectively installed on the first mounting frame 110 and the second mounting frame 210, so that the strong current and the weak current are routed separately, ensuring a more reasonable line layout and effectively reducing the difficulty of assembly and maintenance.

The first frequency converter 112 is consistent with the height of the first fan 109, and the second frequency converter 212 is consistent with the height of the second fan 209. By reasonably arranging the first frequency converter 112 and the second frequency converter 212, the installation space of the first mounting frame 110 and the second mounting frame 210 can be reasonably utilized, thereby effectively improving the space utilization rate of the first mounting frame 110 and the second mounting frame 210, further reducing the height of the first mounting frame 110 and the second mounting frame 210, and effectively reducing the occupied space. The first frequency converter 112 is connected to the first fan 109, and the first frequency converter 112 changes the air volume of the first fan 109 by adjusting the rotation speed of the first fan 109; similarly, the second frequency converter 212 is connected to the second fan 209, and the second frequency converter 212 changes the air volume of the second fan 209 by adjusting the rotation speed of the first fan 109.
