The filtered air enters the space where the compressor module 23 is located, so as to adjust the air temperature and control the humidity. Finally, the fresh air is discharged by the indoor air supply fan 24. The indoor air enters the indoor return air chamber 16 from the indoor return air inlet 13, and the air enters the exchange port from the interlayer space at the bottom of the chassis 1 to the location of the outdoor exhaust fan 25, and the indoor air is discharged through the outdoor exhaust fan 25. In this way, the fresh air circulation is realized.

[0040] In this plan, the focus is on the maintenance of functional modules, and the circulation principle of the above fresh air system is only briefly explained.

[0041] Specifically, a plurality of inspection openings and inspection doors are provided on one side of the long side of the box body of the present solution, and the inspection module 2 is slidably taken out from the inspection opening of the box body.

[0042] Combination Figure 3 , Figure 4 and Figure 5 Optionally, the inspection port includes a left inspection port 31, a control box 6 is fixed on the left inspection port 31, a flange 61 is provided on the control box 6, and the flange 61 is fixed to the edge of the left inspection port 31 by bolts. The left inspection port 31 is connected to the left inspection door 32 through a hinge 8, and the left inspection door 32 is used to close the left inspection port 31. The hinge 8 is a latch structure. The installation position of the control box 6 is convenient for maintenance personnel to open the left inspection door 32 to observe and inspect this part.

[0043] In order to install the outdoor exhaust fan 25 and the indoor supply fan 24 at the middle level, an overhead design is implemented through the support rail 7, and the support rail 7 is used to realize the pulling and disassembly operation. The chassis 1 is provided with the support rail 7, and the outdoor exhaust fan 25 is fixed to the support rail 7 by bolts. After the bolts are removed, the outdoor exhaust fan 25 slides with the support rail 7 and is taken out from the left inspection port 31.

[0044] The inspection port also includes a central inspection port 41. A bracket 17 for horizontal sliding of the exchange core module 21 and the filter module 22 is provided in the box body. The central inspection port 41 allows the exchange core module 21 and the filter module 22 to be horizontally withdrawn. A seal 9 is fixed at the central inspection port 41 by bolts. The seal 9 is a metal sheet and can be fixed by screws. The seal 9 can prevent the exchange core module 21 from detaching from the chassis 1.
