The purification module can be a filter module to filter out harmful impurities in the fresh air flow. The purification module can also have other processing functions to further process the fresh air flow to make it fresher and healthier. The volute can be made closer to the first end of the length direction of the casing 10 than the purification casing (that is, the volute is located on the left side of the purification casing), so that the fresh air outlet can be arranged closer to the first end of the casing 10, so that the It does not affect the layout of the heat exchange air inlet 11, the heat exchange air outlet 12 and the evaporator and the heat exchange fan.

The impeller may be a centrifugal impeller, and the end of the volute in the thickness direction (x-axis direction) facing the purification shell is provided with a suction port. The side of the purification shell facing the volute is open, so that the cover is fastened on the volute, the edges are sealed and connected, and the inner space is communicated. The purification module is enclosed by the purification shell. Under the rotation of the impeller, the fresh air flow enters the purification shell from the fresh air inlet of the purification shell, flows through the purification module to be purified by it, and then enters the volute from the suction port. Under the action of the impeller, the purified airflow is thrown out along the radial direction of the impeller, and then discharged from the volute through the fresh air outlet.

A maintenance socket is opened at the front of the peripheral front of the purification shell to allow the purification module to be inserted into the purification shell through the maintenance socket. In this way, the user can easily clean and replace the purification module by disassembling the front panel 18 of the casing 10, which is very convenient to use.
