I.e., the second duct wall 92 is arranged as a circular arc transition. Through uniform arc transition, the length 560mm of the air outlet channel 9 near the inner air outlet 12 along the direction of the rotation axis of the cross flow fan 22 is shortened to the length 410mm of the air outlet 81 along the direction of the rotation axis of the cross flow fan 22. So that the length of the panel 84 of the inner casing 8 in the direction of the rotation axis of the cross flow fan 22 can be not more than 480mm, and the installation requirements can be satisfied. In the present embodiment, as shown in fig. 7, in the projection of the plane perpendicular to the roof wall and parallel to the rotation axis of the crossflow blower 22, the arc formed by the projection of one of the second air duct walls 92 is denoted as a first arc, and the arc formed by the projection of the other second air duct wall 92 is denoted as a second arc; wherein, the circle where the first arc is located is marked as a first projection circle O₁The circle where the second arc is located is marked as a second projection circle O₂(ii) a First projection circle O₁And the second projection circle O₂And (4) separating.

Meanwhile, the limitation of the size of the opening of the car roof to the sizes of the cross flow fan 22 and the evaporator 21 is broken, and the refrigeration efficiency and the air supply quantity of the parking air conditioner 100 are effectively improved. In addition, the air volume loss of the air flow when passing through the air outlet channel 9 is not more than 15%, the large air volume is effectively ensured, the air speed at the air supply outlet 81 is improved, the air supply distance is increased, and the user experience is improved.

The depth of the water pan 4 is set to 20 mm-30 mm, so that the water stored in the water pan 4 can be effectively prevented from splashing in the vibration process of the vehicle. In this embodiment, the depth of the water pan 4 is 20 mm.

The drip tray 4 comprises a bottom wall 40, and a first side wall 41, a second side wall 42, a third side wall 43 and a fourth side wall 44 which are sequentially connected end to end around the bottom wall 40.
