Referring to fig. 3 and 4, fig. 3 is a sectional view of the parking air conditioner of fig. 1 taken along a-a direction, and fig. 4 is a partially enlarged view of X in the sectional view of the parking air conditioner of fig. 3 taken along the a-a direction. The air-conditioning case 100 may include a mount 11, a first sealing cover 12, and a second sealing cover 13. The mounting seat 11 includes a first bottom wall 111 and a first side wall 112 enclosing the first bottom wall 111 to form a mounting cavity 15. The first bottom wall 111 may be used for being mounted and fixed on a vehicle, or the first bottom wall 111 may be used for mounting other parts of the parking air conditioner, such as a compressor, and the like, which is not limited in the embodiment of the present application. The first sealing cover 12 includes a second bottom wall 121 and a second side wall 122 enclosing the second bottom wall 121 to form the working chamber 14. The first sealing cover 12 is disposed in the mounting cavity 15, such as the second bottom wall 121 is fixedly connected to the first bottom wall 111, and/or the second side wall 122 is partially fixedly connected to the first side wall 112. The second sidewall 122 is disposed around the first sidewall 112. The second sealing cover 13 includes a top wall 131 and a third side wall 132 disposed around the top wall 131. The outer side of the third side wall 132 abuts against the first side wall 112, thereby achieving the sealing of the mounting cavity 15 by the second seal cover 13. The inner side of the third side wall 132 is provided with a first sealing rib 133, and the first sealing rib 133 is in interference fit with the second side wall 122, so that the working cavity 14 is sealed by the second sealing cover 13.
