In this embodiment, the width direction of the housing 110 is the left and right sides, the longitudinal direction of the housing 110 is the front and rear sides, and the outer region is the rear side, and the inner region is the front side. It is also considered that the rear shell 112 is a sheet metal part and has high strength. Therefore, the horizontal compressor 160 is disposed inside the rear shell 112, that is, the horizontal compressor 160 is disposed on the second sub Cavity.

The integrated air conditioner 100 further includes a second motor 141. The second motor 141 is provided at one end of the cross-flow wind wheel 140 and connected to the cross-flow wind wheel 140. In addition, the integrated air conditioner 100 further includes a liquid storage tank 170. The liquid storage tank 170 is disposed in the outer region and is located between the horizontal compressor 160 and the second motor 141. By placing the liquid storage tank 170 between the horizontal compressor 160 and the second motor 141, the space inside the housing 110 is fully utilized, which is beneficial to reduce the volume of the integrated air conditioner 100, while In this way, the connection distance between the horizontal compressor 160 and the indoor heat exchanger 120 is shortened.
