The invention provides an integral air conditioner. The integral air conditioner comprises an air conditioner shell, and a compressor arranged in the air conditioner shell; an outer side area and an inner side area are arranged on two sides of the compressor; an outdoor air way for exhausting air to a back side plate is arranged in the outer side area; on the transverse section of an outdoor fan,the distance from the middle point of the shortest connecting line between an outer volute tongue and an outer volute shell to the back side plate is smaller than the distance from the axis of the outdoor fan to the back side plate; the midperpendicular surface of the shortest connecting line is towards the outer direction of the air conditioner shell; and an included angle with the horizontal plane in a direction from the outer side area to the inner side area is larger than or equal to 90 degrees and smaller than or equal to 180 degrees. Through the technical scheme, the total size of the air conditioner is effectively reduced, and the vibration of the compressor after installation is reduced; and as the air way structure is provided with no air outlet in a top plate and a base plate ofthe air conditioner shell, the sizes of the outer volute shell and the outer volute tongue in the height directions are reduced, and the height of the outer side area is reduced.
