At the ends of these refrigerant pipes 23 and 25, unions 24 connected to unit piping (not shown) extending from an outdoor unit (not shown) installed outdoors are screwed. In the example, the electrical box 9 is arranged on the front panel 13 side (described in detail below), and the depth (width) W of the casing is wide by the electrical box 9.
And sufficient space for connection work is secured.

The heat exchanger 5 is disposed obliquely in the air passage 27 defined by the casing 3 and the inner panel 13d so as to reduce the noise generated by the blown air. Have been. Such a heat exchanger 5
It is arranged straight from the front panel 13 to the back, and therefore, the inclination angle is determined by the depth W of the casing. In general, the smaller the inclination angle of the heat exchanger 5 is, the smaller the wind noise is. The longer the depth W, the lower the wind noise. In this regard, in this embodiment, since the depth W of the casing is larger than that of the related art and the inclination of the heat exchanger 5 is increased by the amount of the electrical box 9, the wind noise of the wind passing through the heat exchanger 5 is reduced. Can be smaller.

A humidifier 28 is provided on the back of the heat exchanger 5 for humidifying the air to be blown, so that the room can be humidified as needed during heating or the like.

The blower 7 is a so-called centrifugal blower,
