Abstract: In an air conditioner having an electrical equipment mount device containing at least one circuit board on which electrical parts connected to wires are mounted, plural wire abutting portions are formed on a wire fixing face so as to be different in height from said wire fixing face, and a wire is fixedly pinched between a wire press member and one of the wire abutting portions that is selected in accordance with the diameter of the wire. The wire fixing face has a conduit fixing member having a conduit fixing face to which one end portion of a conduit having electrical wires inserted therein is fixed. Plural engaging holes are formed in the wire fixing face, and the conduit fixing member is equipped with plural engaging members which are fixedly engageable with the engaging holes of the electrical equipment mount plate. The engaging members are located at different positions on the conduit fixing member with respect to the conduit fixing face.

Abstract: When a single room unit 4 is connected to a compressor 2B of the outdoor unit 1, the room unit 4 is connected to a connection box 29 which is mounted on the outdoor unit 1. Instead, if two room units 5A and 5B must be connected to the outdoor unit 1, a connection box 37 is mounted on the back of the outdoor unit 1. The connection box 37 has branches each having valves 44A and 44B and expansion devices 43A and 43B. The two room units are connected to these branches of the connection box 37. Because of these optional connection boxes, the outdoor unit itself may be constructed in a compact form, and connection of multiple room units to the outdoor unit may be carried out conveniently and correctly in a simple manner.
