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.
