The main refrigerant pipe (not shown) extending from the outdoor unit is connected to the sub refrigerant pipe connection ports 52 to 55 near the indoor unit via the main refrigerant pipe connection port 51. At this time, since the pipe diameter changes in accordance with the capacity of the outdoor unit, if the diameter of the main refrigerant pipe matches the large-diameter part 51a at the main refrigerant pipe connection port 51, the main refrigerant pipe can be connected as it is, but can be connected to the large-diameter part 51a.
