PROBLEM TO BE SOLVED: To obtain an air conditioner where maintainability is improved since a part of a relatively complicated refrigerant pipeline including pressure-reducing devices can be removed. SOLUTION: In an air conditioner, a service side until 100 is connected to a heat source side unit by a refrigerant pipeline, and pressure-reducing devices 75 connected to the refrigerant pipeline are accommodated in the heat source unit. By disconnecting joints 33, 40, 72 and 74 that are provided before and after the pressure-reducing devices 75, the pressure-reducing devices 75 can be removed together with a part of the refrigerant pipeline. |
