PROBLEM TO BE SOLVED: To provide an operation method of an air conditioner capable of early detecting and determining a minimum opening of an expansion valve at a proper timing.SOLUTION: In an air conditioner 10, reference opening determination control is implemented to indoor expansion valves 41A-41G belonging to a first group, and then a reference opening determination control is implemented to indoor expansion valves 41H-41N belonging to a second group, continuously without stopping the compressor 21. Here, the reference opening determination control is implemented by setting a second evaporation temperature target value Tet2 different from a first evaporation temperature target value Tet1 applied in the reference opening determination control to the indoor expansion valves 41A-41G belonging to the first group.SELECTED DRAWING: Figure 5 |
