PROBLEM TO BE SOLVED: To reduce a refrigerant amount stored in a high-pressure side communication pipeline 151 in wholly cooling operation, and reduce a refrigerant amount necessary in operation of an air conditioning device 10, in the air conditioning device 10 in which a refrigerant circuit 14 performing a refrigeration cycle is constituted by connecting an outdoor unit 11 and a plurality of indoor units 12 with communication pipelines 151, 152.SOLUTION: A refrigerant circuit 14 is configured such that in a wholly cooling operation in which all indoor units 12 perform cooling, gas-liquid two-phase high-pressure refrigerant flows in a communication pipeline 151 on a high pressure side, and liquid refrigerant separated from the gas-liquid two-phase refrigerant is supplied to the indoor units 12.SELECTED DRAWING: Figure 2 |
