摘要： It is a problem of the present invention to provide an air conditioning apparatus that is capable of determining a proper quantity of refrigerant without taking too much time even when liquid refrigerant is accumulating in an accumulator at the time of refrigerant quantity determination. An air conditioning apparatus (1) is equipped with: a refrigerant circuit (10) that has an accumulator; a shut-off mechanism (38); a refrigerant detection mechanism (39); operation controlling means; refrigerant quantity determining means; liquid refrigerant accumulation determining means; and liquid refrigerant releasing means. The refrigerant detection mechanism performs detection of a state quantity relating to the quantity of refrigerant existing on the upstream side of the shut-off mechanism in a cooling operation state. The operation controlling means performs liquid refrigerant storage control. The refrigerant quantity determining means determines the properness of the quantity of the refrigerant inside the refrigerant circuit on the basis of the state quantity relating to the quantity of the refrigerant that the refrigerant detection mechanism has detected in the liquid refrigerant storage control. The liquid refrigerant accumulation determining means determines whether or not liquid refrigerant is accumulating in the accumulator. When it has been determined that liquid refrigerant is accumulating in the accumulator, the liquid refrigerant releasing means releases the liquid refrigerant from the accumulator.

摘要： An air conditioner is provided which is capable of simplifying conditions required for judging whether or not the amount of refrigerant is adequate. A refrigerant circuit (10) performs a cooling operation in which an outdoor heat exchanger (23) functions as a condenser of the refrigerant compressed in a compressor (21) and an indoor heat exchanger (42, 52) functions as an evaporator of the refrigerant condensed in the outdoor heat exchanger (23).

摘要： To provide, in a refrigerating apparatus using a refrigerant that works including a process of a supercritical state, a refrigerating apparatus whose coefficient of performance can be improved while maintaining device reliability even when its load fluctuates. A heat source-side heat exchanger (4) is connected to a discharge side of a high stage-side compression element (2d), and connecting pipes (72, 73, 74, 75) interconnect the heat source-side heat exchanger (4) and an expansion mechanism (5). Connecting pipes (77, 2a) interconnect a utilization-side heat exchanger (6) and a suction side of a low stage-side compression element (2c). A liquid-gas heat exchanger (8) causes heat exchange to be performed between the refrigerant flowing through the connecting pipes (72, 73, 74, 75) and the refrigerant flowing through the connecting pipes (77, 2a). A liquid-gas three-way valve (8C) switches between a state where it allows the refrigerant to flow in portions of the connecting pipes (72, 73, 74, 75) passing through the liquid-gas heat exchanger (8) and a state where it allows the refrigerant to flow in a liquid-gas bypass pipe (8B) that interconnects one end side and the other end side of the portions passing through the liquid-gas heat exchanger (8).
