Air-conditioning apparatus

An air-conditioning apparatus comprising:

• a plurality of heat source units each including a compressor, a heat-source-side heat exchanger, an accumulator, and a fan configured to supply air to the heat-source-side heat exchanger;
• an imbalance detection unit configured to detect an imbalance in liquid refrigerant amount between the accumulators;
• a heat exchange amount calculation unit configured to calculate a total heat exchange amount in the heat-source-side heat exchangers;
• and
• a control unit configured to, when the imbalance detection unit detects an imbalance, perform liquid refrigerant equalization control to correct the imbalance,
• the control unit including
• a first liquid refrigerant equalization control unit configured to control an output of the fan to perform the liquid refrigerant equalization control, and
• a second liquid refrigerant equalization control unit configured to control a frequency of the compressor to perform the liquid refrigerant equalization control,
• the control unit being configured to select the first liquid refrigerant equalization control unit to perform the liquid refrigerant equalization control when a value calculated by the heat exchange amount calculation unit is within a predefined acceptable range, and select the second liquid refrigerant equalization control unit to perform the liquid refrigerant equalization control when the value calculated by the heat exchange amount calculation unit is outside the acceptable range.
