An air-conditioning apparatus comprising: a plurality of heat source units each including a compressor, a heat-source-side heat exchanger, a flow control valve, and an accumulator; a use-side load connected to the heat source units by pipes, and including a use-side heat exchanger configured to cause heat exchange to be performed between refrigerant supplied from each of the heat source units and a use-side heat medium; a controller configured to control an operation of each of the heat source units; and heat-source-side temperature detection units each configured to detect a temperature of refrigerant that flows in the heat-source-side heat exchanger of an associated one of the heat source units, wherein the controller includes a determination unit configured to determine whether or not a current operation is a non-normal operation in which the heat source units and the use-side load operate in a different manner from that in a heating operation or a cooling operation, a liquid equalization unit configured to equalize amounts of liquid refrigerant that flows in the heat source units, when the determination unit determines that the current operation is the non-normal operation, and a time measuring unit configured to measure time for which each of the heat source units operates, the determination unit is configured to determine that the current operation is the non-normal operation, when the time measured by the time measuring unit is less than a first time threshold or exceeds a second time threshold, or a temperature detected by the heat-source-side temperature detection unit is less than a temperature threshold, and the liquid equalization unit is configured to adjust the flow control valve of one of the heat source units that is determined to be in the non-normal operation by the determination unit. a plurality of heat source units each including a compressor, a heat-source-side heat exchanger, a flow control valve, and an accumulator; a use-side load connected to the heat source units by pipes, and including a use-side heat exchanger configured to cause heat exchange to be performed between refrigerant supplied from each of the heat source units and a use-side heat medium; a controller configured to control an operation of each of the heat source units; and heat-source-side temperature detection units each configured to detect a temperature of refrigerant that flows in the heat-source-side heat exchanger of an associated one of the heat source units, wherein the controller includes a determination unit configured to determine whether or not a current operation is a non-normal operation in which the heat source units and the use-side load operate in a different manner from that in a heating operation or a cooling operation, a liquid equalization unit configured to equalize amounts of liquid refrigerant that flows in the heat source units, when the determination unit determines that the current operation is the non-normal operation, and a time measuring unit configured to measure time for which each of the heat source units operates, a determination unit configured to determine whether or not a current operation is a non-normal operation in which the heat source units and the use-side load operate in a different manner from that in a heating operation or a cooling operation, a liquid equalization unit configured to equalize amounts of liquid refrigerant that flows in the heat source units, when the determination unit determines that the current operation is the non-normal operation, and a time measuring unit configured to measure time for which each of the heat source units operates, the determination unit is configured to determine that the current operation is the non-normal operation, when the time measured by the time measuring unit is less than a first time threshold or exceeds a second time threshold, or a temperature detected by the heat-source-side temperature detection unit is less than a temperature threshold, and the liquid equalization unit is configured to adjust the flow control valve of one of the heat source units that is determined to be in the non-normal operation by the determination unit.
