Abstract
An air-conditioning apparatus includes first and second outdoor units having first and second outdoor heat exchangers and first and second heat source-side degree of subcooling adjustment devices configured to adjust first and second degrees of subcooling in outlet sides of the first and second outdoor heat exchangers, respectively. First and second outdoor-side determination units are configured to determine first and second degrees of subcooling, respectively. A controller is configured to control the first and second heat source-side degree of subcooling adjustment devices, respectively, such that a difference between the first degree of subcooling and the second degree of subcooling is reduced when refrigerant is charged into a refrigerant circuit having the first outdoor heat exchanger and the second outdoor heat exchanger.
