  • Air-conditioning apparatus
    Patent number: 10422547
    Abstract: An air-conditioning apparatus includes refrigerant systems that each include an outdoor unit and indoor units and that air-condition a single room, and circulators for making a temperature distribution in the room uniform. The air-conditioning apparatus determines a load on each of the two refrigerant systems in operation, and, if it is determined that improvement of operating efficiency is possible on the basis of the determination result, performs a system-selective operation in which operation of one of the refrigerant systems determined to be under a low load is stopped and the other refrigerant system determined to be under a high load is selectively performed, and causes the circulators to transport blown air blown from the indoor units of the refrigerant system determined to be under a high load to an air-conditioned zone of the refrigerant system determined to be under a low load.
