Abstract:
Obtained is an air-conditioning apparatus that is capable of saving energy. A pressure in a passage of the second refrigerant flow switching device in which a refrigerant from an outdoor unit flows into is higher than a pressure in a passage of the second refrigerant flow switching device in which the refrigerant flows out to the outdoor unit regardless of switching states of a first refrigerant flow switching device, the second refrigerant flow switching devices, and a third refrigerant flow switching device.
