Abstract
An air-conditioning apparatus includes an outdoor unit, indoor units, and a relay unit, and forms a refrigerant circuit. The air-conditioning apparatus further includes a fourth flow control device that regulates the flow rate of refrigerant flowing into the heat source unit-side heat exchanger, a switching valve that regulates the flow rate of the refrigerant passing through a bypass pipe, and a control unit that controls the first heat-source-unit flow control device and the switching valve based on a pressure on a refrigerant inlet side of the heat source unit-side heat exchanger, an inlet temperature and an outlet temperature of a medium passing through the heat source unit-side heat exchanger, and the ratio of a cooling operation capacity to a heating operation capacity of the use-side heat exchangers.
