Abstract:
An air-conditioning apparatus includes a refrigerant circuit in which pipes sequentially connect a compressor, a flow switching device, a heat source side heat exchanger, an expansion device, a load side heat exchanger, and the flow switching device, and configured to perform a cooling operation and a heating operation switched by the flow switching device, an oil separator configured to separate refrigerating machine oil from refrigerant discharged from the compressor, a first bypass passage in which fluid flowing out of the oil separator flows, an auxiliary heat exchanger configured to cool the fluid, a first flow control device configured to control passing of the fluid, a second bypass passage in which liquid refrigerant or two-phase gas-liquid refrigerant flowing through one of the pipes connecting the heat source side heat exchanger and the expansion device flows, and a second flow control device configured to control passing of refrigerant.

Claim (Index 1):
An air-conditioning apparatus comprising:\n a refrigerant circuit in which pipes sequentially connect a compressor, a flow switching device, a heat source side heat exchanger, an expansion device, a load side heat exchanger, and the flow switching device, and configured to perform a cooling operation and a heating operation switched by the flow switching device, the cooling operation being an operation in which a discharge side of the compressor is connected to the heat source side heat exchanger and a suction side of the compressor is connected to the load side heat exchanger, the heating operation being an operation in which the discharge side of the compressor is connected to the load side heat exchanger and the suction side of the compressor is connected to the heat source side heat exchanger; an oil separator disposed in one of the pipes connecting a discharge unit of the compressor and the flow switching device, and configured to separate refrigerating machine oil from refrigerant discharged from the compressor; a first bypass passage connected to an oil outflow side of the oil separator and a suction unit of the compressor, and in which fluid flowing out of the oil separator flows; an auxiliary heat exchanger disposed in the first bypass passage, and configured to cool the fluid; a first flow control device disposed in the first bypass passage, and configured to control passing of the fluid; a second bypass passage connected to one of the pipes connecting the heat source side heat exchanger and the expansion device and to one of the pipes connecting the suction unit of the compressor and the flow switching device, and in which liquid refrigerant or two-phase gas-liquid refrigerant flowing through the one of the pipes connecting the heat source side heat exchanger and the expansion device flows; and a second flow control device disposed in the second bypass passage, and configured to control passing of refrigerant; a discharge temperature sensor configured to measure a temperature of refrigerant discharged from the compressor; a controller configured to control an opening degree of the first flow control device or the second flow control device on a basis of a discharge temperature measured by the discharge temperature sensor; an auxiliary heat exchanger outlet temperature sensor configured to measure a temperature of fluid subjected to heat exchange at the auxiliary heat exchanger; and an outside air temperature sensor configured to measure a temperature of air to be subjected to heat exchange at the heat source side heat exchanger, the controller being configured to increase the opening degree of the first flow control device or the second flow control device when a temperature measured by the discharge temperature sensor is higher than a discharge temperature target value that is a target temperature of refrigerant discharged from the compressor, and to decrease the opening degree of the first flow control device or the second flow control device when the temperature measured by the discharge temperature sensor is lower than the discharge temperature target value, in the cooling operation, the controller being configured to determine whether to control the first flow control device on a basis of a difference between a temperature measured by the auxiliary heat exchanger outlet temperature sensor and a temperature measured by the outside air temperature sensor.
