Refrigerant circuit and air conditioner

In the refrigerant circuit of this air conditioner 10, an upper heat-source-side heat exchanger 2a with a high heat load and a lower heat-source-side heat exchanger 2b with a low heat load are connected in parallel between a throttle device 15 and the intake side of a compressor 4. The refrigerant circuit of the air conditioner 10 is equipped with a branch circuit 9 which distributes a refrigerant to the upper heat-source-side heat exchanger 2a and the lower heat-source-side heat exchanger 2b. The branch circuit 9 is configured so as to supply, to the upper heat-source-side heat exchanger 2a, the refrigerant with a dryness lower than the refrigerant supplied to the lower heat-source-side heat exchanger 2b.
