Abstract
In a refrigerant circuit of an air conditioning device, an upper heat source side heat exchanger having a large heat load and a lower heat source side heat exchanger having a small heat load are connected in parallel between an expansion device and a suction side of a compressor. Additionally, the refrigerant circuit of the air conditioning device is provided with a branch circuit configured to distribute refrigerant to each of the upper heat source side heat exchanger and the lower heat source side heat exchanger, and the branch circuit is configured to supply the upper heat source side heat exchanger with refrigerant of lower quality than that of the refrigerant supplied to the lower heat source side heat exchanger.
