To improve efficiency in an air conditioning system heating a room by utilizing hot heat generated by a so-called supercritical cycle.
This air conditioning system 10 is provided with: a refrigerant circuit 21 performing a refrigerating cycle; and a heat transporting circuit 30 for circulating heat medium water. In the heat transporting circuit 30, an air heat exchanger 76 is disposed downstream of a heat exchanger 75 for heating. The heat exchanger 75 for heating is composed of a floor heating panel and a radiation panel. The air heat exchanger 76 exchanges heat between the indoor air supplied by an indoor fan 77 and the heat medium water. The heat medium water heated in a secondary side passage 23b of the heat source side heat exchanger 23 radiates heat in the heat exchanger 75 for heating, further radiates heat in the air heat exchanger 76, and then returns to the heat source side heat exchanger 23. In the refrigerant circuit 21, the refrigerant discharged from a compressor 22 flows into a primary side passage 23a of the heat source side heat exchanger 23, and radiates heat to the heat medium water flowing in a secondary side passage 23b.
