Provided is a technology to prevent a lack of heating capacity. The air conditioning system (2) of the present invention comprises: a compressor (12) for compressing a refrigerant; indoor terminals (14a, 14b) for radiating heat of the compressed refrigerant; expanding valves (18a, 18b) for expanding the refrigerant; an outdoor air heat exchanger (20) for absorbing heat from the atmosphere; a first circulation path (28) for circulating the refrigerant from the compressor (12), the indoor terminals (14a, 14b), the expanding valves (18a, 18b), and the outdoor air heat exchanger (20) in order; a second circulation path (50) for circulating a heating medium; a heat exchanger (24) for letting heat exchange occur between the refrigerant in the first circulation path (28) and the heating medium in the second circulation path (50); and a burner (52) for heating the heating medium in the second circulation path (50) by using the heat generated by combustion of the fuel. |
