PROBLEM TO BE SOLVED: To provide an air conditioning hot water supply system capable of improving comfortableness by providing changing between hot water supply, floor heating, and floor cooling, and preventing dew formation in a room and accumulation of cold air in a room lower part during floor cooling. SOLUTION: In a first circulation circuit 7, a hot water storage tank 1, a first circulating pump 8, a heat absorbing side heat exchanger 9, and a utilization side heat exchanger 10 are communicated with each other. A refrigerating cycle device 12 is provided with a main heat exchange part 13 carrying out heat exchange with the heat absorbing side heat exchanger, and heat pump system refrigerating cycle components are communicated with each other. In a floor cooling and heating device 18, a cold-hot water heat exchange part 19 carrying out heat exchange with the utilization side heat exchanger, a second circulating pump 20, and a cold-hot water circuit 21 embedded in a floor Y of the room R are communicated with each other. A desiccant unit 23 is provided with an adsorption rotor 26, and it supplies outside air after removing moisture contained in the outside air. A second circulation circuit 35 is comprised by communicating the hot water storage tank, a third circulating pump 36, a heating part 37 in the desiccant unit, and a hot water circuit 38 embedded in the floor of the room with each other.
