<P>PROBLEM TO BE SOLVED: To provide a thermal fluid supply system having high energy efficiency and supplying a thermal fluid at various temperature levels. <P>SOLUTION: The thermal fluid supply system includes a first device (10), heat exchange devices (41, 42, 43) and a second device (20). The first device (10) includes a heat pump (10) including a multistage compression part (12) having at least two stages. In the heat exchange devices (41, 42, 43), heat from first fluid is transferred to second fluid. The second device (20) outputs the second fluid which has received heat transferred from the first fluid. The thermal fluid supply system is further provided with a first mode in which heat from the first fluid compressed by the compression part (12) with respect to each stage is transferred to the second fluid; a second mode in which heat from the first fluid compressed continuously by at least the two stages of the compression part (12) is transferred to the second fluid; and a control device (70) for switching the first mode and the second mode. <P>COPYRIGHT: (C)2010,JPO&INPIT |
