<P>PROBLEM TO BE SOLVED: To provide a liquid circulating system for a vehicle in which comfortability at start of cooling/heating operation is improved, and energy required for cooling and heating is kept low to improve energy saving performance. <P>SOLUTION: The system includes a refrigerant circuit 10 with which a compressor 1, a refrigerant water heat exchanger 2, an expansion valve 3 and a refrigerant air heat exchanger 4 are connected, and a water circuit 20 having a pump 21 circulating water heat-exchanged by the refrigerant water heat exchanger 2, a first heat exchanger 22 connected in series with the refrigerant water heat exchanger 2, and a second heat exchanger 23 and/or a third heat exchanger 24 respectively connected in parallel in the downstream side of the first heat exchanger 22. The first heat exchanger 22 transfers heat through air from a blower 28, the second heat exchanger 23 is installed on the surface of components constituting a vehicle interior other than a seat and transfers heat by radiation, and the third heat exchanger 24 is installed inside the seat and transfers heat by conduction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
