Abstract
A temperature adjustment circuit includes a first temperature adjustment circuit and a second temperature adjustment circuit in which a switching part that is configured to switch between a circulation state where a heat-transfer medium is circulated through a connection circuit in which the first temperature adjustment circuit and the second temperature adjustment circuit are connected to each other and a non-circulation state where the heat-transfer medium is not circulated through the connection circuit.
Claims15
A temperature adjustment circuit comprising:
- a first temperature adjustment circuit that includes:
- a first pump that is configured to supply a heat-transfer medium to a first cooling target and
- a first heat exchanging part that transfers heat between the heat-transfer medium and an air-conditioning refrigerant;
- a second temperature adjustment circuit that includes:
- a second pump that is configured to supply the heat-transfer medium to a second cooling target and
- a second heat exchanging part that transfers heat between the heat-transfer medium and outside air;
- a first connection path that connects a first connection portion of the first temperature adjustment circuit and a first connection portion of the second temperature adjustment circuit;
- a second connection path that connects a second connection portion of the first temperature adjustment circuit and a second connection portion of the second temperature adjustment circuit;
- and
- a switching part that is configured to switch between
- a circulation state where the heat-transfer medium is circulated through a connection circuit in which the first temperature adjustment circuit and the second temperature adjustment circuit are connected to each other and
- a non-circulation state where the heat-transfer medium is not circulated through the connection circuit,
- wherein the first heat exchanging part is disposed between the second connection portion of the first temperature adjustment circuit and the first connection portion of the first temperature adjustment circuit in a flow direction of the heat-transfer medium in the first temperature adjustment circuit in the non-circulation state, and
- wherein the switching part includes:
- a first shut-off valve that is provided between the second connection portion of the first temperature adjustment circuit and the first heat exchanging part in a flow direction of the heat-transfer medium in the first temperature adjustment circuit in the non-circulation state and
- a second shut-off valve that is provided between the first connection portion of the second temperature adjustment circuit and the first connection portion of the first temperature adjustment circuit in a flow direction of the heat-transfer medium in the connection circuit in the circulation state.
