Abstract
A temperature adjustment circuit includes a first temperature adjustment circuit and a second temperature adjustment circuit in which a control device 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.
Claims9
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;
- a three-way valve that is provided in the first connection portion of the second temperature adjustment circuit and is configured to switch between supply of the heat-transfer medium to the second connection portion of the second temperature adjustment circuit and supply of the heat-transfer medium to the first connection path;
- a shut-off valve that is provided between the first connection portion of the first temperature adjustment circuit and the second connection portion of the first temperature adjustment circuit;
- and
- a control device that is configured to control the three-way valve and the shut-off valve,
- wherein the control device is configured to switch between
- a circulation state where the shut-off valve is set to a valve-closed state and the three-way valve is controlled to supply the heat-transfer medium to the first connection path so that 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 shut-off valve is set to a valve-open state and the three-way valve is controlled to supply the heat-transfer medium to the second connection portion of the second temperature adjustment circuit so that the heat-transfer medium is not circulated through the connection circuit.
