Thermal management system

A thermal management system comprising:

• a refrigeration cycle equipment including
• a high-temperature-side water-refrigerant heat exchanger configured to perform heat exchange between high-pressure refrigerant and heating medium and
• a low-temperature-side water-refrigerant heat exchanger configured to perform heat exchange between low-pressure refrigerant and the heating medium;
• and
• a heating medium circuit configured to circulate the heating medium, wherein
• the heating medium circuit includes
• a high-temperature-side circuit connecting with a heating medium channel of the high-temperature-side water-refrigerant heat exchanger,
• a low-temperature-side circuit connecting with a heating medium channel of the low-temperature-side water-refrigerant heat exchanger, and
• a heat transfer portion configured to transfer heat between the heating medium, which flows through the high-temperature-side circuit, and the heating medium, which flows through the low-temperature-side circuit,
• the low-temperature-side circuit includes
• a first heat exchanger configured to perform heat exchange between a first temperature adjustment target and the heating medium,
• a second heat exchanger configured to perform heat exchange between a second temperature adjustment target and the heating medium,
• a heating medium bypass channel configured to
• cause the heating medium, which flows out of one of the first heat exchanger and the second heat exchanger, to bypass the low-temperature-side water-refrigerant heat exchanger and
• return the heating medium toward a heating medium inlet of one of the first heat exchanger and the second heat exchanger, and
• a low-temperature-side circuit switching valve configured to switch a circuit configuration of the low-temperature-side circuit,
• when the first temperature adjustment target is heated,
• the heat transfer portion is configured to transfer heat of the heating medium, which is heated by the high-temperature-side water-refrigerant heat exchanger, to the heating medium, which flows into the first heat exchanger,
• the low-temperature-side circuit switching valve is configured to switch a circuit configuration of the low-temperature-side circuit to a circuit configuration that returns the heating medium, which flows out of the first heat exchanger, toward the heating medium inlet of the first heat exchanger via the heating medium bypass channel, and
• the low-temperature-side circuit switching valve is configured to concurrently
• connect an outlet of a channel of the first heat exchanger directly with an inlet of the heating medium bypass channel and
• connect an outlet of a channel of the second heat exchanger directly with an inlet of the heating medium channel of the low-temperature-side water-refrigerant heat exchanger.
