Thermal management system

A thermal management system comprising:

• a refrigerant circuit configured to circulate refrigerant and including a compressor, a high-temperature-side heat exchanger, a decompression device, and a low-temperature-side heat exchanger;
• a high-temperature-side heat medium circuit including a heater core that heats air supplied into a vehicle cabin and configured to circulate a heat medium capable of exchanging heat with the refrigerant via the high-temperature-side heat exchanger;
• a low-temperature-side heat medium circuit including a cooler core that cools air supplied into the vehicle cabin and configured to circulate a heat medium capable of exchanging heat with the refrigerant via the low-temperature-side heat exchanger;
• a heat absorbing target heat exchange circuit including a heat exchanger for a heat absorbing target and configured to circulate a heat medium;
• and
• a channel switching device configured to switch the low-temperature-side heat medium circuit and the heat absorbing target heat exchange circuit between a connection state and an independent state, wherein
• the low-temperature-side heat medium circuit includes a flow divider for a heat medium, which is disposed downstream of the cooler core, and
• when a dehumidification heating operation is performed in the vehicle cabin,
• in the high-temperature-side heat medium circuit, a heat medium circulates between the high-temperature-side heat exchanger and the heater core,
• the channel switching device connects the low-temperature-side heat medium circuit and the heat absorbing target heat exchange circuit, and
• the flow divider is capable of dividing a heat medium having flowed through the cooler core into a first channel through which the heat medium having flowed through the cooler core flows to the low-temperature-side heat exchanger without passing through the heat exchanger for the heat absorbing target and a second channel through which the heat medium having flowed through the cooler core flows to the low-temperature-side heat exchanger via the heat exchanger for the heat absorbing target.
