1. A heat management system comprising:
a high-temperature heat medium circuit connecting a heat medium and refrigerant heat exchanger and a heater core to circulate a heat medium, the heat medium and refrigerant heat exchanger being configured to adjust a temperature of a heat medium by heat exchange with a refrigerant circulating in a refrigeration cycle, and the heater core being configured to radiate heat of the heat medium to ventilation air to be blown to a space to be air conditioned;
a low-temperature heat medium circuit connecting a radiator and a heat generation equipment to circulate the heat medium, the radiator being configured to radiate heat of the heat medium to outside air, and the heat generation equipment being configured to generate heat in accordance with operation and to have a temperature adjusted by the heat of the heat medium;
a circuit connection part connecting the high-temperature heat medium circuit and the low-temperature heat medium circuit, to flow in and out the heat medium in the high-temperature heat medium circuit and the low-temperature heat medium circuit; and
a circuit switching part configured to switch the flow of the heat medium flowing in the high-temperature heat medium circuit, the low-temperature heat medium circuit and the circuit connection part, wherein
the circuit switching part is configured to switch between
an operation mode in which the heat medium heated by the heat medium and refrigerant heat exchanger is circulated to pass through the heater core, and
an operation mode in which the heat medium heated by the heat generation equipment and the heat medium and refrigerant heat exchanger is circulated to pass through the heater core, and

in the operation mode in which the heat medium heated by the heat generation equipment and the heat medium and refrigerant heat exchanger is circulated to pass through the heater core, the circuit switching part is configured to switch an operation mode in which the heat medium is circulated in a circulation path via the heat medium and refrigerant heat exchanger and the heater core, and the heat medium is circulated in a heat medium circulation path via the heat generation equipment and the radiator independently of a heat medium circulation path via the heat medium and refrigerant heat exchanger and the heater core, when the temperature of the heat medium is higher than a predetermined reference temperature.
