Heat management system

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;
• an equipment heat exchange part connected to allow inflow and outflow of the heat medium and configured to exchange heat between the heat medium and a target equipment to be subjected to temperature adjustment;
• 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
• the circuit switching part is configured to switch an operation mode in which the heat medium having passed through the heat medium and refrigerant heat exchanger is circulated to pass through the equipment heat exchange part, and a heat medium circulation pass via the heater core is made independent of a heat medium circulation path including the heat medium and refrigerant heat exchanger and the equipment heat exchange part.
