In-vehicle temperature control system

An in-vehicle temperature control system which is provided with a vehicle, comprising:

• a refrigeration circuit having:
• a first heat exchanger for absorbing heat from a first heat medium to a refrigerant to evaporate the refrigerant;
• and a second heat exchanger for releasing heat from the refrigerant to an outside to condense the refrigerant and being able to use the released heat for heating an interior of the vehicle, wherein the refrigeration circuit is configured to realize a refrigeration cycle by circulating the refrigerant through them;
• a first thermal circuit having:
• the first heat exchanger;
• and an external heat exchanger for absorbing heat from an outside to the first heat medium, wherein the first thermal circuit is configured to circulate the first heat medium through them;
• and
• a controller capable of changing a heat absorption amount of the refrigerant at the first heat exchanger and for controlling a device associated with the refrigeration circuit or the first thermal circuit, wherein
• the controller is configured to control the device in a direction where a change in the heat absorption amount of the refrigerant at the first heat exchanger in accordance with a change in a temperature of the first heat medium is reduced, if the temperature of the first heat medium flowing through the first heat exchanger changes by a reference value or more, or if the temperature of the first heat medium flowing through the first heat exchanger is predicted to change by a reference value or more, during heating of the interior of the vehicle.
