1. A system for a vehicle, comprising:
a vehicle cooling circuit for cooling a temperature-increasing device via a coolant conducted in a coolant circuit, wherein the coolant circuit includes a coolant line, at least one chiller, a coolant pump, and at least one heat exchanger configured as an evaporator coupling the coolant circuit to a cooling medium circuit including a cooling medium line, at least one compressor, at least one condenser, and at least one relief valve, wherein the at least one chiller is arranged downstream of the at least one heat exchanger in a direction of flow of the coolant in the coolant circuit, wherein a heat exchanger bypass valve is arranged in the coolant line such that the coolant can be fully or partially conducted past the heat exchanger, and wherein at least one chiller bypass valve is arranged in the coolant line such that the coolant is conducted fully or partially past the at least one chiller; and
a controller including executable instructions stored in non-transitory memory to:
determine an environmental temperature;
determine a required temperature at a coolant inlet of the temperature-increasing device; and
if the environmental temperature is higher than the required temperature, open the at least one chiller bypass valve and close the heat exchanger bypass valve.
