Claim Text:
1. A method for operating a circuit, having a heat accumulator, having a coolant circuit, having a heat accumulator in a line of the circuit and having at least one valve and one pump, wherein, when the at least one valve is open, a coolant from the cooling circuit charges the heat accumulator by way of the at least one pump, or coolant discharges from the heat accumulator into the coolant circuit, wherein the charging or discharging of the heat accumulator takes place in an open-loop-controlled or closed-loop-controlled manner as a function of a temperature of the coolant in the circuit or a temperature of the coolant in the heat accumulator or a temperature difference therebetween, wherein charging of the heat accumulator takes place when the temperature of the coolant in the cooling circuit exceeds the temperature of the coolant in the heat accumulator by a first predefinable value or the temperature of the coolant has reached a first predefinable value, wherein discharging of the heat accumulator into the cooling circuit takes place when the temperature of the coolant in the heat accumulator exceeds the temperature of the coolant in the cooling circuit by a first predefinable value, wherein the temperature of the first predefinable value increases from one charging process to the next.
