Temperature-Control Device for a Motor Vehicle, in Particular for a Car, and Motor Vehicle Having Such a Temperature-Control Device

A temperature-control device for a motor vehicle, comprising:

• a temperature-control circuit through which a temperature-control medium flows, and in which an ambient air cooler, a drive machine for driving the motor vehicle, an electrical energy storage device, a first heat exchanger that is also arranged in a coolant circuit through which a coolant flows and via which heat is exchangeable between the coolant and the temperature-control medium, and a second heat exchanger that is also arranged in the coolant circuit and via which heat is exchangeable between the coolant and the temperature-control medium are arranged;
• a temperature detection device configured to detect a first temperature of the temperature-control medium upstream of the ambient air cooler, a second temperature of the temperature-control medium upstream of the drive machine, a third temperature of the temperature-control medium upstream of the energy storage device, an ambient temperature as a fourth temperature of the surroundings of the motor vehicle, and a fifth temperature of the electrical energy storage device;
• and
• an electronic computing device configured to operate the temperature-control device:
• in a first heat pump operating mode when the first temperature is greater than a predetermined first threshold value and the second temperature is greater than a predetermined second threshold value, wherein in the first heat pump operating mode, the ambient air cooler, the drive machine, and the first heat exchanger are connected in series and a flow of the temperature-control medium through the energy storage device and the second heat exchanger does not take place;
• and
• in a second heat pump operating mode when the second temperature is greater than the first threshold value and less than a third threshold value, which is greater than the first threshold value, and greater than the ambient temperature, wherein in the second heat pump operating mode, the drive machine and the first heat exchanger are connected in series and a flow of the temperature-control medium through the ambient air cooler, the energy storage device, and the second heat exchanger does not take place.
