Abstract

In a climate control system for a vehicle having at least one refrigerant circuit, at least one temperature control circuit for controlling the temperature of a vehicle interior, and at least one vehicle component, in particular of an electric vehicle or hybrid vehicle, at least one device for absorbing heat from the temperature control circuit and at least one device for releasing heat to the temperature control circuit are provided. In a method for controlling the temperature of vehicle components using at least one refrigerant circuit and at least one temperature control circuit, heat is absorbed from the temperature control circuit into the refrigerant circuit on the low-pressure side of the refrigerant circuit, and heat is released to the temperature control circuit by the refrigerant circuit on the high-pressure side of the refrigerant circuit.
