Method from the thermal conditioning of an internal combustion engine and/or of a passenger compartment of a vehicle, and vehicle

Abstract

Thermal conditioning of a combustion engine of a vehicle is achieved by means of a fluid circuit or a sub-circuit of the fluid circuit and/or the air flowing into a passenger compartment of the vehicle by means of a heat pump circuit. In at least one operational state of the vehicle, heat is transferred from the fluid circuit or the sub-circuit of the fluid circuit to the heat pump circuit.
