Abstract

A control system method is disclosed for air-conditioning a vehicle by a heat pump system, wherein one of multiple operating modes is automatically set, depending on the air-conditioning requirement. The passenger space is cooled by an air-conditioning evaporator and/or is heated by a heating heat exchanger. The heating heat exchanger is arranged in a heating branch of a coolant circuit and is provided with heat via a heat pump. If cooling is required, the heating branch is opened and the heating pump is deactivated. If heating is required, the heating branch is closed and heat is fed to the heating heat exchanger via the heat pump. In order to remove heat from the heating branch, same is opened and a low-temperature cooler, the condenser and the heating heat exchanger are operated connected in series.
