摘要

The system includes a first cooling circuit (10) with a first compressor (12), a condenser (14), an expansion member (16) and a first vaporizer (18), and a processing unit having a fuel cell (20) to drive the compressor (12) with electric energy. At least a second vaporizer (22) is provided so as to provide a second cooling circuit (24) which is connected to the first cooling circuit.
