Interior heating and cooling system for motor vehicle, has by-pass line that bridges the segment of heat transfer circuit which runs through an internal combustion engine to form an isolated circuit in a bridged operating state

摘要

A heat transfer circuit (1) has a segment (6) routed via a fuel cell (4) to transfer exhaust heat of the fuel cell to the circuit. A by-pass line (5) bridges the segment, which runs through an internal combustion engine, to form an isolated circuit in a bridged operating state. An Independent claim is also included for a climate control unit.
