Heating device for passenger accommodations in public commuter vehicles

摘要

In this device, an insulating chamber (1) with heating elements (2) is arranged as a heat accumulator which can be flowed through, it being possible to supply the heating elements with electricity from the traction motor (7) in a generator circuit via a control element (6, 10) which can be operated as a function of the brakes. In order to heat the passenger compartment, a controllable hot airstream (11) from the heat accumulator (1, 2) and an external airstream (3) are adjusted by means of a mixing chamber (17) in accordance with the prevailing conditions and fed via a blower (14).
