Temperature regulation and ventilation device for passenger carrying vehicles

摘要

An arrangement for controlling the interior temperature of a passenger transit vehicle 10 of the kind driven by a liquid-cooled engine and for ventilating the interior of the vehicle, comprises a primary closed system of conduits positioned near the vehicle floor and which conducts hot engine coolant from the engine to the passenger space and the driver's space of the vehicle. Arranged above the vehicle windows is at least one further closed conduit system which is embraced along at least the greater part of its length by ducting 40. The ducting communicates with fresh-air intakes 14 and is constructed to direct the incoming air into contact with the hot water conduits and to supply this air via openings 37 into the passenger space and/or the driver's space of the vehicle. In hot weather (see left hand side of Figure 2) cold liquid is supplied to the conduits in the ducting 40 and the cooled air is also supplied to the vehicle through outlets in further ducting 41.
