Abstract (en)
[origin: WO9941097A1] The present invention relates to an arrangement in a closed, pressurised, fluid heating system (1) for vehicles with an onboard heat source (2). A feed-line (3) and a return-line (4) are connected to the onboard heat source (2). At least two climate-circuits (5, 6) with heat-exchanger means are arranged for heating of different parts of the vehicle interior. A bypass-line and valve means are arranged to selectively permit fluid flow between the feed-line (3) and the return-line (4). An inlet side of each respective climate-circuit (5, 6) is connected to a first output of a respective three-way valve (7, 8), whose input is connected to the feed-line (3). An inlet side of a respective bypass-line (10, 11) is connected to a second output of the same three-way valve. An outlet side of each climate-circuit (5, 6) and each bypass-line (10, 11) is connected to the return-line (4). Each respective three-way valve (7, 8) is arranged to selectively apportion the fluid flow between the respective climate-circuit (5, 6) and the respective bypass-line (10, 11) connected thereto.
