ELECTRIC HEATING SYSTEM FOR A FLUID LINE SYSTEM

摘要

A heating system for a fluid pipe system in which at least one electric heating element (RL) is assigned to at least one fluid line, said heating element, in order to apply a predetermined heating output to the fluid line, being provided with an electric operating voltage (UB) that is reduced compared to the supply voltage (U).

1. A heating system for a fluid-line system, the heating system comprising:
at least one electrical heating element (RL) assigned to at least one fluid line, the at least one heating line being supplied with an electrical operating voltage (UB) in order to apply a predetermined heating power to the fluid line, wherein the at least one heating element (RL) is synchronously controlled in a pulse-width-modulated manner using an electronic control element sets or regulates its heating power with a specific or variable duty cycle, the at least one heating element (RL) assigned to the at least one fluid line being electrically connected in series with at least one further heating element (RV1/RV2), wherein the control element controls at least one subset of the available heating elements (RL, RV1, RV2) individually for individual setting or regulating of their heating power.
