LIQUID DISTRIBUTION SYSTEM AND METHOD FOR MAINTAINING ITS TEMPERATURE BY INDUCTION

摘要

The invention concerns a liquid distribution system, in particular of domestic hot water supply, comprising a generator (3), connected to a main collecting pipe (5) whereon are mounted in parallel several distribution pipes (6), not comprising return pipes between the distribution pipes and said generator, each of the distribution pipes being closed at its downstream end relative to the generator, not comprising means for circulating the liquid permanently in the system, and such that each pipe includes over its entire length at least one continuous conductive layer made of ohmic conductor material of the electric current, each pipe comprising at least one conduit (40; 65), the conduit consisting of a metal core (43; 67) interposed between an inner layer (45; 71) and an outer layer (44; 70) of an electric insulation, each pipe being equipped with at least one means for temperature maintenance by induction (20) including a linking element made of conductor material (28) of the electric current connecting two portions (A, B) of said continuous conductive layer so as to form a closed conductor loop (ABA) and a device for generating a variable magnetic flux (30) throughout said closed loop.
