Title:
METHOD AND DEVICE FOR SAVING HEAT ENERGY AND WATER IN A SANITARY FACILITY
Document Type and Number:
WIPO Patent Application WO/2017/216432
Kind Code:
A3
Abstract:
A device for a sanitary facility, intended for rapidly delivering Domestic Hot Water (DHW) to the supply points without wasting energy. The device according to the invention transfers the DHW rapidly from the source to the user as soon as there is a need for it. The method, which prevents any recirculation, makes it possible, in particular, to save the large amount of energy that is systematically wasted each time the DHW is distributed between its source and the supply points. The device essentially consists of a motorised, relatively powerful pump (2) which channels the DHW from the source (1) and injects it into a pipe with a very small cross-section (3) that conveys the entire flow rate required by the user at a high velocity to the supply point (41). An adapted sensor (5) controls the switching on and off of the motor pump (2) upon each use and controls its flow rate on the basis of the requirements. A single device can be used for supplying multiple supply points. It can be fitted to all new or existing facilities.
