SELF-SUPPLIED MOUTH WITH FLOW REGULATION AND METHOD FOR REGULATING AN ASSOCIATED VMC INSTALLATION

摘要

The invention consists of a ventilation opening for a ventilation installation, which comprises a flow sensor (12) and means (13, 15) for autonomously controlling the flow of air passing through it to a given flow set point. . The ventilation mouth further comprises an autonomous energy supply (14) which makes it possible to supply all of the electrical and electronic elements necessary for its operation. The flow rate setpoint is either a given fixed value or a function value determined from a law of variation of an external parameter supplied by one or more sensors (16) carried by the mouth or by elements external to the mouth. The invention also consists of a ventilation installation using such ventilation openings (10) and a method of regulating the operation of such an installation, a process which exploits the characteristics of the ventilation openings according to the invention.
