SYSTEM AND METHOD FOR REGULATING A HEATING HUMIDIFIER
First Claim
1. A method for supplying a regulated degree of humidification (m) of air, the method comprising:
- providing a water reservoir configured such that air contacting a surface of water in the reservoir is charged with humidity;
providing a heating device for heating the water in the reservoir by circulating an electric current;
measuring an average intensity (Iav) of the current passing through the heating device; and
controlling the average intensity (Iav) relative to a reference value (Iavc) to obtain a degree of humidification (m) of the air that is independent of an ambient temperature (Ta).

Abstract
A method for supplying a mask through which air flows with a regulated degree of humidification (m) is provided. The method may include: providing a water reservoir configured such that the air circulates in contact with the surface of water within the reservoir is charged with humidity; providing a heating device for heating the water in the reservoir by circulating an electric current; measuring an average intensity (Iav) of the current passing through the heating device; and controlling the average intensity (Iav) relative to a reference value (Iavc) to obtain a degree of humidification (m) of the air that is independent of the ambient temperature (Ta). An apparatus for regulating the degree of humidification of air flow, as well as a heating humidifier including such a regulation device, are also provided.
