Abstract

A humidifier (52) of a heated pass-over type comprises a heater plate (70), water reservoir (62), sensors (86), and a controller (88). The sensors generate signals for conveying humidifier operating status and ambient conditions. The controller is configured to: (i) predict a water mass within the water reservoir based on predetermined heat and water mass transfer functions of a given humidifier design, the sensor signals, and heater plate power; (ii) determine a length of time to evaporate all water of the predicted water mass; and (iii)(a) output a warning signal in response to predicted water mass being insufficient for a remainder of the treatment duration, or (iii)(b) adapt a power setting to change the evaporation rate of the current predicted water mass to ensure that it is sufficient to last for a remainder of the treatment duration and prevent the water reservoir from running dry.
