Ultrasound humidifiers

Ultrasound humidifiers feature a small water storage tank and piezoelectric transducers installed at the bottom of the tank.
The surface of the transducer oscillates at a very high speed (1.65 million times per second), so as to prevent the water from moving (the water cannot keep up with the oscillations of the transducer) due to its mass inertia. As a consequence, a column of water is generated above the transducers.
During the negative amplitude of the transducer, an instant vacuum is produced because the water cannot follow the very fast transducer movements. The cavity created allows the production of bubbles, which are pushed to the edge of the water column during the positive amplitude phase, where they collide. During this process, very fine particles of water are atomized on the edge of the column of water.
Due to the sound waves, cross waves are produced directly underneath the surface of the water, in the center of which very small water droplets are separated thus generating a mist, which is absorbed immediately by the air stream.
Ultrasound technology applied to air humidifiers is an efficient and versatile solution:
  • it is efficient because ultrasound humidifiers guarantee high energy saving (over 90%) if compared to common steam generators;
  • it is versatile thanks to the dimensions of the droplets produced (average diameter of 0.005 mm). This fundamental feature guarantees rapid absorption of the atomised water in the surrounding area, thus preventing possible condensation.
humiSonic is the new ultrasound humidifier developed by CAREL. It has been developed to control and maintain the desired level of humidity for a specific environment constant. humiSonic, installed on fan coils, is the ideal solution for coupling accurate control of ambient humidity with common temperature control (guaranteed by the fan coils). The combination and accurate management of these two fundamental features of the air assure that comfortable conditions in the home or commercial environment can be reached and maintained.
The forced ducting system, installed between the coil and the air outlet, easily manages to evenly distribute the mist in the fan coil outlet duct.
By supplying humiSonic with a humidity probe and flow sensors (TAM), a complete solution is obtained that can operate completely independently!
