5. Agenda  Isothermal vs adiabatic humidification  Ultrasonic humidification  humiSonic direct: features  Applications

6. • Dry bulb temperature is the one we normally perceive. It is a measure of  sensible heat. • Relative humidity is the value that  indicates how far the air is from  saturation. When air is 100% saturated  condensate starts forming. • The capacity of air to contain humidity increases with  temperature. Steam vs adiabatic technologies

7. • Isothermal humidification is achieved by introducing steam into the air • Energy for the water to steam change of state (≈700W/l) is provided externally. Enthalpy increases • Air temperature does not change (hence isothermal) Steam vs adiabatic technologies STEAM HUMIDIFICATION

8. • Adiabatic humidification is achieved by  spraying fine water droplets • Water spontaneously evaporates • Energy for the change of state is provided by air. The total amount of energy does not change (hence adiabatic) • Sensible heat is converted into latent heat Air is cooled Steam vs adiabatic technologies ADIABATIC HUMIDIFICATION

13. STAND‐ALONE UNIT humiSonic needs just the power, RO  water and drain connections:  control/electrical panel is not  needed  built‐in humidity probe plug & play! Features

14. CAPACITY (kg/h) 2 - 4 - 6 - 8 - UU02 UU04 UU06 UU08 Features

15. POWER CONSUMPTION (W/kg) humiSonic needs less than 80 watt per kg of nebulized water, about 10% compared to steam technology 0 100 200 300 400 500 600 700 800 Isothermal humiSonic Features

16. ENDURANCE • power 0,5 kg/h • lifetime 10.000 hr with RO water the transducer’s driver has been  developed by Carel Features

17. hours Features ENDURANCE

18. PRECISION humiSonic stand‐alone  guarantees a ±5% accuracy  around the set point. Accuracy can be improved: • Active humidity probe (optional) more accurate than the embedded one • Proportional signal 0‐10V / 4‐20mA integration with the bms -5% +5% SP rh capacity Features

19. PRECISION SP rh capacity on requested capacity Features

20. HYGIENE hygiene on adiabatic solutions is a must for CAREL  automatic washing cycles management  automatic tank drain if shut down  each component in touch with                                             water is stainless steel made   humiSonic uses fresh RO water with the additional safety of the UV lamp Features

21. MASTER/SLAVE for extra capacity demand or homogeneous humidity  distribution a master unit can drive up to three humiSonic,  for a total system capacity of 32 kg/h. Each slave unit matches the master status. T‐Lan Features
