Effective application of adiabatic humidification


10 July 2024

CAREL has published a new white paper looking at energy efficiency and cost reduction in adiabatic humidification.

Energy Saving in Adiabatic Humidification: Principles, Applications, and Benefits explores the potential of adiabatic humidification, a process that adds moisture to the air without the need for external heat sources.

The document illustrates how adiabatic systems not only optimise indoor air quality conditions but also promote energy savings, reduce operational costs and meet the sustainability criteria required by current regulations.

The white paper first introduces the fundamentals of adiabatic humidification, explaining what it is and how it works. It then analyses various types of adiabatic humidifiers, including pressurised water humidifiers, ultrasonic humidifiers, compressed air humidifiers, and centrifugal humidifiers, comparing them with traditional isothermal humidifiers. A particular focus is dedicated to comparing the energy and water use of these systems, highlighting the significant benefits of adiabatic humidification.

The document also examines specific applications of this technology in data centres, where efficient humidity control can lead to substantial energy consumption reductions. Through practical examples, it shows total utility cost savings, total energy use, cooling energy savings, and water use. Additionally, the document presents the reduced need for humidification and heating energy, demonstrating how adiabatic humidification can contribute to more efficient and sustainable operations.

"In our ongoing quest for innovative and sustainable solutions, our decades-long expertise in adiabatic humidification remains a constant reference point," said Stefano Ruzzon, Group Head of Sales and Marketing, Humidification Division. "This white paper provides a comprehensive guide to understanding how this technology can be effectively applied across various sectors, enhancing the efficiency of air quality improvement systems and contributing to a more sustainable future."
