  9. The Science Behind Humidity • 1075 BTU/lb for water phase change (liquid to gas) • Isothermal (steam) humidifiers use electricity or gas • Adiabatic (evaporative) humidifiers draw energy from air Liquid Water Water Vapor(“Humidity”) ~1075 BTU/lb

  10. Adiabatic and the Psychometric Chart

  11. Temperature Drop Example: System CFM = 20,000 cfm Humidity load = 200 lbs/hr *Heat is removed at a rate of roughly 1075BTU’s/lb of water evaporated Formula: T = BTU CFM x 1.10 (Constant) T = 200 x 1075 BTU 20,000 CFM x 1.10  T = 9.8°F Cooling and humidity go hand in hand!

  12. Adiabatic: The “Sensible” Solution • Best Scenarios • Constant cooling load • Waste heat is available • Summer cooling / humidity • Regional applications

  13. Applications

  14. Applications: LEED Projects • Energy conscious (low kW) • Consider summer cooling • Humidity control • Synergies: EAp2, EAc1 EQc7, ID

  15. Nortec Adiabatic Systems HP HVAC MH Series AFE Nozzles
