Data Room Humidification

ASHRAE Sets the Standards for the Recommended Data Room Operating Environment -Temperature -Humidity Reason? -To Reduce the Risk of ESD (Electrostatic Discharge) -ESD can damage electrical equipment -ESD can cause errors in operation & readings Sets the Standards for the Recommended Data Room Operating Environment -Temperature -Humidity Reason? -To Reduce the Risk of ESD (Electrostatic Discharge) -ESD can damage electrical equipment -ESD can cause errors in operation & readings

ASHRAE 2004 Recommended Data Room Operating Environment -Temperature = Low End at 68º F (20º C) High End at 77º F (25º C) -Humidity = Low End at 40% RH High End at 55% RH 2004 Recommended Data Room Operating Environment -Temperature = Low End at 68º F (20º C) High End at 77º F (25º C) -Humidity = Low End at 40% RH High End at 55% RH

Why Use Dew Point for Moisture Control? Studies show ESD is function of: -Absolute Humidity in Air, Not Relative Humidity of Air Studies show ESD is function of: -Absolute Humidity in Air, Not Relative Humidity of Air

Result ? ENERGY SAVINGS! Data Rooms can operate at: - Higher Temperatures - Lower RH Levels This Encourages Economizer Cooling ENERGY SAVINGS! Data Rooms can operate at: - Higher Temperatures - Lower RH Levels This Encourages Economizer Cooling

How To Humidify Data Centers ? 1. Central Humidification -AHU -Ductwork 2. In-Room Humidification -In-CRAC -Wall Mount -Free-Standing 1. Central Humidification -AHU -Ductwork 2. In-Room Humidification -In-CRAC -Wall Mount -Free-Standing

Problems with Central Humidifiers: 1.Economizer Means Outside Air -Cold Air -Wetting Risk -Control Issues -Location of Humidifier: -Harder to Service -Difficult to Monitor 2.Direct Injection Steam- chemicals in air from boiler (needs heat exchangeradds cost) 3. If Humidifier Must be Outside Data Room, Corridor/Gallery is Preferable 1.Economizer Means Outside Air -Cold Air -Wetting Risk -Control Issues -Location of Humidifier: -Harder to Service -Difficult to Monitor 2.Direct Injection Steam- chemicals in air from boiler (needs heat exchangeradds cost) 3.
