Data Room HumidificationData Room Humidification

ASHRAEASHRAESets 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

Studies show ESD is function of:

-“Absolute Humidity” in Air,

Not “Relative Humidity” of Air

ENERGY SAVINGS!

Data Rooms can operate at:

- Higher Temperatures - Lower RH Levels

This Encourages Economizer Cooling

Problems with Central Humidifiers:

Problems with Central Humidifiers:

1. Economizer Means Outside Air -Cold Air -Wetting Risk -Control Issues -Location of Humidifier: -Harder to Service -Difficult to Monitor2. Direct Injection Steam- chemicals in air from

boiler (needs heat exchanger—adds cost)3. If Humidifier Must be Outside Data Room,

Corridor/Gallery is Preferable

Benefits of In-Room HumidificationBenefits of In-Room Humidification1. Direct Room Introduction of Moisture a) Higher Output Capacity

2. Better Control a) Sense Room Moisture without

Concern of High-Limit Saturation

b) More Accurate. Particularly with Individual Sensors

3. Easier to Service

4. Safety Overflow Control by Sensor and Drain Piping
