Use available resources to calculate load correctly

When specifying a humidification system to meet design conditions, expect a maximum humidification load of two to three pounds per hour for every 100 cfm of outside air introduced. A humidified building constantly loses moisture, primarily due to air changes. As a general rule, humidification load is driven by the amount of outside or makeup air entering a building or space, and calculated based on the difference between entering conditions and desired conditions. Load calculation methods vary, depending on whether the building uses mechanical, natural, or economizer ventilation.
