3 Product Overview
3.1 Calculatingthemaximumrequiredsteamcapacity
The maximum required steam capacity must be calculated based on one of the following formulas:
mD: maximum steam demand in kg/h
V: volume of supply air portion per hour in m3/h (for indirect room humidication) or room volume to
be humidied per hour in m3/h (for direct room humidication)
ρ: specic gravity of air in kg/m3
ε: specic volume of air in m3/kg
x2: desired absolute room air humidity in g/kg
x1: minimum absolute supply air humidity in g/kg
The values for ρ,ε,x2and x1 can be gathered from the h,x-diagram or the Carrier-Diagram for moist
air respectively.

10 Product Overview
