4. Basic

principles for planning

The basic principles for planning described below are theoretical ones. In practice, the necessary
humidification capacity is influenced by parameters that can not be covered by this documentation.
For this reason, the values that were determined in theory have to be complemented by practical
values or corrected in many cases. Our advisors will be pleased to assist you.

4.1

Notes on the planning of air humidification systems in one area

Proceed as follows when selecting and/or dimensioning the air humidification system BS:

-

Determining the volume of the room and the air changes

-

Determining the set points (temperature and humidity/relative humidity)

-

Determining the humidification areas

-

Calculating the maximum humidification capacity

-

Defining the device requirements

The chapter below contains all necessary pieces of information on the individual planning steps.
For every planning step, a calculation example based on assumed system data has been
included. The three different examples are supposed to illustrate the procedure. Naturally it is not
possible to cover all applications by means of examples. The air humidification system BS offers a
variety of solutions for individual air humidification in a large variety of rooms .

If you have any further queries or problems, the NORTEC sales team will be glad to help.

In this case, only one room is to be humidified. As every atomiser is fitted with its own hygrostat,
different zones within one area (room) can be humidified individually.

EXAMPLE 1

A DRAABE air humidification system BS for direct room air humidification is to be installed in the
paper store of a large printing works. The following data is available:
