8. Set-up and commissioning
Set-up
a) Inside the room to be dehumidified:
The device works with air circulation. The regeneration supply air is to
be supplied from the outside while the regeneration exhaust air is to be
released to the outside.
b) Outside the room to be dehumidified:
The device can be connected in air circulation or through-air operation
mode. In this respect, connection must be established between the dry-
ing air and the room to be dehumidified.
Installation
The pipelines or hoses must be designed for the applied static pres-
sure by the fans. Air hoses are to be laid out in a straight line and
outstretched.
The regeneration exhaust air line must be laid out with a slight slope
to prevent potential condense water from flowing back into the de-
vice or disturbing the air flow. If the air line is to be laid out in a ris-
ing direction, a discharge is to be provided for condense water. As a
precautionary measure, the exhaust tube can be insulated.
To prevent an air short circuit with the humid exhaust air, the humid
air outlet of free-intake devices is to be laid away at a minimum
distance of approx. 1.0 m from the device.
Presettings
Ventilation devices are generally equipped with one or several fans with
sufficient dimensions to overcome resistance in potential pipelines or
appliances. In most cases, their speed cannot be adjusted. To set the
required air flow for the respective application, the hydraulic adjustment
is to be carried out by means of throttle valves installed downstream and
upstream of the fan. However, this leads to an unnecessary and often
considerable increase in noise and energy consumption.
