3.1 Introduction
Because of the modular design and different components used, we can only show below the
basic structure of the DanX AF unit. If you are in doubt how to assemble the different
modules, please ask our distributor for an exact drawing of the unit. Please refer to the type
plate on the inspection side of the unit to find out what type of unit you have to install.
The units shown in the drawings are all left hand units. If you have a right hand unit all
components of the unit are the other way around.
Assembly of the DanX modules should only being carried out by trained specialists
or by
people supervised by authorized staff. It is the responsibility of the fitter to read and
understand this guide and other given information.
3.2 Unit construction and function
The DanX - AF consist of a compressor driven heat pump with only one air direction. The
cooling circuit is ready mounted, filled with refrigerant and do not need any extra installation.
If the unit is ordered with an outdoor air intake, a damper is mounted on the top of the AF
module as shown in the drawing.
The DanX - AF is mainly used as a recirculation system with a minimum outside air mixed
into this air stream, which is required for hygienic reasons for the pool hall. To run this
system an extra extract fan is required to avoid overpressure in the swimming pool hall. The
dehumidification is mainly done in
the cooling circuit’s evaporator, but assisted by the fresh
air entering the swimming pool through the AF system. The energy which is extracted in the
evaporator is again added to the swimming pool air in the cooling circuit’s condenser, just
after been mixed with the outside air.
For further explanations about the controls of this unit, please refer to the manual of the
control panel.
From left to right the following components/modules have to be installed:
1)
Supply air fan.
2) AF module with heat pump and heating coil.
3) Return air filter*.
*If a panel filter is installed, the filter will be built in into the AF section, why there will be no
separate filter section.
If the DanX - AF is delivered with an outside air damper a separate fan (not delivered by
Dantherm) has to be mounted to extract the same amount of air from the swimming pool hall
as the DanX - AF takes in through the outside air intake in the top of the unit to keep the air
volume in the swimming pool hall in balance. At the same time an outside air filter (not
delivered by Dantherm) should be mounted in the outside duct system to avoid dirt coming
into the DanX - AF unit.
