Appendix 3 DC Power consumption of the AQM 65
Occasionally mains AC power is not available at the site where the AQM 65 is installed and an
alternative power solution is required. There are two variables which determine the power
requirements in Watts (W) for an AQM 65.
The
number of modules
installed in the AQM 65: more modules demand more power.
However the power demand of all the modules combined is small compared to the overall
power demand of the AQM 65.
The
outside temperature (

C)
. The external temperature will place power demands on the
thermal management system (TMS), the heaters and compressor used to stabilise the
internal temperature of the AQM 65. The power demand of the TMS system is higher than all
of the modules combined.

[W] power
demand occurs for short periods of time, but can occur regularly.
Cooling requires more power than heating, therefore the power demands can be greater in hot
climates than in cooler climates.
The modules demand power but also generate heat in the AQM, so (counterintuitively) AQMs with
more modules may not significantly increase the overall power demand.
Here is a general guide, describing the power demands for AQMs of different module configurations
under different external conditions.

Aeroqual provides an AQM 65
power demand calculator
(an Excel .xls spreadsheet). You can
download the calculator and instructions on how to use it from the AQM 65 online training system.
The power demands have been
measured under real conditions
using an environmental chamber
capable of achieving the temperature ranges described in the table.
