If improved filtering is insufficient to reach the desired IAQ, a further step
is to purify the indoor air. One way to achieve this is by using individual
room air filtration units. The sole purpose of these units is the purification
of the air. The introduction of such units does not affect the control
application of the conventional HVAC system.
The PM2.5 controller RDF870KN is used in combination with a PM2.5 room
air purifier (or fresh air unit with inbuilt PM2.5 filter) to control PM2.5
in individual rooms. This is shown in the figure below.
RDF870KN has setpoints for both PM2.5 and CO2.
