Monitoring of cooling systems
Increases in ambient temperature can, of course, be
caused by degradation or even failure of the cooling
systems such as fans. These need to be maintained,
like every other component and monitored
continuously in real time to ensure that their
performance has not dropped below the required
level due to wear or to a buildup of dirt in the
airway.
Suitable sensors are available to help with this
task. Omron’s D6F-PH digital pressure sensors for
air flow and clogged filter detection in heat recovery described in this article fully achieves this goal.
units do this by detecting the differential pressure Wide angle IR sensors identify hot spots wherever
