Penetration of predictive maintenance in HVACR
equipment is projected to rise heavily
The increased focus on predictive maintenance is one of the
major trends being witnessed in the HVAC equipment market in
Europe 2018-2022.
The need for data collection and analysis to solve complex
industrial HVAC maintenance tasks is driving the demand for the
Internet of Things (IoT)-enabled devices. […]
Predictive maintenance reduces the overall downtime and
increase operational efficiency due to which end-users have
shifted their focus towards it.

Condition monitoring & predictive maintenance are
decisive for commercial HVACR systems
› Heating, ventilation, air conditioning, and refrigeration (HVACR) domain part
of a building’s critical infrastructure – risk of failure has to be minimized, especially
in public buildings such as airports, hospitals, etc.
› Unscheduled downtime of HVACR systems causes severe costs overruns for
building operators and/or HVACR maintenance service providers
› Up to 40% percent of commercial HVACR systems are a potential market for
predictive maintenance solutions according to interviewed experts
Introduction
› Smarter and connected HVACR devices have huge potential for providing
value-added services by implementing additional sensors to enable condition
monitoring and predictive maintenance
› HVACR system understanding is crucial to identify potential fault events and
enable meaningful, valuable and actionable data collection from the systems

Based on market feedback, potential maintenance
issues have been analyzed for a reference design
› Based on expert interviews, compressor, fans/motor, and piping most likely to
fail with critical impact on the overall system
› To show potential impact of condition monitoring & predictive maintenance, joint
HVACR reference kit is in development between Amazon Web Services (AWS),
Klika Tech, and Infineon
› Kit shows potential of sensor-enabled condition monitoring & predictive
maintenance for HVACR and represents a reference system for customization

How barometric pressure sensors enable condition
monitoring in HVACR devices
› Miniaturized absolute digital barometric air pressure sensor
with temperature sensor
› Ultra-high precision (±2 cm) and low current consumption
› Environmentally resistant package with 50 m under water for
one hour (IPx8)
Venturi effect: reduction of fluid pressure when
fluid flows through a constricted section of a pipe
Bernoulli equation:
