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

Joint collaboration for predictive maintenance in HVACR
