Transforming Data Into Maintenance Insights

Today’s supermarket, restaurant and convenience store operators have an abundance of data at their fingertips. Most utilize facility management systems and controls to monitor refrigeration, HVAC, lighting and energy management. These platforms give them ability to respond to alarms that could impact customer comfort and food quality. But alarms are only the “tip of the iceberg” when it comes to this data’s potential usefulness. In a recent E360 article, we discussed how operators can transform this data into maintenance insights.

While many companies spend their time tracking, prioritizing and responding to alarms that need immediate attention, owners and operators have relatively limited visibility into overall operational status. But with deeper analytics of available data, operators can look “beneath the hood” of key systems and gain access to insights that could impact them in the future — insights that could potentially transform maintenance activities from a primarily reactive approach to a more condition-based, analytics-driven model.

The difference between “urgent” and “important”

One way to visualize the role of operational analytics in maintainance activities is by prioritizing maintenance events according to their urgency or importance. Maintenance events and operational decisions can be divided into four basic categories:

  • Don’t roll a truck (no action required)
  • Roll a truck soon (plan to take action)
  • Roll a truck now (take action now)
  • Take steps to improve (address at next scheduled maintenance)

Using the iceberg analogy, urgent issues represent events that you will need to respond to immediately — those that lie above the surface. Below the surface, you’ll find issues where analytics platforms can help operators make maintenance decisions based on their potential business impacts. Analytics can help identify issues that, while not urgent, are highly important — and may have otherwise gone unnoticed.

These insights often reveal areas of improvement that could either be addressed during scheduled service intervals or when the equipment or system condition indicates the need to address a potential issue. Armed with this knowledge, operators can receive advance notice of certain performance issues that may soon impact them.

Drive performance across the enterprise

The role of analytics within a maintenance framework can be extrapolated across an enterprise to maximize its potential. Drawing from a combination of equipment sensors and control system data, performance analytics can provide store operators and enterprise managers deeper insights for:

  • Real-time and historic operating conditions in their facilities and systems
  • Pressure, temperature and energy data to compare to established benchmarks
  • Enterprise- and store-level dashboards and prioritized notifications

For example, analytics allows for display case performance analysis based on temperature sensor data. Data may detect an anomaly in case temperature deviations that, while still within safe ranges, could indicate a larger performance issue. Instead of being notified with an urgent alarm, operators have advance notice to investigate issues at their discretion — and even preempt a potentially larger issue.

Enterprise operational dashboards can also be configured to display these insights and provide managers with visual snapshots of urgent and pending issues across their store networks — even enabling investigation into specific assets in their respective facilities.

If you’re ready to see what lies below the surface of your operational data and realize the true potential of analytics, contact Emerson to speak to one of our enterprise data analytics experts.

National STEM Day is Nov. 8. From Emerson’s perspective, it’s a day to recognize the importance of science, technology, engineering and math — not only in our education curriculum, but also in the heating, ventilation, air conditioning and refrigeration (HVACR) industries.

Bringing the Need for Qualified Technicians Into Focus on National STEM Day

Bringing the Need for Qualified Technicians Into Focus on National STEM Day

With the commercial refrigeration industry evolving to utilize more sophisticated technologies, technician jobs are becoming more technological than mechanical — and becoming viable options for those pursuing a STEM career path. A new workforce recruitment initiative by the Heating, Air-conditioning and Refrigeration Distributors International (HARDI) is addressing the technician shortage head-on via a new full-length documentary.

HVACR supply chain feeling the impacts

The impacts of the service technician shortage are being felt throughout the HVACR supply chain. While the vast majority of HVACR contracting business owners today are actively looking for technicians, this pain has far-reaching consequences — from wholesaler distributors to end users, owners and operators. Whether you’re operating a supermarket, c-store, restaurant or virtually any facility that has HVACR needs, the lack of qualified technicians is making it increasingly difficult to find reliable sources for new installations, routine servicing or emergency repairs.

And while industry stakeholders have been sounding the alarms for nearly a decade, it’s a problem that’s not going away. According to the U.S. Bureau of Labor Statistics, HVACR mechanic and installer jobs are expected to grow at a rate of 15 percent nationwide through 2026.

A perfect storm of market trends, technological advancements and demographic changes are compounding the issue. This is especially true in refrigeration, where shifting store formats and environmental regulations have led to a proliferation of system types. These systems are introducing connected technologies, electronics and alternative refrigerants, many of which represent completely new servicing procedures. As the industry struggles to attract a new generation of recruits, many of our current service technicians are scrambling to keep pace with these system changes, or are planning for retirement.

HARDI releases “Hot Commodity”

The goal of HARDI’s new workforce recruitment initiative is to spread awareness of the HVACR wholesale distribution industry to the younger generation and encourage these individuals to pursue an HVACR career path. To spearhead this effort, HARDI is releasing a documentary that exemplifies their mission and explores the many HVACR-related career opportunities.

While the full-length film has yet to be released, HARDI is currently promoting a short trailer of the documentary. As one of the professionals featured in the film states, now’s the time “for the younger generation to carry the ball” forward.

The themes presented in the documentary include:

  • Alternative to traditional college — Many high school students are encouraged to attend college, even if it’s not necessarily the best fit. Vocational and technical schools offer an alternative to traditional college, while allowing attendees to begin earning a living as they learn.
  • Financial viability — With a median annual salary of $47,080, HVACR technician profession earnings are significantly higher than other occupations, even though the job doesn’t require a four-year degree. As one of the contractors in the film explained, it’s possible for service technicians with 10 years of experience to earn as much $100K per year. Increased demand for these jobs is driving salaries upward.
  • Variety of career paths — Whether you’re coming out of high school, or college, or seeking a career change, there are multiple opportunities and positions to explore. For example, the film mentions a microbiologist who sought a career change offering the potential to achieve ideal indoor air quality.
  • Changing perceptions — The perception of working in a dirty, dark and dangerous environment is changing. The next generation of HVACR technicians will work with rapidly changing, emerging technologies, electronics, computers and more.
  • Evergreen market — Achieving ideal air quality and reliable refrigeration in a dynamic market is an evergreen opportunity. As a result, HVACR professions are among the most sustainable across all occupations.

 

As a HARDI supporter and long-time champion of this cause, Emerson will continue to do its part to raise awareness of the technician shortage facing our industry. Our Educational Services group frequently partners with vocational and technical schools to donate equipment, offer training and career advice, and even judge HVACR-related competitions. Look for the full HARDI documentary to be released later this year.

Emerson Commercial & Residential Solutions

Emerson is applying our expertise in commercial refrigeration and AC toward building predictive models for a variety of applications and architectures, a foundation for the emerging artificial intelligence technologies in the HVACR industry. I recently discussed our work in ACHR News magazine, “The Impact of Artificial Intelligence on HVACR.” You can read the full article here.

The building blocks of artificial intelligence (AI)-enabled equipment and systems in HVACR are already well in development: next-generation sensors and controllers, increasingly sophisticated predictive analytics, and machine-to-machine learning (M2M) software, cloud data storage and the growing implementation of the internet of things (IoT). These tools are already providing opportunities to improve comfort, save energy, reduce maintenance costs and extend equipment life, all while helping end users better manage their operations.

But integrating these tools into true AI solutions — data- and algorithm-driven applications that will enable systems and equipment to learn and automatically perform critical tasks without human intervention — is a challenge that will require a deeper understanding of the complexities of equipment, HVACR architectures and building systems.

At Emerson’s innovation centers and in customer field trials, we’re tackling this challenge head on — but methodically. Rather than simply throwing more technologies into the mix, we’re leveraging our deep refrigeration domain expertise to simplify complexities and uncover insights into the industry’s most common refrigeration scenarios. We are in the process of understanding how deeply AI could be implemented into equipment and buildings, and how effectively it could help solve the industry’s biggest challenges.

As I stated in the article, Emerson is researching how some newer AI-related technologies can be utilized for more advanced services, such as detecting problems faster and pinpointing which actions need to be taken. For example, we are already incorporating some AI-related technologies into equipment when we learn they add value, such as sensors that warn of refrigerant leaks in supermarket refrigerants.

However, delivering on the promised value of AI — autonomous predictive analysis and control of HVACR equipment and even entire building environments — will require more than simply installing connected sensors and devices, transmitting clouds of data, and creating libraries of algorithms. As the automobile industry has learned, building a self-driving vehicle is a far more complex undertaking than it appears. This example is important to keep in mind when considering the inherent complexities and diversity of commercial refrigeration applications.

A typical commercial refrigeration system consists of many interdependent components — often from multiple suppliers — with potentially diverse data sources. The proliferation of system architectures and refrigerants has resulted in an ever-expanding diversity of applications. This makes data modeling and defining predictive algorithms difficult. At Emerson, we believe that the development of AI in HVACR will grow as an iterative process, via data processing performed at the equipment level — with tighter integration of sensors and controllers providing richer data to cloud- and IoT-based services. These services provide both real-time alerts and historical trends of equipment performance under a given set of conditions — including indications of potential failures.

These data sets are the foundation of the next level of AI, enabling predictive maintenance models that will anticipate problems and maintain optimum conditions across a defined range of variables. Reaching that point will require generating sufficient historical data detailing the operation, failures and problems of equipment and components. And while much of this data is available today, new sensors may also be required to provide more advanced predictive capabilities.

Relatively speaking, the use of AI in HVACR equipment and controls is still in its infancy. But we’re working to accelerate its advancement to help our industry reap its potential benefits, including: improved reliability, energy savings, prolonged asset life and, of course, predictive analytics. As more AI-related technologies arrive in the HVACR space, we’ll start to fully understand the significant benefits and valuable data they are capable of providing.
