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.

Five Prestigious Reasons to Become an HVACR Apprentice

BobLabbett_Blog Bob Labbett | V.P. – Aftermarket Distribution, Cold Chain

Emerson Commercial & Residential Solutions

As National Apprenticeship Week (March 4–8, 2019) once again approaches, the critical shortage of qualified HVACR technicians within the U.S. continues with an estimated industry shortfall of 118,000 technicians by the year 2022. Recruiting apprentice HVACR techs remains as challenging as ever, because students with an aptitude for technical trades are not being encouraged to pursue vocational or technical training. Students need to be convinced that an HVACR career path is a viable alternative to a four-year college degree, offering them a chance to work on new and emerging technologies in meaningful careers that contribute to society.

What’s stopping them? One is the perception among American high school students that a college degree is more valuable and prestigious than an apprenticeship and a fast track to a career. The other is that we collectively as an industry are not adequately presenting them options. Here are five great reasons for a high school student to consider becoming an HVACR apprentice.

  1. College is more popular — and more expensive — than ever.

At least two-thirds of the high school class of 2020 intend to go to college; this represents the highest rate of secondary education attendance in U.S. history. They and their parents know that college is getting more expensive, while financial aid is shrinking. The average student graduates with an average of $40,000 in student loan debt just as they’re about to begin looking for an entry-level job. What isn’t as well-known is that about half of all college students drop out without earning a degree — and with no real job skills. Yet schools, guidance counselors and peers continue to push students straight to college.

  1. There is an alternative: A fast start — with no debt.

When many “traditional” students are just starting their sophomore year in college, some of their high school friends will be beginning their careers as HVACR apprentices with average entry-level salaries ranging from $47,000–$60,000 a year, depending on skill set. It’s a matter of supply and demand, and being an HVACR tech is a vocation in extremely high demand. It’s time high school guidance counselors had information about alternative apprenticeships on hand.

  1. An apprenticeship is a wise path for students who can use their heads — and their hands.

A bright student with some high school courses in math and/or physics can learn to read a blueprint and earn an HVACR apprentice certificate at a community college in six months to a year, at little or no cost and with no student debt. Others can even start straight out of high school, getting paid while earning their certificate on the job. In an industry that needs 118,000 new HVACR apprentice technicians, their certificates mean they are almost certain to get job offers from almost any company to which they apply. As an apprentice, their future career tracks are limited only by their ambition and drive (or lack thereof).

  1. An apprenticeship is a top-notch education.

An HVACR tech certificate may not sound as glamorous as a college degree. But four years of on-the-job training in a technical field are easily the equivalent of a four-year academic degree. HVACR techs are responsible for maintaining healthy environments at major medical centers. They work in the aerospace industry and in high-tech corporations. HVACR techs know how to maintain and repair 12-ton coolers, heat pumps, furnaces, ultralow-temperature freezers and refrigerators; they can manage the electronic systems that connect them; and they can run the software and internet programs that monitor and control them. HVACR techs work with advanced technologies, doing essential work that significantly affects people’s lives.

  1. They’re wanted.

The HVACR industry is working with educators, unions and contractor organizations to make it even easier to earn apprentice certification, with more online courses, night classes and technically advanced curriculums to create valuable on-the-job training. Even the federal government has stepped in, with the Strengthening Career and Technical Education for the 21st Century Act providing funds for students who are looking for more career-oriented education after high school.

 

Are You Up for the Challenge?

We have discussed Emerson Climate Technologies’ transition from mechanical pressure switches for system control and protection in refrigeration equipment to electronic controllers onto Copeland™ condensing units with its Electronic Unit Controller in recent blog posts. This advanced device replaces all mechanical pressure controls, simplifying set-up and provides better performance with reduced call-backs.

In an effort to generate awareness, increase comfort, and educate HVACR professionals, Emerson has developed a platform to support the transition called the “One Minute Challenge.” This campaign was designed to help contractors overcome the “black box” syndrome of using new technology and to create awareness that this game-changing piece of technology simplifies commercial refrigeration system operation while increasing system accuracy, protection, and capabilities. The One Minute Challenge is an online simulator that shows users how they can now complete a standard, 25-minute job in 1 minute.

Here’s how it works:

  • The online simulator allows the user to set-up the electronic unit controller as if they were on the actual jobsite. It times how long it takes each user to complete, and it establishes a leader board showing the top 20 contractors and wholesalers. The tool can be used on iPads and other tablets, as well as a computer.

The top five leading wholesalers and contractors include:

Contractors:

  1. John Tillack, Poleward Refrigeration – 7.90 seconds
  2. Bob Smith, Bob’s A/C – 9.54 seconds
  3. John Jones, Jones HVAC – 13.92 seconds
  4. Lee Page, Equipment Service Company – 14.03 seconds
  5. AJ Milbes, Rio Ranch Market – 15.17 seconds

7.90 seconds is the top time to beat in the One Minute Challenge! Do you think you have what it takes to dominate the top? See for yourself just how easy the Electronic Unit Controller is.
