At a recent E360 Breakfast, Emerson hosted a panel discussion among HVACR contractors to glean their insights and opinions on the biggest challenges and emerging trends impacting their businesses. It was a valuable opportunity to get a working perspective on issues more often discussed by industry analysts. A recent article covers a wide range of topics, including talks of new, high-end technologies at a practical level. You can read the whole article here.

The new technologies, IoT and analytics in the field

In recent years, the HVACR industry has experienced an influx of new electronic controls, connected technologies and data analytics enabled by the internet of things (IoT). As these technologies have come online, each of the three contractors on the E360 panel, with companies and customer bases of different sizes, has had different degrees of experience and interaction with these technologies in the field — from working with component-level information to gathering insights on facility management.

Making better use of data and analytics in the enterprise

Jim Wharton, area vice president of Link Network, ABM in Atlanta, works with an enterprise-level customer base. He explained that while data collection capabilities have been available for decades in different forms of energy management systems (EMS), many operators don’t use them to their full potential. Many may glance at their facility dashboards, see multiple areas running in the red (out-of-tolerance conditions), and may simply ignore the potential problems. “Most operators know the way their building behaves, and if they see an alarm in a certain area, they also know whether it will go away or if they need to act on it,” he said. He added that advanced data analytics now offer more insights and the potential to add tangible operational value by helping to drive informed decision making, detecting performance trends and providing equipment diagnostics and troubleshooting.

Embracing new technologies at home

Residential consumers are also embracing whole-home automation, said Martin Hoover, owner of Empire Heating & Air Conditioning in Atlanta. He said that his customers love getting notified of routine maintenance items, such as when to change filters or fix a water clog or leak. But most importantly, homeowners are using these systems to diagnose problems. “They like the fact that their home automation systems can let us know if something’s broken, so we can fix it before it affects their comfort levels,” said Hoover. But from a contractor’s perspective, he stressed that a home system also helps properly trained and educated technicians perform their own diagnostics. “This doesn’t allow us to take someone straight out of high school and put them in the field, but it certainly makes it easier,” he added.

On-board compressor controls are also helping service contractors gain deeper insights into overall refrigeration system performance. Michael Duffee, owner of Restaurant Equipment Services, Inc. of Tucker, Ga., cautions that these advanced controls require trained technicians. “If they’re not familiar with the technology, then you have to train them to avoid misdiagnosis, as there’s still the potential for things to go wrong,” he said.

Developing new technology for the real world of refrigeration

Designing new sensor technologies to be resistant to the impacts of weather, water and humid conditions are also very important considerations for Duffee. For example, he said, “In walk-in cooler environments, where it’s wet and sometimes caustic with the food and so forth, we’ve seen issues with consistency and where sensors and microprocessors can cause problems.”

With our broad knowledge of the full range of commercial refrigeration applications, Emerson keeps these environmental considerations upfront as we develop and introduce next-generation sensors and controls. For applications as simple as automated residential controls or as the source of real-time data for enterprise and IoT analytics, Emerson continuously consults with end users on the real-world issues raised by new technology.
