Leveraging Energy Management System Data for the Greatest ROI

Leveraging Energy Management System Data for the Greatest ROI

Energy Efficiency, HVACR, Performance Analytics, Technology
Across nearly every industry-type, regardless of their location, size, product offerings, or customer base, businesses are feeling the pressure to do more with less. In our world--companies with commercial or industrial refrigeration systems like walk-in coolers and freezers, and refrigerated warehouses--it's a top-of-mind consideration. Whether it's a kitchen in a chain of restaurants, or a multi-site cold storage facility, streamlining aspects of their operation are seen as necessities to remain not only profitable, but competitive. Staff are needing to wear multiple different hats, so to speak, more and more, and day-to-day operations are scrutinized with huge microscopes for any area, no matter how small or trivial it may seem on the first look, where things could be done better or more efficiently.   All of these companies also have one…

Inefficient Refrigeration Compressor? It Could be the Pressures

Inefficient Refrigeration Compressor? It Could be the Pressures

Energy Efficiency, HVACR
When refrigeration service technicians respond to one of their clients' service calls, they tend to find the same issues over and over. The most common, and obvious, reason for a service call is a space temperature that is too warm. And, just as common, is suction pressure and/or head pressure being involved in the cause. Often, the refrigeration system will still run, but it'll run inefficiently because the suction pressure is too high while the head pressure is simultaneously too low.   This poses a risk to product quality, integrity, and safety.   On the outset, this exact issue may not be easily observed because, again, the system will call for cooling as it should but it won't be doing so in an effective or efficient manner. In such cases,…

Compressor Short Cycling: A Hard-to-Find Energy Waster

Compressor Short Cycling: A Hard-to-Find Energy Waster

Energy Efficiency, HVACR, Performance Analytics, Technology
In commercial applications, one of the most important tasks in keeping components running at their peak performance is determining what’s a cause and what’s a symptom if mechanical problems arise. The difference between knowing and not knowing could be thousands of dollars worth of diagnosis.   In particular, short cycling seems to be one of those refrigeration and HVAC terms that gets murkier the deeper you get into the water. This blog post will explain what short cycling is, why it’s harmful for your system, and what issues it is born from.   First thing’s first: what is short cycling?   Short cycling occurs in your compressor when a mechanical failure is causing the run times to terminate prematurely and since set point has not been achieved, it restarts shortly…

Refrigeration Problem of the Week: Solenoid Valve Stuck Open AGAIN

Refrigeration Problem of the Week: Solenoid Valve Stuck Open AGAIN

Energy Efficiency, HVACR, Performance Analytics, Technology
In this new weekly blog series, NRM will highlight an issue a customer had and was able to resolve with our industry-leading control and monitoring solutions. Some of the most serious refrigeration problems can go undetected and result in equipment failures and/or product loss.   Problem of the Week: Pesky Solenoid Valve is Stuck Open Again   As is often the case with large, complex systems that we don't personally have the appropriate knowledge or training for, owners/operators, mangers, and regular staff usually regard their business' commercial or industrial refrigeration equipment with an "out of sight, out of mind" mentality. Without the necessary technical expertise to professionally diagnose a problem, they either pay the system little to no attention, or interact with it and don't consider the consequences (because they're not aware…

In the Grocery Game, Refrigeration and HVACR Must Keep Evolving

In the Grocery Game, Refrigeration and HVACR Must Keep Evolving

Commercial Refrigeration, Energy Efficiency, HVACR
As corporate goals in the grocery industries continue to evolve—with energy efficiency, sustainability, and wanting systems that provide more "bang for your buck" leading purchasing decisions—so too are the refrigeration systems being developed these days.   Don Newlon, Vice President and General Manager of Emerson's Commercial and Residential Solutions division, advises manufacturers to keep customer's wants over their own.   “Customers aren’t pursuing refrigeration architecture because of the architecture itself but because of the benefits they want to receive from it,” Newlon said. “Choosing a refrigeration system used to be all about energy efficiency, but many customers today have different things they’re trying to optimize. Energy efficiency is still important, but many customers also are seeking to reach environmental or sustainability goals — in fact, for some, that’s their primary…

Massachusetts Wants 80% Clean Energy by 2050, and New Regulations are Coming in 2018

Massachusetts Wants 80% Clean Energy by 2050, and New Regulations are Coming in 2018

Energy Efficiency, HVACR
In response to a stunning 2016 ruling by the state's Supreme Judicial Court, in which the court sided with an environmental group claiming Massachusetts didn't do enough to strive for its 2008 energy goals, the state set forth new regulations last month.   Although it took a proverbial fire lit under its tail, Massachusetts ramped up state regulations last month to propel its clean energy goals back to the top of the most lofty in the country.   In 2014, the Conservation Law Foundation, a leading national environmental group, filed a lawsuit against the state arguing that the state did not adequately develop regulations needed to comply with the 2008 Global Warming Solutions act. Fast forward to 2016, and the state's Supreme Judicial Court sided with the environmental group, ruling…
