Governor Wolf Establishes Statewide Clean Energy and Energy Efficiency Goals in PA

Commercial Refrigeration, Energy Efficiency, Federal Regulations, HVACR, Industrial Refrigeration
The governor announced the new executive order at an event celebrating the public-private collaboration happening in the city of Pittsburgh to help bolster the city’s climate action plan.   The beauty of undertaking energy goals is that it is never just a 1:1 trade-off. There are numerous ancillary benefits, ranging from the obvious, giant elephant in the room that is the reduction of carbon emissions all the way to improved worker happiness because their employer's heating and cooling systems run more precisely and efficiently. Energy goals can be instituted at the consumer level (more energy-efficient windows), the corporate level (full-scale energy management systems), and the state/municipal level (larger electricity shares of solar or wind sources), and while each of these might not seem like they could move the needle much…

Customer Service and Food Safety are Most Important Factors for Cold Chain Customers, Survey Finds

Customer Service and Food Safety are Most Important Factors for Cold Chain Customers, Survey Finds

Commercial Refrigeration, Food Safety, Industrial Refrigeration, Performance Analytics
Earlier this year, the Global Cold Chain Alliance surveyed hundreds of cold chain customers and providers to gain insight into what was driving purchasing decisions and relationship. The results of the survey were published in a Customer Research Report.   If one were to quickly guess which factor in the cold chain process was the most important when it came to large-scale refrigerated storage and transportation, no one could fault you if you said cost. When considering millions upon millions of units that need stored, shipped, and delivered in a fluid, constantly changing world economy, it's a no-brainer that keeping the costs associated with such massive undertakings would be priority #1. But according to a Customer Research Report published by the Global Cold Chain Alliance (GCCA) this year, cost is…

Is HVAC/Refigeration Automation the Next Big Thing for IoT?

Is HVAC/Refigeration Automation the Next Big Thing for IoT?

Commercial Refrigeration, Energy Efficiency, HVACR, Industrial Refrigeration, Performance Analytics, Technology
As we throttle toward the end of this decade and into the future, the Internet of Things (IoT) continues to become more and more ubiquitous in our daily lives. On smaller scales, we see it in our homes with products that now merge thermostats with home security, or allow us to order items from Amazon through voice-activation. On a massive scale, we see it in the near-full automation of some global supply chains. And right in the middle of those ends of the spectrum, we're starting to see it become standard practice in the one place we spend most of our time: the workplace.   In particular, the HVAC/Refrigeration industries are beginning to catch up to the times and see the benefit of automating the operations that they can. Lighting,…

E. Coli Outbreak can be Learning Opportunity for Leafy Greens Industry

Commercial Refrigeration, Federal Regulations, Food Safety, Industrial Refrigeration, Produce
The worst E. Coli outbreak in over a decade has affected a widespread swathe of the country—reaching as far as Alaska—but seems to have originated from just one location: Yuma County in southwest Arizona.   According to public health officials with the FDA, the outbreak has sickened 197 people in 35 states, with five tragically having died. Officials also said that the contaminated supply of romaine lettuce has worked its way through the supply chain and is no longer available for consumption. So any immediate risk has passed.   And while everyone can breathe a sigh of relief that they are not currently at risk, the fact remains that an outbreak did still occur. This is a fact not lost on both public health officials and produce professionals in the…

"It's almost like the check engine light in your car."   This is how Charlie Sternberg, owner of S&S Refrigeration Co. in New Jersey, described the base value of NRM's monitoring platform to greenHVACR magazine. As a refrigeration technician, any tool that improves his ability to effectively—and efficiently—solve his own clients' issues is invaluable. And a tool specifically designed to offer the best, and most comprehensive, fault detection is worth its weight in gold. For Sternberg and his dedicated team of technicians, he found that sidekick in NRM's controls and monitoring platform.   "What the NRM system provides is real-time system functionality and control, energy savings, monitoring, and notifications of potential issues," he added. He's heard feedback from his clients that they are more at ease knowing their product is constantly…

In Connected, Smart Technologies, the HVACR Industry Sees a Real Game-Changer

Commercial Refrigeration, HVACR, Industrial Refrigeration, Technology
Some of the best places to gain insight on the future outlook of specific technologies or industries are trade shows, conferences, and educational sessions hosted by industry leaders. Often, a new technology or product will ignite a flurry of buzz and anticipation, but without a full understanding of its impact or integration into its particular market vertical. At events that gather the best minds of their industries, fleshing out what a new product, fad, or trend is, does, and affects, is usually a focal point for multiple speakers—most things are best viewed through multiple, different-colored lenses. This is especially true when the buzz is industry-wide and seemingly unavoidable.   In the world of commercial and industrial refrigeration, this particular maelstrom of a topic is smart technologies connected through The Cloud.…

Historically Cold Climate can Wreak Havoc on Air-Cooled Condensing Units

Historically Cold Climate can Wreak Havoc on Air-Cooled Condensing Units

Commercial Refrigeration, HVACR, Industrial Refrigeration
The historically cold temperatures gripping a lot of the country right now are not detrimental only to you, and your home heating bill; they are also increasing the likelihood of an operational issue in air-cooled condensing units.   The use of low pressure refrigeration controls (LPC) is mostly found in smaller, refrigerated boxes such as beer coolers. The temperature of a refrigerated box can be controlled by a low-pressure control (LPC), instead of a thermostat, because of the pressure/temperature relationship in the refrigeration system. By cycling the compressor in response to the suction (low side) pressure, box temperature can be controlled. For this type of control, the condensing unit must be in ambient temperature, higher/warmer than that of box's highest operating temperature.   Thus, when the temperature outside of the box…
