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

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…

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,…

When is it Time to Consider a Refrigeration Monitoring and Control System?

When is it Time to Consider a Refrigeration Monitoring and Control System?

Commercial Refrigeration, Energy Efficiency, HVACR, Industrial Refrigeration, Performance Analytics, Technology
As more and more companies incorporate aspects of IoT and smart technologies into their day-to-day operations—from adaptive air-conditioning controls to motion-activated office lights to inside air quality sensors—one area for substantial improvement continues to be overlooked: commercial and industrial refrigeration. Most people couldn't live without their car dashboard warnings, their smart phones, or their cloud storage of pictures, videos, and documents. These types of technologies have radically changed how we interact with and use data. At a rapid pace, it's being adopted across any and all industries, but still, mostly except for one.   Ask yourself these 10 questions to consider whether or not it's time for your business to procure a refrigeration monitoring and control system.   Have you lost a compressor before?   We will start the list…

2017 Sees the Finalization of New WICF Regulations for Energy Efficiency; Compliance by 2020

2017 Sees the Finalization of New WICF Regulations for Energy Efficiency; Compliance by 2020

Commercial Refrigeration, Energy Efficiency, HVACR, Industrial Refrigeration
On September 7th, 2017, the U.S. Department of Energy put into place a new set of standards that revolve around walk-in cooler and freezer efficiency metrics. These new rules are now officially law. This passage concludes a three-year process that saw much back and forth, and faced doubts over whether it would ever actually materialize.   In the table below, which can be found in this article by ACHR News, the updated standards are expressed in terms of annual walk-in energy factor to the energy required for the refrigerated load.   [caption id="attachment_475" align="aligncenter" width="900"] The table displays the new standards for WICF energy efficiency metrics[/caption]   These new standards will have an impact on a wide range of refrigeration systems. They will affect everything from low-temperature dedicated condensing systems,…

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…

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…
