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.…

HVACR Contractors: the Key to a Healthy Relationship with Your Customers? Communication

HVACR
In the relationship between HVACR contractors and their customers who rely on the complex, expensive refrigeration equipment to keep their business alive, neither partner has it easier than the other. Especially when that relationship exists in the restaurant and service industry. Both restaurateurs and contractors work long, hard hours, maintain operation no matter the weather, and both face growing regulatory challenges, as well as competition. Like a marriage between two workaholic people, finding a balance—that "sweet spot" of understanding, needs anticipation, and support—is the key to a healthy and prosperous partnership. And whether a business relationship between two entities, or a romantic relationship between two bodies, communication is the soil in which to plant the seeds for a happy future.   Take Georges and Claudie d'Arras of Olmsted Falls, Ohio,…

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,…

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…

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…
