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…
