As refrigerant regulations grow more stringent, manufacturers are beginning to offer new refrigeration architectures that utilize low-GWP refrigerants.

While large grocery stores are not going away any time soon, there is a new trend taking hold in the marketplace: the small-format grocery store.

Grocers are becoming more vigilant in keeping their refrigeration equipment as clean as possible.

The equipment and components in this showcase are designed to appeal to both end users and the people who work on them in the field.

The Showcase is designed to educate contractors about the new commercial and industrial refrigeration products available.

Target and Amazon have both recently announced plans to construct new stores that contain CO2 refrigeration systems, which will help the retailers significantly reduce carbon emissions and energy use.

From ice machines to reach-ins to controls to components, the Showcase is designed to educate contractors about the new commercial and industrial refrigeration products available, so they can help their customers make the right choice for their application.

In an informative session at the NASRC’s Sustainable Refrigeration Summit, Publix and Coborn’s shared the pros and cons of incorporating CO₂ refrigeration systems into their stores.

These Emerson half-day CO₂ transcritical booster supermarket refrigeration courses will take place March 28, 29, and 30 at the Energy Education Center in Irwindale, California.

EPA recently expanded its list of acceptable refrigerant substitutes for new refrigeration equipment to include R-471A and R-515B.

At the AHR Expo, manufacturers displayed their latest commercial refrigeration equipment, which included condensing units, components, controls, and other solutions.

A New Hampshire grocer installed the innovative FlexCube refrigeration system, a modular technology using the A2L refrigerant R-454C, in his new store.

Refrigerant manufacturers highlighted their low-GWP refrigerants for both air conditioning and refrigeration applications at the 2023 AHR Expo.

Air conditioning and refrigeration are marvelous inventions and have a transformative impact on comfort and health, underscoring their irreplaceable role in modern living.

A new survey released by Daikin studied the opinions and habits of more than 1,200 people from 12 cities across the globe when it comes to their a/c systems.

The transition to A2L refrigerants will offer benefits to the environment, as well as business challenges for HVACR OEMs, distributors, and contractors.

RDSs are generally required in A2L systems that contain more than 4 pounds of refrigerant and can either be field or factory-installed, depending on the manufacturer.

Manufacturers are offering low-GWP refrigerant alternatives, as EPA is proposing a 700 GWP limit for most new comfort cooling chillers starting in 2025.

By splitting the absorption process into two steps, lithium bromide solution concentrations are lower in the system, enabling lower hot water temperatures within the generator, lower hot water flow rates, and the elimination of crystallization risk within the chiller.

Chillers are being used as heat pumps, outfitted with heat-recovery systems, used in building electrification projects, and installed in arrays to cool data centers.

With a double brood of cicadas forecasted to awaken, now is the time to prepare for how to deal with the mess they will leave behind and the potential damage they can do to equipment.

Advancements in technology have brought a lot of opportunity to the tool market, with items like reporting, mobile apps, and wireless data transmission.

When servicing a refrigeration system, it is important to accurately determine the true cause of the failure. Misdiagnosing the problem can often create additional system issues for you and the customer.

The most important features of electronic measuring devices have been established in customer surveys and are discussed in this article.

Now available with Bluetooth, this product provides users full access to all features of their devices, such as apps and email.

Technicians have the choice of using either a digital or mechanical manifold gauge. Each one has its benefits and disadvantages, which is why it may pay to own one of each kind.

Thermostats are like other pieces of interactive equipment: People are thrilled by each development but move on quickly when the next feature comes along.

It’s the contractor’s job to ensure consumers understand the functionality of smart thermostats without becoming overwhelmed by the features and data.

Smart thermostats offer preventive maintenance options and rebates for customers, but contractors should be sure to get educated — and educate homeowners — on utility rebates like demand-response programs.

Through the new integration, ecobee thermostat owners who also own Generac home standby generators can easily see the status of the generator and remedy potential issues.

Winners of the The NEWS’ eighth annual Dealer Design Awards’ HVAC Commercial Equipment category have brought new ideas to the commercial market that should help contractors meet the commercial challenges they face.

Heat-only, direct-fired, and indirect-fired makeup air units have been added to the company’s product line. 

A lot of refrigerant reclaimers aren’t charging for mixed refrigerants anymore, which may in turn, mean an opportunity for HVAC contractors to make more money.

The EPA initially faced backlash from the industry regarding the sell-through mandate for certain HVAC systems. The Agency revised the provision by allowing one additional year, until January 1, 2026.

Food retailers shared their concerns and experiences with refrigeration systems that use alternative refrigerants at the Food Marketing Institute’s (FMI’s) 2023 Energy & Store Development Conference.
