The NSF is providing a grant to six universities, which will work together to create sustainable refrigerant technologies.

New report finds that GHGs can be reduced significantly through the use of reclaimed refrigerant versus producing and using newly manufactured virgin refrigerant. 

A new technology has been developed that can decompose refrigerants, using a catalyst made from industrial waste called “red mud.'’ 

Compressor manufacturers have been improving the products on multiple fronts in recent months.

NASRC will offer free comprehensive CO₂ and propane refrigeration training at its Natural Refrigerant Training Summit.

Overly Hautz Co. announced that the U.S. Patent Office has issued US Patent 9,973,056, entitled “Motor Mounting Assembly and Method of Manufacture.”

Home builders need to begin preparing for the big refrigerant shift that is quickly approaching.

In Greek mythology, Argus was a son of Zeus. Having the king of the gods up on Mount Olympus for a dad probably raised the bar in terms of expectations. Fortunately, Tecumseh seemed comfortable with that kind of lofty namesake for its biggest launch at this year’s AHR Expo, the ARGUS condensing unit platform.

The grant will provide state-of-the-art technology and equipment for industrial training programs such as mechatronics, information technology and cybersecurity, HVAC, construction management, welding, and more.

Available for commercial and industrial applications, this product supports safety compliance inside of machinery rooms, mechanical equipment rooms, chiller plants, cold storage facilities, and walk-in freezers by monitoring for refrigerant leaks for numerous gases including HFCs, HFOs, HCFCs, CO2, and ammonia (NH3)).

This product detects all CFC, HFC, and HCFC refrigerants as low as 0.006 oz/yr, including R-410a and R-507.

Refrigerant leaks in HVACR equipment – particularly commercial refrigeration systems -- are a significant problem.

Know what type of detector you are using, know how to use it, and ensure it’s capable of detecting leaks by calibrating it on a regular basis.

Hoshizaki America Inc. started shipping sushi cases with the energy efficient and environmentally friendly refrigerant, R600a, earlier this month.

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

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

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.

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.

The transition to A2Ls will likely serve as an interim solution. Europe has already embraced propane in certain heat pump systems, and the U.S. may follow suit, albeit with a different low-GWP refrigerant.

ALDI aims to become the most sustainable grocer in the U.S., by committing to transition to natural refrigerants in all stores by 2035.

In preparing for the refrigerant transition, contractors and distributors should review their inventory and become educated on the regulations.

With over 1,000 Sunday service attendees and many church activities throughout the week, energy efficiency for the sake of cost savings was critical.

Both commercial facilities and residential domiciles are taking advantage of heating and cooling technology at accelerated rates.

As HVACR technology advances, contractors often find themselves navigating new learning curves on a regular basis. VRF is no exception.

Contractors need to implement a refrigerant management strategy that accommodates both legacy and A2L systems, as well as emphasizes recovery and reclamation.

When changing the refrigerant within your pumping application, it is worth discussing the application with a process specialist.

EPA is counting on increased recovery and reclamation in order to maintain existing HVAC equipment, and finally, the numbers are going in the right direction.

In the seventh installment of this series, we ask if there are any special storage requirements for A2L refrigerants.

This e-book includes a summary of sustainable HVAC developments, in particular of heat pumps and refrigerant changes to address climate change.

Recording Venue: Lucene Revolution 2012 (Boston) Guest: Grant Ingersoll Grant Ingersoll, a committer on the Apache Solr and Lucene, talks with Robert about the  problems of full-text search and why applications are taking control of their own search, and then continues with a dive into the architecture of the Solr search engine. The architecture portion of the […]

Charles Anderson talks to Mitchell Hashimoto about the Vagrant open source project, which can be used to create and configure lightweight, reproducible, and portable development environments. Vagrant aims to make new developers on a project productive within minutes of joining the project instead of spending hours or days setting up the developer’s workstation. The outline […]

Grant Ingersoll, founder and CTO of LucidWorks, talks with Tobias Kaatz about his book Taming Text: How to Find, Organize, and Manipulate It. They begin by discussing popular existing systems for the automated understanding of contextual information. One such system, IBM Watson, drew attention for its victory in the “Jeopardy” game show. They proceed to […]

Donald Trump’s debunked claims tap into a centuries-long racist narrative that has real impact on Haitian immigrants and Haitian Americans, in Ohio and beyond.

No matter who wins the 2024 presidential race, immigrant rights advocates are laying the groundwork for long-term justice.

Jan. 1, 2025 sets a new requirement for global-warming-potential refrigerants in California.

In this episode of Ask Annissa, Annissa Coy responds to the following message: “My customer is asking me for a guarantee of my work and for the removal of odor. … I don’t know how to answer this.”
