Cubic A2L and A3 Refrigerant Gas Leakage Sensing Solution in Commercial Air Conditioning
In the United States, hydrofluorocarbons (HFCs) are the mainstream refrigerants in commercial air conditioning industry. However, HFCs have high GWP and are gradually being eliminated from the refrigerant market. Therefore, it is imperative that HFCs must be gradually replaced. On May 30, 2023, EPA put a new rule named Protection of Stratospheric Ozone: Listing of Substitutes Under the ...

Foam Rubber Vs. Sponge Rubber: What is the Difference?
Foam rubber and sponge rubber are extremely flexible materials originating from standard rubber compounds. In terms of the qualities of cushioning, insulating, and sealing, they are quite important. In addition, they have great flexibility, compressibility, and the ability to absorb liquid. Consequently, they can offer an alternative for cushioning and adapting to surfaces that are not perfectly ...

VOC Risk Mitigated at Site of Former Chemical Manufacturer - Case Study
A long-vacant San Francisco Bay Area brownfield was once the site of a former chemical plant that produced chlorofluorocarbons, fuel additive anti-knock compounds, and titanium dioxide from 1956 to 1997. With onsite rail service and more than three million households within 50 miles, the property was considered a prime location for a new 2.2 million square foot logistics development. However, the ...

Froilabo F-Gas Regulations
EU F-Gas Regulations As global warming is at the heart of our concerns, the refrigerants used in all Froilabo freezers comply with the new F-Gas regulations (EU No. 517/2014). In order to drastically reduce the environmental impact of our freezers, Froilabo have introduced a ‘green gas’ version of our refrigeration equipment and will keep them operating for as long as possible. Global ...

Global Warming Potential, CO2 Equivalence and the Impacts of Fossil Fuel Combustion
A greenhouse gas (GHG), as defined by the Intergovernmental Panel on Climate Change (IPCC) is a compound which has the ability to trap heat over a certain lifetime in the atmosphere. The six main GHG gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). The impact of these GHG gases is quantified ...

FPI on the Day for Ozone Layer: Concise Solution Makes Big Progress
September 16th, World Ozone Day, is also known as the International Day for the Preservation of the Ozone Layer. The ozone layer is the second layer of the stratosphere, which is the mass of protective gases clinging to our planet. Protecting the ozone layer is for the good of every creature on the planet because of its great capability in trapping ultraviolet radiation (UV light), which may ...

What are Scope 1, 2, and 3 Greenhouse Gas Emissions?
A greenhouse gas (GHG) is a gaseous compound with the ability to trap heat (or longwave radiation) in the Earth’s atmosphere. This results in high temperatures being retained in the lower atmosphere, thus allowing less heat to escape back to space. Common GHGs present in the atmosphere include fluorinated gases (chlorofluorocarbons (CFCs) (e.g., tetrafluoromethane (CF4)) and ...

The Last Decade was the Hottest in 125,000 Years
The temperature of planet Earth is now 0.91°C (1.64°F) above the 20th century average of 12.9°C (55.2°F) and 0.8 degrees C (1.4 degrees F) higher in comparison to the first decade of the twentieth century. The past decade is declared as the hottest of the past two millennia with 2019 as the third hottest year on record as the temperature is accelerating worldwide. Every decade is ...

Introduction to New York refrigerant regulations
Interested in learning about the State of New York’s refrigerant regulations? This article provides an overview of the state’s various refrigerant regulations. Because in addition to the federal EPA regulations (e.g., Section 608) that govern refrigeration and air-conditioning systems in this state, New York has its own set of additional requirements at multiple levels. Such ...

Refrigerant Compliance in 2021: What to have on Your Radar
Do you know what should be on your radar for refrigerant compliance in 2021? Now that plans for an HFC phase down in the United States have solidified, one thing is clear for refrigerant compliance in 2021: Change. Very likely, refrigerant handling requirements for hydrofluorocarbons (HFCs) will evolve in the near-term at multiple regulatory levels. Thus, now is the time to review important ...

Data Centers - Free Air Cooling
Artificial Intelligence (AI), gaming, high-performance computing, 3D graphics, and the Internet of Things (IoT) all require faster and more complex computing power. The rapidly expanding cloud catering business, along with the growth of “edge computing,” and the competition between providers, is creating a need for more data center space, and demanding more computing cores per square ...

The Power of Pyrometers
The rapidly increasing global demand for food, which includes an increased emphasis on consumption of protein-rich diets, is supporting agricultural growth and therefore the demand for ammonia and fertilizers. Ammonia is also being increasingly chosen over hydroflurocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs) as a refrigerant, due to its cost-efficiency and heat transfer properties. This ...

Gases that cause the most air pollution
Air pollution is the presence of dangerous substances in the atmosphere in concentrations high enough and for durations long enough to cause harm or undesirable effects. Chemicals, dust, suspended particles and gases, among others, pollute the air we breathe every day. The emissions of gases can be caused by natural or human factors, but only the gases generated by human activities, such as ...

MonoExact DF150E - Selecting oxygen analysis for reflow furnace applications.
Maintenance of low oxygen concentration in reflow furnaces produces higher quality product, less product defect, and lower maintenance costs - potentially saving thousands of dollars per year. But only the advent of a unique non-depleting oxygen sensor by Servomex avoids problems with sensor contamination and depletion experienced by traditional sensing technologies. THE ROLE OF OXYGEN ANALYSIS ...

Major air pollutants and their sources
Air pollution is one of the most important environmental problems affecting people and the planet. The World Health Organization in its latest report warns that 1 in 9 people who breathe polluted air die from a respiratory disease. Cities and surrounding industrial areas are the ones that concentrate the highest degree of air pollution. Human and industrial actions emit a large amount of toxic ...

The Rationale for Accelerating Regionally Focused Climate Intervention Research
Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

PureAire Universal Gas Detector Offers Protection Against Toxic Levels of Ammonia
In March of 2016, an ammonia gas leak at a seafood processing plant in Boston left one worker dead. The fumes at the plant were so powerful that firefighters could not promptly enter the scene to mitigate the gas leak and try to save the staff member until much later. Reports show that 5,300 pounds of ammonia gas leaked out of the plant. If you work with ammonia at your facility, learn why this ...
