Each component brings its own characteristics to the final mixture   Refrigerant blends are mixtures of refrigerants. These blends have been carefully formulated and mathematically modeled to tailor their characteristics to match certain properties of the refrigerants they are replacing and to provide maximum system efficiency and performance. In the past, refrigerant blends have been based on chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), and hydrofluorocarbon (HFC) refrigerants. However, because of ozone depletion potential (ODP) and global warming potential (GWP) regulations, most of today’s refrigerant blends are HFC-based and have zero ODP with small GWP impacts to the environment. Even though most of today’s blends are HFC-based, they can sometimes contain a small percentage of a hydrocarbon (HC) as a refrigerant. The HC, however, will not make the blend flammable because it only constitutes a small percentage (usu […]

If internal combustion was the monumental technological achievement that, over the decades, contributed to climate change, perhaps new technologies can help solve the crisis. The Paris climate talks are crucial not only for forging a political agreement to reduce carbon emissions, but for fostering a political environment that encourages green technology and innovation. U.S. Secretary of Energy Ernest Moniz, speaking in November at the Carnegie Endowment for International Peace, stressed that encouraging climate innovation was an essential component of success. “We are advancing the theme that energy technology innovation, and the resultant cost reductions in energy technology, are ultimately the key to meeting our climate challenges,” Moniz said. Innovation is not a silver bullet, however. “Neither better technology, nor changing to low-carbon behavior will be sufficient on its own; both will be necessary,” Gregory Nemet, a professor o […]

Plant for chiller and Organic Rankine Cycle refrigerant HFO1336mzz to begin production in 2017 in Changshu, China The Chemours Company and its partner Changshu 3F Zhonghao have broken ground on the world’s first full-scale production facility for HFO-1336mzz . This site, expected to begin production mid-year 2017, will provide increased capacity of low global warming potential (GWP) foam expansion agents and refrigerants. The primary initial use of the HFO will be as a foam expansion agents, but with a GWP of less than two, Chemours is developing it for refrigerant applications, thanks to its non-flammability, high efficiency and thermal stability. Chemours said it is actively developing several new refrigerant fluids based on HFO-1336mzz technology for a variety of applications, including traditional chiller systems and the emerging arena of waste heat recovery using technologies such as high temperature heat pumps and organic rankine […]

AHRI to provide progress report on pledge to invest $5 billion in research over the next 10 years for new refrigerants and HVACR equipment.   At a White House Industry Leader Roundtable today, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) will provide a progress report on its 2014 pledge to invest $5 billion in research over the next 10 years for new refrigerants and HVACR equipment to support energy efficiency. During the event, AHRI President and CEO Stephen Yurek reported that the industry spent more than $255 million in 2015 toward a 10-year, $5 billion commitment in research and development (R&D) and capital expenditures to develop and commercialize low-global warming potential (GWP) technologies, demonstrating the industry’s commitment to environmental stewardship. He noted that the $5 billion pledge is in addition to the nearly $2 billion that was spent on such research in the previous five years. The […]

A survey of over 100 ammonia refrigeration systems operating in food manufacturing facilities in the UK found that under 20% met legislation covering dangerous and explosive materials. The survey by consultant Stephen Gill Associates revealed that 30% of sites had either no risk assessment or inadequate ones for their ammonia refrigeration systems. Principal Stephen Gill said: “Unfortunately, lack of understanding of the requirements is no excuse for lack of action in the eyes of the HSE, and indeed the insurance companies.” The ATEX 137 Directive on explosive substances requires that all companies operating with areas, (including those containing ammonia refrigeration plant), classified as ‘Hazardous’ classify their production areas into zones and assess the risks both to their employees and their plant assets. While the majority of the sites in the survey had DSEAR (Dangerous Substances and Explosive Atmosphere Regulations) assessment […]

Speaking of ice, the first thing emerging from the mind is the little square ice, pure and transparent. In the summer, put two ice cubes in the beverage, beer, extremely cool. But during the party, people are often full of enthusiasm about chatting instead of drinking, and thus the ice melted, diluted into the beverage so that the taste is influenced. For businesses, the customer experience is essential. The quality of the ice determines the taste of drinks and ice cream, of course, also determines the attractiveness to buyers. Focusun, as the ice machine manufacturer, is the specialist of ice production, aims to solve this problem. We attempt to use orange juice and mulberry juice as inlet water and leads to bright and colorful ice with rich flavor In addition to make food tastes more delicious, the fruit juice ice has the greater advantage that you can conserve fresh juice longer. Low temperature makes longterm preservation of fresh j […]
