Hiber reaping CO2 transcritical dividends http://www.r744.com/news/view/6762 http://www.r744.com/news/view/6762 2015-11-25 10:54:39 article At Supermercados Hiber, energy efficiency and environment are key players in the company&rsquo;s decisions. In 2012, Hiber had the first store in Spain using only CO<sub>2</sub> as refrigerant and in 2014 made history with the first Spanish urban CO<sub>2</sub> transcritical store.<br /> Sanden CO2 heat pump water heater named as top products for 2016 http://www.r744.com/news/view/6761 http://www.r744.com/news/view/6761 2015-11-25 10:49:00 article Standard heat pumps use hydrofluorocarbon (HFC) refrigerants such as R410a, which has a 100-year global warming potential (GWP) greater than 1,700. Though they work well, these refrigerants also typically do not create water temperatures high enough for hydronic heating. <br /><br />Sanden is now offering a residential heat-pump water heater that uses CO<sub>2</sub> (GWP of 1) as the refrigerant and can deliver water hot enough for domestic hot water, and even for hydronic heating in energy-efficient homes.<br /><br />Available in Japan for several years, Sanden&rsquo;s CO<sub>2</sub>-based heat pump is coming to the U.S. in 2016. Using low-GWP CO<sub>2</sub> as a refrigerant, this 4.5 kW model produces high-temperature water with very efficient heat transfer, very little pump energy, and good cold-weather performance. It is capable of delivering approximately 16,000 Btu/hr and can produce 149&deg;F water with outdoor temperatures as low as &ndash;15&deg;F.<br /><br />Compared with other heat pump water heaters, the Sanden water heater is a split system, so it doesn&rsquo;t lower the air temperature in the space where it is located.<br /><br />The outdoor unit is paired with storage tanks of different sizes for different applications, including an 80-gallon stainless steel tank that can supply domestic hot water, and even space heating in efficient homes (a larger 11 kW version better-suited for space heating is in the works). Because of the significantly higher operating pressure of CO<sub>2</sub> refrigerant (compared with HFCs), the piping and connections with this product must be more rugged than that used for standard heat pump water heaters. UPDATE: What future lies for the Spanish F-gas tax? http://www.r744.com/news/view/6748 http://www.r744.com/news/view/6748 2015-11-20 14:40:00 article Spain&rsquo;s senate has endorsed an amendment to the 2016 General State Budget Bill approving the extension of reduced tax level on fluorinated gases in 2016. As a result, the tax level will remain the same as in 2015 for another year: 66% rather than the 100% originally planned. Industry to challenge Defra on DIY use of R134a refrigerant in MAC http://www.r744.com/news/view/6754 http://www.r744.com/news/view/6754 2015-11-19 12:30:00 article European trade body MACpartners says its is &lsquo;gravely concerned&rsquo; at the apparent about turn for DIY R134a top-ups in the UK, which it says directly contradicts the EU MAC Directive.<br /><br />MACpartners has vowed to challenge the "astounding" decision to allow the&nbsp;purchase of f-gases by unlicensed individuals and the general public, and says it will be appealing to both Defra and the European Commission over the matter.<br /><br />Worryingly, MACpartners believes the U-Turn was made only after several undisclosed UK stakeholders questioned the authority of Defra to restrict the sale of these products, stating that it is against the "best interests" of the professional auto repair industry, while also contravening the MAC Directive to phase down HFCs, not promote their broader use.<br /><br />Broadly, the use of the gas for filling MAC systems (HFC R134a) is not permitted for newly type-approved vehicles sold in the EU since January 2011 (pushed back to 2013), and all new vehicles sold from January 2017. Instead, the impacted vehicles must use a refrigerant gas with Global Warming Potential (GWP) of 150 or less such as natural refrigerant R744. Paris steps up security for United Nations climate conference COP21 http://www.r744.com/news/view/6753 http://www.r744.com/news/view/6753 2015-11-19 12:10:00 article In less than two weeks the United Nations climate change conference viewed by many as the most important global environmental summit in years will welcome the world&rsquo;s most powerful leaders and heads of state, including U.S. President Barack Obama.<br /><br /> <div>The conference will run for nearly two weeks, starting 30 November, on the northern edge of Paris at Le Bourget, in a city still reeling from last week's atrocities where 129 people were killed and many more wounded by a series of concurrent terrorist attacks.<br /><br />With concern heightened about France&rsquo;s ability to ensure anyone&rsquo;s safety, officials have announced that 115,000 police officers, gendarmes and soldiers will be deployed across the country. Thousands of troops have descended on the capital; men in combat fatigues, toting automatic weapons, are a common sight at train stations, bustling squares and landmarks such as the Eiffel Tower.<br /><br />More than 100 heads of state and government, including Obama, have accepted invitations to attend the opening days of the conference. French Prime Minister Manuel Valls said that no world leader had requested postponement of the summit, an event he called &ldquo;crucial to the planet&rsquo;s future.&rdquo;</div> Sanden Set to Expand&nbsp;CO2 Compressor Market http://www.r744.com/news/view/6751 http://www.r744.com/news/view/6751 2015-11-19 11:01:00 article The Japanese compressor maker behind Coca-Cola&rsquo;s global conversion to CO<sub>2</sub> vending machines and coolers, Sanden is gearing up production in China to support other end users of the natural refrigerant Nestl&eacute; executive: &lsquo;We are all facing risks of having supply challenges&rsquo; http://www.r744.com/news/view/6750 http://www.r744.com/news/view/6750 2015-11-18 16:25:00 article Climate change is confronting the European food sector with an unprecedented risk related to supplies of agricultural raw materials, warns Pascal Gr&eacute;verath.<br /><br />Pascal Gr&eacute;verath is Head of Environmental Sustainability at Nestl&eacute;. He also chairs the environmental sustainability committee of FoodDrinkEurope, an industry trade group. He spoke to EurActiv&rsquo;s publisher and editor, Fr&eacute;d&eacute;ric Simon.<br /><br />An important element is the use of natural refrigerants. There is a commitment through the consumer goods forum, which is a global organisation involving many food companies and retailers, to use natural refrigerants instead of HFCs ― whether ammonia, CO<sub>2</sub> or hydrocarbons. And so there is a commitment from this forum to phase out HFCs, which have a significant global warming potential.

As one of the partners of the COP21, Carrefour is seeking to find ways of helping to curb climate change, with it's goal to use only CO<sub>2</sub> refrigeration equipment in line with its target of reducing its CO<sub>2</sub> emissions by 70% between now and 2050.</div> Cold fact is that transporting food can become less harmful with CO2 http://www.r744.com/news/view/6744 http://www.r744.com/news/view/6744 2015-11-16 10:24:01 article In &ldquo;Food Foolish,&rdquo; authors and cold chain industry veterans John Mandyck and Eric Schultz connect the dots between cold chain technologies, food waste, world hunger and greenhouse gas emissions. <div>&nbsp;</div> <div>Greening the chain means making its underlying technologies more energy efficient both mechanically and via computerised monitoring systems; and using refrigerants other than hydrofluorocarbons (HFCs) to make things cold, said Mandyck, chief sustainability officer with United Technologies and Industrial Systems.</div> <div>&nbsp;</div> <div>One of United Technologies&rsquo; subsidiaries, Carrier, is a major manufacturer of heating, air-conditioning and refrigeration systems. Its alternative refrigerant of choice is CO<sub>2</sub>, which has a global warming potential that is 2,000 to 4,000 times lower than conventional HFC refrigerants, Mandyck said.</div> <div>&nbsp;</div> <div>With these changes, the cold chain could expand into developing nations to help solve logistical issues associated with alleviating hunger, and do so without raising the chain&rsquo;s overall carbon footprint, Mandyck explained. But you must factor in how cold chain technology can take a bite out of the soaring food waste tally.</div> 2016 HVAC&amp;R Trade Exhibition &amp; International Industry Conference&nbsp; http://www.r744.com/events/view/920 http://www.r744.com/events/view/920 2015-11-16 00:00:00 event This year we combine our efforts with the International Institute of Refrigeration to bring you a prestigious event that attracts researchers and industrialists, providing an opportunity to showcase cutting edge developments in sustainability, retail refrigeration and the cold chain.&nbsp; ATMO Australia debuts in Melbourne, ATMO America moves to Chicago http://www.r744.com/news/view/6742 http://www.r744.com/news/view/6742 2015-11-12 15:08:45 article The ATMO events are not only growing in stature but also conquering new territory.
