Countdown Ferrymead reopens http://www.r744.com/news/view/5130 http://www.r744.com/news/view/5130 2014-04-11 11:02:20 article 10 April 2014: Countdown Ferrymead will reopen its doors today after it sustained extensive damage in the 2011 earthquake, and had to be subsequently closed and demolished.<br /> <br /> The store, which will be officially opened by Deputy Mayor Vicki Buck, is providing 150 jobs for the community including 112 new faces to the Countdown team.<br /> <br /> New features of the store<br /> <br /> At 4,200 square metres, the new store returns with a larger, more modern shopping experience, providing a wider range of products and services,<br /> <br /> Behind the scenes, the store will also feature a range of environmental initiatives including a CO<sub>2</sub> refrigeration plant system that will give significant energy efficiency benefits. Night blinds on refrigerated cabinets, sliding covers on freezers and energy efficient lighting among other things will also help minimise the store&rsquo;s carbon footprint.&nbsp; India&rsquo;s first water source CO2 electric heat pump (EHP) system installation at milk plant http://www.r744.com/news/view/5124 http://www.r744.com/news/view/5124 2014-04-10 10:41:48 article The first Mayekawa unimo W/W water source electric heat pump (EHP) has been installed at India&rsquo;s second biggest milk, Verka Food Products.

In addition, the ICA will promote &ldquo;all copper&rdquo; coils as a means of improving the energy efficiency by inhibiting the grown of microorganisms on heat exchanger coils.&nbsp;</div> <div>&nbsp;</div> <div>The ICA exhibit this year will be in Booth W1B45. It&rsquo;s the fourth consecutive year that ICA will promote MicroGroove technology at the China Refrigeration Expo. &nbsp;MicroGroove got its start in China when major Chinese OEMs began using smaller-diameter tubes for residential air conditioning applications, including window air-conditioners. These products are now widely available in the global marketplace. OEMS continue to advance the technology, employing MicroGroove tubes in heat pumps as well as refrigeration equipment; and using eco-friendly refrigerants in these systems.</div> <div>&nbsp;</div> <div>The ICA exhibit will be divided into two sections, highlighting the following technologies: 1) MicroGroove in refrigeration equipment and residential AC products, and 2) the superior long-term performance of antimicrobial &ldquo;all copper&rdquo; coils. &nbsp;Each of these application areas will be promoted under the ICA banner at the China Refrigeration Exposition this year in Beijing, emphasizing the many areas of market penetration for copper tubes.</div> <div>&nbsp;</div> <div><b>Antimicrobial Properties</b></div> <div><br /> Coils made with copper fins and copper tubes offer extraordinary antimicrobial properties. These &ldquo;all copper&rdquo; coils prevent various bacteria and fungi from multiplying on coils, thereby inhibiting the buildup of biofilms. Coils stay cleaner for longer periods of time and consequently high levels of heat-transfer efficiency can be maintained for longer periods of time.&nbsp;</div> <div>&nbsp;</div> <div><b>The MicroGroove Advantage</b><br /> &nbsp;</div> <div>ICA continues to sponsor research on refrigeration equipment and air-conditioners at leading universities in China through an industry consortium. Technical papers coauthored by ICA technical staff will be presented at several international conferences this year. These researchers will be on hand at the ICA Booth W1B45 of the China Refrigeration Expo to answer any questions you may have about MicroGroove technology or antimicrobial copper coils. Additionally, new software developed for simulating the performance of coils in refrigeration equipment is now available from suppliers of MicroGroove tubes.</div> <div>&nbsp;</div> <div>&quot;China continues to pave the way in advancing the use of copper in HVACR applications,&rdquo; said Nigel Cotton, MicroGroove Team Leader for ICA. &quot;These advances are driven by fundamentals, including the capability of making smaller-diameter tubes from copper and copper&rsquo;s inherent antimicrobial properties.&quot;</div> <div>&nbsp;</div> <div>&ldquo;Manufacturers want to use less material and MicroGroove allows them to do so,&rdquo; says Wenson Zheng, Deputy Director of Technology for ICA. &nbsp;&ldquo;The consumer benefits from lighter, smaller products that often exceed the performance of comparable products made from larger-diameter tubes. In turn, manufacturers benefit from the reduced material costs and increased performance, while utilizing familiar manufacturing production lines and equipment for copper.&rdquo;</div> Wieland K65 tube system for high-pressure applications http://www.r744.com/news/view/5121 http://www.r744.com/news/view/5121 2014-04-09 17:30:27 article The new K65 tube system from Wieland, made of the high-strength copper alloy, is ideal for high-pressure pipeline systems in CO<sub>2</sub> refrigeration applications. Now available in an additional size, 53,97 x 3,55 mm, the lightweight K65 can reduce the cost of refrigeration systems with operating pressures up to 120 bar. The tubes are also 40% lighter than copper tubes. The K65 system is the only T&Uuml;V certified copper based tube and fitting system available on the market. 7th European Heat Pump Forum http://www.r744.com/events/view/643 http://www.r744.com/events/view/643 2014-04-09 00:00:00 event <div>The 7th edition of the EHPA European Heat Pump Forum will take place in Berlin (at Ellington Hotel) on the 20th of May 2014.

Citing recent data from the World Health Organization (WHO) showing that approximately 7 million people die each year because of indoor and outdoor air pollution, the Coalition also agreed to launch a worldwide campaign to raise awareness of the health effects of air pollution and to prompt action to mitigate its effects. The Coalition approved funding of approximately $10 million for activities to improve climate and agriculture, as well as health, through reduction of short-lived climate pollutants. These range from efforts to reduce methane emission from paddy rice production, to HFC replacement technology demonstration projects, to the inauguration of a global strategy for ports and maritime vessels and raised clean fuel and vehicle standards in Western and Southern Africa. Three demonstration projects were approved by the CCAC to test technologies of climate-friendly alternatives that can become commercially viable in refrigeration and air-conditioning in Chile, Jordan and India.
