According the several presenters the end of the so-called &ldquo;CO<sub>2</sub> equator&rdquo; is in sight. <span style="color: rgb(255, 0, 0);">+</span> <span style="color: rgb(255, 0, 0);">VIDEO</span> CO2 refrigeration training: how supply is not keeping pace with demand&nbsp;&nbsp; http://www.r744.com/news/view/6262 http://www.r744.com/news/view/6262 2015-03-31 17:22:04 article In view of growing ecological awareness and the EU F-Gas Regulation, CO<sub>2</sub> is becoming a mainstream refrigerant in Europe, increasingly used in both domestic and industrial applications. However, the lack of training with regard to its installation and maintenance is slowing down its market uptake. Training needs to comprise both theoretical and practical approaches to learning to complement the heightened use, as the French Institute for Energy Training (Institut Francais de Formation en Energetique &ndash; IFFEN) explains.&nbsp; Advanced R744 heat pump solutions for the European market http://www.r744.com/news/view/6260 http://www.r744.com/news/view/6260 2015-03-31 16:27:47 article ATMOsphere Europe 2015 provided a platform for the latest heat pump innovations including ENEA&rsquo;s joint case study on a heat pump with a unique two-cylinder compressor, designed to cater for the European market. boostHEAT showcased its integrated heat pump/boiler solution while Mitsubishi Heavy Industries (MHI) and Sanden outlined the increased migration of their products from Asia to Europe. Heat exchanger design software CoilDesigner now encompasses variations in inside-tube surface enhancements, says the International Copper Association http://www.r744.com/news/view/6257 http://www.r744.com/news/view/6257 2015-03-31 10:35:21 article The International Copper Association announced today that simulations of the inner-grooves of MicroGroove copper tubes can now be accomplished using CoilDesigner, a proprietary heat exchanger simulation and design optimisation tool developed by the University of Maryland. Thanks to new developments by the ICA and Burr Oak Tool, Inc. (BOTI), and implemented by Optimized Thermal Systems, Inc. (OTS) into the CoilDesigner&nbsp;software, the effects of specific types of surface enhancements now can be simulated.<br /> <br /> The collaboration with BOTI addresses manufacturing challenges relating to the internal surfaces of the copper tubes, including MicroGroove tubes. Specifically, BOTI is developing non-mechanical expansion technology to expand MicroGroove tubes without deforming internal tube enhancements. This new expansion technology offers the opportunity to create complex and relatively fragile geometries. With this new software methodology in place, the effects of enhancements can be explored, to identify new geometries that increase heat transfer performance.<br /> <br /> According to recent studies by ICA, OTS and BOTI, microfins could increase refrigerant-side heat transfer coefficients as much as 300 percent, depending on the tube diameter. For a heat exchanger made with 5-mm MicroGroove tubes, the use of a microfin tubes rather than a smooth tubes could increase the heat capacity by more than 20 percent; alternatively, it could reduce fin material mass and tube material mass up to 10 percent and up to 17 percent, respectively. Additional work is ongoing to further investigate MicroGroove behavior and potential.

UPDATE:&nbsp;DeCO2ded: Understanding ROI on CO2 refrigeration systems http://www.r744.com/news/view/6241 http://www.r744.com/news/view/6241 2015-03-24 18:09:06 article As retailers seek to enhance their commitment to sustainability, a concern often raised is cost. Although replacing a traditional HFC based system with a 100% CO<sub>2</sub> system is more environmentally friendly, the initial cost for CO<sub>2</sub> refrigeration equipment is generally higher. However, as system manufacturer Hillphoenix explains in their White Paper &ldquo;DeCO<sub>2</sub>ded: understanding ROI on CO<sub>2</sub> refrigeration systems&rdquo;, CO<sub>2</sub> offers a positive return on investment (ROI) over time and &ldquo;an immediate dollars-and-cents calculation is neither strategic nor sufficient.&rdquo; ATMOsphere Europe 2015 highlights the need for further cooperation on the road towards a global phase down of HFCs http://www.r744.com/news/view/6240 http://www.r744.com/news/view/6240 2015-03-24 14:54:39 article ATMOsphere Europe 2015 provided a platform for key stakeholders from Europe, North America and Japan to discuss the road to a global phase-down of HFCs. Whilst Europe&rsquo;s leading role was clearly indicated - particularly since the enactment of the EU F-Gas Regulation in January 2015 - what particularly came to the fore was the need for a more balanced debate &ndash; both between developed and developing countries, and the many industries involved in the discussions. <span style="color: rgb(255, 0, 0);">+ VIDEO</span> Z-SC1 Biomedical Corp. http://www.r744.com/companies/view/z-sci1 http://www.r744.com/companies/view/z-sci1 2015-03-24 00:00:00 company Z-SC1 Biomedical Corp. is a Canadian-based company with a successful record of developing laboratory equipment for the biomedical and biotech industry.<br /> <br /> Headquartered in Montreal, Canada, with manufacturing bases in Seoul, South Korea, Z-SC1 Biomedical is revolutionising the scientific community.&nbsp;The Twincore freezer is the first and only of its kind, featuring two independent compressor systems each capable of maintaining -82C.&nbsp;<br /> <br /> Standard ultra-low temp freezers rely on a cascade refrigeration system.
