Is CO2 the Answer? http://www.r744.com/news/view/6178 http://www.r744.com/news/view/6178 2015-03-03 11:55:15 article <div>The most exciting and at the same time, challenging technological development in commercial refrigeration has been the growing popularity of carbon dioxide (CO<sub>2</sub>) as an alternative refrigerant. But challenges exist.</div> <div>&nbsp;</div> <div>With a non-existent &ldquo;global warming potential,&rdquo; CO<sub>2</sub> is seen as the gas that will eventually eliminate the use of man-made refrigerants. A total industry elimination of gasses such as R-410A, R-404 and others, is still a few miles down the road, but if the Environmental Protection Agency has its way, wholesale use of CO<sub>2</sub> will become a reality ASAP. But what will this change mean to contractors, supermarket managers, and systems manufacturers? What are the key technical challenges posed by CO<sub>2</sub>? &nbsp;</div> CO2&nbsp;gets some love at The NAFEM Show http://www.r744.com/news/view/6173 http://www.r744.com/news/view/6173 2015-03-02 11:37:22 article While hydrocarbons dominated natural refrigerant news at The NAFEM Show last week, a handful of exhibitors featured or discussed plans for carbon dioxide systems in North America. <span style="color: rgb(255, 0, 0);">+PHOTOS</span> 49th Supermarket Tradeshow: first rack-type CO2 booster system installed by Japanese retailer http://www.r744.com/news/view/6171 http://www.r744.com/news/view/6171 2015-02-27 12:36:10 article In part two of our reporting from the 49<sup>th</sup> Supermarket Tradeshow (SMTS), which took place from 10-12 February 2015 in Tokyo, Japan, R744.com reports on the first rack-type CO<sub>2</sub> transcritical booster system installation, a collaborative project between Japanese showcase manufacturer Fukushima Industries and &nbsp;system manufacturer Nihon Netsugen Systems. ITOMIC ECO-cute system with BITZER 4HTC reciprocating CO2 compressors http://www.r744.com/news/view/6168 http://www.r744.com/news/view/6168 2015-02-27 10:15:56 article The heat pump specialist ITOMIC is presenting its ECO-cute system at the conference ATMOsphere Asia &ndash; &ldquo;Natural Refrigerants &ndash; Solutions for Asia&rdquo; in Tokyo. This is a particularly powerful system that also protects the environment as, inside it, the pace is set by a BITZER 4HTC reciprocating compressor for CO<sub>2 </sub>applications. Following the very successful event in 2014, the organizer, shecco, is now preparing a second conference, and BITZER is once again participating as a Silver Sponsor.<br /> <br /> On February 5, 2015, visitors who have registered for the ITOMIC tour at the ATMOsphere Asia trade fair in Tokyo can expect a real highlight. ITOMIC will be demonstrating a fully functional installation of its highly efficient ECO-cute heat pump, which can supply 350 one-person households with warm water. This is a system with two hot water tanks, each with a capacity of 8,000 liters and a BITZER 4HTC reciprocating compressor. There are also two recirculation tanks integrated into the system, each holding 800 liters. Each day, the installation supplies enough hot water for 300 showers or enough to prepare 600 hot meals in a canteen.<br /> <br /> <b>Environmentally friendly and efficient<br /> </b><br /> One special feature is that ECO-cute uses the natural refrigerant CO<sub>2</sub> (R744), which has a very low global warming potential. Improvements over the previous models mean that the heat pump needs 55% less space and weighs 20% less while still offering better performance values. The ECO-cute produces four times as much usable heat as the electrical energy needed for its operation. Thanks to the high system efficiency, the ECO-cute lowers operating costs and protects the environment at the same time. That is clearly appreciated: ITOMIC has already sold about 1,000 systems domestically and abroad. Among other places, the heat pumps are used in factories, public buildings, schools and hotels.<br /> <br /> <b>Flexible for CO<sub>2 </sub>applications<br /> </b><br /> The semi-hermetic 4HTC reciprocating compressor from BITZER makes it possible. This 4-cylinder unit was designed for a trans-critical CO<sub>2 </sub>applications and for operation with a frequency inverter. Performance can be flexibly controlled so that the system&rsquo;s efficiency is always optimal. The 4HTC system&rsquo;s major strength is its energy efficiency. This is ensured by a suction gas-cooled motor, which is especially suited for speed control, and by the special drive gear geometry and the cylinder heads with their separate, thermally insulated, high and low pressure chambers. The quality is well proven, as BITZER has decades of experience in the manufacture of transcritical CO<sub>2</sub> compressors. The 4HTC has been successfully used around the world for more than ten years now. Its standard speed is designed for a large application range of between 30 and 70 Hz. 4HTC reciprocating compressors are also incredibly flexible as they can not only be used for trans-critical but also for subcritical cycles.<br /> <br /> <blockquote> <div>For us, environmental protection and system efficiency go hand in hand,&rdquo; said Ferdinand Spannan, Managing Director of BITZER Japan K.K. &ldquo;That&rsquo;s because we know that environmental pollution can only be permanently reduced with high-quality technical solutions. This is why BITZER has relied for decades on compressors for natural refrigerants. With our extensivae product portfolio, we can offer the best compressor for all heat pump applications.&rdquo;</div> </blockquote> Heat Pumps Continue Northern Migration http://www.r744.com/news/view/6152 http://www.r744.com/news/view/6152 2015-02-25 11:55:40 article Traditionally, heat pumps were thought of as products only for North America&rsquo;s Sunbelt. However, heat pump technology has drastically evolved over the past several years with higher heating efficiencies and strong performance at temperatures well below freezing. This growth is making these units more attractive in the Northern states, and the industry is pumping them up with new technologies and features.
