The 49th Supermarket Tradeshow (SMTS), which took place from 10-12 February 2015 in Tokyo, Japan, brought together some of the most innovative companies, institutions and products in supermarket refrigeration. R744.com reporters were on the scene to bring you exclusive interviews from Panasonic, Bitzer Japan and its partner, Shibata Welding Construction, Co.
Beijing Topnew Info & Tech Co., Ltd has introduced Carrier’s DataCO2MPLETE™ distributed cooling systems, using CO2 as refrigerant, in two large data centres in Beijing. With customised design for heat dissipation in the high-heat and high-density data centres, the system achieves energy savings of approximately 25 percent compared to conventional systems and reduces the cost of initial investment and maintenance with higher equipment reliability.
Mayekawa and Sea Sky Global presented the benefits and experiences in ultra low temperature storage thanks to the Pascal Air, which uses air as the working fluid, at ATMOsphere Asia 2015 in Tokyo.
ATMOsphere Asia 2015 unearthed plenty of positives for CO2 heat pump applications as Mitsubishi Heavy Industries explained the field test results for its Q-ton, the world’s first two-stage compressor for commercial use. Meanwhile, Yamato and The Coca-Cola Company demonstrated the benefits of their respective peak shift technologies, the Ultra-Eco-Ice thermal storage CO2/brine refrigeration system, and an award-winning CO2 vending machine.
At the 11th Gustav Lorentzen Conference on Natural Refrigerants, Johanna Gloël of GIZ Proklima presented on the potential for China to reduce greenhouse gas (GHG) emissions through the use of natural refrigerants, which would replace fluorinated gases in car air conditioning systems. The research suggests that GHG emissions in China could be reduced by 30% by 2030.
Italian-based Castel is a leading global manufacturer of components for refrigeration and air conditioning systems, serving more than 75 countries. Recently announcing its Silver Partnership with R744.com, Castel will soon showcase a new series of Ball Valves, for installation in commercial and industrial refrigeration systems, as well as heat pumps, on R744.com. See preview below.
The Danish Technological Institute (DTI) presented two papers on topics related to CO2 refrigeration systems at the 2014 Gustav Lorentzen Conference on Natural Refrigerants held in China from 31 August – 2 September. In the first presentation, ice storage for a transcritical refrigeration system is suggested in order to achieve greater energy savings in warmer climates, and flexible power consumption.
A wealth of new research and technological developments on CO2 as a refrigerant in centralised commercial refrigeration, heat pumps, glass door merchandisers and data centre cooling was presented at the 11th biennial Gustav Lorentzen conference on natural refrigerants. The event provided valuable insight into current and upcoming technology trends for all alternative refrigerants. Whilst CO2 stole the show, R744 research continues to focus on improving
Efficient CO2 refrigerant solutions for warm ambient temperatures was a key topic of discussion at the Gustav Lorentzen 2014 (GL 2014) Conference on Natural refrigerants, which took place from 31 August to 2 September 2014 in Hangzhou, China. R744.com, a silver sponsor of GL 2014 together with market development company shecco, reports on the latest technological developments and research into expanding the use of CO2 transcritical to southern climates, which represent a si
