On 7 April, on the eve of China Refrigeration 2015, one of the largest trade shows in the HVAC&R industry shecco organised the first ever ATMOsphere Network Shanghai. Supported by Danfoss and Mitsubishi Heavy Industries (MHI), the event gathered over 60 experts from industry, research institutions and government, who gathered to discuss the latest natural refrigerant trends in the world’s largest HVAC&R market. The event also featured a preview of the upcoming bilingual English-Chi
Although in many applications natural refrigerants remained the ‘emerging technologies’ on display, leading companies like Mayekawa, CAREL, thermea. Energysystems and Itomic quickly turned their attentions to Korea to showcase their CO2 technology and share their success stories with R744.com.
Kaori’s entrance to the Chinese commercial heat pump market in 2015 was a welcome one. With the revised China Environmental Protection Law to take effect in 2015, the company is intent on meeting the increasing demands for CO2 heat pumps.
R744 innovations from Japan Part 2: integrated systems and improving CO2 system efficiency in warm climates
In part 2 of our reporting on the CO2 technology innovations discussed at ATMOsphere Asia 2015 we focus on the presentations from Carel, Bitzer, and Danfoss on integrated CO2 systems and technologies to increase the energy efficiency of CO2 in warm climates. These include more traditional systems such as mechanical subcooling and newer ones such as parallel compression and ejectors.
In part two of our reporting from the 49th Supermarket Tradeshow (SMTS), which took place from 10-12 February 2015 in Tokyo, Japan, R744.com reports on the first rack-type CO2 transcritical booster system installation, a collaborative project between Japanese showcase manufacturer Fukushima Industries and system manufacturer Nihon Netsugen Systems.
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.
