For its second year, ATMOsphere Asia 2015 returned to Tokyo, to the prestigious Shin-Maru Conference Square. Organised from 3-5 February, the event, with the tagline “Natural Refrigerants – Solutions for Asia” gathered 160 participants and 33 international presentations. Lawson, SAVE ON, The Coca Cola Company, Panasonic, Sanden and Carel, among others, confirmed that leading Japanese end users and system suppliers are investing heavily in CO2 technology, with over 75

Designed to bring key stakeholders together to support the adoption of natural refrigerants in Japan and beyond, ATMOsphere Asia 2015 provided policy-makers, end users, and HVAC&R component and system suppliers with an important platform to discuss the latest market, policy and technology developments for CO2. With a projected 24% increase in government subsidies for natural refrigerants in 2015 and green procurement policies set for the Tokyo 2020 Olympics, a dynamic market environment has been created for natural working fluids in Japan. What is more, technological improvements making CO2 systems lighter, more compact, and more efficient in extreme climates can only help to accelerate market uptake.

Pascal Air: environmentally friendly ultra low temperature storageMayekawa 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. 

R744 innovations from Japan Part 3: CO2 heat pumps and peak shift technologies
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 CO2vending machine. 

R744 innovations from Japan Part 2: integrated systems and improving CO2 system efficient in warm climates: In part 2 of our reporting on the COtechnology innovations discussed at ATMOsphere Asia 2015 we focus on the presentations from Carel, Bitzer, and Danfoss on integrated COsystems 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.

R744 innovations from Japan Part 1: pressure adjusted control and multiple compressors improve system efficiency: At ATMOsphere Asia 2015, presentations during the Commercial Refrigeration Technology Case Studies session by Panasonic and Sanden showcased the unique features and benefits of their respective CO2systems for convenience stores (CVS). Whether it is Panasonic’s new “pressure adjust control” system or Sanden’s system with three compressors in cascade, each is smaller, lighter and cheaper than comparable conventional models.
ATMOsphere Asia 2015: next five years to see R744 take centre stage in commercial and industrial refrigeration around the world: During the 2nd edition of ATMOsphere Asia, it became apparent that due to a combination of industry awareness and expected global regulations restricting the use of HFCs; that R744 is primed to take centre stage globally. This drive to adopt R744 is becoming more evident with higher aspirations from Japanese firms and the government, and could help to green the 2020 Olympics in Japan.

ATMOsphere Asia 2015 highlights Japan’s leading role in promoting natural refrigerants: ATMOsphere Asia 2015 – “Natural Refrigerants – Solutions for Asia” started off with an encouraging policy update from Japan. Focusing on both domestic and international dimensions, an overview was provided on national incentives and measures designed to promote natural refrigerants. Speakers noted rapid developments with regards to the Japanese government’s response to reducing f-gas emissions, which includes providing €46.5 million to incentivise natural refrigerants, and developing a labelling scheme that aims to raise awareness of the environmental impact of refrigerants.
