CO2 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 CO2 vending machine.

Natural refrigerants MAC systems could reduce GHG emissions by 30% in China

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.
