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.
Trends and experiences with climate-friendly natural refrigeration technology outside the United States
On Thursday 19 February 2015, Green Chill organised a webinar on natural refrigerants led by Nina Masson, Deputy Managing Director of market development company shecco. In addition to providing information on select companies’ use of certain refrigeration system types, Masson provided an update on refrigeration technology trends in different countries and regions, saying that there could be up to 64,000 CO2 transcritical stores in Europe by 2025, and over 750 in Japan.&nbs
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.
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.
Adding to the growing knowledge base on ejectors in CO2 transcritical refrigeration systems, research presented by SINTEF at the Gustav Lorentzen 2014 conference (GL 2014) shows that a CO2 ejector refrigeration system with parallel compression can achieve around 25% energy savings compared to a standard R404A system in warm climates. SINTEF also analysed an integrated energy system with CO2 refrigeration installed in Norway, demonstrating a 30% reduction in energy
DTI at Gustav Lorentzen 2014: can ice storage and Vortex Flow Sensors improve CO2 system efficiency?
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
