A CO2 transcritical booster system is helping to deliver energy savings at a Co-op supermarket in the northern English town of Horwich, near Manchester.
According to the first EU-level Strategy on Heating and Cooling, the phase-down of fluorinated gases under the EU F-Gas Regulation will help accelerate the renovation of heating and cooling systems in buildings. The European Commission identifies natural refrigerants as having great energy-saving potential.
Heat pumps, heat recovery systems and ammonia in industrial use – these will be the most interesting applications to focus on the refrigerant market this year, Jesper Olsen, Alfa Laval’s business and application manager, told R744.com. The Swedish company is heading into 2016 with ambitious plans to expand its ammonia and CO2 portfolio.
Sanden plans to launch a residential CO2 heat-pump water heater in the US by early second quarter of 2016, and prominently featured the product at its AHR Expo booth last week.
CoilDesigner’s latest upgrades incorporate small-diameter MicroGroove tubing, which supports CO2 and hydrocarbon systems.
In a Sprouts store in Georgia, an all-CO2 system is performing more efficiently than baseline HFC technology. As Accelerate America Editor Michael Garry found out in the July-August edition, the U.S.’s increasingly positive stance on natural refrigerants – and CO2 in particular – is, for the first time in the U.S., taking effect in warm ambient temperatures.
Although in its infancy, the adoption of CO2 systems in the world’s largest industrial economy, China, continues to gain traction. While HFCs and HCFCs still permeate the market in China, in order to mitigate the effects of climate change it’s only a matter of time before sustainable natural refrigerants like CO2 attain widespread implementation.
As in previous years ATMOsphere America 2015, organised in Atlanta on 25-26 June, provided an opportunity to learn about the very latest technology developments. A series of technology case study sessions focused on industrial refrigeration, heat pumps, and new applications provided no shortage of evidence on the advantages of CO2 in applications beyond the world of commercial refrigeration.
