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 the July/August edition of Accelerate America, Eduardo Navarro de Andrade of Hillphoenix discusses how they are attracting new end users in North America to the OEM’s all-CO2 refrigeration 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.
Enex has been actively developing solutions to increase CO2 system efficiency in warm ambient climates like Spain and Italy. Using parallel compression and ejectors in unison, the company has realised significant efficiency gains and cost (first cost + energy cost) reductions. With more than 60 units installed with auxiliary compressors and more than 20 units using ejectors, the company’s accumulated data proves the energy savings of Enjector® technology can be as
The continually diminishing CO2 efficiency equator was a hot topic at ATMOsphere Europe 2015. Several system manufacturers presented the methods by which CO2 transcritical system efficiency can be improved, with ejector technology taking the spotlight. According the several presenters the end of the so-called “CO2 equator” is in sight. + VIDEO
