Htm3R744—the new name of carbon dioxide refrigerant. Compared with ordinary refrigerants, carbon dioxide refrigerants are more energy-saving, more environmentally friendly, and will not produce greenhouse gases. They are expected to be promoted and used in data center refrigeration systems in the future.
USC refrigeration expert M&M Carnot said data centers should use carbon dioxide refrigeration technology to reduce the impact on the environment.
US-Canadian cooling specialist M&M Carnot says data centers should move to cooling their data centers with CO2, to reduce their environmental impact.
The company said that the global warming potential of carbon dioxide is much lower than that of traditional refrigerants, which are now Global phase-out. According to a guide released this month, carbon dioxide can be used in the same type of refrigeration system, effectively refrigerating through similar expansion and compression cycle processes.
The company says CO2 has a much lower global warming potential than traditional refrigerators, which are being phased out around the world. CO2 can be used in the same sort of chillers, going through a similar expansion and condensation cycle to remove heat efficiently, according to a guide published this month.
According to the latest situation of international agreements, governments around the world are gradually phased out the current hydrofluorocarbon refrigerants, such as R134a and R410A. The Montreal Protocol was originally set in 1987 to limit the use of previous generations of refrigerants that deplete ozone layer and to find new refrigerants to replace the refrigerants that cause global warming.

The Montreal Protocol was originally set in 1987 to stamp out a previous generation of reminders that depleted the ozone layer, and has been updated to Remove their replacements, which cause global warming.
In the United States, new refrigerants will no longer be able to use hydrofluorocarbons from January 2024.
In the US, new chillers cannot use HFCs from January 2024.
In the chiller unit and refrigerator, working fluids like hydrofluorocarbon will evaporate and condense. Some people believe that hydrofluorocarbons can be replaced by water, but others proposed carbon dioxide as early as 2006. In the international chemical list, carbon dioxide is called R744.
In chillers and refrigerators, a working fluid such as an HFC evaporates and condenses. Some have suggested that HFCs can be replaced by water, but others have proposed CO2, as long ago as 2006. International chemical listings, CO2 is referred to as R744 .
This is against common sense because carbon dioxide is the ultimate greenhouse gas, but the global warming effect of hydrofluorocarbons is thousands of times greater than carbon dioxide. Arnold Magcale, chief scientist at Nautilus Data, believes that isolating carbon dioxide in refrigeration systems may reduce carbon emissions in data centers: "We can be the leader in carbon sequestration," he told DCD in March 2022.
This is counterintuitive, as CO2 is the definitive greenhouse gas, but HFCs have a global warming effect thousands of times larger than CO2. Arnold Magcale, the chief scientist of Nautilus Data, has suggested that sequestering CO2 in cooling systems could make data centers carbon negative : "We could be the leaders in carbon sequestration," he told DCD in March 2022.
Canadian-based Carnot Refrigeration Company has been shipping a series of carbon dioxide refrigerators to data centers since 2012 and was acquired by M&M Refrigeration Company in 2019.The company claims that in addition to reducing the environmental impact of chillers, CO2 can also achieve more efficient systems, saving 90% of the energy consumption of traditional systems.
Carnot Refrigeration, based in Canada, has been shipping the Aquilon range of CO2-based chillers to data centers since 2012, and was bought by US-based M&M Refrigeration in 2019. The company claims that as well as lowering the environmental impact of a chiller , CO2 makes for more efficient systems, which can save 90 percent of the energy consumption of conventional systems.
This report, titled "Refrigerant Limitation: Is Your Data Center Ready to Transition?" explains the technical and regulatory context and includes a research case where a data center in Quebec switches to CO2-based refrigeration When the system is used, the energy used for cooling is reduced by 60%. The guide is linked from R744, a website dedicated to carbon dioxide refrigeration.

Karno Refrigeration said: "This white paper shows that CRAC equipment uses carbon dioxide as a refrigerant to improve data center process, reduce costs and reduce the use of equipment with high global warming risks. “We know that making this change demonstrates a commitment to the environment while helping our data center customers find a solution to refrigeration technology that meets their needs.”
” This white paper demonstrates how CRAC equipment using CO2 as a refunderant improves data center processes, reduces their costs and reduces the use of equipment with high global warming potential,” said Marc-André Lesmerises, president of Carnot Refrigeration. “We know that making this change demonstrates a commitment to the environment and it's exciting to help our data center customers find a solution to cool their data centers that meets their needs and the needs of the planet."
