rnThe alternatives for the HCFCs,which are still in use,and the HFCs are the old refrigerants,substances like ammonia(R-717),the hydrocarbons(R-290,R-1270,R-600a),water(R-718)and CO_2(R-744).The selection criteria for refrigerants have to cover efficiency,safety,and environmental ...
As of January 1, 2023, any refrigerant with a GWP higher than 750 cannot be used in A/C systems. This mandate will extend to ice rinks and chillers in 2024. Further restrictions on purchasing and consuming HFC refrigerants are gradually being implemented, with dates being announced as they c...
Comparisons in COP are presented at various temperature levels for the different fluids. Specific features of the fluids are emphasized that have an impact on the best way to implement them. The comparison includes ammonia, water vapor and isobutane, plus several HFC's and HFO's. The ...
Refrigerant regulations are designed by the Environmental Protection Agency (EPA) to address how refrigerants are handled and recycled based on the type of equipment being used. There are currently four certification classifications: small appliances, high and very high pressure, low pressure, and unive...
R410A is a mixture of two HFC compounds: difluoromethane (CH2F2) and pentafluoroethane (CHF2CF3). These compounds are non-ozone depleting, which means they have less potential to harm the Earth’s ozone layer compared to legacy AC refrigerants like R-22. Many manufacturers, including Trane...
HFC refrigerants alone are credited with causing an estimated 0.5° C of warming in the global atmosphere.The need for compliance around the New Jersey Global Warming Response ActIn 15 days, a rule supporting legislation put in place 15 years ago requires that you have your sites registered in...
hydrocarbon refrigerants have replaced the use of HFCs in Europe since the mid-1990s, and global brands like PepsiCo and Coca-Cola began the shift to hydrocarbons more than a decade ago. To keep up with the changing regulatory landscape and key climate goals, HFC phase-outs are planned on ...
Effects of System Materials toward the Breakdown of Lubricants and Low-GWP Refrigerants Retrofits from R-22/mineral oil to HFC/ polyolester (POE) oil are known to cause contamination deposits to dislodge and move through the system, so this is a very important step in any retrofit of an R...
Ultimately, it will be interesting to see how the final months of the R22 refrigerant phase out unfold. While there are many other regulatory factors that complicate this matter further (e.g., California’s new refrigerant regulations and the state of HFC refrigerants), the important thing is ...
Now that HCFCs are being phased out, owners and managers are faced with the same decision: keep their current equipment and most likely pay higher premiums on refrigerant in the future, or move to chillers using HFC refrigerants such as R-134a or R-410A....
