IEC votes down HC charge-limit increase
Proposed standard falls one vote short of approval, preventing charge limit for A3 refrigerants from rising to 500 g from 150 g in commercial refrigeration.
Proposed standard falls one vote short of approval, preventing charge limit for A3 refrigerants from rising to 500 g from 150 g in commercial refrigeration.
Voting against the IEC’s new hydrocarbon charge limit would put U.S. supermarkets at a disadvantage, says NASRC executive director.
A group of NGOs and companies today urged the International Electrotechnical Commission (IEC) to increase the charge limit on A3 (flammable) refrigerants to 500g when it votes on the issue this year.
So said NAFEM Show exhibitors, who differed on whether 300 g would be better than the IEC’s proposed 500 g limit.
A higher flammable refrigerant charge limit, likely to be approved in 2019, should broaden the market for hydrocarbons in commercial refrigeration, according to manufacturers.
The IEC’s final vote will determine whether a 500-g charge limit is enacted as an international standard.
Energy efficiency is the main focus of AHT’s Chinese customers, according to the Austrian OEM, which was exhbiting its propane cabinets at its own ChinaShop booth for the first time.
A draft HC charge limit increase will go to a final vote around the end of the year following its approval by an IEC subcommittee.
If rejected by 9 national committees, the current draft standard suggesting to move the limit from 150g to 500g for the commercial refrigeration sector will be put off the table for years to come.
