AHRI and NRDC issue joint letter supporting EPA SNAP proposal to prohibit R134a, R410A and R407C in new chillers from 2025.
The US Environmental Protection Agency (EPA) updates its list of low GWP refrigerants
The US EPA has added new lower GWP refrigerants and expanded the acceptable uses of others in its latest changes to the Significant New Alternatives Policy (SNAP) programme.
A low-GWP cooling system for the Eiffel Tower
The ageing R407C cooling system in the tower’s west pillar has been replaced with an energy efficient system using low GWP R1234ze(E).
France: a HFC price commission before an index from INSEE (in French)
During SIFA, the Snefcca (French national union of refrigeration, kitchen equipment and air conditioning companies) confirms deadlines and framework of the future index from INSEE (French national institute for statistics and economic studies)...
Low GWP blends for domestic air conditioning
A review article presents the latest research trends on low GWP refrigerants, mainly HFC/HFO blends, for domestic air conditioning.
IIR GL2020 conference: Range of CO2 applications
Almost half of the presentations at the IIR Gustav Lorentzen conference in Kyoto focused on CO2, in commercial refrigeration systems but also in many other applications. Overview of these...
Price increase for HFCs
Chemours, Mexichem and Arkema have announced 10-15% rise in cost of several HFCs from 1st January 2016
Recycling could significantly cut down emissions from HFC production
A team of researchers estimated that with 30% of recycled refrigerants in the annual output, CO2 emissions from the production of R134a could be reduced by about a...
EU Regulation on fluorinated gas impacts
The revised regulation on fluorinated gas No 517/2014 was published on May 20, 2014 in the Official Journal of the European Union. It entered into force on June 9 and will apply from January 1, 2015.
US EPA proposes to prohibit certain high-GWP HFCs in MAC and retail refrigeration
EPA proposed in July 2014 to change the status of certain HFCs with high GWP previously listed as acceptable under the EPA’s SNAP Program to unacceptable in several end-uses.
US: Court strikes down EPA restrictions on HFCs
In August, the US Court of Appeals for the District of Columbia (D.C.) overturned Environmental Protection Agency (EPA) directives to ban certain high GWP HFC refrigerants.
US: EPA confirms two rules to reduce HFC emissions.
HFC phase-down: The US Environmental Protection Agency (EPA) announces a ban on a number of HFC refrigerants in certain applications and tightens leak rate rules.
New HFO/CO2 blends in the pipeline
The refrigeration and air-conditioning sector has long been divided into two distinct camps, that promoting natural refrigerants and that developing low-GWP fluorocarbons. But could this be about to change?
Mexichem, DuPont and Honeywell announced new HFO-based alternatives for R404A and R134a
M. Cooper, sales manager for Mexichem, revealed in RAC the manufacturer’s offering for stationary refrigeration would be based on its AC5 refrigerant (R444A) which has been undergoing development as a mobile air-conditioning refrigerant....
