Refrigerant manufacturer and supplier Mexichem has launched Klea R407H as a lower GWP alternative to refrigerants including R404A and R507 in medium and low temperature applications.
The result of a partnership with Daikin, Klea 407H has a GWP of 1495 and in many cases can be used as a drop-in solution. Efficiency testing has shown it to have comparable COP to both R404A and other replacement products, including HFO blends.
Honeywell today said it will end sales of Genetron 404A (R-404A) and Genetron AZ-50 (R-507) refrigerants in the European Union in 2018 as contracts permit, in order to meet the deadline set by the European Union’s F-Gas Regulations, which stipulate the phase-out of high GWP HFCs by 2020.
The company has acted ahead of the expected scarcity of high GWP products due to the F-gas Regulation phase-down schedule, which determines how much refrigerant can be placed on the European market each year, based on GWP.
Bitzer, the German compressor manufacturer, has published its latest refrigerant report.
The tests run by Ahold and refrigeration consultancy P.W. Vlaskamp B.V. from Dordrecht showed an 8% energy efficiency improvement after the retrofit using the R-449A refrigerant. In addition, without the extra 'abatement' costs, the entire retrofit would pay for itself within five years.
The EIA’s (Environmental Investigation Agency) Climate Campaign Lead, Avipsa Mahapatra, said:
“EIA welcomes this next step in a series of domestic actions to prepare the U.S. market for, and build a solid foundation toward, implementing a global phase down of HFCs.”
A-Gas Managing Director John Ormerod on how the phase down of HFCs in the UK and Europe compares to refrigerant use in other parts of the world.
Refrigerant quota reductions are approaching rapidly in the UK and Europe. This is already putting a considerable pressure on the supply chain and the refrigeration industry is beginning to face up to the prospect of shortages of high GWP HFCs. There are a number of alternatives available, ranging from low GWP HFCs and HFOs to natural refrigerants, which are opening a new window for end users and equipment suppliers.
Hydrofluorocarbons (HFCs) are proving to be more controversial than just the global warming they cause when leaked from air conditioning systems.
Here's a roundup of recent articles from the USA, UK and India discussing the controversial chemicals and what governments are doing about reducing HFCs.
