Honeywell Confident SAE International Evaluation Of Its New Automotive Refrigerant Will Reconfirm Safety Of Product

Honeywell has issued a statement saying the company is confident that SAE International will reconfirm that HFO-1234yf, Honeywell’s new low global warming-potential automotive air conditioning refrigerant, is safe for use in automobiles.

SAE International Cooperative Research Project Offers Update On R-1234yf Refrigerant

The SAE International Cooperative Research Project (CRP1234-4) team recently established to perform an updated engineering review of R-1234yf refrigerant usage in vehicles has issued on update on its progress.

VW’s Says it Will Not Use HFO-1234yf Refrigerant in New Vehicles

In a release from R744.com, Volkswagen chief Ferdinand Piech says “the right refrigerant is CO2” for mobile air-conditioning and decides against using 1234yf in new vehicles.

Tech Tip: Sign of Low Refrigerant

Join Dave Hobbs of Delphi Product and Service Solutions as he discusses some signs of low refrigerant in moodier automotive AC systems. He goes on to discuss how environmental factors such as ambient air temperature, and the AC system’s ‘cycling switch can cause low refrigerant like symptoms.

This clip is an excerpt from the comprehensive “A7 Test Prep Program” with Dave Hobbs, Coming Soon from Automotive Video.

Update on Global Automotive Refrigerant Contamination

Last month, MACS and Neutronics issued a warning advising that all industries using R-134a refrigerant immediately test all cylinders thought to be virgin R-134a (including new 30 pound cylinders) due to reports of widespread contamination. Following that report, Ed Sunkin, editor of Underhood Service, contacted manufacturers and suppliers of automotive refrigerant to comment on this issue.

MACS Issues Reminder on Refrigerant Usage in Mobile A/C Service

The Mobile Air Conditioning Society (MACS) Worldwide strongly recommends the use of a refrigerant identifier during mobile A/C service to inform the technician of the chemical content of the refrigerant in a mobile A/C system and to verify the content and purity of refrigerant purchased in cylinders.

MACS Issues Reminder On Refrigerant Usage in Mobile A/C Service

The 2011 mobile A/C service and repair season is approaching and the potential of increased cost of HFC-134a is a source of concern for the mobile A/C aftermarket. The concern is that market conditions will lead to improper refrigerant substitutions in mobile A/C systems. The Mobile Air Conditioning Society (MACS) Worldwide strongly recommends the use

Directions: GM Leads the Industry in the Race for a Greener Refrigerant

The switch to HFO-1234yf is expected to help GM vehicles meet the overall requirements of the U.S. EPA’s latest motor vehicle greenhouse gas regulations.

Supporters of R744 in Mobile A/C Systems Express Problems with 1234yf Refrigerant

The growing reluctance over 1234yf has now led its own proponents and Original Equipment Manufacturers (OEMs) to dreadfully search for a system solution that would enable the use of the refrigerant, no matter what the system cost and efficiency implications

Tech Feature: New Refrigerant Change May Not Be a ‘SNAP’

The introduction of HFO-1234yf in vehicle A/C systems in the U.S. could be a few years away. However, it is plausible that some (dealership technicians and collision repairers) may see HFO-1234yf systems by late 2011 and early 2012, as European models begin the R-134a phase-out and make their way across the pond. (R-134a is to be completely phased out of new European systems by 2017.)
