Rodney Smith from CoolCar Air-Conditioning Centre Hamilton conducted a mini survey on New Zealand-new cars displayed at the New Zealand Agricultural Fieldays near Hamilton in June 2015. He wanted to get a feel for what refrigerant was in the air-conditioning of the latest cars and talk to the sales staff on the stands. A similar review … Continue reading Snapshot of NZ new car AC refrigerant
The Abbott Government’s proposal to relax new vehicle importation laws and enable personal imports of new cars could accelerate the uptake of R1234yf in Australia if the legislation passes. On some production lines, only models destined for countries where low global warming potential refrigerants are either compulsory or receive fuel efficiency credits are fitted with … Continue reading New car import laws could accelerate R1234yf growth in Australia
When I tell people that a technique I use during A/C diagnostics is visualising myself as a refrigerant molecule making my way around the internals of an AC system, my audience often allows their focus to wander from the discussion at hand while trying to determine just how crazy I am. Accurate diagnostics demands an … Continue reading Hacksaw Education
Growing use of flammable refrigerants like R1234yf has prompted the United States Air Conditioning, Heating and Refrigeration Institute (AHRI) to establish a subcommittee that will review safety issues related to mildly flammable ‘A2L’ class substances. In addition to representation from the refrigeration and air conditioning sector, the safety subcommittee will comprise flammability experts and people … Continue reading More A2L flammable safety studies
World’s second-largest carmaker commits to R744 as AC refrigerant German automotive giant Volkswagen Group hit the headlines in March when it confirmed its pursuit of carbon dioxide as an air conditioning refrigerant as part of a plan to become the world’s most environmentally sustainable carmaker by 2018. According to German newspaper Frankfurter Rundschau, VW Group … Continue reading CO2 refrigerant for VW Group
But even mild flammability made industry acceptance a hard sell A leading engineer behind the development of new industry standard automotive refrigerant R1234yf concedes that flammability is its biggest drawback – but that apart from that it is close to being the perfect gas for car air conditioning systems. During an exclusive interview with SightGlass News at … Continue reading R1234yf ‘really close’ to perfect
Within five years the batteries used to power electric cars will hold twice as much energy, at half the cost compared with today, according to Bosch chairman Volkmar Denner. Exponential advances in battery technology will make electric cars more affordable and viable for everyday use, accelerating their uptake, while hybrids and plug-in hybrids will become … Continue reading EV battery capacity to double for half the cost by 2020
More than 1300 tonnes of banned ozone-depleting substances (ODS) were seized worldwide between September 2012 and April 2014 according to figures from the United Nations Environment Programme. Confiscations included 7370 items of equipment and 9513 cylinders of refrigerant, with most seizures being of R22 refrigerant, an HCFC, while others captured CFCs like R12 and illegally … Continue reading Huge illegal ozone-depleting substance haul
Much of the global automotive industry has adopted R1234yf as the standard refrigerant in new cars, primarily due to tightening overseas legislation over the global warming effect of refrigerants released into the atmosphere. R1234yf has a far lower global warming potential than R134a, which has been the sole industry standard refrigerant in automotive air conditioning … Continue reading R1234yf Facts
This warning label attached to a cylinder of hydrocarbon refrigerant could be the manufacturer’s admission that its product is no longer considered a direct ‘drop-in’ replacement for R134a. The warning criticises major hose brands and hose types used by major motor vehicle manufacturers and recommends the retrofit to a ‘full barrier hose’ in order to … Continue reading Hydrocarbon refrigerant hose-down
