R1234yf label

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

Hydrocarbon refrigerant hose warning label

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

US EPA Approves HC Refrigerants

The United States Environmental Protection Agency (EPA) has approved hydrocarbon refrigerants R170 (ethane), R600a (isobutane), R290 (propane) and R441A (a blend of all four) for use in certain stationary refrigeration and air conditioning applications. The EPA has not changed its position on the use of hydrocarbon refrigerants in motor vehicle air conditioning (MVAC) systems, with Continue reading US EPA Approves HC Refrigerants

Ozone layer cycle

A rapid increase in atmospheric concentrations of dichloromethane – an ozone-depleting substance not controlled by the Montreal Protocol – has been discovered by scientists from the University of Leeds in Britain. While the current rate of ozone-depletion by dichloromethane is small, because it attacks ozone at the lowest altitudes of the stratosphere it has a Continue reading New ozone threat

Who owns vehicle telematics data?

Who owns the data generated by modern ‘connected’ vehicles in their day-to-day running and who should have access to it? What are the anti-competitive, privacy and civil rights implications of vehicles that can store and transmit data on location, usage and countless other factors as well as technical and diagnostic information? These questions represent a Continue reading Who owns vehicle telematics data?
