There is increased confidence that trifluoroacetic acid (TFA) produced from degradation of HFCs, HCFCs, and HFOs will not harm the environment over the next few decades. This assessment is based on the current estimates of future use of hydrofluorocarbons, HCFCs, and HFOs. It is noteworthy that HFCs and HCFCs have atmospheric lifetimes…
An HFO insulation spray foam has been selected as the best green building product at the 2019 International Builders’ Show in the USA. As well as a non-flammable blowing agent with GWP 1 and thermal efficiency, the foam is sprayed from reusable containers, provides air and radon barriers (particularly important for Canada), uses 12.5% post-consumer…
Introduced in 2018 (see EFCTC Newsletter No159 July-August 2018) the Hybrid VRF has been awarded the Low Carbon Initiative prize at the Edie Sustainability Awards. It combines variable refrigerant flow and chiller technologies, using water throughout the majority of the pipework to transfer simultaneous heating and cooling to different rooms and offers…
The use of 2 fluorocarbon refrigerants for vehicle mobile air-conditioning has the potential to lead to cross contamination of R-134a or R-1234yf. Almost 100% of new passenger cars sold in the EU use HFO-1234yf as refrigerant as a result of the EU MAC Directive and HFO-1234yf is being adopted in the USA due to the…
EFCTC Sponsors Illegal Trade Action Line. In response to rapid emergence of illegal traffic of Hydrofluorocarbons (HFCs- or refrigerants) across the European Union, and in order to assist the EU and Member States, EFCTC has launched a programme to fight against this illegal trade. EFCTC has engaged the services of a specialized consultant that has…
Dr Gordon Dobson, a University of Oxford physicist, became interested in measuring ozone in the stratosphere in the 1920s. His first spectrograph used a photographic plate technique, which was inconvenient as the photographic plates were returned to Oxford from around the world for development and measurement. Around 1927, he built his photoelectric spectrophotometer which enabled…
