An HFO-1233ze based reciprocating chiller has been chosen for the HFO’s very low GWP of 1, to cool the new Centre for Sustainable Chemistry at the University of Nottingham, which is designed to be carbon neutral.
Carbon Tetrachloride (CCl4) is an Ozone Depleting Substance with a relatively high ODP value of 1.1 (Montreal Protocol value). In response to continued questions about the discrepancy between CCl4 atmospheric observations and reported production and consumption, a workshop on "The Mystery of Carbon Tetrachloride" was organized in October 2015 by the SPARC activity on CCl4
For the renovation of the the oldest Strasbourg (France) swimming pool heating system, an old gas boiler has been replaced by 2 HFC-134a geothermal heat pumps, delivering each 558 kW heating and 482 kW cooling.
Following inquiries by end users of low GWP Fluorocarbon solutions, EFCTC has received a clarification from the Austrian Federal Ministry for Agriculture, Forestry, Environment and Water Management on the regulatory position of HFOs.
An HFC-134a based innovative cooling and heating project at one of the London Canary Wharf main buildings received an Award for Excellence for replacing the fresh air cooling and heating system, decreasing substantially the energy consumption while increasing capacity by 25 %.
The US Air Conditioning, Heating and Refrigeration Institute (AHRI) flammable refrigerants subcommittee, ASHRAE, and the US Department of Energy (DOE) are supporting a collaborative effort to fund research about mildly flammable (ASHRAE class A2L) refrigerants, such as HFC-32, HFO-1234yf or HFO-1234ze(E), in order to allow their safe use.
Over the past months, different interpretations have circulated on the definition of a “One-Component Foam” (OCF). As OCF is generally placed on the market in cans with a content of ≤ 1000 ml, the latter has been interpreted as a volume limit. It has been assumed by some that products fulfilling the definition of OCF in the F-Gas Regulation, but placed on the market in larger dispensing units, would not be covered by the ban in Annex III, point 8.
