1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
Originally, Section 612 was limited by ozone-depleting chemicals. However, after passing regulations to phase-out R134a, an HFC refrigerant with no ozone-depleting potential, this phase-out was defended by a subsidiary of DuPont siding with the EPA as it was challenged by a major manufacturer of R134a, and was struck down in 2017.
R-12 was used in automotive air conditioning systems until the mid-90s when production was banned by the government and replaced with a new refrigerant, R-134a. R-12 can still be bought and sold but is no longer produced. This makes R-12 very expensive and hard to find. [41] R-12’s global warming potential number is very large at about 11,000 ...
Feb. 27—AUSTIN — Governor Greg Abbott on Tuesday issued a disaster declaration for 60 Texas counties in response to widespread wildfire activity throughout the state. Additional counties may ...
Puddles of ice and water mix on roads of Fort Worth on Wednesday, Feb. 1, 2023. Tarrant County is one of many in North Texas under an ice storm warning until 9 a.m. Thursday morning.
Hyundai is telling the owners of nearly 1,600 Nexo hydrogen fuel cell vehicles in the U.S. and Canada to park them outdoors and away from structures due to the risk of fuel leaks and possible fires.
This ruling allows HFO-1234yf to take over in applications where ozone depleting CFCs such as R-12, and high GWP HFCs such as R-134a were once used. [65] The phaseout and replacement of CFCs and HFCs in the automotive industry will ultimately reduce the release of these gases to atmosphere and in turn have a positive contribution to the ...
Statewide vaping ban: Effective September 30, 2021, according to Chapter 3794 of the Ohio Revised Code, vaping is prohibited in all places where smoking is prohibited (which includes bars and restaurants), with the exception of retail establishments that make at least 80% of their gross revenue from the sale of vaping products.
