1,1,1,2-Tetrafluoroethane (also known as norflurane ( INN ), R-134a, Freon 134a, Forane 134a, Genetron 134a, Florasol 134a, Suva 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….
* These refrigerants have not been marketed yet; therefore, fittings have not been developed. + Direct final rule published March 26, 2012 and effective May 21, 2012 changed this to a left-handed screw fitting with diameter 8/16 inches and Acme shaped threading with 16 threads per inch, consistent with SAE J 2844 (October 2011 edition).
HCFC-22 (CHClF2) and HFC-134a (CH2FCF3) are two major gases currently used worldwide in domestic and commercial refrigeration and air conditioning. HCFC-22 contributes to stratospheric ozone depletion, and both species are potent greenhouse gases. In this work, we study in situ observations of HCFC-22 and HFC-134a taken from research aircraft
A chemical with an atmospheric lifetime close to or exceeding that of HFC-134a is an unlikely candidate for use in motor vehicle air conditioning. HFC-227ca has an atmospheric lifetime of 15 years, approximately the same as the 14.6* year lifetime of HFC-134a.
Effect of condenser fouling is evaluated on the performance of a vapour compression system with refrigerants HFO1234yf and HFO1234ze as an alternative to HFC134a. The condenser coolant temperature has been varied between 35 and 40°C to evaluate the effect of fouling at different condenser temperatures. A simulation model is developed in EES for computing the results. The results have been
The problem with R134a conversion. In the years following the switch to R134a, there was confusion over what was required to maintain the A/C of older cars. With new R12 no longer being manufactured, the market price soared to $100/pound. And with R134a costing only two bucks a can, converting to the new inexpensive refrigerant seemed the thing
Hi, Is HFC-134a the same as R134a and if not whats the difference? Thank you very much, LoveCoolAir . Chick on Mon June 27, 2005 1:16 PM . same thing
What is an HFC-134A Refrigerant? Published 08/31/2017 06:10 AM | Updated 11/02/2021 02:45 AM HFC-134a is a chlorine-free fluorinated refrigerant designed as a non-ozone depleting replacement of CFC-12.
The same category also includes the refrigerant blends R516A (ARKEMA ARM 42) and R456A (Koura/Mexichem AC5X). All options show refrigerating capacity, power input, and pressure levels similar to R134a. Thus, components and system technology can be taken over, only minor changes like superheat adjustment of the expansion valves are necessary.

is hfc134a the same as r134a
