The HFO-1234yf saturation data were compared to those provided by Minor and Spatz (2008). Title: Microsoft Word - HFO-1234yf - Saturation Properties Table - SI+IP.pdf Author: e381246 Created Date: 20100420170931Z Although it is not mandatory to recover R1234yf, it is still good environmental practice and, due to the cost of this refrigerant, it would be advisable to do so. This refrigerant, designated R1234yf, belongs to the group of hydro fluoro olefins (HFO). Who can certify my qualifications for a licence application? Opteon® YF (R1234yf) is a next generation refrigerant gas that combines environmental benefits with excellent cooling R1234yf has a unique vehicle quick release fitting, to prevent use of incorrect equipment not fit for this type of refrigerant. Special hazards arising from the substance or mixture Flammable gas. The R1234yf system refrigerant circuit is accessed using service couplers that are a different size to those of a R134a system. Recovery/reclamation equipment (A2L compliant). Can I convert an existing R410A system to R32? Opteon™ YF (R-1234yf) Automotive Refrigerant. Solstice® yf Refrigerant (R-1234yf) 000000023899 Version 1.0 Revision Date 08.01.2019 Page 4 / 29 SECTION 5: Firefighting measures 5.1. THERMODYNAMIC PROPERTIES HFO-1234yf thermodynamic properties are very similar to R-134a as shown in Table 1 and Figure 1. By Alec Johnson Mar 20, … Conventional mobile air conditioning (AC) systems use hydrofluorocarbon (HFC) refrigerants, which are composed of hydrogen, fluorine, and carbon atoms connected by single bonds. Opteon™ YF (R-1234yf) is a hydrofluoroolefin (HFO) refrigerant that has the same chemical elements but contains one double bond between one set of the carbon atoms. This makes it a versatile compressor oil for many of today’s air conditioning systems. Check with your refrigerant wholesaler. Opteon™ YF (R-1234yf) Automotive Refrigerant Driven to Perform, Frequently Asked Questions About Using Opteon™ YF, Opteon™ YF Packaging, Handling, Storage Guideline, Opteon™ YF Thermodynamic Properties (Eng), Opteon™ YF Compatibility With Plastics and Elastomers, Freon™ Refrigerants for Mobile AC Systems, Opteon™ Working Fluids for Thermal Management, Zero ozone depletion potential (ODP) and very low GWP, Similar energy efficiency and capacity to HFC-134a. R12 - commercial industry standard - is ¼” flare female with a knurled nut). Dedicated cylinders for recovered or new R1234yf have a left-hand valve thread and require a suitable adaptor to connect to the gauge set charge hose. Both R134a and R1234yf may ignite when in contact with extremely hot surfaces or engine parts, releasing toxic hydrogen fluoride gas, but the Honeywell R1234yf refrigerant can do so at lower temperatures. Meet a new generation of refrigerants that exceed automaker requirements. This retrofit refrigerant replaces R-12 in chillers, home appliances, and more. What is the time frame for implementation of a licence type for marine engineers and other maritime personnel handling refrigerants? Chemours™ and the Chemours Logo are trademarks or registered trademarks of The Chemours Company. Who needs a refrigerant handling licence? R-1234yf Refrigerant Pressure Temperature Chart. Asphyxiation and freeze burns are also a risk. 1234yf: Excellent Elastomers Compatibility ND8 PAG at 100°C for two weeks Refrigerant Elastomers Rating 24 h Post Linear Swell % 24 h Post Weight Gain % 24 h Post Delta Hardness 1234yf Neoprene WRT 0 0.0 -0.3 1.0" HNBR 0 1.6 5.5 -7.0" NBR 0 -1.2 -0.7 4.0" EPDM 0 -0.5 -0.6 4.0" Silicone 1 -0.5 2.5 -14.5 "Butyl rubber 0 -1.6 -1.9 0.5 However, a licence is required if it is part of a blend containing a controlled HFC refrigerant. HFO-1234yf is a climate-friendly refrigerant. Technicians need to take the relevant safety measures for the correct transport, storage and handling of a flammable gas. It’s about the same as Freon 12 as a refrigerant, but its effect on the ozone layer is insignificant. R1234yf is not controlled under Australia’s Ozone Protection and Synthetic Greenhouse Gas legislation. R1234yf is classified as an A2L mildly flammable refrigerant, and requires the use of equipment designed for use with such a refrigerant. In addition, R134a will still be available, and in older systems, for years to come. However, mixtures containing these HFOs have not been investigated comprehensively as indicated by the data sets listed in Table 1, which were found during a … It is a legal requirement that automotive workshops who provide air conditioning services (including recovery) continue to hold a refrigerant handling licence and refrigerant trading authorisation if R134a is being used. R1234yf is a hydrofluoroolefin (HFO) refrigerant. R134a and R1234yf are similar, however, R1234yf was created as a more environmentally friendly replacement to R134a. The suggested refrigerant substitute is R1234yf, which has same properties of thermodynamics and a reasonable replacement of retrofit for R134a with changes in expansion valve. That same year, General Motors (GM) began using it in the Cadillac XTS. However, BG Frigi-Quiet® for R-1234yf, PN 702, is suitable for use in systems that use R-1234yf and R-134a because it was formulated with extremely high quality and purity oil in order to suit the performance requirements of both refrigerants.. https://refrigeranthq.com/r-1234yf-refrigerant-fact-info-sheet The “new” R 1234yf refrigerant has a different chemical composition and thus other properties than R 134a. Think this won’t happen? M. Richter, M. O. McLinden, and E. W. Lemmon. Extinguishing media Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Learn about the benefits of Opteon™ YF low GWP Automotive Refrigerant (HFO-1234 yf) for automotive airconditioning systems around the world. Once I apply for a Refrigerant Handling Licence, how long does it take for my licence application to be processed? Before the actual application of alternative refrigerants, thermophysical properties of mixed refrigerants need to be carefully investigated. The biggest difference between the two, is that R1234yf is mildly flammable and does require special handling. A collaboration of TEXA and Chemours. This is based on the MAC Directive (2006/40/EG), passed in July 2006. Do I need a permit through the ARC to handle and buy R32? The manifold gauge set is designed to take the male fittings of the hose set and are calibrated to read R1234yf temperatures. HFC-134a refrigerant has a GWP of 1,300; Opteon™ YF has a GWP < 1. The double bond makes a big difference. In 2014, Fiat Chrysler began filling the air conditioning systems on almost all of its models with R1234yf refrigerant. 2. Diagnosis of the air-conditioning system can be done in the same way as with R134a.
