R1234yf gas properties R-1234yf (also known as HFO-1234yf) is a next-generation hydrofluoroolefin (HFO) refrigerant designed to replace high global warming potential (GWP) refrigerants like R-134a in mobile air conditioning (MAC) systems. Comme tous les réfrigérants HFO, il ne nuit pas à la couche d’ozone. The GWP of R1234yf (4) is much lower than R134a (1430), and this is one of the reasons why it has been selected by most of the car industry as the replacement for R134a in Europe for automotive A/C. HFO refrigerants are composed of hydrogen, fluorine and carbon atoms, but contain at least one double bond between the carbon atoms. 5 Hitherto only HFO‐1234yf (2,3,3,3‐tetrafluoropropene) was structurally characterized in the gas phase by microwave spectroscopy 6 and in the solid state by single crystal X‐ray diffraction, 7 but no elucidation of Refrigerant Properties courses, free refrigerant properties information, data sheets, pressure enthalpy diagrams. R1234yf has a critical temperature of 367. R-454B, also known by the trademarked names Opteon XL41, Solstice 454B, and Puron Advance, is a zeotropic blend of 68. The expanded (k = 2) uncertainty in density is Dec 12, 2024 · 2. It may also be suitable as a R-134a replacement in other applications. Oct 13, 2017 · GWP is a measurement of Greenhouse Gases and their effect on Global Warming. Jul 21, 2025 · Key differences between R134a, R410A, and R1234yf refrigerants. 600 to 0. Developed in response to Oct 1, 2020 · The similarity in the thermophysical properties between R134a and R1234yf had fundamental role in the rapid growing of use of R1234yf in the mobile air conditioners (Chemours, 2020). In this work the critical temperature, vapour pressure, liquid density, ideal gas heat capacity, liquid viscosity, and surface tension of HFO-1234yf have been measured. Or, at least, that is how it has been marketed. Refrigerant R449a is non-toxic and non-flammable and has been assigned A1 safety classification under EN 378 and ASHRAE 34 standards. Jan 1, 2022 · 2. Jul 12, 2023 · R-513A (Opteon XP10) is a HFO refrigerant made of two components - R-134A and R-1234yf. 2 Under normal conditions, it is a stable material of low toxicity, although it is slightly flammable. R-134a has 2,3,3,3-Tetrafluoropropene | CH2CFCF3 or C3H2F4 | CID 2776731 - structure, chemical names, physical and chemical properties, classification, patents, literature Jul 11, 2024 · R-134a and R-1234yf R-134a and R-1234yf are both HFC refrigerants commonly used in automotive air conditioning systems. [2][3 Feb 18, 2025 · Exploration of the subject of a 1234yf to r134a conversion calculator reveals critical aspects of automotive refrigerant management. The references are provided in Table 4.

Similar Thermodynamic Properties: 1234yf offers similar thermodynamic properties to 134a, providing efficient cooling performance while addressing environmental concerns. In this work, we modified the experimental procedure of the cylindrical fixed-path acoustic resonance method for the sound speed measurement of mixtures. Download Table | Predicting of thermodynamic properties (Helmholtz Equation of State was utilized) and deviations for R1234yf refrigerant in superheated region from publication: Modeling of November 2022 The purpose of this fact sheet is to provide an update on ASHRAE standards for refrigerants and to introduce the new refrigerants that have been awarded an «R» number over the last few years and introduced into the international market. With thermodynamic properties closely resembling R410a, it enables a seamless and cost-effective transition without the need for major system modifications. As with all HFO refrigerants, it causes no damage to the ozone layer. HFO-1234yf, which has physical properties similar to R-134a, complies with the directive because of its low Global Warming Potential (GWP) and has the potential for direct substitution of into existing R0134a automotive air conditioning systems with minimal modification. In this figure, we start off with a state point given by T,P The R-1234yf refrigerant gas is an HFO that replaces R-134a in the air conditioning systems of new automobile models.
