CC7.26.5/1117-1217/E 1/8 Date of last update: Dec-17 Ref: CC7.26.5/0117-1217/E Application Engineering Europe REFRIGERANT CHANGEOVER FROM HFC R134a TO HFC/HFO R450A & R513A WARNING Use only Mechanical Code 2015 of Utah > 11 Refrigeration > 1103 Refrigeration System Classification > 1103.1 Refrigerant Classification 605.3 Building Services and Systems, Refrigerant Classification example, R-134a). Due to the nature of R134a properties which is of a HFC (hydrofluorocarbon) refrigerant, it does not have any ozone depletion potential and has little greenhouse effect. refrigerant can replace it (Annex 1 table 2 shows the HCFC phase-down steps). Our goal is to improve the safety, efficiency, and productivity of industrial refrigeration systems and Refrigerants regulated under the Refrigerant Management Program (RMP) include any refrigerant that is an ozone depleting substance (ODS) as defined in Title 40 of the Code of Federal Regulation, Part 82, and any compound with a global warming potential (GWP) value equal to or greater than 150 according to the GWPs specified in IPCC's fourth Assessment Report of 2007. It can be used for recharging Table 3 summarizes typical data for both HFC-134a and CFC-12. HFC refrigerants are composed of hydrogen, fluorine and carbon atoms connected by R-134a For full Thermodynamic properties of refrigerant R-134a, also known as 1,1,1,2-tetrafluoroethane, R-134a, Freon 134a, Forane 134a, Genetron 134a, Florasol 134a, Suva 134a or HFC-134a and norflurane (INN). Refrigerant blends having the same pure components but with different compositions are identified with an upper case letter after the number (for example, R-401A and R-401B). Refrigerant (R-134a) Thermodynamic Properties (SI Units) 2 Equations The MBWR equation of state was used to calculate the tables of thermodynamic properties.

The Industrial Refrigeration Consortium is a collaborative effort between the University of Wisconsin Madison and industry. Point T, C p, kPa u, kJ/kg v, m 3/kg x Phase description 1 -10 300 2 … In addition to fluorine and carbon, Freons often contain hydrogen, chlorine, or bromine. Table 1, on pages 4 and 5, shows the properties of R-22 at satur ation.It will be used in the examples that follow. Specify each state on T-s diagram ( 4 Marks). 1 December 12, 2013 Safety Bulletin Maximum Refrigerant Quantities per Occupied Space Derivation of values for Table 1, CSA B52-13 for A1 and B1 Refrigerants Introduction This information bulletin serves to provide additional Thus, Freons are types Refrigerant Table: Explanation and Glossary of Terms A reference list of refrigerants which is intended to provide an indication of the basic characteristics, properties and applications for a variety of refrigerants along with some The current leading refrigerant, HFC-134a is a hydrofluorocarbon refrigerant, while Opteon ® YF (HFO-1234yf) is a hydrofluoro-olefin refrigerant. In October 2016, the HFC phase-down steps were agreed upon and became part of the Montreal Protocol, (also called the Kigali amendment).

R-134a has the formula CH2FCF3. Calculation of thermodynamic state variables of Tetrafluorethan - R134a in saturation state, boiling curve Lower limit for calculation: -90 C, 0.015 bar bar upper limit: 100 C, 39 bar. R134a Refrigerant is a common refrigerant that is used in many air conditioning applications, usually packaged in blue colour cylinders. Visual ratings are listed for the neat lubricant, the lubricant/ refrigerant solution and the three metals that were present in the lubricant/refrigerant This is a haloalkane However, all Complete the following table for refrigerant 134a ( 16 Marks). R-22 will soon be phased out, so you will not see it as much as you do other refrigerants in the future. composition products.
