That’s just the opposite of R12. Table 1. Refrigerant R134a is a commonly used refrigerant in vapor compression cycles, Table 1 below shows a comparison between the thermodynamic properties of   The refrigerant R134a is the chemical compound tetrafluoroethane. This refrigerant takes a significant step forward in environmental protection by achieving an ozone depletion factor of zero. 04 4. Thermodynamic properties of refrigerant R-134a. O. Baehr, “An International Standard Formulation for the Thermodynamic Properties of 1,1,1,2-Tetrafluoroethane (HFC-134a) for temperatures from 170 K to 455 K Troubleshooting modern refrigeration and/or air conditioning systems require a thorough knowledge of the systems and its functions. R134aTables Excel Add-In - Sample calculations in Excel. SI Units. 06°C. Chart 1: R12 ounces to R134a ounces. KEY: Similarly to R134a, R1234ze(E) is a medium pressure refrigerant with a slightly higher critical and boiling temperatures and lower critical pressure. Table 1B. GWP (Global Warming Potential) of the refrigerant must be low as it may cause an increase in global warming. 8. K. 06°C) Saturation Properties - Pressure Table (60 kPa - 3 MPa) R-134A Refrigerant Pressure Temperature Chart - R-134A is an inert gas also known as Tetrafluoroethane and is used in air conditioner systems. Critical Pressure: 4. R134a Refrigerant. Refrigerant R134a or HFC-134a was developed to meet these needs. Old equipment Instead of trying to explain everything in text I figured it would be easier to review in a table or picture. pdf from MECH 4414 at The University of Hong Kong. PAG150 = High. • E. The other approach to retrofit is the "quick and cheap" one. Both refrigerators and automobiles use R-134a as a refrigerant, and adults can buy it at most automobile parts stores. 38, 37, 42. 26 of each refrigerant during operation. Table 3 summarizes typical data for both HFC-134a and CFC-12. I pulled these tables directly from Chemour’s website. Restricted or capped external equalizer. (kg/m³) . Browse your favorite brands affordable prices free shipping on many items. 44 78. " Lower Cost: Less expensive than R12 refrigerant and R134a "retrofits". Can be used effectively in R12 or R134a refrigeration systems without major "retrofitting. R134a was and is used as replacement refrigerant besides several "drop-in" refrigerants (refrigerant mixtures). R134a is capable to be at temperatures of -28°C at room temperatures of 38°C, its performance being very similar to that of an R12. R. Refrigerant  Temp. 37 4. content and viscosity, while the refrigerant was examined for the presence of decomposition products.
