News The refrigerant HFC-134a, tetrachloroethane, has zero ozone depletion potential. At present, the main refrigerants used in household refrigerators are R12 (CFC-12), R134a (HFC-134a), R600a (HC-600a), and so on. The application technology of replacing R12 with HFC-134a refrigerant is becoming more and more mature. The box structure, refrigeration system, and… It's the same thing so yes. 8. MonMotha. • 4 yr. ago. Two names for the same thing. 3. y_3kcim. • 4 yr. ago. R stands for refrigerant, hfc stands for Hydrofluorocarbons, the chemical makeup of the refrigerant. 10.5.1 The amount of cross contamination of CFC-12 in HFC-134a or HFC-134a in CFC-12 shall not exceed 0.5 percent by weight as determined by gas chromatography. A sample of vaporized refrigerant liquid shall be separated and analyzed by gas chromatography. A 1% SP-1000 on Carbopack B (60/80 mesh) column may be used for the analysis. 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. The application of a mixed refrigerant HFO1234yf/HFC134a (89:11, by mass) of GWP 144 in a vehicle air-conditioner system with and without an internal heat exchanger was studied under refrigerating and heating conditions, and it was compared with an R134a original system. The results show that under refrigerating conditions, the refrigerating capacity of the HFO1234yf/HFC134a system with an R134a is a HFC, used in automotive air conditioning and as a replacement for R12 and R22 in medium and high temperature refrigeration applications, such as commercial and domestic refrigeration and chillers. R-134a is an HFC refrigerant, which requires polyolester (POE) lubricant to be used in the compressor. R-134a and 1234yf systems are very similar to each other. In fact this was one of the reasons that 1234yf was chosen as an alternative refrigerant. A few of the major differences can be read below: Slight design differences in the design specs of certain components like TXVs, ports, evaporators, and condensers. Service ports are different then HFCs are a class of chemicals used as refrigerants, in fire suppression systems, and in certain scientific equipment. HFCs are greenhouse gases (GHGs) with global warming potentials (GWPs) hundreds to thousands of times higher than carbon dioxide. The United States (U.S.) Environmental Protection Agency (EPA) is implementing the HFC phasedown .

is hfc134a the same as r134a
