Decafluoropentane. CF 3 CHFCHFCF 2 CF 3. 1,640. Some refrigerants are not single chemicals but a mixture of two or more chemicals, called blends. HFC blends may contain only HFCs, or HFCs mixed with other chemicals. For example, R‑410A is made up of 50% R‑32 and 50% R‑125.

Automotive Refrigerant (R-134a) Fact Sheet Freon™ 134a automotive refrigerant from Chemours, formerly DuPont™ Suva® 134a automotive refrigerant, is a known and trusted brand used by automotive service technicians around the world. Overview Freon™ 134a is a non-ozone depleting hydrofluorocarbon (HFC) refrigerant replacement for R-12.

The specifications of each component of the R134a and CO 2 systems are listed in Table 1. Energies 2018, 11, x The calorimeter facility (the same as that described in Liang et al. [20]) consisted

Worksheet 3: HFC and PFC Emissions from Refrigeration/AC Equipment: Screening Method Based on Emission Factor Based Approach. Step 1. Assembly Emissions. 1.1 Enter the type of Refrigeration/AC equipment in Column A (Optional). 1.2 Enter the number of units produced during the current reporting period in Column B.

Compressor oils have to be the right type and viscosity intended for use in each particular system. BG Frigi-Charge® for R-134a, PN 704, contains R-134a (as the name implies) and is only intended for use in systems designed for this refrigerant. BG Frigi-Quiet® for R-134a, PN 701, is a suitable compressor oil for systems utilizing R-134a, but

The thermal performance, non-toxic chemistry and stability are nearly the same between R-1234yf and R-134a. The primary difference between the two is R-1234yf being slightly more flammable. ASHRAE classifies R-1234yf as a “mildly-flammability” fluid (A2L); R-134a carries an A1 safety classification due to its lower flame propagation. HCFCs. HCFCs Compounds containing hydrogen, fluorine, chlorine, and carbon atoms. Although ozone depleting substances, they are less potent at destroying stratospheric ozone than chlorofluorocarbons (CFCs). They have been introduced as temporary replacements for CFCs and are also greenhouse gases. See ozone depleting substance. HFCs. calculation of constants for HFC-134a were performed for Du Pont at the National Institute of Standards and Tech-nology (NIST) under the supervision of Dr. Mark O. McLinden. The constants were calculated in SI units. For conversion of thermodynamic properties to Engineering (I/P) units, properties must be calculated in SI units and converted to ^{An interesting aspect of the debate regarding which refrigerant is the best replacement for R-134a may have something to do with cost. “Today R-134a costs about $120 for a 30 lb. cylinder. R-1234yf costs around $700 for a 10 lb. cylinder and R-744 costs $68 to fill a 100 lb. cylinder. The cost per pound works out as follows: R-134a at $4, R} R-134a 100 year GWP = 1300. R-12 100 year GWP = 10,600. R-22 is not controlled in the Kyoto Protocol for climate change because it was already being phased out by the Montreal Protocol for ozone depletion. If there was no Montreal Protocol, then all the CFCs and HCFCs would have been controled under the Kyoto Protocol.
