Thermodynamic Properties of R134a (1,1,1,2-tetrafluoroethane)
WebRefrigerant 134a is the working fluid in a vapor-compression heat pump system with a heating capacity of 60,000 Btu/h. The condenser operates at 300 lbf/in 2, and the evaporator temperature is 10°F. The refrigerant is a saturated vapor at the evaporator exit and a liquid at 120°F at the condenser exit. WebHeat capacity (liquid) at 25 C (77 F) : 1.46 Heat capacity (vapor) at 25 C (77 F) : 0.858 Lubricant : Synthetic Polyalkylene Glycol. R134a (1,1,1,2-Tetrafluorethane) was introduced in 1991 under a number of different trade names such as Klea 134a, Suva 134a, Freon 134a, Forane 134a, Genetron 134a, Florasol 134a or simply just HFC 134a. university of south florida iacuc

WebTable 4 lists the specific heat capacity at constant pressure of R134a refrigerant-oil mixtures in the saturated liquid phase from (267.15 to 303.15) K when the lubricant … WebJan 18, 2024 · The evaporating pressure, condensing pressure, and exhaust temperature of R600a are all lower than R-134a. The lower liquid density of R600a refrigerant makes its charging capacity 45% of R-134a. It has good refrigeration performance and its refrigeration capacity is 55% of R-134a. WebA Widely Used and Thoroughly Trusted Refrigerant Freon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges. university of south florida ischool
