Flow Boiling of R134a and R134a/Propane Mixtures at Low Saturation Temperatures Inside a Plain Horizontal Tube

Journal of Heat Transfer, 2008
Abstract Local heat transfer coefficients for flow boiling of pure 1,1,1,2-tetrafluoroethane (R134a) and binary mixtures of propane (R290) and R134a were measured. The experimental setup employed a vapor heated plain horizontal tube (di=10mm, do=12mm, L=500mm). The measurements covered a wide range of saturation temperatures (233≤Ts≤278K)

Solubility measurements of R134a in nanolubricant

2014
In the last years, the employment of hydrofluorocarbons (HFCs) in Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) applications has gained a big increase, due to the necessity to substitute the old chlorinated refrigerants. However, HFCs are not compatible with the mineral oils (MO), widely used in the past.
