Developing Adiabatic Two-Phase Flow
… study was performed using H2FC-CF 3 - 1,1,1,2-Tetrafluoroethane (R134A) as a working fluid in three different transparent tubes. The flow was visualized using a high speed camera. To better (faster and more objectively) analyze the flow, a technique was developed to determine the separation …

Flash gas bypass concept utilizing low pressure refrigerants
… interest to elaborate the same approach in R134a or similar low pressure refrigerant A/C systems. The main reason for this is the fact that lower pressure fluids are more affected by pressure drop, therefore flash gas removal which reduces low system side pressure drop will be more …
