Flash gas bypass concept utilizing low pressure refrigerants
Flash gas bypass represents one of the prospective approaches to improve the efficiency of various small scale heat transfer systems that utilize refrigerant as a working fluid. It is characterized by the bypass of vapor created throughout the expansion process around the evaporator. As the …

Control of flash gas bypass mac system with emphasis on start-ups and transients
Flash Gas Bypass (FGB) approach has the benefits of eliminating refrigerant maldistribution and reducing refrigerant pressure drop across the evaporator. Most of the previous research on flash gas bypass focused on performance improvement in steady state and demonstrated that compared to direct …

Flash gas bypass - a way to improve distribution of adiabatic two-phase refrigerant flow in headers of microchannel evaporators
… presents an experimental and numerical study of flash gas bypass (FGB) method as a way to solve the existing problem of distribution of two phase adiabatic flow in headers of parallel flow evaporators, of typically microchannel design. Three main issues that will be explored in this thesis are: …

Two phase flow distribution in parallel flow heat exchangers -- experimentally verified model
… evaporator for two cases. In the first case, the flash gas bypass system, flash gas from the expansion valve is separated and only single phase liquid is supplied into the evaporator. The second case is a conventional direct expansion system where refrigerant enters the evaporator in a two-phase …
