Impact of inclination changes on a liquid-to-liquid vapor compression cycle - cooling capacity and liquid flooding

The operation of vapor compression cycles at varying orientation with respect to gravity has rarely been investigated, except in a few studies preparing refrigeration for space applications. While two-phase flow inclined tubes is an active field research, the translation findings systems, such as cycle, unclear. For example, common hypothesis that independent under high refrigerant velocities not validated systems. In this paper, test stand investigate inclination dependence cycle described and system level indicator presented decreases increasing mass flux until 10 kg/(m2 ∙ s) evaporator. higher rates, shows constant dependence. Additionally, it shown intensity liquid flooding suction line due increases charge.
