Automatic Controls for Industrial Refrigeration Systems

4. Hot gas bypass. This solution is applicable to compressors with fixed capacities and more typical for commercial refrigeration. In order to control the refrigeration capacity, part of the hot gas flow on the discharge line is bypassed into the low pressure circuit. This helps to decrease the refrigeration

Pure SF6 and SF6-N2 mixture gas hydrates equilibrium and

Oct 15, 2009· In this study, we investigated the pure SF6 and SF6-N2 mixture gas hydrates formation equilibrium aswell asthe gas separation efficiency in the hydrate process. The equilibrium pressure of SF6-N2 mixture gas was higher than that of pure SF6 gas. Phase equilibrium data of SF6-N2 mixture gas was similar to SF6 rather than N2.
