Copeland: Managing CO2 Pressures and Oil Management Systems

Topics include an overview of the CO2 booster system, the differing
operating pressure dynamics and the importance of compressor
superheat; gas cooler/condenser types, their impact on system
efficiencies for high and low ambient and the importance of
stabilized flash tank pressures; high-pressure valve control logic
for sub- and supercritical modes and its impact on system
stability; and oil management systems.
