Discharge vapor leaving the MT compressors flows by way of an oil separator just before getting into the fuel cooler. In the event the ambient ailments are these types of that the saturated condensing temperature (SCT) is lower than 87.9°File, the CO2 vapor will condense into a liquid. With this situation, the technique will run similarly to a typical vapor compression cycle, Along with the liquid leaving the fuel cooler flowing into your receiver, and giving the liquid header as desired. In the event the SCT is higher than 87.nine°File, the fuel cooler transfers warmth with the discharge vapor and not using a transform of condition occurring.
