What is the typical discharge pressure of refrigerant vapor exiting the compressor under normal conditions?

• A. 154 PSIG
• B. 184 PSIG
• C. 200 PSIG
• D. 130 PSIG

Answer: (A)

The typical discharge pressure of refrigerant vapor exiting the compressor under normal conditions can vary based on the type of refrigerant used and the specific application of the refrigeration system. However, a common discharge pressure for many refrigerants in standard commercial refrigeration settings often falls around 154 PSIG. This pressure allows the refrigerant vapor to adequately travel through the condenser, where it will be cooled and condensed into a liquid to continue the refrigeration cycle effectively. Factors such as ambient temperature and system design can influence the discharge pressure, but the selection of 154 PSIG reflects a common value for several common refrigerants and operational parameters. Understanding this typical discharge pressure is crucial for maintaining system efficiency and ensuring the refrigerant cycle operates optimally.
