At what pressure is the refrigerant measured at the outlet of the condenser under normal conditions?

The outlet pressure of the refrigerant from the condenser under normal operating conditions typically falls around 150 PSIG for many common refrigerants. This pressure corresponds to the saturated vapor pressure at the temperature of the refrigerant after it has been condensed.

In refrigeration systems, the condenser's main function is to reject heat from the refrigerant as it changes from a gas to a liquid, which occurs at high pressure. The actual pressure can vary slightly depending on the type of refrigerant used, the condenser design, and the operating conditions, but 151 PSIG aligns well with general industry standards for various refrigerants under typical conditions.

Understanding these pressures is essential for monitoring system performance, ensuring efficient operation, and avoiding potential issues that may arise from operating outside the expected pressure ranges. The correct answer encapsulates the expected operational pressure for a well-functioning refrigeration system in standard conditions.
