What can an RMO estimate from the saturation pressure reading at an evaporator?

The correct choice reflects the relationship between the saturation pressure reading and the temperature in a refrigeration system. Specifically, in an evaporator, the saturation pressure corresponds to a specific saturation temperature for the refrigerant being used. When the refrigerant absorbs heat from the surroundings, it evaporates at this specific temperature.

By knowing the saturation pressure, an RMO (Refrigeration and Mechanical Operator) can determine the saturation temperature, which is critical in understanding the operational efficiency of the evaporator. This temperature relates directly to the temperature of the chilled water being supplied, as the water absorbs heat from the refrigerant during its evaporation process.

Overall, the saturation pressure reading provides valuable information about the thermal dynamics of the system, particularly about the temperature of the chilled water, enabling optimal functionality and energy management within the cooling process.
