What is the specific evaporator pressure value noted?

In industrial refrigeration systems, the specific evaporator pressure correlates directly with the temperature at which the refrigerant boils in the evaporator. This pressure value is critical for the efficiency and performance of the refrigeration cycle.

The choice of 8.7" HG represents a common pressure used in various refrigeration applications, where it is essential to balance the desired cooling effect with system efficiency, load requirements, and the characteristics of the refrigerant involved. At this specific evaporator pressure, the refrigerant is able to absorb heat efficiently from the space being cooled, ensuring optimal operation.

Understanding the significance of this pressure in relation to the system's design and operational parameters is crucial for maintaining system performance. The other values represent different pressures which may not be suitable for the specific conditions set by the system's design requirements, leading to either insufficient cooling or inefficiencies in the refrigeration cycle.
