How much will hydrostatic expansion increase pressure per degree Fahrenheit for Ammonia?

The rise in pressure due to hydrostatic expansion for ammonia can be quite significant as it is influenced by the temperature changes of the refrigerant. When considering the performance and operation of refrigeration systems, especially those using ammonia, understanding the pressure-temperature relationship is crucial.

For ammonia, the specific increase in pressure per degree Fahrenheit of temperature growth typically ranges between 100 to 150 PSI. This is critical in maintaining system integrity and safety, as the significant increase in pressure could lead to equipment failure if not properly managed.

In contrast, the other options either underestimate or overstate the impact of hydrostatic expansion on pressure. Knowing the accurate pressure change assists operators in predicting system behavior during operational changes and ensures compliance with safety standards in ammonia refrigeration systems.
