What is the pump discharge header pressure in PSIG?

The pump discharge header pressure is a crucial measurement in understanding the operation of a refrigeration system. In the context of industrial refrigeration, the pressure in the discharge header indicates the effectiveness and efficiency of the circulating refrigerant. The value of 20 PSIG is often viewed as an optimal pressure for certain systems, allowing for adequate flow while minimizing the risk of system strain or potential damage.

This pressure helps to ensure that the refrigerant is effectively transported throughout the system, allowing for efficient heat exchange and maintaining optimal performance. It represents a balance between pressure and flow rate, ensuring that the system operates within its design parameters.

Understanding the typical operational pressure, such as 20 PSIG, aids operators in troubleshooting and optimizing systems, as deviations from the norm can indicate issues such as pump inefficiency or restrictions in the system.
