What measurement is used for condenser pressure?

Condenser pressure is typically measured in PSIG, or pounds per square inch gauge. This measurement is crucial in industrial refrigeration because it reflects the pressure of the refrigerant vapor in the condenser relative to atmospheric pressure.

When monitoring the performance of a refrigeration system, knowing the condenser pressure helps assess the efficiency of the condensation process, which is vital for the overall effectiveness and safety of the system. It indicates how well the system can reject heat from the refrigerant to the environment, and maintaining appropriate pressure levels can prevent issues such as compressor failure or reduced cooling capacity.

Other pressure measurements such as PSIA (pounds per square inch absolute) would include atmospheric pressure in its readings, which is not typically how condenser pressure is represented since the gauge pressure (PSIG) focuses on pressure above atmospheric levels. Similarly, bar is a different unit measurement that is more commonly used in Europe for pressure reporting, while PSIF (pounds per square inch fluid) is not a standard measurement used in refrigerant pressure contexts. Therefore, PSIG is the most appropriate and standard unit for condenser pressure in industrial refrigeration applications.
