WebHow is the vacuum measured?, A pressure of 1 bar is approximately equal to: and more. ... A refrigerant properties chart calls for 100 psia. The reading you would see on your gauges is: 100 psia - 15 = 85 psig (rounded). A refrigeration system was checked for leaks. The system temperature and surroundings were 75°F when the system was charged ... WebAug 14, 2024 · psia is absolute pressure. What you're probably seeing below zero is actually inches of mercury. Atmospheric pressure is like 30 inches of mercury, so they often put inches of mercury below zero rather than psi. If the scale was psia, it would start at just under 15 and go down to zero.
