At the high end, the pressure of A is We are, of course, talking about A liquid pressure. The difference between these two pressures is quite insignificant and in practice, we usually just take the pressure of the A refrigerant in liquid state for various calculations. Since we use a gauge meter to measure A pressures, the unit we use is not psi pounds per square inch but psig pounds per square inch gauge. If you check the chart above, you can see that the pressure of the liquid RA refrigerant is If you are measuring the pressure of a A gas vapor , your gauge meter should read
