Pressure Enthalpy Chart For Air. With a little system information it possible to estimate the refrigerant charge required using the pressure enthalpy diagram. As you pass the sight glass you fart a few bubbles just to mess with.
2 displays all the pertinent properties for a given refrigerant in this example r22.

The blue line on the left of the bubble represents the 100 saturated liquid line.
The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition.
The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition. First an explanation of how the diagram is built up is given and then its use is describ ed.
