What do the saturated liquid line and the saturated vapor line show us in the basic refrigeration cycle?
These lines show us the refrigerant has reached the 100 percent point. For example, saturated liquid means the refrigerant has reached 100 percent liquid (point 4) and there is no vapor. Saturated vapor mean refrigerant is 100 percent in vapor state (point 3 and 8). The area on the left side of the curve represents the sub-cooled liquid refrigerant region. The sub-cooled region is heat removed (sensible heat) after the refrigerant has reached the 100% saturated liquid state. The saturated liquid state in point 4 (The intercept between high-pressure line and saturation curve). The area under the curve represents latent heat or a mixture of vapor and liquid region (point A to B). Heat that causes the refrigerant to change state, vapor to liquid or liquid to vapor. Within the saturation curve a refrigerant splits into two sections vapor or liquid: • To the left of the center line within the saturation curve, the refrigerant is in more of a liquid state. • To the right of the center within
