It is the percentage of a refrigerant that is either liquid or vapor. So looking at a R-22 Enthalpy chart, the first number at the base you see is 10. That 10 represents the percentage of vapor to liquid. In other words, you have 90% liquid at that point, and 10% vapor. As you move across the chart from left to right, that would be equivalent to the refrigerant boiling... as it goes through latent heat and the refrigerant boils off, the percentage of liquid to vapor gets smaller. When you get to 9... that is equal to 90% vapor/ 10% liquid. The outer lines of that dome shape would be equivalent to, on the left hand side, absolute liquid and all the way to the right hand side, absolute vapor.

Why HVAC is used?
HVAC (Heating, Ventilation, and Air Conditioning) systems are used to control indoor temperature, humidity, and air quality in buildings or spaces. They provide thermal comfort and maintain a healthy and safe environment by regulating heating and cooling, ensuring proper ventilation, and filtering air to improve indoor air quality. HVAC systems are essential for maintaining comfort, preserving building structures, and supporting human health and productivity in various settings, including homes, offices, hospitals, and industrial facilities.

How do you find out if lines are parallel?
If the distance between the lines is constant then they are parallel.
Are all the longitudes parallel?
All lines of constant latitude are parallel to all others,but no two lines of constant longitude are parallel.
What angle do lines of longitude cross with lines of latitude?
Meridians of constant longitude cross parallels of constant latitude. Parallels of constant latitude cross meridians of constant longitude. At each intersection of a meridian and a parallel, the lines are perpendicular (form 90° angles).
