Steam Quality vs Steam Purity

Steam quality and steam purity are topics which often get confused with each other.  Distinguishing the difference between the two will help you understand the unique impacts they have upon a steam system.

Understanding steam quality requires understanding vapor-liquid equilibrium in water. As heat is added to subcooled liquid water, it proceeds to the saturated liquid curve and becomes a saturated liquid (moving from incoming city water to point A). At the saturation point, any heat added to the water will form a vapor and the temperature will remain the same because all additional enthalpy (heat energy) being added to the system is being used to change the phase of the water from liquid to vapor.

How Chillers Work

Factories, warehouses, healthcare facilities, commercial buildings, and office spaces generate unwanted heat that must be removed from the process, equipment, or occupants inside. Chillers may be used to remove this heat by transferring it to the atmosphere either by air or water cooled chillers. At the heart of the chilling process is the evaporation of a liquid refrigerant into a gas. Two basic types of chillers include vapor compression and absorption. In this blog, we will focus on the vapor compression chiller.
