Glossary
condenser A component of the absorption refrigeration system in which refrigerant vapor is converted to liquid as it rejects heat to cooling water.
cooling water Water obtained from a source (cooling tower, river, pond) to which heat is rejected. This water flows through tubes in the absorber and the condenser.
corrosion inhibitor Chemical added to the absorbent solution to protect the steel components of the chiller from the corrosive action of the water and lithium bromide solution.
crystallization The process of the absorbent leaving the solution as a solid, when the solution is cooled below its saturation temperature.
dilute absorbent solution A mixture of refrigerant and absorbent that has a relatively high refrigerant content and low absorbent content.
equilibrium chart A graphical representation of the properties of lithium bromide solutions. Vapor pressure is plotted on the vertical axis, solution temperature on the horizontal axis, and concentration on the diagonal lines.
evaporator A component of the absorption refrigeration system where cool liquid refrigerant absorbs heat from water (from the building system), causing the refrigerant to boil.
expansion device A component of the absorption refrigeration system used to reduce the pressure and temperature of the refrigerant to desired evaporator conditions.
flash The process of liquid refrigerant being vaporized by a sudden reduction of pressure.
generator A component of the absorption refrigeration system in which refrigerant vapor boils and is separated from the absorbent solution as it absorbs heat from the primary heat source.
intermediate absorbent solution A mixture of refrigerant and absorbent that is a combination of dilute and concentrated solutions.
performance additive Chemical added to the absorbent solution to enhance the rate at which refrigerant vapor is absorbed by the lithium bromide solution, improving the performance of the cycle.
