Glossary
absorbent A substance used to absorb refrigerant and transport it from the
absorber A component of the absorption refrigeration system where refrigerant vapor is absorbed by the absorbent solution and rejects heat to cooling water.
ARI Air Conditioning & Refrigeration Institute.
ARI Standard 560 A publication, titled “Absorption Water Chilling and Water Heating Packages,” used to promote consistent rating methods for many types and sizes of absorption water chillers, using water as the refrigerant and lithium bromide as the absorbent. It covers
ASHRAE American Society of Heating, Refrigerating and
ASHRAE Standard 15 A publication, titled “Safety Code for Mechanical Refrigeration,” that specifies safe design, construction, installation, and operation of refrigerating systems.
auxiliary heating bundle A separate heat exchanger added to a
chilled water The cold water produced by the chiller (flowing through the tubes in the evaporator) and pumped to the
coefficient of performance (COP) A dimensionless ratio used to express the efficiency of a refrigeration machine. For an absorption water chiller, it is defined as the ratio of evaporator cooling capacity divided by the heat energy required by the generator, excluding the electrical energy needed to operate the pumps, purge, and controls. A higher COP designates a higher efficiency.
compressor A mechanical device used in the
concentrated absorbent solution A mixture of refrigerant and absorbent that has a relatively low refrigerant content and high absorbent content.
