112 TRG-TRC016-EN
absorbent A substance used to absorb refrigerant and transport it from the
low-pressure to the high-pressure side of the absorption refrigeration cycle.
In absorption water chillers, the absorbent is commonly lithium bromide.
absorber A component of the absorption refrigeration cycle in which
refrigerant vapor is absorbed by the absorbent solution and rejects heat to
cooling water.
air-cooled condenser A type of condenser in which refrigerant flows through
the tubes and rejects heat to air that is drawn across the tubes.
airside economizer A method of free cooling that involves using cooler
outdoor air for cooling instead of recirculating warmer indoor air.
ARI Air-Conditioning and Refrigeration Institute
ARI Standard 550/590 A publication titled Standard for Water Chilling
Packages Using the Vapor-Compression Cycle that promotes consistent rating
and testing methods for all types and sizes of water chillers. It covers factory-
designed, prefabricated water chillers, both air-cooled and water-cooled, using
the vapor-compression refrigeration cycle.
ARI Standard 560 A publication titled Absorption Water Chilling and Water
Heating Packages that promotes consistent rating methods for many types and
sizes of absorption water chillers in which water is the refrigerant and lithium
bromide is the absorbent. It covers single-effect chillers operating on steam or a
hot fluid; indirect-fired double-effect chillers operating on steam or a hot fluid;
and direct-fired double-effect chillers operating on natural gas, oil, or liquid
petroleum (LP).
ASHRAE American Society of Heating, Refrigerating and Air-Conditioning
Engineers
ASHRAE Guideline 3 A publication titled Reducing Emission of Halogenated
Refrigerants in Refrigeration and Air Conditioning Equipment and Systems that
includes a recommended list of data points to be logged daily for each water
chiller.
ASHRAE Standard 15 A publication titled Safety Code for Mechanical
Refrigeration that specifies safe design, construction, installation, and operation
of refrigerating systems.
ASHRAE/IESNA Standard 90.1 A publication titled Energy Standard for
Buildings, Except Low-Rise Residential Buildings that provides minimum
requirements for the energy-efficient design of buildings (except low-rise
residential buildings), including the HVAC system.
centrifugal compressor A type of compressor that uses centrifugal force,
generated by a rotating impeller, to compress the refrigerant vapor.
