This Standard applies to factory-designed and prefabricated vapour-compression chillers, including one or more hermetic or external drive compressors. The compressor types include centrifugal, screw, scroll, reciprocating, or other types, and the condenser types include water-cooled and air-cooled/evaporatively cooled types, or the package can be supplied without a condenser. Also, air- or water-cooled heat reclaim condensers can be supplied.
This Standard applies to
a) factory-designed and prefabricated water-cooled absorption chiller/heater units;
b) single-effect indirect-fired by steam or hot water; and
c) double-effect, both indirect-fired by steam or hot water and direct-fired by oil, natural gas, or LP gas; water is the refrigerant and lithium bromide is the absorbent.
This Standard does not apply to absorption chiller/heater units with air- cooled condensers, nor does it apply to applications employing heat pumping or exhaust gas firing.
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
In CSA Standards, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Legends to equations and figures are considered requirements.
