CAN/CSA C743-09 (R2019)

Scope

1.1
This Standard applies to factory-designed and prefabricated vapour-compression chillers that include one or more hermetic or external drive compressors.

1.2
The compressor types covered under this Standard include
(a) centrifugal;
(b) screw;
(c) scroll;
(d) reciprocating; and
(e) other types.

1.3
The condenser types covered under this Standard include
(a) water-cooled;
(b) air-cooled/evaporatively cooled; and
(c) air- or water-cooled heat reclaim. Packages can also be supplied without a condenser.

1.4
This Standard applies to
(a) factory-designed and prefabricated water-cooled absorption chiller/heater units;
(b) units that are
(i) single-effect indirect-fired by steam or hot water; and
(ii) double-effect, both indirect-fired by steam or hot water and direct-fired by oil, natural gas, or liquefied petroleum (LP) gas (water is the refrigerant and lithium bromide is the absorbent); and
(c) positive displacement chillers using fluids with secondary coolants (glycol or brine) for freeze protection and leaving brine temperatures greater than 0 °C (32°F).

1.5
This Standard does not apply to
(a) absorption chiller/heater units with air-cooled condensers; or
(b) applications employing heat pumping or exhaust gas firing.
