This is the third edition of CSA C742, Energy performance of automatic icemakers and ice storage bins. It supersedes the previous editions, published in 1998 and 1994 under the title Performance of Automatic Ice-Makers and Ice Storage Bins.
This Standard applies to factory-made automatic icemakers with a capacity not exceeding 1814 kg/d, measured at standard rating conditions. These machines produce cube, flake, crushed, or fragmented ice in batches or in a continuous process. They are electrically operated and are designed for a 60 Hz operating current with nominal nameplate voltage.
This Standard applies to freestanding and integral factory-made manual-scoop-out ice storage bins.
This Standard specifies requirements and test procedures for energy and water consumption and storage effectiveness.
This Standard applies to
(a) self-contained icemakers where the ice-making mechanism and storage compartment are integrated in one cabinet; and
(b) split-system icemakers that have the ice-making mechanism and condensing unit in separate sections. Condensers can be air- or water-cooled.
This Standard does not apply to
(a) icemakers installed in
(i) household refrigerators;
(ii) refrigerator-freezers; or
(b) countertop models; or
(c) cold-plate drink dispensers.
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
