View Access for this document is only available for viewers in Canada
This Standard provides definitions, classifications, and a method for determining specific daily energy consumption (SDEC) values and states minimum energy efficiency requirements for refrigerated display cabinets.
This Standard applies to refrigerated display cabinets, as described in Clause 4 and shown in Figures 1 to 7, that are intended for displaying and merchandising food products, including canned and bottled beverages, ice intended for human consumption, and other perishable merchandise (e.g., cut flowers).
This Standard applies to (a) refrigerated display cabinets (as described in Clause 1.2), except as specified in Clause 1.4, provided that the cabinets are designed to work with a remotely located, electrically driven, vapour-compression-type refrigeration system charged with one of the refrigerants listed in Group A1 of CSA B52, and with cabinets having a rectangular footprint; and (b) cabinets in the shape, size, and configuration as shipped from the manufacturer.
This Standard does not apply to
(a) self-contained cabinets as covered by CAN/CSA-C827;
(b) refrigerated cabinets that are designed to form the front wall of a refrigerated storage room and where the air space of the cabinet is not separated from the air space of the storage room;
(c) mitred transitional cabinet fillers (wedges) used as corner sections between two refrigerated cabinets of similar cross-sections;
(d) trapezoid-shaped end cabinets;
(e) combination merchandisers;
(f) custom-designed refrigerated display cabinets; and
(g) refrigerated vending machines as covered by CAN/CSA-C804.
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.
