Energy performance of drinking water coolers

Scope

1.1
This Standard specifies energy performance requirements for self-contained drinking water coolers having an hourly rated capacity of up to 21 mL/s (20 US gal/h). Included are:

(a) procedures for measuring capacity and energy consumption, including standby losses; and

(b) maximum energy consumption levels.

1.2
This Standard applies to the following mechanical, thermoelectric, and other electrically operated drinking water coolers that are designed to cool water for delivery to either locally or remotely installed dispensing means:

(a) pressurized type;

(b) point-of-use (POU) type;

(c) remote type; and

(d) bottle type. This Standard also applies to units that provide additional utility by means of a refrigerated compartment or a means of heating potable water, or both.

1.3
This Standard does not apply to drinking water coolers (a) intended for use on central circulating-type systems; or (b) employing remote-type (split-system) condensing units.

1.4
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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. 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. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.5
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
