范围1。1本标准规定了每小时额定容量高达21 mL/s（20 US gal/h）的自给式饮用水冷却器的能源性能要求。包括:（a）测量容量和能耗的程序，包括备用损耗；和（b）最高能耗水平。1.2本标准适用于以下机械式、热电式和其他电动饮用水冷却器，其设计用于冷却水，以便输送至本地或远程安装的分配装置:（a）加压式；（b） 使用点（POU）类型；（c） 远程类型；（d）瓶型。本标准也适用于通过冷藏室或加热饮用水或两者兼而有之的方式提供额外公用设施的装置。 1.3本标准不适用于拟用于中央循环型系统的饮用水冷却器（a）；或（b）采用远程型（分体式）冷凝装置。1.4在CSA标准中，“应”用于表示要求，即用户有义务满足的条款，以符合标准；“应该”用于表示建议或建议但不需要的建议；“可”用于表示一种选择或在标准范围内允许的选择；“can”用来表示可能性或能力。注释随附条款不包括要求或替代要求； 随附条款的注释的目的是将解释性或信息性材料与文本分开。表和图的注释被视为表或图的一部分，可以作为要求编写。附件被指定为规范性（强制性）或信息性（非强制性）以定义其应用。1.5以SI（公制）单位给出的值为标准值。括号中给出的值仅供参考。

Scope1.1This 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.1.2This 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.1.3This 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.1.4In 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.1.5The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
