前言这是CSA C823《住宅空间空调系统中空气处理器的性能》的第一版。 本标准规定了在一系列静压和速度控制设置下测量住宅空间空调系统中空气输送和空气处理器电能消耗的要求。根据这些测量结果，使用标准化的系统阻力曲线，为空气处理器的每个操作控制设置制定性能等级。还计算了年度电能消耗额定值。由于空气处理器的安装和使用方式不同，其实际性能和年用电量可能因额定值不同而不同。范围1。1本标准适用于住宅中央空间空调系统（如炉子、热泵、组合空气处理器和风机盘管）中用于供应和/或循环空调空气的管道空气处理器。 1.2本标准规定了确定空气输送和空气处理器电能消耗性能等级的试验程序和计算。它没有涉及空气处理器系统的热性能额定值。1.3本标准不适用于引风机、排气扇或热/能量回收通风机。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”用于表示一个选项或在标准范围内允许的选项。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）来定义其应用。1.5国际单位制给出的数值为本标准中的记录单位。括号中给出的值仅供参考和比较。

PrefaceThis is the first edition of CSA C823, Performance of air handlers in residential space conditioning systems. This Standard specifies requirements for measuring both the air delivery and the electrical energy consumption of air handlers in residential space conditioning systems over a range of static pressures and speed control settings. Based on those measurements, performance ratings are developed for air handlers for each of their operating control settings using a standardized system resistance curve. An annual electrical energy consumption rating is also calculated. The actual performance and annual electricity use of air handlers can vary from the ratings because of differences in how they are installed and used.Scope1.1This Standard applies to ducted air handler units that are used to supply and/or circulate conditioned air in residential central space conditioning systems such as furnaces, heat pumps, combination air handlers, and fan coils.1.2This Standard specifies the test procedure and calculations for determining performance ratings for the air delivery and electrical energy consumption of air handlers. It does not address thermal performance ratings for air handler systems.1.3This Standard does not apply to draft inducer fans, exhaust fans, or heat/energy recovery ventilators.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; 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. Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.1.5The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
