本文件旨在制定适用于大多数系统的空调设计指南，而不是任何特定系统的具体设计。设备的操作条件和特性将决定任何成功系统的设计；由于这些特性和条件在不同的应用程序中差异很大，因此设计者应确定在遇到的条件下预期达到的目标。为了确定鼓风机、冷凝器风扇、冷凝器盘管、蒸发器盘管、过滤器、压缩机等项目的容量，需要遵守以下几段中概述的一些指南。

The purpose of this document is to establish air-conditioning design guidelines that will apply to most systems rather than the specific design of any particular system. Operating conditions and characteristics of the equipment will determine the design of any successful system; since these characteristics and conditions vary greatly from one application to another, the designer shall determine the goals expected to be reached under the conditions encountered. To determine the capacity of such items as blowers, condenser fans, condenser coils, evaporator coils, filters, compressors, etc., will require the adherence to several guidelines, some of which are outlined in the following paragraphs.
