介绍了作为ASHRAE RP-626一部分开发的新ASHRAE冷负荷和热负荷计算手册，重点介绍了新技术和数据。手册中的许多新材料都基于ASHRAE最近的研究，比如RP-472。对文献进行了全面审查，以确保手册中的所有数据都是最新的。新手册涵盖了三种负荷计算方法:传递函数法（TFM）、冷负荷温差/太阳能冷负荷/冷负荷系数法（CLTD/SCL/CLF）和总等效温差/时间平均法（TETD/TA）。CLTD/SCL/CLF方法是CLTD/CLF方法的修订版。这些修订在配套文件中进行了描述。该手册的一个重要新特点是在软盘上包含了TFM和CLTD/SCL/CLF方法的电子表格。 此外，为便于使用，手册已重新组织。关键词:冷负荷，热负荷，计算，综述。引文:1993年阿什雷交易会，第99卷，pt。1.

Describes the new ASHRAE Cooling and Heating Load Calculation Manual, developed as part of ASHRAE RP-626, with emphasis placed on new techniques and data. Much of the new material in the manual is based on recent ASHRAE research, such as RP-472. A comprehensive review of the literature was made to ensure that all data in the manual were the latest available. Three load calculation methods are covered by the new manual - the transfer function method (TFM), the cooling load temperature difference/solar cooling load/cooling load factor (CLTD/SCL/CLF) method, and the total equivalent temperature difference/time averaging (TETD/TA) method. The CLTD/SCL/CLF method is a revised version of the CLTD/CLF method. These revisions are described in a companion paper. A significant new feature of the manual is the inclusion of electronic tables on diskette for both the TFM and the CLTD/SCL/CLF methods. In addition, the manual has been reorganised for easier use.KEYWORDS: cooling load, heat load, calculating, reviews.
