标准206提供了一种统一的测试方法，用于对在住宅应用中进行空间调节和水加热的多用途热泵的季节效率进行评级。本程序将过去的试验程序和美国能源部关于特殊设计设备的豁免合并为一个综合程序，涵盖所有现有和预期的多用途热泵。它包括六种不同的基本系统:单容量空气源、双容量空气源、可变容量空气源、单容量液体源、双容量液体源和可变容量液体源系统。购买本标准包括基于Web访问组合电器性能计算电子表格，以帮助计算程序（仅限I-P。需要Microsoft Excel）。

Standard 206 provides a uniform method of testing for rating the seasonal efficiency of multipurpose heat pumps that perform space conditioning and water heating in residential applications. This procedure pulls together past test procedures and U.S. Department of Energy waivers dealing with special design equipment into a single comprehensive procedure covering all existing and anticipated multipurpose heat pumps. It covers six different basic systems: single capacity air-source, dual capacity air source, variable capacity air-source, single capacity liquid source, dual capacity liquid-source, and variable capacity liquid-source systems.Purchase of this standard includes Web-based access to the Combined Appliance Performance Calculation Spreadsheet to assist in calculations for the procedure (I-P only. Requires Microsoft Excel).
