本次调查的目的是确定和量化已安装的备用燃气炉系统的低效性。对每种可能的低效源进行系统测量，确定现有装置的可能效率范围，定义良好装置的“可实现”效率，并指出实现可实现效率所需的修改。本报告描述了季节效率分析综合的单独测试结果，以及现有和新装置的标准建议。引文:研讨会，ASHRAE交易，第83卷，第一部分，伊利诺伊州芝加哥

The purpose of this investigation was to identify and quantify the inefficiencies of installedresidential gas furnace systems. The systematic measurement of each possible source of inefficiencyoutlines the probable range of efficiency of existing installations, defines the"attainable" efficiency of a good installation, and points out the modifications required toachieve the attainable efficiency.This report describes the results of the individual testing the analytical syntheses ofseasonal efficiencies, and the recommendations for standards for existing and new installations.
