1973年10月至1974年初春的能源危机使人们意识到需要改进燃气空间加热器的性能并节约能源。从那时起，人们提供了新的备用加热设备和安装在现有设备上的改造项目，并声称这些设备具有节能潜力。1976年夏天，美国燃气协会（AGA）组织了备用加热效率改进计划（SHIP），以现场测试新的空间加热装置和安装在现有设备上的改造项目的节能潜力。本文将展示如何利用SHIP中开发的测试方法对安装在燃气空间供暖设备上的通风挡板进行额外的现场测试和性能评估。引文:ASHRAE Transactions，1983年，第89卷，pt。新泽西州大西洋城1B号

The energy crisis of October 1973 through the early spring of 1974 created an awareness of the need to improve the performance of gas-fired space heaters and conserve energy. Since then new spare heating equipment and retrofit items for installation on existing equipment have been offered along with claims of their energy-saving potential. The American Gas Association (AGA) Spare Heating Efficiency Improvement Program (SHEIP) was organized in the summer of 1976 to field test the energy saving potential of new space heating units and retrofit items installed on existing equipment. This paper will show how the test method developed in the SHEIP was utilized to conduct additional field tests and performance evaluations of vent dampers installed on gas-fired space heating equipment.
