为满足ANSI/ASHRAE标准62-1989修订版提出的受控通风要求，重要的是选择正确类型的风门，以准确提供并保持混合空气室所需的空气量。对制造的空气处理机组中常用的风门进行的测试表明，混合风门会严重影响进气通风和空调系统的整体性能。因此，选择正确的叶片动作可以提高可变性，以获得正确的通风风量。本文侧重于测试，并建议在制造的空气处理机组上使用叶片动作。单位:I-P沉淀: 研讨会，ASHRAE交易，1998年，第104卷，第2部分，多伦多

To meet the controlled ventilation requirements proposed for the revision of ANSI/ASHRAE Standard 62-1989, it is important that the correct type of damper be selected to accurately provide and maintain the volume of air required in the mixed air plenum. Testing of the dampers commonly used in manufactured air-handling units has shown that the mixed air dampers can drastically affect the intake ventilation air and the overall performance of the air-conditioning system. Therefore, selecting the correct blade action can improve the variability to achieve the correct ventilation air quantity. This paper focuses on testing and recommends the blade action to be used on manufactured air-handling units.Units: I-P
