根据ASHRAE标准62-1989的通风要求，有几种技术可以测量和控制VAV系统的最小室外进气率。然而，缺乏评估每种技术的准确性和易用性的指南。在本项目中，进行了理论和实验分析，以评估用于测量和控制变风量系统中最小室外进气率的几种技术。这项研究的结果将用于制定一套指南，供暖通空调系统设计师和建筑运营商使用，以确保VAV系统提供最低的室外进气率。

Several techniques exist to measure and control minimum outdoor air intake rates for VAV systems in accordance with the ventilation requirements of ASHRAE Standard 62-1989. However, guidelines are lacking to assess the accuracy and ease of implementation of each of these techniques. In this project, theoretical and experimental analyses are performed to evaluate several techniques for measuring and controlling minimum outdoor air intake rates in VAV systems. The findings of this research will be used to develop a set of guidelines intended for use by HVAC system designers and building operators to ensure that minimum outdoor air intake rates are provided by VAV systems.
