提出了一种基于测量的送风和回风中二氧化碳（CO2）浓度来确定通风控制动态分区占用率的新方法。提议的瞬态方法的核心论点是，根据当前提议的BSR/ASHRAE标准62-1989R，仅基于占用率的固定CO2阈值是不可能的。相反，必须知道实际的动态入住人数，因为通风要求由建筑构件和入住构件两部分组成。其结果是，二氧化碳阈值必须随着入住率的变化而不断变化。将混合办公和会议室的模拟结果作为比较拟议临时占用率的基础- 基于二氧化碳的通风与其他两种公认的方法:基于二氧化碳的通风和恒定气流通风。仿真结果表明，由瞬态方程计算出的占用率与实际占用率精确一致，滞后时间等于测量扫描间隔。通过精确的占用信息，机械系统可以提供标准要求的抽气通风气流。从通风的角度来看，基于瞬时占用率的通风，没有能量损失。此外，该方案还可用于实时在线通风控制和系统优化。单位:双关键词:1997年，二氧化碳，测量，通风，控制，占用，办公室，会议空间，比较，需求控制通风: 研讨会，ASHRAE交易，第103卷，第2部分，波士顿1997年

Proposes a new method to determine the dynamic zonal occupancy for ventilation control based upon measured carbon dioxide (CO2) concentrations in the supply and return air. The central thesis of the proposed transient method is that a fixed CO2 threshold based upon occupancy alone is not possible under current proposed BSR/ASHRAE Standard 62-1989R. Rather, the actual dynamic occupancy head count must be known since the ventilation requirements consist of two parts-the building component and the occupancy component. The result is that the CO2 threshold must constantly be changed in time with occupancy. Employs simulation results for well-mixed office and conference rooms as the basis for comparison of the proposed transient occupancy-based ventilation with two other accepted methods: the CO2-based ventilation and the constant air flow ventilation. The simulation results show that calculated occupancy from the transient equation follows the actual occupancy precisely with a time lag equal to the measurement scan interval. With precise occupancy information, the mechanical system can provide the extract ventilation air flow required by standards. From a ventilation perspective, the transient occupancy-based ventilation-and without an energy penalty. Furthermore, this scheme is useful for real-time on-line ventilation control and system optimisation.Units: DualKEYWORDS: year 1997, Carbon dioxide, measuring, ventilation, controls, occupancy, offices, conference spaces, comparing, demand controlled ventilation
