本文讨论了一种新的基于送风CO2浓度的多区域暖通空调系统通风控制策略。根据ASHRAE标准62.1 2010，stagey在提供所需通风的同时，为降低暖通空调系统的能耗提供了一个很好的机会。该策略需要一个PI/或PID控制器以及位于主送风管道中的CO2传感器，通过调整室外空气挡板来控制送风浓度。它还包括一个控制算法，用于在适当的时间间隔内，使用实际区域气流速率动态重置CO2浓度设定点。 该策略通过在典型VAV系统调节的多区域办公楼上以及在不同美国地点下的仿真进行评估。结果表明，与ASHRAE标准62.1 2012程序中的设计占用率相比，通过实施拟议的策略可以获得显著的节约，这种节约主要取决于实际占用率和建筑位置。引用:ASHRAE Trans。，第118卷第。德克萨斯州圣安东尼奥2号

The paper discusses a new ventilation control strategy based on supply air CO2 concentration for multi-zone HVAC systems. The stagey offers a great opportunity to reduce energy consumption in HVAC systems while providing the required ventilation according to ASHRAE Standard 62.1 2010. The strategy requires a PI/ or PID controller along with a CO2 sensor located in the main supply air duct to control the supply air concentration by adjusting the outdoor air damper. It also includes a control algorithm to dynamically reset the CO2 concentration set point on a proper time interval basis and using the actual zone airflow rates. The strategy is evaluated by simulation on multi-zone office building conditioned by a typical VAV system and under various USA locations. The results show that significant savings could be obtained by implementing the proposed strategy as compared to the design-occupancy ASHRAE Standard 62.1 2012 procedure and this saving depends mainly on actual occupancy profile and building locations.
