摘要

ASHRAE RP-1747 是一种基于二氧化碳的按需控制通风(DCV)方法,它使用微调和响应逻辑来根据区域的通风要求动态调整变风量(VAV)末端设备的最小风量设定点。虽然模拟结果和实验室测试估计了与传统通风相比,RP-1747 对供暖、通风和空调系统的影响,但迄今为止,RP-1747 在有人居住的实际建筑物中的应用还很有限。本文介绍了 RP-1747 DCV 在一栋机构办公楼中的实际应用情况,该系统采用监督控制方法,历时八个月。在实施过程中,还开发并在案例研究建筑中采用了一种补充温度调节方法。对运行顺序的这些改变,以及对实施过程中发现的其他次优运行顺序的修正,分别减少了 36 ± 2 % 和 2 ± 6 % 的供热和制冷能耗,同时提高了案例研究中的人均通风率。研究结果旨在为有关这种新兴 DCV 方法的文献做出贡献,并为其在实际应用中的益处以及与其他控制逻辑的交互作用提供轶事证据,同时还展示了在实施复杂过程控制功能时进行监督控制的益处。

Implementation of next-generation occupant-centric sequences of operation in an office building using supervisory control
ASHRAE RP-1747 is a CO2-based demand-controlled ventilation (DCV) approach which uses trim and respond logic to dynamically adjust variable air volume (VAV) terminal units’ minimum airflow setpoints based on zones’ ventilation requirements. While simulation results and laboratory testing have estimated the impact on heating, ventilation, and air conditioning (HVAC) systems compared to traditional ventilation, there have been limited applications of RP-1747 in occupied, real-world buildings to date. This paper introduces a real-world implementation of RP-1747 DCV in an institutional office building over an eight-month period, using a supervisory control approach. During this implementation, a complementary temperature setback approach was also developed and employed in the case study building. These changes to the sequences of operation, as well as corrections to other sub-optimal sequences of operation discovered during implementation, resulted in a 36 ± 2 % and 2 ± 6 % reduction in heating and cooling energy use, respectively, while improving per person ventilation rates in the case study. The results aim to contribute to the body of literature on this emerging DCV approach and provide anecdotal evidence of its benefits and interactions with other control logic in a real-world application, while also demonstrating the benefits of supervisory control when implementing complex process control functions.
