本案例研究是一个实际操作系统，其中可变风量（VAV）、直接数字控制（DDC）和烟雾管理已应用于医院护理部。包括对设计标准、设计备选方案、实际性能、室外空气和总换气率、房间增压、体积流量跟踪、可靠性和能量的讨论。与定容和气动控制系统相比，VAV和DDC系统实际上具有一些性能和可靠性优势，尤其是在提供了备用装置和策略的情况下。在案例研究中，与定容系统相比，可变风量系统具有显著的能源优势。单位:双引文:研讨会，ASHRAE交易，1988年，第94卷，pt。德克萨斯州达拉斯1号

The case study is an actual operating system where Variable Air Volume (VAV), Direct Digital Control (DDC), and Smoke Management have been applied to a hospital nursing wing. A discussion of design criteria, design alternatives, actual performance, outdoor air and total air change rates, room pressurization, volumetric flow rate tracking, reliability, and energy is included.VAV and DDC systems actually have some performance and reliability advantages in comparison ’to constant volume and pneumatic control systems, particularly when backup devices and strategies have been provided. In the case study there is a significant energy advantage to variable air volume systems in comparison to constant volume systems.Units: Dual
