如果要达到可接受的性能，医院手术室必须满足任何室内环境中最复杂的控制要求之一。本研究项目的总体目标是确定和证明控制策略，以减少能源需求，同时对手术室内的环境质量产生有害影响。这一目标是通过广泛的文献检索、数学和生物物理模型的开发，以及对两个具有不同系统性能特征的现有手术室（OR 1和OR 5）中获得的数据进行分析来实现的。OR 1设计于1961年，通过高侧壁格栅和低侧壁回风调节器，每小时供应12次100%的室外空气（ACH）。 OR 5于1975年设计，通过天花板扩散器和墙上的中高回风调节器，提供25 ACH，其中20%为室外空气。ORs 1和ORs 5实际分别提供12 ACH和17 ACH，ORs 5至少提供17%的室外空气。在模拟手术的占用条件下，两间手术室在五个尺寸范围内的总颗粒物沉降率没有检测到统计上的显著差异，但在再循环空气系统中观察到活性颗粒物沉降量减少的趋势。虽然在手术室中测得的浓度和沉降率低于数学模型和生物物理模型中的预测值，但模式相似。通过数学和生物物理模型确定了一种控制策略，该策略将减少较大颗粒的沉降，同时将运行中的总空气交换率从17 ACH降至12 ACH。 单位:SICitation:ASHRAE Transactions，1986年，第92卷，pt。2A，波特兰，或

Hospital operating roans must meet one of the most complex sets of control requirements of any indoor environment if acceptable performance is to be achieved. The overall objective of this research project was to identify and demonstrate control strategies that could reduce energy requirements while riot producing deleterious effects on the environmental quality within the operating room.The objective was achieved through an extensive literature search, through the development of mathematical and biophysical models, and through analysis of data obtained in two existing operating rooms (OR 1 and OR 5) with different system performance characteristics. OR 1 was designed in 1961 to supply 12 air changes per hour (ACH) of 100% outdoor air through high sidewall grilles and low sidewall return registers. OR 5 was designed in 1975 to supply 25 ACH, 20% of which was outdoor air, through ceiling diffusers and mid-height return registers on the wall. The ORs 1 and 5 actually delivered 12 ACH and 17 ACH, respectively, and OR 5 provided a minimum of 17% outdoor air.No statistically significant differences in settling rates of total particulates in five size ranges were detected between the two operating rooms during occupied conditions that simulated surgery, but a trend toward less settling of viable particles was observed in the recirculated air systems. While the magnitude of the concentration and settling rates measured in operating rooms were less than those predicted in the mathematical model and measured in the biophysical model, the patterns were similar.A control strategy was identified through mathematical and biophysical models that would result in less settling of the larger particles while reducing the total air exchange rate in the operating roans from 17 ACH to 12 ACH.Units: SI
