实验室研究设施使用巨大的气流来确保烟雾安全地排出实验室环境，这通常会导致高能耗和高昂的公用事业费用。随着我们进入90年代的十年，节能和降低这些设施的运营成本通常被视为一种权衡，需要考虑适当的室内空气质量。介绍了一个案例研究，介绍了在位于美国中西部的一个大型现有工业研究设施中，整合现代技术和知识以改善通风和降低能耗的努力。利用Kepner-Tregoe决策方法，考虑并比较了几种改造方案。 基于这种比较，在校园的两栋建筑中启动了可变风量转换项目。介绍了导致设计的研究和分析（包括转换为VAV的年度能源成本和节约），以及一些相关设计细节的讨论。关键词:变风量空调、现代化、工业、研究、实验室、能耗、节能、案例研究、通风、美国、比较、成本、经济性、设计、空气质量、排气罩、空调、定容空调。引用:研讨会，ASHRAE Trans。，1993年，第99卷，第2部分，论文编号DE-93-1-1429-439，图7，表2，参考文献。

A laboratory research facility uses tremendous air flow to ensure that fumes are safely exhausted out of the lab environment, which usually results in high energy use and steep utility bills. As we enter the decade of the '90s, energy conservation and lower operating costs in these facilities are often perceived as a trade-off with concerns for proper indoor air quality. Presents a case study of efforts to incorporate modern technology and knowledge to both improve ventilation and reduce energy consumption at a large existing industrial research facility located in the midwestern United States. Several retrofit options were considered and compared utilising a Kepner-Tregoe decision-making methodology. Based on this comparison, variable-air-volume conversion projects have been initiated in two buildings on the campus. A description of the study and analysis leading to the design (including annual energy cost and savings for the conversion to VAV) as well as a discussion of some pertinent design details are presented.KEYWORDS: variable volume air conditioning, modernising, industrial, research, laboratories, energy consumption, energy conservation, case studies, ventilation, USA, comparing, costs, economics, designing, air quality, exhaust hoods, air conditioning, constant volume air conditioning.
