Operating room (OR) is an indispensable department in a hospital, while its ventilation system is an important engineering solution to ensure safety for surgical procedures. Suitable ventilation system in the OR should be defined as using the minimum energy consumption and lifecycle cost to meet both the requirements of clean air for safe surgeries and comfort for occupants. Therefore, this study aims to develop a flexible evaluation framework on the suitability evaluation for ventilation system performance in ORs from a holistic view instead of one aspect only. To achieve the objective, we adopted analytic hierarchy process (AHP) and fuzzy comprehensive evaluation (FCE) methods and conducted suitability evaluation for two ORs with laminar airflow (LAF) and mixing ventilation (MV) system in St. Olavs Hospital, Norway. The evaluation includes seven indexes under three main aspects: ventilation effectiveness, energy consumption and users’ satisfaction. The comprehensive evaluation results are obtained through site measurements during mock surgeries, data collection and calculation as well as the questionnaire survey. Due to the unsatisfactory performance in energy consumption and thermal comfort indexes, the evaluation result of the suitability performance of the case OR with MV system was “unsuitable” while the one with LAF system was “suitable”, which reflects the situation that the energy consumption and thermal environment are sacrificed, although a clean and safe operation environment is guaranteed. The evaluation can provide basis for the commissioning of the ventilation system in the ORs of St. Olavs Hospital and provoke thinking of the ventilation system design and operation in the future.
手术室（OR）是医院必不可少的部门，而其通风系统是确保手术过程安全的重要工程解决方案。手术室中合适的通风系统应定义为使用最低能耗和生命周期成本，以满足安全手术所需的清洁空气和乘员舒适度的要求。因此，本研究旨在从整体的角度而不是仅仅从一个角度来开发一种灵活的评估框架，以评估手术室中通风系统的性能。为实现这一目标，我们采用了层次分析法（AHP）和模糊综合评估（FCE）方法，并对挪威圣奥拉夫医院的两个具有层流（LAF）和混合通气（MV）系统的手术室进行了适合性评估。该评估包括三个主要方面的七个指标：通风效率，能耗和用户满意度。综合评估结果是通过在模拟手术过程中进行现场测量，数据收集和计算以及问卷调查获得的。由于能耗和热舒适性指标均不令人满意，因此与OR MV系统相适应的性能评估结果为“不合适”，而与LAF系统相适应的情况为“适合”，反映了能耗的情况。尽管保证了清洁安全的运行环境，但仍牺牲了热环境。该评估可以为在St. OR的通风系统的调试提供依据。
