自19世纪中期以来，机械通风一直被用作为建筑物提供可接受的室内空气条件的有效方法。传统上，机械通风系统是为室内吸烟的酒店场所通风的首选方法。机械通风系统的工作原理是将空气引入建筑物并通过建筑物移动空气，以达到与室外空气质量相当的室内空气质量。欧洲供暖与空调联合会- 指导方针4“通风和吸烟:减少建筑物中ETS的暴露”中的空调协会（REHVA）提供了为酒店场所和其他吸烟建筑物实现有效通风的最佳实践指南（REHVA 2004）。REHVA认识到这个话题对于室内空气质量和能源消耗极为重要。最近批准的欧盟（EN）EN/DIN标准15251“针对室内空气质量、热环境、照明和声学的建筑物能源性能设计和评估的室内环境输入参数”建议允许吸烟的建筑物空间的特定通风率（CEN）- EN/DIN标准15251）。在允许吸烟的酒店场所，最近有人提出了机械通风系统对室内空气质量影响的问题。我们回顾了有关有效机械通风和烟草烟雾的现有文献，发现很少有旨在确定通风对酒店场所烟草烟雾影响的研究实际测量和量化了通风参数。事实上，这些研究中的许多都没有测量和量化室内空气质量或烟草烟雾。 此外，尽管有一些研究测量并报告了通风、室内空气质量和环境烟草烟雾（ETS）参数，但这些研究中的大多数酒店场所都没有有效的通风系统。此外，一些研究似乎将空气过滤（清洁）和空调系统误分类为通风系统。在吸烟的酒店场所，缺乏数据来确定有效通风与烟草烟雾之间的关系。 为了获得关于这种关系的现场数据，对美国和英国的酒店场所进行了这些实地研究。这些实地研究的目的是评估美国和英国各种类型和配置的酒店场所机械通风系统的性能，以确定这些系统在允许吸烟的空间提供可接受的室内空气质量方面的有效性。 这些对两大洲六个酒店场所的实地研究包括对三家赌场、两家酒吧和一家餐厅的通风和室内空气质量测量。本文介绍了对通风和室内空气质量的测量，包括在六个场馆内的几个地点采样的环境烟草烟雾参数，以评估机械通风的有效性。室内空气质量测量包括二氧化碳、一氧化碳、总挥发性有机化合物、温度、相对湿度和可吸入悬浮颗粒物。 还对室外空气进行了测量，作为比较室外空气质量和室内空气质量的方法。现场研究的数据表明，机械通风是提供室内空气质量条件的有效手段，与允许吸烟的酒店场所的室外空气质量相当。单位:双引文:ASHRAE交易，第115卷，第。2、路易斯维尔2009

Mechanical ventilation has been used since the middle 19th century as an effective method of providing acceptable conditions of indoor air in buildings. Mechanical ventilation systems have traditionally been the method of choice by which to ventilate hospitality venues where smoking occurs indoors. Mechanical ventilation systems work by introducing air into and moving air through buildings to achieve indoor air quality that is comparable to outdoor air quality. The Federation of European Heating and Air-Conditioning Associations (REHVA) in Guideline 4 "Ventilation and smoking: Reducing the exposure to ETS in buildings" provides guidance on best practices to achieve effective ventilation for hospitality venues and other buildings where smoking occurs (REHVA 2004). REHVA recognizes this topic as extremely important in respect to indoor air quality and energy consumption. The recently approved European Union (EN) EN/DIN Standard 15251 "Indoor environmental input parameters for design and assessment of energy performance of buildings addressing indoor air quality, thermal environment, lighting and acoustics" recommends specific ventilation rates for spaces in buildings where smoking is allowed (CEN- EN/DIN Standard 15251). Questions have been recently raised about the effect of mechanical ventilation systems on indoor air quality in hospitality venues where smoking is allowed. We have reviewed the literature available about effective mechanical ventilation and tobacco smoke and have found that very few studies purporting to establish the effect of ventilation on tobacco smoke in hospitality venues have actually measured and quantified ventilation parameters. In fact, many of these studies have not measured and quantified indoor air quality or tobacco smoke. Further although there are a few studies that have measured and reported ventilation, indoor air quality and environmental tobacco smoke (ETS) parameters, most of the hospitality venues included in these studies do not have effective ventilation systems. In addition, some of the studies appear to have misclassified air filtration (cleaning) and air conditioning systems as ventilation systems.There is a dearth of data with which to determine the relationship between effective ventilation and tobacco smoke in hospitality venues where smoking occurs. These field studies of hospitality venues in the United States and the United Kingdom was undertaken in order to obtain field data on this relationship. The objectives of these field studies were to evaluate the performance of mechanical ventilation systems in various types and configurations of hospitality venues in both the United States and the United Kingdom to determine the effectiveness of these systems in providing acceptable indoor air quality in spaces where smoking is allowed. These field studies of six hospitality venues on two continents included ventilation and indoor air quality measurements of three casinos, two pubs and one restaurant.This paper presents measurements of ventilation and indoor air quality including environmental tobacco smoke parameters sampled in several locations within each of the six venues to assess the effectiveness of mechanical ventilation. The indoor air quality measurements included carbon dioxide, carbon monoxide, total volatile organic compounds, temperature, relative humidity and respirable suspended particles. Measurements were also taken in the outdoor air as a means of comparing outdoor air quality with the indoor air quality.The data from the field studies shows that mechanical ventilation is an effective means of providing indoor air quality conditions that are comparable to the outdoor air quality in hospitality venues where smoking is permitted.Units: Dual
