本文基于ASHRAE研究项目RP-1083的研究结果。这项研究的重点是测量室内试验游泳池的氯基池水处理、过滤和化学处理产生的消毒副产物（DBP）的尾气，为机械系统设计师提供改善空气质量的规范指南。使用市售产品分析机械除湿（MDH）系统的水性出水中的氯仿（三卤甲烷或THM）、氯胺和pH值。使用标准NIOSH和OSHA分析方法，通过气相色谱法测定泳池蒸汽含量和成分，包括使用公布方法进行的初步三氯化氮（三氯胺或TCA）测量。 根据观察，这项研究证实并强调了三氯化氮是引起最大刺激的蒸汽（气体），而含有TCA的泳池空气在长期接触下基本上是有毒的。采用顶层通风和再循环率进行的测试证实了理解亨利定律和TCA物理特性的必要性。当与甲板（地面）通风结合使用时，在ASHRAE的当前通风率（0.5 cfm/ft2）下的低排气运动可以成功地将这种比空气重的TCA气体维持在室内空间的低水平。单位:I-PCitation:ASHRAE Transactions，第115卷，pt。2、路易斯维尔2009

This paper is based on findings resulting from ASHRAE Research Project RP-1083.This research focuses on measuring the off-gassing of disinfection by-products (DBP’s) from chlorine-based pool water treatment, filtration and chemistry of an indoor test swimming pool, to provide the Mechanical System Designer with specification guidelines for improved air quality. Aqueous derived effluent from the mechanical dehumidification (MDH) system is analyzed for chloroform (a trihalomethane or THM), chloramines and pH using commercially available products. Pool vapor content and composition are determined by gas chromatography using standard NIOSH and OSHA analytical methods and includes preliminary nitrogen trichloride (trichloramine or TCA) measurement using published methods. Based on observation, this research confirms and highlights that nitrogen trichloride is the vapor (gas) that causes the most irritation and pool air containing TCA is essentially toxic over long term exposure. Tests conducted with top level ventilation and re-circulation rates confirmed the need to understand Henry’s Law and the physical properties of TCA. When used in conjunction with deck (ground) level ventilation, low exhaust air movement at ASHRAE’s current ventilation rate (0.5 cfm/ft2) can be successful in maintaining this heavier than air TCA gas at low levels within the indoor space.Units: I-P
