调试过程的一个基本目标是确保HVAC系统按预期运行。特别是，暖通空调系统不仅要为建筑物内的居住者提供足够的通风，还要对占用的空间实现足够的增压，以防止未经调节的空气渗入。评估这些区域暖通空调系统性能的一种技术是，在建筑物和暖通空调系统的选定位置，对二氧化碳、一氧化碳和露点进行连续、多点监测。通过对这些参数的多点连续监测提供的具体性能评估包括确定输送给乘客用于通风的室外空气量，评估提供给给定空气处理机组（AHU）服务的不同位置的通风量的均匀性，评估系统运行的充分性，以彻底清除前一天占用的建筑物夜间空气污染物，确定无条件空气渗入占用空间，确定建筑物排气的大小和再吸入频率，以及确定从附近交通中引入车辆尾气的数量和频率。 本文介绍并讨论了所有这些绩效评估的具体例子。此外，这些持续的系统性能评估不仅可以确定问题的存在，还可以评估缓解措施的有效性，以纠正和消除这些问题。因此，对这些参数进行连续、多点监测，可以在建筑物的整个使用寿命内，从最初使用到改善室内空气质量（IAQ）。单元:非引文:研讨会，ASHRAE交易，第105卷，第。1.

One basic goal of the commissioning process is to make sure that the HVAC system is functioning as intended. In particular, it is intended that the HVAC system not only provide adequate ventilation for the building occupants but also achieve adequate pressurization of the occupied spaces to prevent the infiltration of unconditioned air. One technique for evaluating the performance of the HVAC system in these areas is to use continual, multipoint monitoring of carbon dioxide, carbon monoxide, and dew point at selected locations in the building and the HVAC system. Specific performance evaluations provided by multipoint continual monitoring of these parameters include a determination of the amount of outdoor air delivered to the occupants for ventilation, an evaluation of the uniformity of the amount of ventilation provided to the different locations served by a given air-handling unit (AHU), an evaluation of the adequacy of the system operation in completely purging the building overnight of air contaminants from the previous day's occupancy, the identification of the infiltration of unconditioned air into occupied spaces, the identification of the magnitude and frequency of reentrainment of building exhaust, and the identification of the magnitude and frequency of the introduction of vehicle exhaust from nearby traffic. Specific examples of all of these performance evaluations are presented and discussed in this paper. In addition, these ongoing evaluations of system performance can not only identify the presence of problems but can also evaluate the effectiveness of mitigation efforts to correct and eliminate these problems. The use of continual, multipoint monitoring of these parameters, therefore, can yield improved indoor air quality (IAQ) in buildings from initial occupancy throughout their useful life.Units: None
