在两个供暖季节，对寒冷气候下的家用电器进行了被动燃烧空气供应的实验研究。在这段时间里，在两座测试建筑中收集了8000多小时的每小时空气交换率数据。检查通风口的性能，其尺寸和位置符合统一机械规范。检查燃烧空气供应机械系统的使用。根据规范确定尺寸的被动燃烧空气供应系统平均可供应足够的室外空气，以满足燃烧和空间调节要求。在极端环境条件下（低温和高风速），观察到接近设计速率300%的气流。实验评估了通过减少排气横截面积来降低流速。平均流速略有下降，但流速的极端值仍与全流量相当- 尺寸大小的通风口，表明在环境极端情况下，空气供应过剩的问题无法通过减少通风口面积来解决，而在条件温和时，不存在供应不足的危险。观察到，使用风扇机械供应燃烧空气始终能提供足够的空气。风扇系统的正确设计将确保房间不受系统加压，但能提供足够的空气。使用机械系统供应燃烧空气意味着空间调节和燃烧空气必须分开。关键词:1997年，燃烧空气，被动，通风，换气率，建筑物，性能，通风口，机械通风，室外空气，空气流量，寒冷地区，实验，住房，比较，测量引文:研讨会，ASHRAE Trans。1997年，第103卷，第一部分

An experimental study dealing with the passive supply of combustion air for appliances located in cold climates was carried out over two heating seasons. During that period more than 8,000 hours of hourly air exchange rates data were gathered in two test buildings. Examines the performance of vents sized and located in accordance with the Uniform Mechanical Code. Examines the use of a mechanical system for the supply of combustion air. Passive combustion air supply systems sized according to codes can, on average supply sufficient outdoor air to meet the combustion and space-conditioning requirements. Air flows of nearly 300% of the design rates were observed under environmental extremes - low temperature and high wind speed. Flow rate reduction through a reduction in vent cross-sectional area was experimentally evaluated. There was a small reduction in average flow rate, but the extremes in flow remained comparable to the full-sized vents, indicating that the problems of oversupply of air during environmental extremes cannot be solved through a reduction in vent area without the danger of inadequate supply when conditions are mild. Mechanical supply of the combustion air using a fan was observed to always supply adequate amounts of air. Proper design of the fan system will ensure that the room is not pressurised by the system but that adequate air will be supplied. The use of a mechanical system for the supply of combustion air means that space-conditioning and combustion air must be necessarily separated.KEYWORDS: year 1997, Combustion air, passive, ventilation, air change rate, buildings, performance, vents, mechanical ventilation, outdoor air, air flow rate, cold regions, experiment, housing, comparing, measuring
