在一个小型的办公型实验空间中，研究了一种通过有效利用能源来改善室内空气质量的通风方法。这些实验是用人体进行的。送风口和抽风口的位置在空间中是可交换的，初始室温和送风温度是可控制的。报告了在不同温度条件下通过向上通风提高通风效率和减少通风要求的可能性。结果表明，在向上通风的情况下，如果居住者是唯一的连续源，则通风需求可以减少到11左右。 每人8立方英尺（5.6升/秒），呼吸区内的二氧化碳浓度不超过1000 ppm，因为与传统混合系统相比，向上通风系统对室内二氧化碳含量的影响较小，因为通风率的变化导致室内二氧化碳含量的变化。供气温度不得高于室温，以保持呼吸区的CO2浓度较低。关键词:通风、换气率、效率、空气质量、室内、办公室、实验、空气供应、温度、二氧化碳、房间、内容物、室温、占用者引用:ASHRAE Trans。1992年，第98卷，第一部分，论文编号- 92-4-1723-729，8图。，2个标签。，裁判。

A ventilation method to attain an improved indoor air quality with effective use of energy was examined in a small, office-type experimental space. The experiments were carried out using human subjects. The positions of air supply and extract openings were exchangeable in the space, and initial room air temperature and supply air temperature were controlled. Reports the possibilities of ventilation efficiency improvement and lessening of ventilation requirements by upward ventilation at various temperature conditions. The results indicated that with upward ventilation, if the occupant is the only continuous source, the ventilation requirement could be lessened to about 11.8 cfm (5.6 L/s) per person without exceeding a CO2concentration of 1,000 ppm in the breathing zone because the change of room CO2content due to variation of the ventilation rate is influenced less by an upward ventilation system than by a traditional mixing system. The supply air temperature must not be higher than the room air temperature to keep the CO2concentration in the breathing zone low.KEYWORDS: ventilation, air change rate, efficiency, air quality, indoor, offices, experiment, air supply, temperature, carbon dioxide, rooms, content, room temperature, occupiers
