Question

Recommended Whole Building Mechanical Ventilation Rate: This value is the recommended whole building ventilation rate to be supplied on a continuous basis using a mechanical ventilation system. The recommended mechanical ventilation rate is based on 7.5 CFM per person (or number of bedrooms plus one – whichever is greater), plus 1 CFM per 100 square feet of floor area. This guideline assumes that in addition to the mechanical ventilation, natural infiltration is providing 2 CFM per 100 square feet of floor area.. For buildings where the estimated annual natural infiltration rate (based on the Blower Door test) is greater than 2 CFM per 100 square feet of floor area, the recommended mechanical ventilation rate is reduced to provide ventilation credit for excess infiltration. In these cases, the recommended mechanical ventilation rate is reduced by the following amount: 0.5 x (estimated annual natural infiltration rate (CFM) – 0.02 CFM x sq. ft. of floor area ) Notes on Ventilation Guidelines: • ASHRAE Standard 62.2 also contains requirements for local kitchen and bathroom mechanical exhaust systems. These local exhaust systems may be incorporated into a whole building ventilation strategy. Consult Standard 62.2 for more information on ventilation strategies and specific requirements and exceptions contained in the Standard.

Answer 1

建议所有建筑换气次数：这重要性是建议所有建筑通风换气次数是供应不断的基础来使用机械通风系统。建议次数为7.5CFM每人（许多单间加一-无论是哪一个较大的），加1CFM每地板面积的100平方米。这指导方针假设除通风之外，
自然参透是预备2 CFM每100平米。对于建筑物预计的每年自然侵润比率（以鼓风机门阀测试为基础）大于2CFM每平方米，建议次数减小于提供空气流通信任超过参透物。这些数据，建议次数减小到数量为：0.5（预计每年自然渗透率：CFM-0.02x平方）根据空气流通的指导方针:.美国采暖标准62.2并且包括当地居民厨房浴室机械的排气装置系统。这些据排除系统或许包含所有空气流通装置。商议标准取得进一步资讯信息在空气流通策略上和特殊要求与异常处理标准。
