摘　　要：通常采用名义通风量指标描述房间整体的通风情况,然而实际室内环境多为非均匀环境,仅用名义通风量很难有效评价房间真实的通风效果。从实际通风效果的角度出发,定义名义通风量、有效通风量和局部通风量3类新风量指标,并通过算例说明3类指标的区别。建议采用有效风量代替名义风量用于评价房间的整体通风效果;而在评价局部区域通风效果时,采用局部纯净风量和局部通风量指标。The nominal ventilation rate are normally applied to evaluation of the overall ventilation effect. However, it is difficult to perform effective evaluation by using this index because of the nonuniform characteristics of indoor environment. Demonstrates three ventilation indices, i.e. the nominal ventilation rate, effective ventilation rate and local ventilation rate from the actual ventilation effect angle, and indicates their difference with a case study. Suggests that the effective ventilation rate, in place of nominal ventilation rate, be used to evaluate the overall ventilation effect while local net flow rate and local ventilation rate be used to evaluate the local ventilation effect.
