In this paper, the types and performance of range hoods commonly used in China are collected. In order to keep the mass concentration of indoor harmful gases ( CO and CO2 as representatives) meeting Indoor Air Quality Standard after removing them, authors propose a selection method of rang hoods and develop an optimal selection software based on the programming technology of ADO on the VC + + 6. 0 platform through the research and analysis of the air volume and residual pressure of a rang hood. The software can help users to select a range hood reasonably according to a specific kitchen circumstances, and it is intuitive, friendly, and simple. In conclusion, to choose a suitable range hood for a specific kitchen, the primary factors considered include the air volume and residual pressure, the other indices of the price, motor power, noise level are in the secondary place.%目的 开发吸油烟机优化选型软件,提供专业、有效、快捷并且节能环保的吸油烟机选型方法.方法 统计全国目前常用吸油烟机的种类和性能,以厨房内有害气体排除后,剩余有害气体(代表物CO和CO2)的质量浓度值符合室内空气质量标准,对现有吸油烟机的选型提出方法.通过对风量和余压的研究与分析,基于VC++6.0平台,运用ADO技术编制吸油烟机的优化选型软件.结果 编制的优化选型软件能够针对厨房具体情况选择较适合的吸油烟机,且具有直观性、友好性及易操作等优点.结论 为特定厨房选择较适合吸油烟机应先综合风量和余压进行选型,再按价格、输入功率、噪声等指标进行选型比较合理.
