独立通风笼具两种送风方式的解析

Analysis of two air supply modes for individually ventilated cage systems

目的针对实验动物设施建设中主流应用的两种独立通风笼具(individually ventilated cage,IVC)系统送风方式的特点进行总结,分析其不同的适用性。方法根据典型案例,从安全可靠性、空间利用率、运行能耗、监控调节、初投资这五方面对两种送风方式的具体特点进行详细分析。结果针对每一对比项,比较得出了两种送风方式各自的优缺点。结论两种送风方式各具优势。送风方式A适用于较小规模的设施,适用于对笼盒参数需要分散、灵活调控的项目;送风方式B适用于中大型的设施。

Objective To summarize the characteristics of two main individually ventilated cage(IVC)air supply modes in the construction of laboratory animal facilities,and analyze their different uses.Methods According to typical cases,the specific characteristics of the two air supply modes were analyzed in detail by five aspects:safety and reliability,space utilization,operation energy consumption,monitoring and regulation and initial investment.Results For each comparison item,the advantages and disadvantages of the two air supply modes were compared.Conclusions The two method of air supply had their individual advantages.Air supply mode A is suitable for small-scale facilities and projects that require a decentralized and flexible control of cage parameters.Air supply mode B is suitable for medium-sized and large-scale facilities.
