某二级生物安全实验室变风量空调系统设计
Variable air volume air conditioning system design for a second-level biosafety laboratory
摘要：
本文介绍了设置B2型生物安全柜的二级生物安全实验室常用的2种变风量模式。结合北方城市某实验室项目特点,通过对项目生物安全柜的使用率、实验室最小送风量、生物安全柜排风量的分析,得出2种变风量模式能耗对比公式,从而优选出适合项目的变风量模式。

Abstract：
This paper presents two commonly used variable air volume modes for second-level biosafety laboratories with B2-type biosafety cabinets. Based on the characteristics of a laboratory project in the north city, by analysing the utilization rate of the biosafety cabinet, the minimum supply air volume in the laboratory, and the exhaust air volume of the biosafety cabinet, a comparison formula for the energy consumption of the two variable air volume modes is obtained, and the suitable variable air volume mode for the project is selected.
