摘要:

高等級生物安全實驗室氣密性高,壓差波動難以控制。分析了高等級生物安全實驗室內壓差的擾動因素,認為控制實驗室壓差的關鍵是增加系統的自適應性及采用壓力相關型閥門。針對各種擾動因素的控制提出了建議和要求,并在實際項目應用中得到驗證。

關鍵詞:高等級生物安全實驗室;氣密性;壓差波動;自適應性;壓力相關型閥門

Abstract:

The pressure difference fluctuation in high-level biosafety laboratories is difficult to control due to the high air tightness. This paper analyses the disturbance factors of the pressure difference in the high-level biosafety laboratory, and considers that the key to controlling the pressure difference in the laboratory is to increase the adaptability of the system and adopt the pressure-related valve. This paper puts forward some suggestions and requirements for the control of various disturbance factors, which have been verified in the actual project application.
