空气净化系统
空气过滤器的设置:
空调箱上安有初、中效过滤器,送至房间的排风管末端安装高效过滤器,初效主要过滤>10μm的尘粒,中效主要过滤1-10μm的尘粒,高效主要过滤<1μm的尘粒。
空气过滤器的维护:
初、中效过滤器:正常情况下每月清洗更换一次,如果在初效阻力达到50Pa、中效阻力达到80 Pa时也进行清洗更换;换入空气过滤器前先检漏,检查是否有破损情况,确认完整后换入。
高效过滤器:如果高效过滤器终阻力达到初阻力2倍、高效过滤器风量小于原风量70%或高效过滤器有渗漏时更换高效过滤器。
空调系统温、湿度控制:
温度:通过蒸汽加热或冷冻水的调节空调箱内流通空气的温度。
湿度:通过蒸汽加湿器加湿或表冷器冷却降湿。
净化空气的监测:
沉降菌监测:生产时每日采样监测
浮游菌、尘埃粒子监测:每月一次
Supplement for Air Cleaning System
Setting of Air Filter: Primary and secondary filters are mounted on the air conditioner and a HEPA filter is available at the end of air pipe leading to the room. The primary filter is for filtering of particles >10μm; The secondary filter is for filtering of particles 1-10μm; The HEPA filter is for filtering of particles <1μm.
Maintenance of Air Filter:
Primary/secondary filters: Under normal conditions, cleaned and replaced every month. A cleaning and replacement is also required when the resistance at primary filter reaches 50 Pa or reaches 80Pa at secondary filter. A pre-inspection for leakage or possible damage is required before replacing with a new filter.
HEPA filter: The HEPA filter shall be replaced with a new when the final resistance increases to twice the initial resistance, or the air volume decreases to less than 70% of original volume, or leakage occurs to the filter.
Temperature /Humidity control of Air Conditioner System:
Temperature: The temperature of air inside the air conditioner is regulated by heating vapor or freezing water.
Humidity: Regulated by a moistener and a Wet Surface Air Cooler.
Monitoring of Cleaned Air:
Monitoring of settling microbes: Conducted each day during production.
Monitoring of air-borne microbes and particles: Every month
