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
