空气净化系统回风口过滤装置贴附尼龙网的效果评价

目的探讨利用医用橡皮膏使用后废弃的尼龙网,对空气净化系统回风口过滤装置进行贴附的效果评价。方法对回风口滤过装置贴附上尼龙网前后手术室的风速、细菌浓度和尘埃粒子量测定。结果贴附尼龙网前后所测数值不影响空调洁净系统的功能、净化的效果。结论对空气净化系统回风口过滤装置贴附尼龙网比每周擦拭效果更明显,省时、省力、省能源。

Assessment of Cleaning Effect by Replacing Filtering Apparatus Return-Wind Exit with Nylon Nets

OBJECTIVE To discuss the practicality of using the nylon nets,which are derived from disposed used medical(suture-band).The nylon nets were attached to the filtering apparatus on original return-wind exit on the lateral wall of surgical operating room.METHODS The velocity of wind,concentration of bacteria and the total(particle) amount of dust were determined by contrasting the number determined before and after passing the nylon nets on the(filtering) apparatus return-wind exit.RESULTS There was no evidence to influence the cleaning and temperature(regulating) effects of air conditioner by binding the nylon nets on them.CONCLUSIONS This method appears to save time as well as energy to work more efficiently than cleaning air conditioners weekly.
