Description

中央空调动态过滤、静态杀菌消毒空气净化系统及方法
本申请要求申请日为2020年3月26日、申请号为202010226091.6的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及环保技术领域，例如涉及一种中央空调动态过滤、静态杀菌消毒空气净化系统及方法。
背景技术
中央空调由一个或多个冷热源系统和多个空气调节系统组成的。中央空调具备相应的空气净化功能，现有的中央空调在进行空气净化时，系统的新风与回风混合先进入空气过滤器，将气体中的粉尘颗粒和微粒过滤，过滤后的干净空气然后进入空气调节处理器，与冷却介质进行换热降温，变成室内空间适宜的温度的空气，通过进风风机，经由送风管道分布输送到需要的空间，经由房间的送风口，送入房间，使房间保持一定的温度，然后再由回风口从房间排放汇集进入回风管道，通过回风风机，将一部分空气经过排风阀门调节，排放到大气环境，另一部分则通过回风调节阀，与补充的新鲜空气混合后，再次经过空气过滤器，将气体中鲜风部分带入的粉尘颗粒和微粒过滤，过滤后的干净空气然后进入空气调节处理器，实现过程的循环。
现有中央空调空气净化系统难以配置有效的空气杀菌消毒系统，主要原因在于：有效的空气杀菌消毒系统不论是采用化学方法或者物理方法，都难以实现中央空调大规模空气处理能力的动态杀菌消毒，一是消毒物质的浓度，或消毒辐射的强度，二是气体在杀菌消毒装置空间的接触(停留)时间。比如，目前有效的化学消毒杀菌方法之一是臭氧工艺，要想在单位时间内提供足够的臭氧，其臭氧发生器的功率要足够大，要想达到有效的杀菌消毒效果，实现足够的接触(停留)时间，设备的空间体积要足够大，这在动态过程中是难以实现的，同时在动态杀菌消毒和空气过滤净化过程中臭氧还容易进入空气循环系统，进而进入人群活动的空间，造成对人体的不良影响。
同样采用物理方法紫外线或者微波杀菌消毒工艺，要想在单位时间内提供 足够的紫外线强度(微波强度)，其紫外光管的数量和装机功率(微波发生器的功率)均需要足够大，要想达到有效的杀菌消毒效果，实现足够的接触(停留)时间，设备的空间体积要足够大，这在动态过程中也是难以实现的。为此我们彻底颠覆现有杀菌消毒理念的传统思维，提出动态中央空调的动态过滤净化、静态杀菌消毒空气净化系统。
