In recent years, purification air conditioning technology has been widely used in scientific research, medical treatment, high-tech product production, laboratory and other fields. As the core of air purification control in laminar flow operating room, purification air conditioning system has high technical requirements, strict quality requirements in construction and installation process and large investment. Therefore, from the design, construction, maintenance to cleaning of the air conditioning system in the laminar flow operating room, special professionalism and strict system management are required.
1. Large air volume: the purification air conditioning system of laminar flow operating room mainly filters the dust and bacteria in the air through the circulation of air volume, so as to realize the control of non biological particles and biological particles in the air. In order to reach the purification standard, the amount of clean air enters into the laminar flow operating room to ensure the required cleanliness, so the air volume is far higher than the supply demand of room humid and hot air conditioning.
2. High accuracy of temperature and humidity control: different from ordinary comfortable air conditioning, it only meets the requirements of personnel comfort. The control accuracy of room temperature and humidity in laminar flow surgery meets the requirements of environmental treatment. Too cold is not good for the doctor's operation. Too hot will make the patient sweat and increase the chance of infection. Especially in organ transplantation and other special operations, low temperature and humidity will make bacteria easy to reproduce and affect the operation effect. In order to achieve constant temperature and humidity, the air handling unit at least needs to have refrigeration, heating, humidification, dehumidification and other functions, and needs to be accurately controlled.
3.高风压，系统:为了达到清洁空气的需求,层流手术室至少经常使用粗糙,中等和高三级过滤器,高级别洁净室有特殊要求,过滤器设置会更,和三重过滤阻力加起来650 ~ 800 pa,与此同时,为了保证维持洁净室是负压力调节要求,干净、回风方式,因此在管道洁净室是两个或两个以上常见的空调。为了克服这些阻力，空气处理装置的风扇需要有足够的压头。
3. High air pressure, system: in order to meet the needs of clean air, the laminar flow operating room often uses at least coarse, medium and high-level three-level filters. The high-level clean room has special requirements, the filter setting will be more, and the triple filter resistance will add up 650 ~ 800 Pa. at the same time, in order to ensure that the clean room is a negative pressure regulation requirement, clean and return air mode, so there are two or two in the pipeline clean room More than common air conditioners. In order to overcome these resistances, the fan of the air handling unit needs to have enough pressure head.
4. Strictly control the positive and negative pressure: in order to prevent the cross infection of virus and bacteria, it is very important to control the positive and negative pressure in the clean room, whether in the laminar flow operating room, isolation ward or laboratory animal. It is very important to control the positive and negative voltage accurately and effectively. In order to obtain the accurate control value of pressure difference, the air handling unit of laminar flow operating room is required to have a lower air leakage rate, so as to achieve a higher control accuracy.
5. High requirements for filtration system: in order to meet the operation requirements in sterile and dust-free environment, the laminar flow operating room must be equipped with a set of good air filtration system. The extent to which cleaning technology controls microorganisms, dust, etc., depends largely on the performance of the filter. The laminar flow operating room generally requires at least three levels of filtration, the air processing unit is equipped with primary and intermediate effect filters, and the air supply end is equipped with high efficiency filters. Air filters need to be of good quality. Once there is a leak, it cannot be cleaned.
The above is a detailed introduction to the measures for purifying air conditioning system in the decoration of laminar flow operating room. For more information, please click http://www.sdyhrs.com
