      通风空调工程
      Ventilation and air conditioning engineering
      1.净化实验室应避免多个实验室共用一个空调机组的状况,独自的空调机组可有效地避免穿插污染,节省运转成本。2.实验室空调规划参数应参照《生物安全实验室建筑技术标准》相关要求,在规划时还应考虑到生物安全柜、离心机、培养箱等设备的热、湿负荷。
      1. Purification laboratories should avoid the situation that multiple laboratories share a single air conditioning unit. Individual air conditioning units can effectively avoid intersection pollution and save operating costs. 2. The planning parameters of laboratory air conditioning should refer to the relevant requirements of "Technical Standards for Building Biosafety Laboratories", and the thermal and wet loads of biological safety cabinets, centrifuges, incubators and other equipment should also be taken into account in the planning.
      3.空气净化体系应设置粗、中、高三级空气过滤,粗效过滤器应设在新风口处,中效过滤器应在空调机组的正压段,高效过滤器应设体系的送风结尾。4.新风口距地上高度不低于2.5m,新风口应有防雨及防鼠虫措施,应设有易撤除清洗的过滤网。
      3. The air purification system should be equipped with coarse, medium and high three-stage air filtration, the coarse filter should be located at the fresh air outlet, the medium-effect filter should be in the positive pressure section of the air conditioning unit, and the high-efficiency filter should be equipped with the air supply end of the system. 4. The height of the fresh air outlet is not less than 2.5 m above ground. The fresh air outlet should be protected against rain and rodents and insects, and should be equipped with a filter which can be easily removed and cleaned.
      5.实验室的排风机应与送风机连锁,排风机应先于送风机敞开,后于送风机关闭,室内排风管道与生物安全柜等设备的排风管道应分开设置。6.净化室内送排风应选用上送下排方式。室内送风口和排风口布置应使室内气流阻滞的空间降低到较小程度。
      5. Exhaust fans in laboratories should be interlinked with supply fans. Exhaust fans should be opened before supply fans and closed after supply fans. Indoor exhaust ducts and exhaust ducts of biological safety cabinets should be set separately. 6. The air supply and exhaust in purifying room should choose the upper and lower exhaust modes. The layout of indoor air supply and exhaust outlets should reduce the space of indoor air flow obstruction to a lesser extent.
      7.实验室的各区之间应保持不小于5Pa 的压差,确保气流是从清洁区流向污染区,应在易于调查的位置设置压差表。8.过滤器和空调机组不能使用木质资料,应耐消毒剂腐蚀、不吸水的资料,空调机组的漏风率应小于2%。9.舒适性空调首要是选用风机盘管加新风体系,冬夏季使用医院集中的冷热源,如果春秋时节医院没有冷热源,可自备风冷式模块机组提供冷热源。
      7. Pressure difference of not less than 5 Pa should be maintained between different areas of the laboratory to ensure that air flow flows from the clean area to the polluted area. Pressure difference meters should be set up at locations that are easy to investigate. 8. Filters and air conditioning units should not use wood materials. They should be resistant to disinfectant corrosion and non-absorbent materials. The air leakage rate of air conditioning units should be less than 2%. 9. The primary choice of comfortable air conditioning is fan-coil unit plus fresh air system. In winter and summer, the hospital uses centralized cold and heat sources. If there is no cold and heat source in spring and autumn, the hospital can provide cold and heat sources with its own air-cooled modular units.

      1. Lighting system (1) Laboratory illumination (> 300 LX buffer room), preparation (> 200 LX office area illumination (> 200 LX blood collection desk surface illumination (> 500 lx). (2) Closed lamps should be selected in the purification area, and general lamps can be selected in the general experimental area according to the ceiling data. (3) The laboratory should be equipped with ultraviolet sterilization lamp, which can be equipped with a ultraviolet lamp (30W) at 10-15_. 4) The number and location of scattered light, emergency light and exit light shall be planned according to relevant fire control standards. 2. Power distribution system (1) When conducting electrical planning, enough sockets should be set up, and the power consumption of the primary equipment in the laboratory should be known in advance, and special distribution boxes should be set up in the biosafety laboratory.
      (2)在规划不间断电源前应与实验室负责人交流,确定需求不间断电源供电的设备及较短供电时刻,不间断电源放置的位置应通风条件良好。3. 弱电体系(1)电话网络终端:在实验室内应设置足够多的电话网络终端,满意实验室信息化办理的要求。(2)门禁体系:可限制非授权人员的进入,确保实验室的安全。(3)监控体系:可监控实验室人员的出入状况、日常工作状况、视频教学等。(4)呼叫体系:实验室内应设置紧迫呼叫分机,呼叫主机应设在值勤室内。
      (2) Before planning the uninterruptible power supply, we should communicate with the person in charge of the laboratory to determine the equipment and short power supply time needed for the uninterruptible power supply. The location of the uninterruptible power supply should be well ventilated. 3.
