通风装置在疫情防控中的重要性

The importance of ventilation devices in epidemic prevention and control

　　空调通风系统能够决定空气质量的好坏，可以说是一把无形的双刃剑，通风系统的卫生和干净不能直接忽视掉。由于忽视了通风装置的卫生和干净，已经产生很多由于不注重通风装置设施的建设或者不规范的建设导致疫情传播的事件。

The air conditioning and ventilation system can determine the quality of the air, and can be said to be an invisible double-edged sword. The hygiene and cleanliness of the ventilation system cannot be directly ignored. Due to the neglect of the hygiene and cleanliness of ventilation devices, many incidents of epidemic transmission have occurred due to the lack of attention to the construction of ventilation facilities or non-standard construction.

　　由于病毒可以通过空气中的飞沫和气溶胶进行快速大量的传播，人群集中的办公室场所通风不畅，人员密度大，在室内感染病毒的概率比室外的要高出许多，没有配备模块的空调通风系统很容易出现交叉感染的可能。在后疫情防控的时代，不仅需要干净整洁的空气，还需要提高产品整体对防疫的能力。空调通风系统的净化功能已经成为了社会各界关注的。

Due to the rapid and large-scale transmission of viruses through droplets and aerosols in the air, office spaces with concentrated populations have poor ventilation and high personnel density. The probability of virus infection indoors is much higher than outdoors, and central air conditioning ventilation systems without disinfection modules are prone to cross infection. In the post epidemic prevention and control era, it is not only necessary to have clean and tidy air, but also to improve the overall product's ability to prevent the epidemic. The purification function of air conditioning and ventilation systems has become a focus of attention from all sectors of society.

　　目前，市面上出现多种品类的净化装置，常见的净化装置有光催化，负离子，臭氧等技术。越来越多的通风系统安装在室内建筑会通过安装净化装置来阻断病毒的传播，从根源上减少病毒通过空调系统的传播。因此，市面上出现越来越多的净化装置产品。所以为了统一标准，相关产品的标准化就很重要。2021年，由建筑科学研究院主编的2003-2021《建筑通风系统用空气净化装置》开始实施。改标准明确了空气净化装置的风阻，净化效率，微生物灭杀率，等主要功能。进一步规范了当前空调系统用净化装置的市场方向，在抗疫面前做出贡献。

At present, there are various categories of purification and disinfection devices on the market, and common purification and disinfection devices include technologies such as photocatalysis, negative ions, ozone, etc. More and more ventilation systems are installed in indoor buildings to block the spread of viruses by installing purification and disinfection devices, thereby reducing the spread of viruses through air conditioning systems at the root. Therefore, an increasing number of purification and disinfection device products are appearing on the market. So in order to standardize, it is important to standardize related products. In 2021, the 2003-2021 "Air Purification and Disinfection Devices for Building Ventilation Systems" edited by the Chinese Academy of Building Sciences began to be implemented. The standard has clarified the main functions of air purification devices, such as wind resistance, purification efficiency, and microbial killing rate. Further standardizing the current market direction of purification and disinfection devices for air conditioning systems, and making contributions in the face of epidemic prevention.

　　空调通风系统净化的必要性

The necessity of purifying and disinfecting air conditioning and ventilation systems

　　1：降低能耗：空调盘管机组、制冷制热铜管会由于灰尘的累积产生污垢，污垢会导致热量的传导效率降低，净化灰尘后，制热和导热效率会到正常的功率，节省能源

1: Reduce energy consumption: Air conditioning coil units and refrigeration and heating copper pipes will accumulate dirt due to the accumulation of dust, which will reduce the efficiency of heat conduction. After purifying the dust, the heating and thermal conductivity efficiency will reach normal power, saving energy

　　2：保护设备内部：提高使用寿命：如果不注重对空调通风系统的清洁，系统内部会有风管内壁被腐蚀的现象。清洗后能够大大改善这种情况，从而起到保护设备，延长使用寿命。

2: Protecting the interior of the equipment: Improving its service life: If the cleaning of the air conditioning and ventilation system is not emphasized, there may be corrosion on the inner walls of the air ducts inside the system. Cleaning can greatly improve this situation, thereby protecting the equipment and extending its service life.

　　3：预防细菌通过空气的传播：空调内部很容易滋生细菌病毒，严重可能对人体产生伤害很大的细菌。经过过后，能够杀灭空调系统管道内部的病菌，另外还能够致使细菌没有适合的生长环境。

3: Preventing the spread of bacteria through the air: It is easy for bacteria and viruses to breed inside air conditioners, which may cause significant harm to the human body. After disinfection, it can kill the bacteria inside the pipes of the air conditioning system, and also cause the bacteria to not have a suitable growth environment.
