　　通風(fēng)裝置在疫情防控中的重要性

The importance of ventilation devices in epidemic prevention and control

　　空調(diào)通風(fēng)系統(tǒng)能夠決定空氣質(zhì)量的好壞，可以說是一把無形的雙刃劍，通風(fēng)系統(tǒng)的衛(wèi)生和干凈不能直接忽視掉。由于忽視了通風(fēng)裝置的衛(wèi)生和干凈，已經(jīng)產(chǎn)生很多由于不注重通風(fēng)裝置設(shè)施的建設(shè)或者不規(guī)范的建設(shè)導(dǎo)致疫情傳播的事件。

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.

　　由于病毒可以通過空氣中的飛沫和氣溶膠進行快速大量的傳播，人群集中的辦公室場所通風(fēng)不暢，人員密度大，在室內(nèi)感染病毒的概率比室外的要高出許多，沒有配備消毒模塊的中央空調(diào)通風(fēng)系統(tǒng)很容易出現(xiàn)交叉感染的可能。在后疫情防控的時代，不僅需要干凈整潔的空氣，還需要提高產(chǎn)品整體對防疫的能力?？照{(diào)通風(fēng)系統(tǒng)的凈化功能已經(jīng)成為了社會各界關(guān)注的重點。

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，市面上出現(xiàn)多種品類的凈化消毒裝置，常見的凈化消毒裝置有光催化，負離子，臭氧等技術(shù)。越來越多的通風(fēng)系統(tǒng)安裝在室內(nèi)建筑會通過安裝凈化消毒裝置來阻斷病毒的傳播，從根源上減少病毒通過空調(diào)系統(tǒng)的傳播。因此，市面上出現(xiàn)越來越多的凈化消毒裝置產(chǎn)品。所以為了統(tǒng)一標(biāo)準(zhǔn)，相關(guān)產(chǎn)品的標(biāo)準(zhǔn)化就很重要。2021年，由中國建筑科學(xué)研究院主編的2003-2021《建筑通風(fēng)系統(tǒng)用空氣凈化消毒裝置》開始實施。改標(biāo)準(zhǔn)明確了空氣凈化裝置的風(fēng)阻，凈化效率，微生物滅殺率，等主要功能。進一步規(guī)范了當(dāng)前空調(diào)系統(tǒng)用凈化消毒裝置的市場方向，在抗疫面前做出貢獻。

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.

　　空調(diào)通風(fēng)系統(tǒng)凈化消毒的必要性

The necessity of purifying and disinfecting air conditioning and ventilation systems

　　1：降低能耗：空調(diào)盤管機組、制冷制熱銅管會由于灰塵的累積產(chǎn)生污垢，污垢會導(dǎo)致熱量的傳導(dǎo)效率降低，凈化灰塵后，制熱和導(dǎo)熱效率會到正常的功率，節(jié)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：保護設(shè)備內(nèi)部：提高使用壽命：如果不注重對空調(diào)通風(fēng)系統(tǒng)的清潔，系統(tǒng)內(nèi)部會有風(fēng)管內(nèi)壁被腐蝕的現(xiàn)象。清洗后能夠大大改善這種情況，從而起到保護設(shè)備，延長使用壽命。

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：預(yù)防細菌通過空氣的傳播：空調(diào)內(nèi)部很容易滋生細菌病毒，嚴(yán)重可能對人體產(chǎn)生傷害很大的細菌。經(jīng)過消毒過后，能夠殺滅空調(diào)系統(tǒng)管道內(nèi)部的病菌，另外還能夠致使細菌沒有適合的生長環(huán)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.
