空氣淨化技術一般采用哪些技術？

In a certain space, the purification project will remove the particles, harmful air, bacteria and other pollutants in the air, and control the indoor temperature, cleanliness, pressure, air velocity and air distribution, noise, vibration, lighting and static electricity within a certain demand range. No matter how the external air condition changes, the rooms specially designed for the purification project have the performance of maintaining the cleanliness, temperature, humidity and pressure as originally set.

空氣淨化工程按原理（lǐ）分（fèn）為亂流潔淨室和層流潔淨室。按應用（yòng）分為工業淨化（huà）工程，生物淨化（huà）工程。空氣淨化程（chéng）是一整套係統，潔淨廠房設計和驗收規範裏就（jiù）有說明。大（dà）致包括潔淨室建築裝飾係統，淨化（huà）空調係（xì）統，水係統、電係統、氣係（xì）統等，對潔淨室內的溫度（dù）、濕度、照度、潔淨度（dù）、靜電現象進行管控，從而達到特定的（de）工藝要求。

According to the principle, the air purification project is divided into turbulent clean room and laminar clean room. According to the application, it can be divided into industrial purification engineering and biological purification engineering. The air purification process is a complete system, which is described in the design and acceptance specification of clean workshop. It mainly includes the decoration system of clean room, purification air conditioning system, water system, electricity system, gas system, etc. it controls the temperature, humidity, illumination, cleanliness and electrostatic phenomena of clean room, so as to meet the specific process requirements.

空氣淨化器（qì）工作原理分類主動淨化類無（wú）濾網（wǎng）型根據這（zhè）些產品的主動殺菌原理可分為（wéi）銀離子技術、負離子技術、低溫等（děng）離子技術、光（guāng）觸媒技術和淨離子（zǐ）群離子技術。

空氣淨化工程的工作原理是：用風機將空氣抽入機器，通過內置的濾網過濾空氣，主要能夠起到過（guò）濾粉塵、異味、有毒氣體和殺滅部分細菌的作用。濾（lǜ）網（wǎng）又分：集塵濾網、去（qù）甲醛濾網、除臭濾網（wǎng）、HEPA濾網等。其中成本比較高的就是（shì）HEPA濾（lǜ）網，它能起到分解有毒氣（qì）體和殺菌作用，特別是抑製二次汙染。這類產品的特點是風機功能以及濾（lǜ）網的質量決（jué）定淨化效果，機器的放置以及室內布局（jú）影響淨化是否完全，室內淨（jìng）化效果不均衡，也（yě）難以完全（quán），濾網更換費用（yòng）較高。

The working principle of the air purification project is: use the fan to pump the air into the machine and filter the air through the built-in filter screen, which can mainly filter the dust, peculiar smell, toxic gas and kill some bacteria. Filter screen is divided into: dust collection filter screen, formaldehyde removal filter screen, deodorization filter screen, HEPA filter screen, etc. One of the high cost is HEPA filter, which can decompose toxic gas and sterilize, especially inhibit secondary pollution. The features of this kind of products are that the function of fan and the quality of filter screen determine the purification effect, the placement of machine and indoor layout affect whether the purification is complete, the indoor purification effect is not balanced, and it is difficult to complete, and the replacement cost of filter screen is high.

代：銀離子淨化技術

The first generation: silver ion purification technology

簡單地說就（jiù）是把銀塊（kuài）離子化吹到（dào）空（kōng）氣中以起到殺菌的效果缺點產品成本高，細菌（jun1）殺滅率低，對病毒幾乎沒有殺滅特性。

In short, it is to blow the silver block ionization into the air to have a bactericidal effect. However, the product cost is high, the bactericidal rate is low, and there is almost no killing characteristic for the virus.

第二代：離子（zǐ）技術

Second generation: ion technology

主要原理是運用靜電釋放負（fù）離子，吸附集中空氣中的粉塵起到（dào）降塵作用（yòng），同時負（fù）離子對空（kōng）氣中的氧氣也有電離成臭（chòu）氧的作用，對細菌有一定的殺滅作用，這類產品優點（diǎn）是產品生產成本較低。

The main principle is to use static electricity to release negative ions, absorb and concentrate the dust in the air and play a role in dust reduction. At the same time, negative ions can also ionize the oxygen in the air into ozone and kill bacteria to a certain extent. The advantage of such products is that the production cost is low.

第（dì）三代：溫等離（lí）子技術

The third generation: warm plasma technology

主要原理是，通過給氣體外加電壓至氣體的放電（diàn）電壓，使氣體被擊穿（chuān），產生各種強氧（yǎng）化性的低溫等離子，並在極短時間內把接觸。

The main principle is that the gas is broken down by applying voltage to the discharge voltage of the gas, producing various kinds of low-temperature plasma with strong oxidation, and contacting in a very short time.
