Does wall-mounted ultraviolet air disinfection machine's ultraviolet radiation affect the disinfection effect?

The cross-flow fan of the wall-mounted ultraviolet air disinfection machine sucks part of the dirty air in the room into the disinfection machine, and performs air purification and super-strong ultraviolet lamps to instantly kill bacteria in the flowing air, and filter out the dust and killed The clean air that kills bacteria is sent back to the room, and the clean air circulates quickly to achieve the purpose of air purification and sterilization. It is not difficult to see here that the main disinfection factor of the wall-mounted ultraviolet air sterilizer is ultraviolet light, so what is the relationship between the ultraviolet radiation in the wall-mounted ultraviolet air disinfection machine and the disinfection effect? Does it mean that the stronger the ultraviolet radiation in the wall-mounted ultraviolet air disinfector, the better the disinfection effect of the wall-mounted ultraviolet air disinfector? In order to draw an objective and fair conclusion, we must first pay attention to several comparable conditions: 1. The wall-type ultraviolet air disinfection machine should be suitable for the same volume (refer to the same specifications and models for comparison). 2. The wall-mounted ultraviolet air disinfection machine is placed in a room of the same volume at the same time (referring to the same comparative environment). 3. The opening time of the wall-mounted ultraviolet air disinfection machine should be the same. Under the same conditions, let’s look at several key factors in the working principle of the wall-mounted ultraviolet air disinfection machine (alias wall-mounted circulating wind ultraviolet disinfection machine): 1. The air volume of the wall-mounted ultraviolet air disinfection machine fan and the air outlet of the disinfection machine Wind speed and air supply distance: The air volume of the fan is related to the number of air changes in the disinfection room. The air volume of the disinfection machine fan is generally 10 times or more than the volume of the disinfection room; the air outlet wind speed and air supply distance of the disinfection machine mean that the disinfection machine can The farthest distance that the treated clean air can be sent. Just imagine, if even the clean air treated by the disinfection machine can't reach the farther place, how much disinfection effect can there be? This answer is not difficult to make the correct answer. Here, the wind speed and air supply distance of the air outlet of the sterilizer are related to the air volume of the sterilizer fan and the cross-sectional area of u200bu200bthe sterilizer air outlet. For example, the larger the air volume of the sterilizer fan and the smaller the cross-sectional area of u200bu200bthe sterilizer outlet, the sterilizer will output The greater the wind speed of the tuyere, the farther the air supply distance of the sterilizer. The air volume of the wall-mounted circulating air ultraviolet disinfection machine fan is more than 10 times the volume of the disinfection room, and the cross-sectional area of u200bu200bthe air outlet of the disinfection machine refers to the layout design of the wall-mounted air conditioner indoor unit. 2. Whether the wall-mounted ultraviolet air disinfection machine forms a rapid circulating flow in the disinfection room, in other words, whether the disinfection machine forms a fast and uniform airflow organization in the room without dead ends. At this point, the factors such as the air volume of the wall-mounted circulating air ultraviolet air disinfection machine fan, the air speed of the air outlet of the disinfection machine, and the air supply distance are not repeated here. Imagine if the disinfection machine enters the air vertically downwards and exhausts the air vertically upwards, the clean air treated by the wall-mounted circulating air UV air sterilizer is sent to the ceiling of the room and then turned back down, and then returned by the fan of the wall-mounted circulating air UV air disinfection machine Inside the disinfection machine, does the wall-mounted circulating air ultraviolet air disinfection machine form a fast and uniform air flow in the room? As long as you think about it, it is not difficult to get the correct answer. The air inlet and outlet modes of the wall-mounted circulating air ultraviolet air disinfection machine are designed with reference to the multi-faceted air inlet and full-angle wind layout of the wall-mounted air conditioner indoor unit. 3. The efficiency of the wall-mounted ultraviolet air disinfection machine filter or filter for air purification: the wall-type circulating air ultraviolet disinfection machine uses a variety of air purification methods to reduce dust particles in the air. This machine adopts our company's independent research and development of low resistance, A special air purification (initial effect + medium effect + activated carbon + photocatalyst) composite filter with large ventilation, large dust holding capacity and high filtration efficiency. 4. Wall-mounted ultraviolet air disinfection machine UV lamp irradiance: Let’s take a look at the 2002 version of the Ministry of Health 'Disinfection Technical Specifications' 2.1.5.4 for the ultraviolet radiation intensity test method: the voltage is stable after turning on the ultraviolet lamp for 5 minutes At 220V, use an illuminance meter to measure the irradiance value (uW/cm2) at the center of the vertical distance of 1m below the tube; it can be seen that the irradiance value of the UV lamp in the wall-mounted circulating air UV disinfection machine depends on its test Method, if the test method is not uniform, there is no comparability. It's like testing the distance between 0.1m and 1m, and the measured irradiance is very different. Even if the test method is the same, does it mean that the higher the irradiance value, the better the wall-mounted circulating wind UV disinfection machine? I believe the truth that things must be reversed is understood. Remind you that the greater the ultraviolet irradiance of the sterilizer, the greater the damage to the housing of the sterilizer and the filter, connecting wires and other components inside the sterilizer. The pursuit of wall-mounted circulating air ultraviolet air sterilizers The overall performance is better! In summary, the ultraviolet radiation in the wall-mounted ultraviolet air disinfection machine is directly related to the disinfection effect, but many factors such as the air volume of the disinfection machine fan, the cross-sectional area of u200bu200bthe disinfection machine's air outlet, and the disinfection machine's air inlet and outlet methods cannot be ignored. A wall-mounted circulating wind UV disinfection machine with good comprehensive performance is a good disinfection machine!
