Correlation between ultraviolet radiation and disinfection effect in wall-mounted ultraviolet air disinfection machine

The correlation between the ultraviolet radiation and the disinfection effect in the wall-mounted ultraviolet air disinfection machine 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 ultraviolet light on the flowing air. Bacteria are instantly killed, and clean air that has been filtered out of dust and bacteria is returned to the room, and the clean air flows 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 disinfection machine 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 disinfection machine, the better the disinfection effect of the wall-mounted ultraviolet air disinfection machine? In order to draw an objective and fair conclusion, we must first pay attention to several comparable conditions: 1. 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 UV air sterilizer (alias wall-mounted circulating wind UV disinfection machine): 1. The air volume of the wall-mounted circulating wind UV disinfection machine fan, disinfection machine Air outlet 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 speed and air supply distance of the disinfection machine refer to disinfection The farthest distance that the machine can send clean air after treatment. Just imagine, if even the clean air after the disinfection machine can not 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. 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. Wall-mounted circulating air ultraviolet disinfection machine filter or filter for air purification efficiency: Wall-mounted circulating air ultraviolet disinfection machine adopts 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 (primary effect + medium efficiency + activated carbon + photocatalyst) composite filter with large ventilation, large dust holding capacity and high filtration efficiency. 3. Ultraviolet lamp irradiance of the hanging circulating air ultraviolet disinfection machine: Let’s take a look at the test method of ultraviolet radiation intensity in 2.1.5.4 of the 2002 version of the 'Disinfection Technical Specifications' of the Ministry of Health: Stable at 220V, use an illuminance meter to measure the irradiance value (uW/cm2) at the center of a vertical distance of 1m below the tube; it can be seen that the irradiance value of the ultraviolet lamp in the wall-mounted circulating air ultraviolet disinfection machine depends on its If the test method is not uniform, there will be no comparability. It's like testing the distance between 0.1m and 1m, and the measured irradiance is quite 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! 4. Whether the wall-mounted circulating wind ultraviolet air disinfection machine forms a fast 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 wind ultraviolet air disinfection machine fan, the air outlet wind speed of the disinfection machine, and the air supply distance are not repeated here. Imagine if the sterilizer enters the air vertically downwards and exhausts the air vertically upwards, the clean air treated by the wall-mounted circulating air ultraviolet air disinfection machine 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 ultraviolet air disinfection machine Inside the disinfection machine, does the wall-mounted circulating wind 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 sterilizer are designed with reference to the multi-faceted air inlet and full-angle wind layout of the wall-mounted air conditioner indoor unit. In summary, the ultraviolet radiation in the wall-mounted ultraviolet air sterilizer 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! For more information about UV air disinfection machine, please view
