The cross-flow fan of the wall-mounted circulating air ultraviolet disinfection machine sucks part of the dirty air in the room into the disinfection machine, performs air purification and super-strong ultraviolet lamps to instantly kill bacteria in the flowing air, and filters out dust and 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 circulating air UV disinfection machine is ultraviolet light, so what is the relationship between the ultraviolet radiation in the wall-mounted circulating air UV disinfection machine and the disinfection effect? Does it mean that the stronger the ultraviolet radiation in the wall-mounted circulating wind UV disinfection machine, the better the disinfection effect of the wall-mounted circulating wind UV disinfection machine? In order to draw an objective and fair conclusion, we must first pay attention to several comparable conditions: 1. The wall-type circulating air UV disinfection machine should be suitable for the same volume (refer to the same specifications and models for comparison). 2. The wall-mounted circulating air ultraviolet disinfection machine is placed in the same volume of the room at the same time (referring to the same comparative environment). 3. The opening time of the wall-mounted circulating air UV 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 circulating air UV disinfection machine (alias wall-mounted circulating air UV disinfection machine): 1. The air volume and disinfection of the fan of the wall-mounted circulating air UV disinfection machine in Inner Mongolia Air speed and air supply distance of the air outlet: 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 speed and air supply distance of the air outlet of the disinfection machine refer to The farthest distance that the disinfection machine can send the clean air after treatment. Just imagine, if even the clean air after the disinfection machine treatment 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, 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 circulating air ultraviolet 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 air circulating air UV 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 sterilizer enters the air vertically downwards and exhausts the air vertically upwards, and the clean air treated by the wall-mounted circulating air circulating air UV disinfection machine is sent to the ceiling of the room and then turned back down, and then it is caused by the hanging circulating air circulating air UV disinfection machine. The fan flows back into the sterilizer. Does the wall-mounted circulating air circulating air UV sterilizer 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 circulating air ultraviolet disinfection machine are designed by referring 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 circulating air ultraviolet disinfection machine filter or filter for air purification: The 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 , Air purification special (initial effect + medium effect + activated carbon + photocatalyst) composite filter with large ventilation, large dust holding capacity and high filtration efficiency. 4. Wall-mounted circulating wind UV 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 on the UV radiation intensity test method: 5 minutes after turning on the UV lamp, the voltage Stable 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 ultraviolet lamp in the wall-mounted circulating air ultraviolet disinfection machine depends on it As for the test methods, if the test methods are 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 greater the irradiance value, the better the wall-mounted circulating air 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 circulating air UV sterilizers The overall performance is better! In summary, the ultraviolet radiation in the wall-mounted circulating wind ultraviolet 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!
