According to analysis of the production and descriptive personnel of the associated purification equipment such as an air filter, radiation energy is indicated by radiation output, radiation intensity, and radiation amount. The radiation output is the energy radiated by the radiator at the unit time, which is equivalent to the luminous flux of the fluorescent lamp; the radiation intensity is the radiation output per unit area; and the radiation amount is the product of the radiation intensity and the radiation moment. The radiation output can change with the temperature, humidity, wind speed and Other factors of the operating environment. When the ambient temperature is low, the output can be low. Addition of humidity to the sterilizer will also be degraded. The UV lamp is usually depicted at a relative humidity of 60%. When indoor humidity added
According to analysis of the production and descriptive personnel of the associated purification equipment such as an air filter, radiation energy is indicated by radiation output, radiation intensity, and radiation amount. The radiation output is the energy radiated by the radiator at the unit time, which is equivalent to the luminous flux of the fluorescent lamp; the radiation intensity is the radiation output per unit area; and the radiation amount is the product of the radiation intensity and the radiation moment.
The radiation output can change with the temperature, humidity, wind speed and other factors of the operating environment. When the ambient temperature is low, the output can be low. Addition of humidity to the sterilizer will also be degraded. The UV lamp is usually depicted at a relative humidity of 60%. When the indoor humidity is added, because the sterilization effect is reduced, the amount of illumination should also be added accordingly. For example, when the humidity is 70%, 80%, and 90%, in order to achieve the same sterilization effect, the amount of radiation must be increased by 50%. 80%, 90%. The speed of wind also affects the output ability. In addition, because the sterilizing effect of the UV lamp is not the same as the bacterial species, the amount of UV irradiation should be changed for different types of bacteria. For example, the killing amount of the fungicide is 40 to 50 times larger than that of the bacillus.
The radiant intensity of the UV lamp weakens with the addition of the flare interval. Taking the test data of a 30W ultraviolet lamp produced by a certain factory as an example, the radiation intensity is 72uw/cm2 when the radiation interval is 1m, 19.5uw/cm2 when the interval is 2m, and 8um/cm2 when the interval is 3m. Therefore, when thinking about the sterilization effect of ultraviolet sterilizing lamps, we can't neglect the influence of the height of the device.
The sterilizing power of the UV lamp decreases with the addition of the application time. The output power with 100h is the additional output power. The average life of the lighting time from the UV lamp to 70% extra power is the average lifetime when the UV lamp application time exceeds the average life. At that time, it would not achieve the desired effect. It is necessary to replace it at the moment, and the average lifetime of domestic UV lamps is usually 2000 hours.
The sterilization effect of ultraviolet rays is determined by the amount of radiation, and the amount of radiation is always equal to the radiation intensity multiplied by the moment of radiation. Therefore, to improve the radiation effect, it is necessary to add radiation intensity or extend the radiation time.
