Uv Lamp Sanitizer For Hvac

the eyes can not stare at the ultraviolet lamp for a long time. Ultraviolet light has certain damage to human skin, the use of ultraviolet light should pay attention to good protection, the eyes must not look directly at the ultraviolet light source, otherwise the eyes will be damaged..

Household ultraviolet disinfection should pay attention to what matters

1, Do not make ultraviolet light source irradiation to people, so as not to cause damage.The effects of ultraviolet light are most obvious on the skin and eyes.The human body by short time irradiation will produce skin flushed, itching, allergic papules; Long time irradiation can cause serious damage to skin tissue, and sufficient dose of irradiation can even cause skin cancer.Ultraviolet radiation to the human eye is also very harmful, short-term exposure to a large dose will make the eyes swollen, tears, unable to open, long-term exposure to ultraviolet radiation will lead to cataracts and even blindness.

2. When disinfecting the surface with ultraviolet light, the irradiated surface should be directly irradiated by ultraviolet light, and sufficient irradiation dose should be reached.Because light travels in straight lines, it is reflected, penetrated or absorbed when it is blocked by objects.Ultraviolet disinfection requires that the wattages of ultraviolet lamps per cubic meter of space are greater than or equal to 1.5W, and the irradiation time is generally 30-60 minutes.And stipulated that the irradiation intensity of ultraviolet rays should not be less than 70ūW/cm2, otherwise the sterilization effect is not good or invalid, and the purpose of disinfection cannot be achieved.

3, The suitable temperature range of ultraviolet disinfection is 20℃~40℃, too high or too low will affect the disinfection effect.When disinfecting indoor air with ultraviolet light, the room should be kept clean and dry to reduce dust and water mist. When the temperature is lower than 20 ° C or higher than 40 ° C and the relative humidity is greater than 60%, the irradiation time should be appropriately extended.

4, The application should also pay attention to the lamp tube wipe and cleaning.When the new lamp is used, 75% alcohol gauze can be used to wipe the lamp tube to remove dust and oil stains on the lamp tube pollution.In the process of use, wipe regularly, do a good job of lamp cleaning, so as not to affect the purple penetration rate and radiation intensity.

Its main principle is through the ultraviolet irradiation, penetrates the microbial cell membrane, destroying all kinds of germs, bacteria, parasites and other circulating DNA structure, destroyed its nucleic acid molecular bonds, the bacteria died instantly or can't reproduce, and the changing structure of microbial DNA (deoxyribonucleic acid), so as to achieve the purpose of sterilization.

When a microorganism passes through UV-C, the light penetrates the organism's nucleus, breaking the molecular bonds of its DNA.This disruption or breakage prevents microbes from multiplying.Without the ability to reproduce, the organism dies within seconds and is unable to reproduce.Some airborne pathogens are more resilient to uv energy than others.Viruses, for example, are easier to destroy than bacteria, and the effective reduction of mold spores requires maximum uv light.

Airborne pathogens are invisible to the naked eye and most are so small that they can easily pass through standard air filters. Adding ultraviolet air disinfection to the filtration equation prevents the growth of even the tiniest microbes.
