UV light is an underused and misunderstood instrument for the disinfection of indoor air. We have several reasons for you to take advantage of what ultraviolet lighting provides. It’s used in research laboratories and hospitals for the sterilization of rooms and equipment, and researchers haven’t found any superbug that’s resistant to UV-C rays yet.
UV light history for disinfection
Since the ’30s, UV light has been used for the sterilization of equipment in research laboratories and hospitals. In the ’90s, there was a move to make use of UV-C for improving the quality of indoor air by minimizing the microbial build-up in HVAC coils. In the year 2013, the CDC (Centres for Disease Control and Prevention) participated in a particular study that has to do with the elimination of a couple of superbugs that can be found in hospital rooms making use of a disinfection system incorporating germicidal UV-C light.
Types of Ultraviolet Rays
There are three types of UV rays, and they include:
- UV-A light
This has the least harmful effect, and its wavelength is the longest. It’s commonly called the “black light.”
- UV-B light
This is the light that results in sunburn anytime one is exposed to it for a long period of time, and it improves the rate of having skin cancer. The Ozone layer absorbs about 95 percent of the UV-B light, which makes it never reach the Earth.
- UV-C light
This is the one with the shortest wavelength. This UV ray is the most harmful type, and the atmosphere of the Earth absorbs almost all of it. UV-C is used to sanitize water, air, and food because it disintegrates the nucleic acids found in the microorganisms’ cells. Without proper usage, UV-C light can be harmful to humans.
Mode of operation of UV-C lamps
When used appropriately, UV-C light can get rid of several types of viruses, bacteria, molds, fungi, and also other microorganisms. When the light is placed properly, it can get rid of every pathogen from the air that passes through an HVAC unit.
How heat transfer efficiency and airflow is improved by UV light
As time goes on, fungi and mold grow on HVAC coils and around them, which undermines the efficiency of the unit and reduces airflow. When you install ultraviolet lights within the coil system or in the coil system of an HVAC unit, it will offer an adequate layer of protection from several harmful microorganisms from the air. When you place UV lighting in the coil system. It will also restrict airflow and help you destroy the fungus and mold that build up on coils. This upgrade has the tendency of restoring coils to their initial efficiency level and drastically increases airflow. If you augment an HVAC unit with UV-C, it will last longer and need reduced maintenance because it doesn’t need to function too hard for air to flow through the coils. In addition to the several benefits of UV-C, it can also reduce the cost you spend on your HVAC system.
We can help you install LED UV-C lamps whose wavelength is 254nm, as it’s the best for disinfection. And yes, our lamps are installed in your HVAC unit so it’s rays won’t fall on your skin, thereby not causing any harm. Reach out to us now for the best service.
