Viruses like the novel coronavirus, fungus, and bacteria can grow rapidly inside the Heating, ventilation, and air conditioning (HVAC) system due to the dark and damp environment and get dispersed all over the premise through the AC ducts. Without us realizing it makes the environment infectious, unsafe, and unhealthy and can increase health issues including flu, upper respiratory ailments, congestion, headache, and the novel coronavirus responsible for the COVID-19 pandemic.
Since the Middle of the 20th century, the use of short-wavelength ultraviolet (UV-C) light to kill microorganisms has been the most accepted air disinfection method. UV lamps for air purification can be a blessing for your HVAC system when it comes to control the spread of infection and diseases in your indoor environment
WHAT IS UV LAMP?
The ultraviolet lamp also called a black-light lamp is a device for generating electromagnetic radiations in the wavelengths between visible light and X-rays. A UV lamp is different from a regular lamp because it is made of quartz instead of glass. Inside the UV lamp, there is an inert gas combined with mercury. When the lamp is plugged in, electricity reacts with mercury, and the lamp produces UV light that is used to kill microorganism
INSTALLATION OF UV LAMPS INSIDE HVAC
Installing UV lamps in your HVAC system can improve your health providing you a comfortable and cleaner environment to breathe in, and extending the life of your system as well. MG cooling solution will guide and help you with easy installation of UV lamp with your new or existing HVAC system so that your premise will be healthy. There are 5 steps to install a UV lamp in your HVAC
- Choose where to install the UV lamp
it is very important to determine the appropriate location on your air handler to install a UV lamp as the wrong location can greatly affect its efficiency in preventing microbial growth. UV lamp can be installed in the evaporator coil that is usually the source of contamination. The evaporator coil is the part of air handler and is susceptible to biofilm growth which are communities of microorganism that makes it usually the best location to install the UV light
- Drill the hole(s) for the UV light
the next step is to drill hole(s) in the metal HVAC cover so that the UV lamp can be inserted but it is necessary to take proper measurement before drilling. The most UV lamp will need either a hole in the range of 1.5” to 3” in diameter
- Screw the germicidal UV light to the furnace
the next step is to screw the UV light into the air handler. Use a cordless drill to secure the UV lamp to the metal but make sure not to install the screw too tightly as it may crack the plastic of the UV lamp
- Power the A/C UV lamp system
Now UV lamp sanitizer is secured to the furnace it’s time to power the system. 5’-7’ long extension power cord is provided in most of the new UV lamps and now simply plug the unit into an existing outlet. One more option is to hardwire the UV lamp into the furnace so that the UV lamp will only turn on when the A/C turns on so it isn’t on 24 hours
- Change and clean the UV lamp
Generally, UV lamps will last about one year. Even if you see blue light shining this doesn’t mean that the bulb doesn’t need replacement. The actual UV-C frequency that kills microorganisms is not visible to the human eye. There may blue light originating from the unit but it is no longer shining enough UV-C light frequency.
UV lamps need to be cleaned after every season so that dust and debris won’t affect their performance. You can simply use a lint-free microfibre rag and can use a regular glass cleaning solution to clean UV lamp
Keeping the current situation in mind UV lamp installed in your HVAC is the perfect solution to reduce illnesses and allergies and it can also improve airflow and improve HVAC efficiency.
