Better Follow These 5 Ways To Eliminate Odors From Your HVAC System

Different causes of offensive odors necessitate different approaches to removing them. Our sense of smell is a potent perceptual tool that predates other senses in evolution. So take a deep breath and learn about odors and how to deal with offensive odors.

Smell. When you are born, it is the first sense you utilize, and by the time you are an adult, you can recognize 10,000 different scents. Various areas of your brain are directly activated by scent neurons, unlike other senses like hearing and sight.

A portion of the nasal canal contains receptor cells that pick up odor molecules and provide a signal to the brain.

Entering a bakery, walking on recently mowed grass, or getting wet after a dry spell. Our nose receives all of the associated odors via minute molecules. Actually, all odours are only vapours coming from the source. The only thing your nose can perceive is the evaporated liquid; neither a solid object nor a liquid can be smelled.

And it holds true for perspiration, grease, diesel, and cooking odors. Here are five strategies to prevent these offensive odors from settling in areas they shouldn’t.

1) Filter Maintenance

Start with a simple question. One or more cleaning filter sections that sieve out dust and other particles are located inside the air handling unit. When all those particles gather, they may serve as a breeding environment for bacteria, producing an unpleasant odor and maybe posing health risks.

The majority of air handling units have a differential pressure sensor that sounds an alarm when there has been a buildup. However, at that point it is actually too late, and routine cleaning is the best preventative measure.

2) Balance The Pressure For Heat Recovery

This advice is especially useful for systems that use an air handling unit-mounted heat recovery wheel. These wheels are a significant asset for energy savings because of their 70% efficiency. They are situated where two air streams converge, transferring energy from the departing stream to the entering stream.

However, air can leak from the outgoing into the incoming stream if the balance within the air handling unit is not appropriately set. This may result in unpleasant odors as well as a reduction in energy efficiency.

3) The Balance Of Over- And Under-Pressure

The direction in which air travels and the pressure distribution within a certain space are crucial factors to consider while commissioning an HVAC system. In places like restrooms, galleys, and mess halls, a negative pressure is produced by making certain adjustments to the pressure balance. This may mean that unpleasant odors are unable to exit the area since the negative pressure forces them to remain and be extracted in that space.

This balance might be upset over time. An imbalance in the pressure can result from repairs or modifications made to the duct system or from the installation of a new fan.

4) Carbon Active Filters

Using an active carbon filter is a good technique to get rid of odors. These receive a particular process that renders them extremely porous, enabling them to take in significant quantities of undesirable atoms and molecules.

If the active carbon filter is exposed to a stream of air for a long enough period of time, it will cleanse the air. Due to the limited lifetime of active carbon, make sure the filter is frequently updated. The filters need to be changed every few months, depending on how they are utilized.

5) Scenting

Instead of eliminating a scent from the air, this one involves introducing one. HVAC scenting entails distributing an aroma that permeates the ductwork, the cabins, and the rooms. The diffuser system can be attached to an existing air handling device, and hotels and retail establishments currently employ this technology (where it is said to stimulate people to buy specific products)

Wrapping Up

A significant element that affects our sense of comfort is scent. However, this does not imply that all odors are undesirable. In a galley or mess hall, cooking smells are not unpleasant. And there is nothing wrong with some odors in the bathroom or the scent of diesel in a sensitive garage. The main problem is when odors are present in places where they are obviously not welcome.
