How to Control Interior Humidity Levels

Here in the Southeast, there is no doubt about the fact that summer is in full swing. Already, the humidity level is making it feel like “the air you can wear” outside, when simply walking out the door can seem like putting on a damp, heavy sweater.

Even inside in a home with a good central heating and air conditioning (HVAC) system, the humidity level can spike, making it feel hotter than it would if the humidity was lower. It is also worth pointing out that when there is a high level of humidity inside, the HVAC system has to work extremely hard to both dehumidify and cool the air.

This equates to an efficiency loss as well as a financial loss, which could be avoided if the humidity was regulated. Understanding that approximately 80 percent of latent heat loads come from outside air, an enthalpic recuperator could be used to reduce the humidity. A dehumidifier could also be placed inside the home to pull moisture out of the air.

Aside from simply creating a more comfortable home environment, bringing the humidity level down can also result in a healthier indoor environment. This is due to the fact that a high level of humidity inside can create a more favorable environment for:

  • Mold growth
  • Dust mites
  • Insect proliferation
  • Increased asthma and allergy problems

It is also worth noting that metals corrode faster when there is a higher level of humidity, as a result of condensation. Wood is more likely to rot and floors, paintwork and wallpaper are also more likely to be damaged.

It is not as simple as saying that all the humidity should be removed, however. Having too little humidity inside a home can also be problematic. Although this is something that really only affects us here in the in the wintertime in the Southeast, when humidity levels dip alongside the outdoor air temperatures, it’s always good to be prepared.

Of course, the first thing that comes to mind when thinking of low humidity is dry, itchy skin, which by itself may not seem like much of an issue. The thing is, a number of studies showed recently how dry skin can impact several metabolic functions, such as oxygen intake and the shedding of water vapor, salts and heat. When the water vapor in our skin evaporates too quickly, the subsequent intake through capillary diffusion becomes an insufficient replacement and a variety of problems can arise.

Low levels of humidity can also harm sensitive IT equipment because of the additional static electricity. Purchasing a whole-home dehumidifier and humidifier could be the key to keeping a humidity range in between 30 and 70 percent, which is vital to creating the healthiest possible indoor air environment and ensuring your HVAC system operates at peak efficiency.
