Types of home Ventilation Systems

For many centuries, homes were not ventilated at all and life went on as usual. However, today the home ventilation system is a key feature in every home. This is because unlike centuries ago, the homes today have insulation that prevents the air from entering through the cracks, gaps and holes. This is on top of the fact that the building materials that were used 100 years ago were mostly natural.

There are different forms of ventilations. Some of the categories in which we can categorize ventilations in homes today include:

Exhaust ventilation systems

These tend to work by depressurizing a building. When the inside air pressure is reduced to a figure that is lower than the outdoor air pressure, these home ventilation systems will extract the air on the inside of the home while another make-up air will infiltrate the leaks on the shells of the building and into the intentional and passive vents. These types are usually more effective in areas with cold climates.

When used in areas with warm and humid climates, depressurization may remove the moist air and into the structures wall cavities. This air may condense in such area leading to moisture damage.

Balanced home ventilation systems

When these are designed and installed in the right manner, they do not pressure or even depressurize the home. They work by introducing and exhausting an equal amount of fresh air from the outside and the polluted air on the inside in equal portions. The balanced ventilation systems usually consist of 2 fans and 2 duct systems. This ensures a good distribution of the fresh air by ensuring that the supply as well as the exhaust vents are in the right place.

Energy recovery systems

These tend to cost more as compared to the other two options. in most cases simplicity is the most important thing when it comes to home ventilation systems. In order to minimize the installation costs, most of the systems tend to share the ductwork. For the houses that are trying to recover the energy that is in the exhaust system, there may be no need for any additional costs.
