Fresh Air Ventilation Systems are installed in houses to ensure the availability of fresh air within the confined spaces of the house. It helps to maintain low temperatures indoors and also that air provided is clean and free from any contaminants or pollutants.
Ventilation aims to provide oxygen-rich air so that any harmful substances or gases present in the atmosphere around your house, like the high rate of carbon dioxide in the air can be neutralized. It also helps to improve the air quality index within a room or the house. It caters to the need of providing enough oxygen supply for the combustion purpose of the furnace as well.
Ventilation systems are also used for the purpose of cooling the environment within a room or house. If enough ventilation is provided within a house, the need to use electrical appliances for the same will be reduced. This can help save electricity and non-renewable sources of energy.
Depending on the type of facility that has to be ventilated, there are four basic types of ventilation systems available. They are as mentioned,
- Exhaust-only ventilation system:- Small exhaust fans are used, usually in the kitchen and the bathrooms to remove the moist stale air. Small vents or ducts are responsible to provide fresh air supply into the house.
- Supply-only mechanical ventilation system:- A fan is used to supply fresh air into a room. Air supply may be directed to a single location and then distributed by using ducts. Stale air usually escapes through small vents or leaks in the system.
- Balanced ventilation system:- Two separate fans are used to drive the inlet and outlet air flow. They can be controlled with respect to where the outlet air is released and from where the inlet air is extracted.
- Balanced ventilation system with heat recovery:- Two separate fans are placed near each other for air-to-air heat exchange. The heat exchange is done so that the outlet air can complement the inlet air that will enter the house.
Living and breathing fresh air accompanied by a little exercise can help you stay healthy and fit. Some of the Health Benefits of Residential Fresh Air Ventilation Systems are as mentioned:-
- It strengthens the immune system.
- It improves blood pressure.
- It improves the heart rate.
- It cleanses the lungs.
- It helps improve the digestive system.
- It gives more energy and makes a person happier.
Building a Ventilation system primarily depends on the following factors:-
- Ventilation Rate.
- Airflow Direction.
- Air Distribution or Pattern.
Ventilation Rate is the amount of air that can be provided in a room or house from the outside environment. Airflow Direction is the direction in which the air flows in that particular area or building. Air Distribution or Pattern is the way in which air should be reaching each confined corner of the house. While doing so, it should also be able to remove the harmful contaminants present in those spaces.
Thus, the benefits of fresh air can be availed by using a residential fresh air ventilation system.
